    Reproduction method for producing multi-colour printings wherein the colour is obtained by a plurality of coloured surface elements. The surface of the image is cut out into partial surfaces having the same glare and each partial surface is in turn cut out in surface elements adjacent to each other forming a coloured portion and an achromatic portion which enable to determine which colour tone of the corresponding image portion has to be produced. The surface elements forming the coloured portion are printed with a maximum of two colours out of the six printing colours and the surface elements forming the achromatic portion are proportionally comprised of black and white.

    The invention relates to a method for producing multi-color prints, in which color is created using a variety of colored flat elements.
    The purpose of the invention is to expand the possibilities of reproducing flowers on multicolor prints.

W1OSK. OST according to the example in FIG. 4 a (c); 5 is an example of another color & nuance. (a), a representation of the output of percentage color surfaces according to the example in FIG. 5a (b) a bitmap image of the percentage color surfaces in a partial plane according to the example on; figa, (c); Fig. 6 illustrates the division of the image surface into flat elements and partial planes for separate 1st separations; Fig. 7 shows a device for implementing the method (a is an example of recording a flat element using a universal device) {. Fig. 8 is an example of a scheme for determining the color components of individual partial planes (a is a truth table).
    The method is carried out as follows.
    Work with seven or eight
    printing inks and printing elements lie next to each other, with the plane of the printed multi-color image being decomposed into geometric partial planes of equal sizes, for example, squares, rectangles, equilateral triangles, hexagons or

    diamonds, and the dimensions of the individual partial planes are chosen so that they, under conforming consideration, lie below the resolution threshold of the human eye, so that the partial planes cannot be distinguished separately. If the print is made on white or transparent material, then work with seven printing inks, namely: yellow (absorption spectrum yn), orange-red (absorption spectrum of Cases 380-590 nm), purple-crab (spectrum absorption of PC 470-590 nm), violet-blue (absorption spectrum (rg 480-700 nm), cyano-blue (absorption spectrum and cg ≈ 540-700 nm), green G absorption spectrum / (5 380-486 nm and 550-700 nm)) and black, if the printed material is transparent, then the color is printed with white paint.
    Separate partial planes are filled with a maximum of four flat elements disposed adjacent to each other, at. By this, a color component of a color show is produced by two of the six colored colors that are associated with it. Sulfur is a component of the color nuance that is always formed by means of white and white colors.
    In the case of applying the method on white or transparent printed matter, it is possible to work with both transparent and opaque (red) inks. When printing on colored printing material, they mainly work with coating paints.
    Based on its three types of visual cells (cones) sensitive to different light wavelengths, the human organ of the eye can perceive three primary ones; violet-blue, green and orange-red, and with its own sticks it can perceive different values of brightness. The three components of the original colors correspond to the eight primary colors (Fig. D).
    The primary colors are yellow (Y), purple-red (M), cyan-cyan (C), violet-blue (V), green (G), orange-red (O), gray primary colors — white (W ) .. and black (S). In the table in figure 1, crosses and dashes indicate which of the three colors
    purple-blue, green and orange-red are present in the respective primary colors.
    Figure 2 shows the individual features of the YC combinations; CG; CV; MV; MO and YO, which show that the color types come from two primary colors, and the gray types from white and black.
    FIG. 3 shows how color sensitivity can be represented by components, with an index system for three
    the component is introduced in such a way that the maximum reproduced in FIG. 60 is set to the sensitivity value equal to 100%, and the minimum value is 0%. The combination of the three components, i.e. corresponding part
    her quantity of the corresponding color. .. 20 to the examples, depicted ki, gives the resulting color. 40 and 56. Color impression, nuance F. From this it is seen that there are components of white and black. The box in the upper right represents bleached clean paint (spray paint), and the field in the lower right represents the color, which consists of a gray component and a color component.
    Figures. And a show, as in the case of this example, create separate color separations to the colors white, whole, green and black, and you can easily see that the joint print again provides a pattern.
    In order to explain how individual quantities of partial paints are determined, one should again and again. color show F4 (fig.4a)
    determined by V 99,
    There are so many nuances of color as there are quantitative possibilities for the variation of primary colors.
    On figa shows the implementation of the color nuance F4, which consists of the following short-circuit component,%: V 99, G 80, O 45,
    Fig. 5a shows the implementation of the color nuance Fj, which consists of the following components,%: V 15, G 75, O 55.
    As can be seen from the above, in this way all possible color nuances can be obtained.
    This principle of integral mixing is useful for understanding the printing technique according to the invention.
    The proposed printing method is explained in more detail with the aid of Fig. 6, which shows a reproduction area that is formed from a large number of flat elements (Fig. 2b), 45 which, according to the principle of integrated color mixing, are filled with individual partial planes of eight primary colors . In the case of fields in the left column and in the case of the upper floor in the middle column, these are primary colors: white, yellow green and black; in the case of a flat element in the middle, these are superimposed printing of two primary colors — yellow and green, and the case of a flat element in the middle at the bottom is a gray flat element,

