    CROSS REFERENCE TO RELATED ORDERS
    [001] This application claims the benefit of the US Patent Application. 12 / 943,843, filed on November 10, 2010, which is incorporated here in its entirety by this reference to it. BACKGROUND OF THE INVENTION FIELD OF THE INVENTION
    [002] The present teachings refer to inkjet printers and, more particularly, they refer to roll to roll inkjet printers having a printhead using light emitting diodes (LEDs). BACKGROUND
    [003] Historically, roll-to-roll inkjet printers have been used to create prints that are seen over long distances, such as for paper or vinyl frame prints. Such prints do not typically need to be of high quality and the technology used for many years has been solvent based inks.
    [004] More recently, UV ink technology has been applied to roll-to-roll inkjet printers, which has enabled the printing of a wider range of substrates and in better print quality. For example, figure 1 shows a first exemplary roll-to-roll printer 10 having UV curing 24. In the exemplary printer 10 seen in figure 1, a substrate 14 is moved 18 such as on an input roll 16, a plurality of rollers 12, through a cooling mechanism 28 and an output roller 28. A print carriage 20 comprising one or more inkjet heads 22 applies ink to the substrate 14 when it passes over the rollers 12.The ink on the substrate 14 it is then cured by one or more UV 24 curing lamps, which can be located on the cooling mechanism 26.
    [005] Although such UV printers have provided adequate quality for a limited range of printing applications, UV light sources 24 generally heat substrate 14 and surfaces close to pressure mechanisms to as much as 65.5 to 93 ° C (150 to 200 degrees Fahrenheit (F)), which can generally cause problems both for the precision of placing the UV 22 curable ink drops and for the precise positioning or movement of the substrates 14. For example, the heat from the sources of UV light 24 forms rapidly through substrates 14 and rollers, which can cause many substrates, especially thin or temperature sensitive substrates, to stretch or bend, making it difficult for the substrate gap to the printhead to remain accurate or constant. Such heat formation typically restricts the types of substrates 14 that can be used in UV printers.
    [006] Printers having UV light sources 24 can provide substrate cooling, such as with a cooled press table or other cooling mechanism 28, where the cooling water can typically be circulated to cool a press table. metal in contact with the substrate 14. Also, some UV printers have cooling water pass tubes that resist UV absorption, located between the UV light sources 24 and the substrate 14, to reduce heat than otherwise way would reach the substrate.
    [007] There is a continuing need for higher quality prints, with higher resolution that has been driven by the desire to produce a wide variety of printing products, such as, but not limited to, any point of purchase (POP) items, labels and packaging, where close viewing is a requirement. Increases in printer speed are an ongoing requirement that is driven by consumer costs and competition.
    [008] In recent years, this has driven a higher cost of printer design, as more printheads have often been needed, such as to increase printing speed and / or to increase printer tolerances. Also, cooled press tables have been used, such as with thermoelectric devices, or the region near the UV lamps has been cooled, such as by passing cooling water in front of the lamps, such as to provide a quality of movement for the strip expanded substrates, for example thinner and / or temperature sensitive substrates and the requirement for improved drop placement accuracy.
    [009] Although such UV printers have provided adequate quality for some printing applications, UV 22 light sources generally heat both the substrate and the surface close to the drum to as much as 65.5 to 93 ° C (150 to 200 degrees Fahrenheit (F)). For mercury vapor printing systems, substrates are generally heated to as much as 65.5 to 104 ° C (150 to 220 degrees Fahrenheit (F)), depending on such factors as lamp type, power output and adjustment of velocity. Even with cooling and a low force adjustment, mercury vapor printing systems generally heat the substrate to over 37.7 ° C (100 degrees F).
    [0010] It would be advantageous to provide a printing system that can produce a wide variety of printed matter with high resolution that can be seen close by, such as for items at the point of purchase (POP), labels and packaging. The development of such a printing system would constitute a major technological advance.
    [0011] Also, it would be advantageous to provide such a printing system that could produce a wide variety of printed matter on a wide variety of substrates, such as for thin and / or temperature sensitive substrates. The development of such a printing system would constitute an additional technological advance.
    [0012] In addition, it would be advantageous to provide such a printing system that could produce a wide variety of printed matter on a wide variety of substrates, without the need to cool the press table. The development of such a printing system would constitute an additional technological advance.
