    “METHOD FOR MANUFACTURING AN IMAGE PRINTING ELEMENT IN RELIEF”
    Field of invention
    The present invention generally relates to a method of preparing an embossed flexographic printing element to provide an improved embossed structure thereon.
    Fundamentals of the invention
    Flexography is a printing method that is commonly used for high volume operations. Flexography is used for printing on a variety of substrates, such as paper, cardboard stock, corrugated board, films, foils and laminates. Newspapers and supermarket bags are prominent examples. Rough surfaces and cling films can only be economically printed using flexography. Flexographic printing plates consist of raised plates with image elements elevated above open areas. Generally, the plate is somewhat soft and flexible enough to wrap around a printing cylinder, and durable enough to print over a million copies. Such cards offer a series of advantages for the printer, based mainly on their durability and the ease with which they can be made.
    The corrugated board generally includes a corrugation means that typically consists of a layer of multi-grooved or pleated cardboard, called "corrugation", adjacent to a layer similar to paper or plain paper called a cover. A typical corrugated board construction comprises a corrugation layer disposed between two layers of cover. Other modalities may include multiple layers of undulation and / or coverage. The corrugated interlayer provides structural rigidity for the corrugated board. Since the corrugated board is used as packaging and formed in boxes and containers, the cover layer that forms an external surface of the corrugated board is often printed with identification information for the packaging. The outer covering layer often has slight indentations due to the irregular support of the underlying undulation layer.
    A problem that can be encountered when printing on corrugated cardboard substrates is the occurrence of a printing effect referred to as wave formation (and which is also known as bands, lines or ripples). Curling can occur when the coating is printed on the outer surface of the corrugated board, after the corrugated board has been assembled. The ripple effect is visible as dark print regions, that is, bands of higher density, alternating with regions of light print, that is, bands of lower density that correspond to the underlying corrugation structure of the corrugated board. The darkest impression occurs where the most
    Petition 870190088499, of 9/8/2019, p. 10/22
    2/10 high of the pleated inner layer structure supports the printing surface of the coating. The ripple effect can be evident in areas of a printed image that have color or tonal values where the dyed areas represent a fraction of the total area, as well as in areas of the printed image where the ink coverage is most complete. This ripple effect is typically most pronounced when printing with a flexographic printing element produced using a digital workflow process. In addition, increasing the printing pressure does not eliminate the lines, and the increased pressure can cause damage to the corrugated cardboard substrate. Therefore, other methods are needed to reduce vertical lines or curl when printing on corrugated board substrates.
    A typical flexographic printing plate as delivered by its manufacturer consists of a multilayered article made up of, in order, a backing layer; one or more unexposed photocurable layers; a protective layer or sliding film; and often a protective cover sheet.
    The backing sheet or backing layer provides support for the board. The backing sheet, or backing layer, can be formed from an opaque or transparent material, such as paper, cellulose film, plastic or metal. Preferred materials include sheets made from synthetic polymeric materials, such as polyesters, polystyrene, polyolefins, polyamides, and the like. Generally, the most widely used backing layer consists of a flexible film of polyethylene teraftalate. The backing sheet may optionally comprise an adhesive layer for more secure attachment to the photocurable layer (s). Optionally, an anti-halo layer can also be provided between the support layer and one or more photocurable layers. The anti-halo layer is used to minimize the halo caused by the diffusion of UV light within the non-image areas of the photocurable resin layer.
    The photocurable layer (s) can include any of the photopolymers, monomers, initiators, reactive or non-reactive diluents, fillers and dyes. The term photocurable refers to a composition that undergoes polymerization, crosslinking or any other hardening or curing reaction in response to actinic radiation, with the result that the unexposed parts of the material can be selectively separated and removed from the exposed parts (cured) to form a relief or three-dimensional pattern of the cured material. Preferred photocurable materials include an elastomeric compound, an ethylenically unsaturated compound that has at least one terminal ethylene group and a photoinitiator. Exemplary photocurable materials are shown in European patent application no. 0456336 A2 and 0640878 Al to Goss, et al., British Patent No. 1366769, US Patent No. 5,223,375 to Berrier, et al., US Patent No. 3,867,153 to MacLahan, US Patent No. 4,264,705 to Allen, US Patent No. 0 4,323,636, 4,323,637, 4,369,246 and 4,423,135

More than one photocurable layer can be used.