    In order to explain how individual quantities of partial paints are determined by the film, one should again repeat the examples shown in figures 40 and 56. The impression of color,

    80 and about 45%. On Fig shown,
    How are the individual quantities of the primary colors partial colors determined For all three of the original colors in this example, there is a common factor of 45, which represents the white component. This follows from a comparison with the table (Fig. 1), in which the first line shows all the original colors V, G and O, For the remaining colors. oh sharpening
    the colors V and G are the total number of colors equal to 34%, and it follows from the table in FIG. J that there is a common primary color — a cyan-goal battle. Cyan-blue color, so
    in the case of this color nuance, 35% is represented (FIG. 46); In this case, 19% remains for one violet-blue, and 1% for black, which can be neglected
    For the example shown on the game, the total white number is 15%. Green and Orange
    Red flowers have an amount of color equal to 40%, which, according to the table in FIG. 1, gives a general base yellow color. After deducting 40% of the yellow color for green, there is still
    with the amount of paint equal to 20%, and the remainder of the black paint equal to 25%. A color nuance is obtained (FIG. 3b), which corresponds approximately to the plane depicted in FIG.
    FIG. 7 shows a device for recording separations as shown in FIG.
    The light beam in the example of Fig. 7, through the device for splitting the beam, which consists of a system of mirrors, is divided into six partial rays and the partial rays through modulators, which are individually controlled through an electronic control circuit, are fed to a recording medium. The output signals of the modulators are directed through the optical cable and the optics to the recording medium, in the present case, to the film, which is tight on the rotating drum. Depending on the time at which the modulators are turned on, a sample of the exposure is obtained, such as shown schematically on a film. Figa shows the structure of the part-; planes. If we consider the color separations of FIG. 6 (Y-y and if, for example, color separation 6 would be written (G, then the modulators are connected to the places where there is a corresponding white printing ink.
    The registration of these partial planes can also occur by direct ink application, such as, for example, by means of a color-differentiating inkjet print head, for which, with appropriate control, inkjet printing devices can be used.
    Based on the scheme shown in Fig. 8, for obtaining separations for the method according to the invention, a normal color matching device is located, which through a three-color reading from the original by means of optoelectric conversion prepares the color components - violet-blue, green and orange-red. Such matching devices are known, as well as an integral part at the beginning of the named color scanner, so that the reading unit is not described. It originates from three-color color signals obtained by means of a photoconverter.
    The color components of violet-blue, green, and orange-red are fed to analog-to-digital converters 1 to 3, to the output of which the minimum selection step 4 is connected.
    507626
    foot values. This stage at its output gives the smallest of the three color components, which is then
    g in subtractors 5-7, which are connected to an analog-to-digital converter, and to the output of the minimum stage, is subtracted from the individual color components.
    10 The smallest signal that appears at the output of the minimum stage,. represents the percentage of white color component that is common to all three components and through,
    15, line 8 is written to the separations buffer. The information entered there corresponds to the percentage value of white in the corresponding image location, in which the color components V, G and O were obtained from the reader 20.
    The outputs of the subtractors 5-7 are brought to the limiting stages 9-11, in which the output signal},
    25, if they are greater than or equal to 1, are limited to 1, and if they are less than 1 or O, all are interpreted using 0. These signals V, G and O are given at the beginning of the table drive.
    30–12, for which a truth table is given in FIG. 1, which corresponds to the assignment of the original colors of the main color to the primary colors in FIG. Instead of dashes in figure 1 were
    35, O is set, and the crosses are binary 1. At the output of the tabular drive, then the initial combination V, G, 0, one of the 40 primary colors Y, M, C, V, G or 0. Through this process, it is identified which of the six primary colors is contained in the corresponding place of the image, which is visible from