    [0013] Some recent flatbed printers having flatbed presses have used LED curing for the applied ink. Figure 2 shows a second exemplary inkjet printer 30 having LED curing 38 for a flat press table 32. For example, substrate media 40 can be placed or positioned between a printhead assembly 34 and a press table 32, wherein the printer 30 comprises one or more printheads 36 and one or more LED light sources 38.
    [0014] Although such flatbed 30 printers have begun to implement LED curing, such flatbed configurations are often expensive and can only provide a limited range for printed output.
    [0015] Therefore, it would be advantageous to provide a printing system that could cost effectively produce a wider variety of printed matter through a wider range of substrates. The development of such a printing system would constitute an additional technological advance. SUMMARY
    [0016] An optimized printing system comprises a drum structure, a printing carriage to release LED curable ink from it, such as one or more printheads, and one or more LED light sources to cure loose ink. Some embodiments may preferably also comprise one or more LED fading stations, such as to control, reduce or stop the spread of the ink droplets. Also, some types of printer may comprise a release mechanism or an inert gas, for example, nitrogen, or another gas that is at least partially devoid of oxygen, between the LED's power source and the substrate. The revealed LED printing structures can provide higher quality and / or lower cost when compared to prior art systems, for a wide variety of media output, such as for, but not limited to, super large format output ( SWF), wide format output (WF), labeling, packaging or displays or signage at the point of sale.

    [0030] Figure 3 is a schematic side view of a first exemplary mode of a light-emitting diode (LED) roller to roller printer 50, for example, 50a. Figure 4 is a schematic side view of a second exemplary embodiment of a 50b LED to roll to roll printer. Roll to roll printers with LED 50, for example, 50a (figure 1), 50b (figure 2), comprise a drum structure 54 that provides a printing press table for a substrate 53, in combination with a printing carriage 56 and one or more curing sets with LED 58.
    [0031] As seen in figure 3 and figure 4, the print drum 54 is typically configured to receive a substrate 53 for printing, where substrate 53 is movable 110 (figure 7, figure 8) between an unrolling roll 52 and a rewind roller 60. The print drum 54 is cylindrical, having a diameter 55, which can preferably be sufficiently sized to produce a curved surface 57 where one or more printheads 72 (figure 5, figure 6) are located at a head height 142 (figure 9), for example, within 1.5 to 2 mm, from the surface of the substrate 53.
    [0032] The printing drum 56 may preferably be at least partially comprised of a material with good dimensional stability, such as, but not limited to any ceramic, a carbon fiber compound, nickel alloy (e.g. , Hastelloy C® available from Haynes International Inc., Kokomo, IN), stainless steel, titanium or its alloys. For some embodiments of roll-to-roll drum printers with LED 50, the print drum 54 can preferably be comprised of an internal structure 114 (figure 7, figure 8), such as a cylindrical core comprising a polymer and / or metal, with an outer shell 114 (figure 7, figure 8), for example, natural or synthetic rubber, a polymer, ceramic, a carbon fiber compound, nickel alloys (for example, Hastelloy C®), alloys stainless steel, titanium or its alloys. The print drum 56 can preferably be at least partially hollow, such as comprising holes or cameras 117 defined therein, in which weight, cost and / or rotational inertia can be controlled. Print drums 56 which are at least partially hollow 117 provide rapid cooling as the drum rotates 110 (figure 7), thereby reducing or eliminating the formation of heat over time.
    [0033] During the printing process, for example, 220 (figure 12), the print drum can preferably be controllably graduated 112 (figure 7) or kept in continuous rotation 110. For exemplary LED drum printers 50 having rotation 110 continuous, for example, at a defined speed, the printer 50 can preferably trace the image signal or the data file 145 to correctly form the image 242 (figure 13), such as through a central controller 144 ( figure 9) and / or through a local control module of the ink system 88 (figure 6). In some exemplary embodiments 50, the substrate 53 moves 110 slowly, while the heads 72 move quickly, for example, 102, 104 (figure 7), such as parallel to the geometric axis of the drum 103 along one or more tracks. support 84, in which the image 242 is formed, considering the combined movements, for example, 110, 102.
    [0034] Drum printers with LED 50 provide precise positioning and movement of the substrate 53, resulting in precise placement of the drop 72, since the substrate 53 is inherently wound over a large contact region 69 of the convex cylindrical contour 94 (figure 6) of the print drum 54, which is typically much larger than the region of the print zone 68 (figure 3). Also, substrates 53 in LED 50 drum printers are not deformed by high temperatures, since LED 58 curing stations operate cold.