    Photocurable materials generally cross-link (cure) and harden through radical polymerization in at least some region of actinic wavelength. For use in the present invention, actinic radiation consists of radiation capable of effecting a chemical change in an exposed portion. Actinic radiation includes, for example, amplified (e.g., laser) and non-amplified light, particularly in the violet and UV wavelength regions. A commonly used actinic radiation source consists of a mercury arc lamp, although other sources are generally known to those skilled in the art.
    The sliding film consists of a thin layer, which protects the photopolymer from dust and increases its ease of handling, in a conventional (analog) plate manufacturing process, the sliding film is transparent to UV light. In this process, the printer removes the cover sheet from the blank element of the printing plate and places a negative over the top of the sliding film layer. The plate and negative are then subjected to UV saturation exposure through the negative. The areas exposed to light curing, or hardened, and the unexposed areas are removed (revealed) to create the embossed image on the printing plate. Instead of the sliding film, a matte layer can also be used to improve the handling of the board. The matte layer typically comprises fine particles (silica or similar) suspended in an aqueous binder solution. The matte layer is coated over the photopolymer layer and then allowed to air dry. A negative is then placed over the matte layer for exposure to subsequent UV saturation of the photocurable layer.
    In a digital plate or straight to plate manufacturing process, a laser is guided by an image stored in an electronic data file, and is used to create a negative in situ on a digital mask layer (that is, removable by laser ), which generally consists of a sliding film that has been modified to include an opaque radiation material. The parts of the removable laser layer are removed by exposing the mask layer to laser radiation at a selected wavelength and laser power. Examples of removable layers lasers are disclosed, for example, in US Patent No. 5,925,500 to Yang, et al., And US patent no. 5,262,275 and 6,238,837 to Fan, whose subject matter of which is incorporated herein by reference, in its entirety.
    After the graphic representation, the photosensitive printing element is revealed
    Petition 870190088499, of 9/8/2019, p. 12/22
    4/10 to remove the unpolymerized parts of the photocurable material layer and display the embossed image on the cured photosensitive printing element. Typical methods of disclosure include washing with various solvents or water, often with a brush. Other possibilities for the development include the use of an air or heating knife plus a blotter. The resulting surface has a raised pattern that reproduces the image to be printed. The relief pattern typically comprises a plurality of dots, and the shape of the dots and the depth of the relief, among other factors, affect the quality of the printed image. After the embossed image is developed, the embossed image printing element can be mounted on a press and printing started.
    Photocurable resin compositions typically cure through radical polymerization, under exposure to actinic radiation. However, the curing reaction can be inhibited by molecular oxygen, which is typically dissolved in resin compositions, due to the fact that oxygen functions as a radical scavenger. It is therefore desirable that the dissolved oxygen be removed from the resin composition prior to exposure to the image, so that the photocurable resin composition can be cured more quickly and uniformly.
    The removal of dissolved oxygen can be completed, for example, by placing the photosensitive resin plate in an atmosphere of inert gas, such as carbon dioxide gas or nitrogen gas, overnight, prior to exposure, in order to to displace dissolved oxygen. A disadvantage observed for this method is the fact that it is inconvenient and uncomfortable and requires a large space for the device.
    Another approach that has been used involves subjecting the plates to a preliminary exposure (i.e., impact exposure) of actinic radiation. During impact exposure, a low-intensity pre-exposure dose of actinic radiation is used to sensitize the resin before the plate is subjected to the main exposure dose of higher intensity of actinic radiation. The impact exposure is applied to the entire area of the plate and consists of a short exposure of a low dose of the plate that reduces the concentration of oxygen, which inhibits the photopolymerization of the plate (or other printing element) and helps to preserve characteristics thin (ie, highlighted points, thin lines, isolated points, etc.) on the finished board. However, the pre-sensitization step can also cause shaded tones to fill, thereby reducing the halftone tone range in the image.