    [0035] Substrate 53 is placed around drum 54 and held in place by cylindrical constricting rollers 62, for example, 62a, 62b. In the first exemplary embodiment of the roll-to-roll drum printer with LED 50 seen in figure 3, the constricting rollers 62a, 62b are located towards the bottom of the print drum 54, such as at a feed input point 65a and a feed point 65b power outlet. After substrate 53 is located on print drum 54, friction 176 (figure 9), such as between substrate 53 and print drum 54, and / or the tension applied by the constricting rollers 62, ensures that substrate 53 does not moves or stretches within the print zone 68. The second exemplary embodiment of the LED roll-to-roll drum printer seen in Figure 4 still comprises one or more tension rollers 64, such as a first tension roll 64a between the first constricting roll 62a and unwinding roll 52 and / or a second tension roll 64b between the second constricting roll 62b and the rewinding roll 60.
    [0036] The motion control for the print drum can typically comprise an encoder 146 (figure 9) and a corresponding motor 148 (figure 9), wherein encoder 146, as linked to or associated with a central controller 144, produces a signal or otherwise communicates with the motor 148 and wherein the motor 148 is associated with a driving mechanism 150 to move 110 the print drum 54, for example, as directly or indirectly. In some embodiments of the system 50, the print drum 54, together with the substrate 53, can preferably move, for example, grading 112 (figure 7, figure 8), within a range of at least 0.25 of a diameter pixel with respect to accuracy. For example, for a roll-to-roll printer with LED 50 having a print resolution of 1,200 dots per inch (dpi), movement 110 may preferably be graduated or otherwise controlled 112 to be equal to or less than 0.00508 mm (0.0002 inches).
    [0037] The structure of the drum 54, therefore, provides a same printing press having a convex cylindrical contour 94 (figure 6) within a printing zone 68, where the drum 54 is also used to drive the substrate 53 in combination with a print carriage 56 having a corresponding cylindrical contour 94 and one or more curing stations with LED 58. Curing stations with LED 58 allow curing 232 (figure 12) of loose ink 226 (figure 12) on a substrate 53 located on the surface of the drum 54, while inherently reducing or eliminating the heat load on the substrate 53 and / or the drum 54, as compared with UV lamps 24 (figure 1). Current suppliers of LED sensitive inks include 3M, Inc. of St. Paul MN; ImTech Inc. of Corvallis, OR; Agfa Graphics, from Mortsel, Belgium and Sun Innovations, from Novosibirsk, Russia.
    [0038] A current exemplary modality of the 50 LED drum printing system, operating at full power, shows a substrate 52 temperature range of approximately 21 to 37.7 ° C (70 to 100 degrees F), while the temperature of the substrate 52 drum roll is less than that of substrate 53, when printing and moving the movement on the drum roll 54, while the temperature of the drum roll 54 shows a temperature of approximately 26.6 ° C (80 degrees F) when the substrate 53 is not present.
    [0039] In different printing systems, a key temperature is on the substrate surface, for example, 14, 40 53, when a dark or black image 242, for example, loose ink 242, is present, as long as dark colors absorb more heat , where differential expansion due to variable print density can occur. Such differential expansion can result in pleating or deformation of the substrate in previous printing systems, such that the substrate does not move correctly and / or can reach the heads.
    [0040] The curing stations with LED 58, therefore, reduce or eliminate the pleating, deformation or other changes in the substrate gap 59, 142, which can occur otherwise with other sources of curing energy, for example, UV lamps 24. Also, roll-to-roll printers with LED 50 retain precise control of substrate movement, since the operating temperature of the print drum 54 and substrate 53 is inherently more consistent, when compared to printers having other energy sources for curing, for example, UV lamps 24.
    [0041] Drum structure 54, in combination with LED curing stations 58, provides high print quality for a wide variety of printed matter and is cost effective when compared to previous printing systems. Also, the drum structure 54 and the associated mechanisms, for example, rollers 52,60,62,64, are robust in nature and can be readily implemented for a wide variety of print formats and applications.
    [0042] Figure 5 is a schematic bottom view 70 of an exemplary printer carriage 56 for a roll-to-roll printer with 50 LED. Figure 6 is a schematic side view 80 of an exemplary printer carriage 56 for a roller printer. roller with LED 50. The exemplary printer cartridge 56 seen in figure 5 comprises one or more printheads 72, for example, 72a-72m, as for providing a plurality of color channels, such as for, but not limited to color printing of the CMYK process, comprising cyan (C), magenta (M), yellow (Y) and black (K); and / or one or more immediate colors, for example, Pantone® colors. In some embodiments of the printing carriage 56, the geometric axis of the carriage 78 may preferably be perpendicular to the movement 110 (figure 7) of the substrate 53 and parallel to the geometric axis of the print drum (figure 7). In other embodiments of the printing carriage 56, the geometric axis of the carriage 78 may preferably be parallel to the movement 110 of the substrate 53, and perpendicular to the geometric axis of the printing drum.
    [0043] As seen in figure 6, the carriage 56 typically has a defined concave carriage outline 96, wherein the inkjets 98 of the printheads 72 are typically located at a defined height 59, 142 (figure 3, figure 9) the printing drum 54 having a corresponding convex cylindrical contour 94.
    [0044] The exemplary printheads 72 as seen in figure 5 and figure 6 are typically driven by local control electronics 88, an ink application system 90, for example, ink cartridges, and associated plumbing 92, in which drops of ink 172 (figure 9) are squirted in a controllable manner on the substrate 53, as in accordance with an incoming image signal 145 (figure 9).
    [0045] The exemplary print cartridge seen in figure 5 also comprises one or more curing stations with LED 58, for example 58a, 58b, where each of the curing stations with LED 58 comprises LED elements 184 (figure 10) to apply light 250 (figure 13) to cure, that is, dry, the loose paint 172 located on the substrate 53. As seen in figure 5, the most common system modalities 50 comprise two or more curing stations with LED 58, for example 58a, 58b, as located at opposite ends 60a, 60b of the print carriage 56. Although the exemplary print carriage 56 shown in figure 5 comprises LED curing stations 58, for example, 58a, 58b attached to opposite ends 60a, 60b, LED curing stations 58 can alternately be located separately from the print carriage 56 within the LED 50 roll to roll printing system. LED curing stations 58 typically provide complete ink curing 172, as attracted through several specified passages of substrate 53 in relation to one or more curing stations with corresponding LED 58, and the strength level can be precisely controlled, such as through the curing control with LED 152 (figure 9).
    [0046] The exemplary print cartridge seen in figure 5 further comprises one or more LED fading stations 76, for example 76a-76e, such as between one or more printhead banks 72, where each of the printing stations LED fading 76 comprises LED fading elements 204 (figure 11) to apply light 246 (figure 13) to control or stop the spread of loose ink droplets 172 located on substrate 53. In some types of roll-to-roll printers with LED 50, the number and frequency of the weakening stations 76 can be varied from just one weakening station 76, such as placed in the center of the print carriage, for example, between the curing stations with LED 58, to a plurality of LED weakening stations 76, for example, having an LED weakening station 76 for each head bank 72. LED weakening stations 76 can preferably be thin and / or have strength relatively weak, such as when compared to LED curing stations 58, where LED weakening stations 76 can provide sufficient strength to control or stop the spread of loose ink droplets 172 (figure 9). The LED fading stations 76 can therefore reduce the negative impact on the print quality of the spread of the differential droplet and ink / ink interactions.
    [0047] Roll to roll printers with LED 50 provide precise drop placement, controlled drop spreading and minimal drop interaction, thus producing excellent drop direction capability and print quality, such as through: • clamping media 53 for drum 54, • precise graduated movement, • correct choice of printhead, and • optional weakening.
    [0048] As seen in figure 6, the print carriage can be supported with respect to the print drum 54 by one or more tracks 84 which are mounted parallel to the drum 54, as well as by corresponding rail support mechanisms 86. The print carriage 56 can be fixedly attached to the rail 84, such as for a print carriage 56 that extends across the width of the print drum 54. Alternatively, the print carriage 56 can be movable along rail 84, just as for a carriage printer 56 that sweeps across the width of the substrate 53 located on the print drum 54.
    [0049] Figure 7 is a schematic partial perspective view100 of a print drum and scan carriage 56 for a roll-to-roll printer with exemplary LED 50. Figure 8 is a schematic partial perspective view 120 of the carriage printer 56 extending through a print drum 56 to a roll-to-roll printer with an exemplary LED 50.