    Impact exposure also requires specific conditions that are limited to dissipating dissolved oxygen, such as exposure time, intensity of irradiated light, and the like. In addition, if the photosensitive resin layer is more than 0.1 mm thick, the low light from the low intensity impact exposure dose does not sufficiently reach certain parts of the photosensitive resin layer (that is, the side
    Petition 870190088499, of 9/8/2019, p. 13/22
    5/10 of the photosensitive layer that is closest to the substrate layer and farthest from the source of actinic radiation), in which the removal of dissolved oxygen is insufficient. In the subsequent main exposure, these parts will not heal sufficiently due to the remaining oxygen. Other efforts have involved special plate formulations alone or in combination with impact exposure.
    For example, US Patent No. 5,330,882, Kawaguchi, whose subject matter is incorporated by reference in its entirety, suggests the use of a separate dye that is added to the resin to absorb actinic radiation at wavelengths of at least 100 nm removed from the lengths waves absorbed by the main photoinitiator. This allows separate optimization of primer quantities for impact and main initiators. Unfortunately, these dyes consist of weak initiators and require extended impact exposure times. In addition, these dyes sensitize the resin to regular ambient light, so the inconvenient yellow safety light in the work environment is required. Finally, the approach described by Kawaguchi employs conventional broadband-type sources of actinic radiation light for impact exposure and thus also tends to leave significant amounts of oxygen in the lower layers of the resin. US patent No. 4,540,649, Sakurai, incorporated herein by reference in its entirety, describes a light-curing composition containing at least one water-soluble polymer, a light-curing initiator and a condensation reaction product of Nmethylol acrylamide, N-methylol methacrylamide , N-alkyloxymethyl acrylamide or N-alkyloxymethyl methacrylamide is a melamine derivative. According to the inventors, the composition eliminates the need for pre-exposure conditioning and produces a chemical and thermally stable plate.
    Other efforts have focused on adding an oxygen scavenger to the resin composition to suppress the action of oxygen. The use of oxygen sequestration in resin systems is described, e.g., in US patent n. 3,479,185 to Chambers, Jr. and US Patent No. 2 . 4,414,312 to Goff et al., Whose subject of each or both are incorporated herein by reference, in their entirety. However, all of these methods are still deficient in the production of an embossed image printing element that produces an upper dot structure, especially when designed for printing corrugated card substrates. Thus, there is a need for an improved process for preparing embossed image printing elements with improved embossing structure similar to or better than the embossing structure of a typical analog workflow process for printing on substrates of corrugated cardboard.
    Summary of the invention
    It is an objective of the present invention to provide an embossed image printing plate that produces a good result when printing on card substrates

    Another objective of the present invention is to produce an embossed image printing plate that reduces printing curl when printing on corrugated cardboard substrates.
    Another objective of the present invention is to create an upper stitch structure in an embossed image printing element in terms of the printing surface, margin definition, support angle, depth and stitch height.

    For this purpose, the present invention generally relates to a method of manufacturing an embossed image printing element from a blank photosensitive printing element, said blank photosensitive printing element comprising a removable mask layer laser placed on at least one photocurable layer, the method that comprises the steps of:
    a) selectively remove the removable laser mask layer by laser to create a mask in situ and discover the parts of the photocurable layer;
    b) exposing the blank print element removed by laser to at least one source of actinic radiation through the in situ mask to selectively crosslink and cure parts of the photocurable layer, where the diffusion of oxygen in at least one photocurable layer is limited by distributing a diffusion barrier over the top of the mask in situ and any uncovered parts of the photocurable layer before step (b), where the diffusion barrier has an oxygen diffusion coefficient of less than 6.9 x 10 -9 m 2 / s., Preferably less than 6.9 x 1 -10 m 2 / s., And most preferably, less than 6.9 x 10 11 m 2 / s. The diffusion barrier is preferably selected from the group consisting of:
    i) laminating a barrier membrane on the mask in situ and any uncovered parts of the photocurable layer before the exposure step; and ii) coating the mask in situ and any exposed parts of the photocurable layer with a layer of a liquid, preferably an oil, before the exposure step;
    wherein the barrier membrane and / or the liquid layer has an oxygen diffusion coefficient of less than 6.9 x 10 -9 m 2 / s., preferably less than 6.9 x 10 -10 m 2 / s., and most preferably, less than 6.9 x 10 -11 m 2 / s.