    [0050] As seen in figure 7, a printing carriage 56 can be moved 102, preferably by scanning in relation to the printing drum 54, such as by graduated increments of the carriage 104. The exemplary printing carriage 56, seen in the figure 7, is movably mounted on a support rail 84 and can be moved 102, preferably through a carriage strip 108, where the printheads 54 can drop drops of ink 72 across a usable image width of the substrate 53, which can extend over the entire width 106 of the substrate 53 or can be controllably limited to a region 122 (figure 8) within the width of the substrate 106, such as to provide a minimum margin 124 on the outer edges of the substrate substrate 53. LED 50 drum printers having a raster print 54 drum, that is, mobile, for single pass printing, can be used for a wide variety of printing applications, such as, not limited to panels, signage apply POP information, for example, wide format (WF) and / or super wide format (SWF). For example, a scan-through print carriage 56 is readily provided for substrate applications having a substrate width 106 of up to 127 cm (50 inches), as is generally required for labeling, panels, signage and / or POP applications.
    [0051] The exemplary print carriage 56 seen in figure 8, as comprising a printing plate 56, extends through the printing drum 54 and is fixedly mounted on one or more support rails 84, where stationary print heads 72 , for example, a plurality of printheads 72 for applying a plurality of colors, controllably applies drops of ink 172 across the usable width of the image 122 of a substrate 53. The usable width of the image 122 of a substrate 53 can extend over the entire width 106 of the substrate 53 or can be controllably limited to a region within the substrate width 106, such as to produce a minimum margin124 on the outer edges of the substrate 53. LED drum printers 50 having a stationary print drum 54 for pass-through printing can be used for a wide variety of printing applications, such as, but not limited to, labeling and packaging printing. For example, a stationary single-pass printing carriage 56 is easily supplied for substrate applications having a substrate width 106 of 30.5 cm (12 inches), as generally used for labeling.
    [0052] The exemplary printing carriage or plate 56, seen in figure 8, can comprise a long formation of LEDs 182 (figure 10) that extends across the width of the drum 54, a given distance from the final formation of the printhead, such as as before an exit or constricting narrowing roller 62. The exemplary printing carriage or plate 56 seen in figure 8 may alternately comprise a plurality of LED formations 182.
    [0053] For different types of drum printers with LED 50, the diameter 55 of the print drum 54, having a corresponding convex contour 96, and the corresponding concave contour 97 of the print carriage 56 can be chosen, preferably, based on one or more other parameters of the LED drum printer, such as, but not limited to, the printer carriage configuration 56, for example, scanning or stationary, and / or the configuration of the printheads 72, for example, perpendicular to the direction of travel of the substrate 110, such as for a stationary single-pass LED drum printer 50 having a carriage extending through the print drum 54 or parallel to the direction in which the path of the substrate 110, such as for a printer drum with scan LED 50 having a carriage moves 102 (figure 7) through the print drum 54.
    [0054] As the printheads 72 typically comprise a large number of inkjet nozzles 98, the distance between different nozzles 98 for substrate 53 and the print drum 54 may vary slightly for some modes of the printer 50. As an example , for printheads 72 that have a flat head face 99 (figure 6), nozzles 98 located near the center of face 99 may be closer to substrate 53 than nozzles 98 that are located far from the center of the head face 99. The trajectory time for ink droplets 172 (figure 9) increases based on the distance between the nozzles 98 and the substrate 53. Some modalities of the 50 LED drum printers are preferably configured to minimize differences in the trajectory, where the distance between the ink nozzles 98 and the substrate 53 is relatively similar across the printheads, for example, such as, but not limited to, having a nozzle distance to the substrate from 1 mm to 1.4 mm or alternately have a maximum differential distance, for example, 0.5 mm. In some types of printers with LED 50, the length of the printheads 72 and the diameter 55 of the print drum 54 can be chosen preferably to minimize such differences in travel time. Also, some types of printers with LED 50 have heads configured at a saber angle to minimize differences in trajectory time. Some types of printers with LED 50 can preferably compensate for differences in trajectory time, for example, through the local control of the ink system 88 and / or through a central controller 144 (figure 9), such as by controlling the regulation from the discharge of drop 226 (figure 12) to one or more nozzles 98. For some modalities of drum printers with single-pass LED 50, where the heads 72 are placed perpendicular to the movement of the drum 110, such length considerations are little concern, for example, since the distance between the ink nozzles 98 and the substrate 53 is well within a maximum differential distance.
    [0055] Figure 9 is a schematic view 140 of subsystems controls for some types of roll-to-roll printers with LED 50, such as for the controlled movement of the print drum 54, controlled application of the ink drops 172 and controlled curing with LED 232 (figure 12). The exemplary system modality seen in figure 9 also preferably comprises one or more stations of inertia 160 and one or more weakening stations 76, with associated controls.
    [0056] As seen in figure 9, the movement of a print drum 56 may comprise an encoder 146 and a corresponding motor 148, wherein the encoder 146, as linked or associated with a central controller 144, produces a signal or otherwise form communicates with the motor 148 and in which the motor 148 moves the print drum 54, for example, as directly or indirectly through a drive mechanism 150, to move 110 substrate 53, such as in graduated increments 112, by example, to produce a desired resolution with the loose ink droplets 172.
    [0057] As also seen in figure 9, an ink delivery system 90, such as comprising ink cartridges, and associated plumbing 92, is typically driven by a central controller 144 and / or by local control 88 (figure 6) to squirt controllably drops of ink 172 from one or more of the printheads 72 on the substrate 53, such as according to an incoming image signal 145.
    [0058] As also seen in figure 9, one or more stations cure with LED 58, for example 58a, 58b, are controlled by any one of a central controller 144 and / or cure control with LED 152, to emit the light from one or more LED elements 184 (figure 10) to cure, i.e., dry, the loose ink droplets 172 located on the substrate 53.
    [0059] The exemplary LED roll-to-roll printer 50 seen in Figure 9 preferably comprises one or more LED weakening stations 76, as controlled by any of a central controller 144 and / or LED weakening control 154, to emit 228 (figure 12) light 246 (figure 13) from one or more LED fading elements 204 (figure 11), as well as to provide sufficient strength 228 to control or stop the spreading of loose ink drops 172 located on the substrate 53.
    [0060] Roll-to-roll printers with LED 50 may further comprise means for releasing a gas 157, for example, as comprising either an inert gas or a gas at least partially devoid of oxygen, between the curing stations with LED 58 and substrate 53. The similar release of a gas can preferably be provided at or near one or more weakening stations 76, to similarly release 164 a gas 157 between the weakening stations of LED 76 and the substrate 53 The exemplary LED roll-to-roll printer 50 seen in Figure 9 preferably comprises a container 156 for storing and releasing a gas 157, such as, but not limited to, an inert gas, for example, nitrogen. Gas 157 is typically transported over lines 158 to stations of inertia 160 which are located at or generally adjacent to the corresponding LED curing stations 58. The release of gas 157 can preferably be controlled by a central controller 144 and / or inertia control 162, to introduce a layer 164 of gas 157 between LED curing stations 58 at or near the print carriage 56, and the substrate 53 located on the outer surface 94 of the print drum 54, such as to empty the oxygen level in the printing zone, for example, to improve the quality of cured ink or to reduce the force required to cure loose ink 172 .
    [0061] Figure 10 is a schematic view 180 of a set of cure treatments with exemplary LED 58, which typically comprises a formation 182 in one or more LED elements 184, as mounted or otherwise fixed to a body of the assembly curing 186. The exemplary LED formation 182 seen in figure 10 comprises a plurality of LED elements 184 arranged in rows 188 and columns 190. Since LED elements 184 are typically robust, LED curing station assemblies 58 safely provide LED curing over an extended lifetime. Also, since LED curing station assemblies 58 often comprise a plurality of LED elements 184, LED curing assemblies 58 can preferably provide redundancy. For example, even if some of the LEDs fail, most LED elements continue to operate to produce the 232 cure, thereby reducing loss of output and / or preventing printer shutdown. Current suppliers of LED light sources for curing and / or weakening include Exfo, Inc., of Quebec, Canada; Phoseon Technology, of Hillsboro, OR; Integration Technology North America of Chicago, IL and Baldwin Technology Co. of Shelton, CT.
    [0062] Figure 11 is a schematic view 200 of an assembly of the exemplary LED weakening station 76, which typically comprises a formation 202 in one or more LED elements 204, as mounted or otherwise attached to a body of the assembly weakening 206. The exemplary LED weakening formation 202 seen in Figure 11 comprises a plurality of LED weakening elements 204 arranged in rows 208 and columns 210. Since LED elements 204 are typically robust, the LED weakening 76 safely provides LED weakening 228 for an extended duration. Also, since LED weakening station assemblies 76 often comprise a plurality of LED elements 204, LED curing assemblies 76 can provide redundancy for the weakening functionality. For example, even if some of the LEDs 204 fail, most of the LED elements 204 continue to operate to produce the weakening 228, thus reducing output loss and / or preventing printer shutdown.