    Detailed description of the invention
    The inventors of the present invention have found that the shape and structure of a printing point has a profound impact on the way it is printed. Knowing this, an individual can manipulate the resulting shape of the print dots using the methods as described in this document. The use of these methods also acts to reduce the tendency to curl.
    In order to reduce printing curl when printing on corrugated cardboard substrates, the inventors of the present invention have found that it is necessary to (1) remove air from the exposure step; and, preferably, (2) change the type, power and incident lighting angle.
    Using these methods together produces a dot shape that is highly resistant to print curl and shows exceptional press latitude on the press (ie resistance to change in print gain when more pressure is applied during printing).
    The inventors in this document have discovered that the most important method of beneficially modifying the shape of printing points formed on a printing element is to remove or limit the diffusion of air in the photocurable layer during exposure to actinic radiation. The inventors have discovered that air diffusion in the photocurable layer can be limited by:
    (1) laminating a barrier membrane over the top of the flex plate to cover the mask in situ and any uncovered parts of the photocurable layer. The membrane can be applied most beneficially after the laser ablation used to create the mask in situ, but before exposure to actinic radiation. The inventors of the present invention have also discovered that this sheet can be used to impart a definite texture to the printing surface of the plate, which consists of an additional capacity and benefit thereof.
    (2) coating the mask in situ and any photopolymer layer not covered with a liquid layer, preferably an oil;
    wherein the barrier membrane and / or liquid layer has an oxygen diffusion coefficient of less than 6.9 x 10 -9 m 2 / s., preferably less than 6.9 x 10 -10 m 2 / s., and with the most preference, less than 6.9 x 10 -11 m 2 / s.
    Changing the type, power and incident lighting angle can also be useful in this regard and can be completed through multiple methods. For example, changing the type, power and incident lighting angle can be completed with the use of a collimator grid on top of the plate during the exposure stage. The use of a collimating grid for similar plates is described in relation to similar printing plates in US Patent No. 6,245,487 to Randall, whose subject matter is hereby incorporated by way of reference, in its
    Petition 870190088499, of 08/09/2019, p. 16/22
    8/10 totality. Alternatively, the use of point light or another semi-coherent light source can be used. These light sources are capable of changing the spectrum, energy concentration and incident angle to varying degrees, depending on the light source and exposure unit design. Examples of these point light sources include Olec Corporation's OVAC display unit and Cortron Corporation's cXact display unit. Finally, a completely coherent light source (for example, laser) can be used for exposure. Examples of laser light sources include U.V laser diodes. used in devices such as the Luscher Xpose imager and the Heidelberg Prosetter imager. Other light sources that can alter the type, power and incident angle of illumination can also be used in the practice of the invention.
    In one embodiment, the present invention generally relates to a method of manufacturing an embossed image printing element from a blank photosensitive printing element, said blank photosensitive printing element comprising a removable mask layer laser placed on at least one photocurable layer, the method that comprises the steps of:
    a) selectively remove the removable laser mask layer by laser to create a mask in situ and discover the parts of the photocurable layer;
    b) exposing the blank printing element removed by laser to at least one source of actinic radiation through the in situ mask to selectively crosslink and cure parts of the photocurable layer, where air diffusion in at least one photocurable layer is limited during the exposure stage using a method selected from at least one of:
    i) laminating a barrier membrane on the mask in situ and any uncovered parts of the photocurable layer, before the exposure step; and ii) coating the mask in situ and any uncovered parts of the photocurable layer with a liquid layer, preferably an oil, before the exposure step.
    A wide range of materials can serve as the barrier layer membrane. Three qualities that the inventors have identified in the production of effective barrier layers include optical transparency, low thickness and inhibition of oxygen transport. The inhibition of oxygen transport consists of a measure in terms of a low oxygen diffusion coefficient. As noted, the oxygen diffusion coefficient of the membrane (or liquid layer) should be less than 6.9 x 10 -9 m 2 / s., Preferably less than 6.9 x 10 -10 m 2 / s., and with the most preference, less than 6.9 x 10 -11 m 2 / s.