    [0063] Figure 12 is a flow chart of an exemplary process 220 associated with a roll-to-roll printer with LED 50. A printer with LED 50 is provided 22, first, where printer 50 comprises a cylindrical print drum 54, a or more LED curing stations and a carriage 56 defining a generally concave region 96 which generally corresponds to the outline of the outer surface 94 of the print drum 54, wherein the carriage comprises one or more printheads 72 having the jets 98 located on the generally concave surface 96. A substrate 53 is then fed 224 onto the print drum in relation to the print carriage 56 and drops of ink 172 are released 226 onto the substrate 53, as corresponding to an input signal or data file 145, for example, to create an image, text, pattern or any combination of these. For LED printer types 50 having one or more weakening stations 76, one or more of the stations 76 can be energized 228, such as in coordination with the ink release 226, the roller movement 54 and or the movement of the printer carriage. printer 56, for example, scan 102, to decrease or stop scattering of loose ink 172. For LED printer types 50 having one or more inertia stations 160, one or more of the inertia stations 160 can provide 230 preferably inert gas 157, such as in conjunction with energizing 232 of one or more LED curing stations to cure loose ink 172.
    [0064] Figure 13 is a partial close view 240 of the datinta, weakening and curing application for a printer with an exemplary LED 50. For example, ink droplets 172 are squirted by the printheads 72 onto the substrate 53. For LED printers 50 having weakening stations 76, weakening elements 204 can be controllably energized to emit weakening energy 246, such as to reduce or stop the spread of loose ink 242, for example, a printed image 242, on substrate 53 LED curing stations 58, for example, 58a, 58b, are controllably energized to emit curing energy 250, to cure loose ink 242 on substrate 53. Also, for LED printers 50 having curing stations inertia 160, the gas can be controllably distributed between the curing stations and the substrate 53. Similarly, inertia stations 160 can preferably distribute the gas 157 between the weakening stations image 76 and substrate 53, if desired.
    [0065] 50 LED roll to roll printers combine 58 LED curing systems with drum-based printer designs to take advantage of the low cure temperature provided by 58 LED curing sets. The roll to roll printers with LED 50 they can also preferably provide weakening stations 76, for example, weakening assemblies with LED 76, to decrease or stop the flow of loose ink. Roll-to-roll printer configurations with LED 50 are relatively less costly to manufacture than previous printer designs and provide high quality printing, as may be required for a wide variety of printing applications, such as, but not limited to any of POP, labeling, packaging and / or realistic photographic applications.
    [0066] The cold LED lamp elements 184 allow pressure on the drum without heating the drum, thus preventing or reducing changes in the substrate gap due to temperature changes and providing precise control of the movement of the substrate. The use of drum 54 significantly simplifies the design of the printer 50 to allow for improved print quality and cost savings.
    [0067] Some types of drum printers with LED50.tas such as, but not limited to, the super large format SWF) and wide format (WF) printers, comprise two sets of rollers to control the movement 100 of the substrate 53 and a table of central drum press 54 to support substrate 53 during the printing process. The rollers 62, 64 are preferably comprised of rubber and may preferably have a high dimensional tolerance, to provide uniform and precise driving through a substrate 53, such as for substrates 53 having a width 106 (figure 7, figure 8) of up to 5 meters.
    [0068] In many previous printer designs, changes in pressure on substrates can create inaccuracies in movement that can lead to drop placement errors, while substrate slip can also be a factor, such as when using different substrates. In contrast to previous press table designs, LED 50 drum printers can preferably reduce or eliminate movement errors due to variations in the press table surface, material formation and / or thermal variations.
    [0069] Although some mechanisms are described here with respect to specific modalities of LED 50 printers, some of the mechanisms can be used readily within different printing environments. For example, although LED fading sets are described here as being used for roll-to-roll LED printers, such LED fading sets can provide fading for other configurations, such as for other printers having UV curing, where the spreading of such paints can be reduced or stopped in a controllable way through the weakening of LEDs.
    [0070] Thus, although the invention has been described in details with reference to a particular preferred modality, people having knowledge of the technique to which this invention belongs will find that various modifications and improvements can be made without departing from the spirit and scope of claims that follow.