    Examples of materials that are suitable for use as the barrier membrane layer of the present invention include those materials that are used conventionally as a release layer in flexographic printing elements, such as polyamides, polyvinyl alcohol, hydroxyalkyl cellulose, copolymers of ethylene and acetate
    Petition 870190088499, of 08/09/2019, p. 17/22
    9/10 vinyl, amphoteric interpolymers, cellulose acetate butyrate, alkyl cellulose, butrial, cyclic rubbers, and combinations of one or more of those mentioned above. In addition, films such as polypropylene, polyethylene, polyvinyl chloride, polyester and similar transparent films can also serve as barrier films. In a preferred embodiment, the barrier membrane layer comprises a polypropylene film or a polyethylene terafthalate film. A particularly preferred barrier membrane consists of a Fuji® Final Proof membrane available from Fuji Films.
    The barrier membrane should be as thin as possible, consistent with the structural requirements for handling the film and the photopolymer film / plate combination. Barrier membrane thicknesses between about 1 and 100 microns are preferred, with thickness between about 1 and about 5 microns being most preferred.
    The barrier membrane must have sufficient optical transparency such that the membrane does not harmfully deflect or deflect the actinic radiation used to expose the blank photosensitive print element. As such, it is preferred that the barrier membrane has an optical transparency of at least 50%, most preferably at least 75%.
    The barrier membrane needs to be sufficiently impervious to oxygen diffusion, so that it can effectively limit the diffusion of oxygen in the photocurable layer during exposure to actinic radiation. The inventors have determined in the present document that the barrier membrane materials noted above at the thicknesses noted above will substantially limit the diffusion of oxygen in the photocurable layer, when used as described herein.
    In addition to limiting the diffusion of oxygen into the photocurable layer, the barrier membrane can be used to impart or apply a desired texture to the printing surfaces of the printing element or to control the surface roughness of the printing surfaces of the printing element a desired level. In one embodiment of the present invention, the barrier membrane comprises a matte finish and the texture of the matte finish can be transferred to the surface of the plate to provide a desired surface roughness on the surface of the printing plate. For example, in one embodiment, the matte finish provides an average surface roughness that is between about 700 and about 800 nm. In this case, the barrier membrane comprises a polypropylene film with a cured photopolymer layer on it and the cured photopolymer layer has a defined topographic pattern on it. The texture or roughness of the surface barrier membrane will be printed on the surface of the photopolymer layer (photocurable) during the lamination step. In general, surface roughness in this respect can be measured using a Veeco Optical profilometer, model Wyko NT 3300 (Veeco Instruments, Plainville, NY).
    Petition 870190088499, of 9/8/2019, p. 18/22
    10/10
    In another embodiment of the present invention, the barrier membrane comprises a smooth nanotechnology film with a roughness of less than 100 nm. In this embodiment, the average surface roughness of the printing plate can be controlled to less than about 100 nm.
    The barrier layer can be laminated to the surface of the printing plate using pressure and / or heat in a typical lamination process.
    In another embodiment, the printing plate can be covered with a layer of liquid, preferably a layer of oil, prior to the exposure step, and the oil can be transparent or dyed. The liquid or oil serves here as another form of a barrier membrane. As with the solid barrier membrane, it is important that the liquid used is optically transparent to the actinic radiation used to expose the photocurable layer. The optical transparency of the liquid layer is preferably at least 50%, with the most preference at least 75%. The liquid layer must also be able to substantially inhibit oxygen diffusion in the photocurable layer with an oxygen diffusion coefficient as noted above. The liquid must also be viscous enough to remain in place during processing. The inventors have determined in this document that a layer of liquid from 1pm to 100um in thickness, comprising any of the following oils, will meet the criteria mentioned above: naphthenic or paraffinic hydrocarbon oils, silicone oils and base oils of vegetable. The liquid should be spread over the surface of the print element after the in situ mask is created, but before the blank print element is exposed to actinic radiation.
    After the blank photosensitive print element is exposed to actinic radiation, as described in this document, the blank print element is developed to display the embossed image on it. The development can be completed by several methods, which include water development, solvent development and thermal development, by way of example and not as a limitation.
    Finally, the embossed image printing element is mounted on a printing press cylinder and printing is started.