    45 of the matching device. / In the example shown in figure 4, this would be the main color of cyan-blue, and in the example shown in FIG., The main color is yellow,
    50 To the output of the subtractors 5-7, a stage 13 is connected, which of the three difference signals searches for the middle signal. Since by means of the first difference formation one of the signals.
    55 occurring on steps 4 through 7, equal to O, then the average signal in OC 7 is the smallest of the two remaining signals, so that step 13 is designed as a simple step for
    detect a smaller signal. This signal constitutes the percentage of the motley base color appearing at the output of the tabular storage unit 12, in the example of FIG. 4d, for cyan color is 35%, and in the example of figure, 3B for yellow is 40%.
    Further, additional subtractors 14–16 are provided at the output of the subtractors 5–7, in which the average difference signal supplied from stage 13 is subtracted from the difference signals emanating from the stages of the subtractors 5–7. additional restrictive steps 17 -} 9, for which the same condition is really the same as for restrictive steps 9 - AND, namely, that all signals,. which are 1, are interpreted as. 1, and that all signals that are less than 1 are interpreted as 0. These signals are again fed to the tabular storage 20, which contains the same tables as the tabular storage 12. The output of this tabular storage appears again in accordance with the table 8a, the signal of the primary color, in the case of FIG. 4, a violet is signaled, and in the case of fig. The outputs of the subtractors 14-16 are connected to the step of selecting the maximum value, which indicates the percentage color component of the primary color, according to the output of the accumulator 20, which is, according to fig.4o or b, 19% for violet colors, and according to figs 5i or o, the value is 20% for green.
    Separation should be set for each gray and each of the color of the six colors, since for each of these color separations storage units are provided, which in Fig. 8 are indicated by abbreviations for the corresponding colors. Separation signals of six color printing inks. Are then brought through a switch to the corresponding accumulators and separations. The outputs of the average value circuit 13 and the maximum value circuit 21 for the six switches are connected to six color separation accumulators for six variegated primary colors. The activation of the switches takes place
    507628
    Dit through the output signals of tabular drives 12 and 20, i.e. when, in the case of accumulator 12, a color appears at the output, then the corresponding percentage value of this color is brought to the corresponding separations memory through a switch. For this to the exit of the step
    10, 13 six switches Y, M, C, V, G and O are connected, which are connected with the corresponding lines Y, M, C, V, G and O of the output signal of the table storage device 12. The output of the stage 21 is max 15 ma and the signal wires of the table drive 20 is also connected through six such switches, which have the same designation, and the outputs, respectively, of two identical
    20 switches are connected in series to the input of the corresponding separations storage device. To determine the black prodant, add a percentage of the white value
    25 average value and maximum value, and subtracted from 100%. This occurs in stage 22, which is connected to the output of the minimum stage, the average value stage and the maximum stage. The output of this stage is then sent to the separations storage for black.
    For the read point of the image,
    35 which may have Y, G values
    and O, thus a maximum of four color values are determined, namely white (1st, one of the six color primary colors in the tabular storage
    40 le 12, one of the six color primary colors in the tabular storage 20 and the color value for black. However, it is possible, as described -... at the beginning, that the individual
    45 of these values are O, or they can be any value between O and 100%. The conversion of these values contained in the separations signals can be carried out by a known device, in which individual percentages for the individual percentages are flat elements, as they are, for example; in the examples of Fig. (depicted for separate separations of the places of the image
    55 wives. Color separation stores
    (FIG. 8) provide, for example, input signals for an address register of known construction, with the values of the ground elements related to
    9 1450762 to separate percentages before reproduction, are entered into the accumulator, j also of known construction. According to the invention, each individual color separation is obtained by means of a laser recording device: the color separation storage devices (FIG. 8) are connected one after another to the address register and control the laser recording device (7) from the connected storage device (FIG. 7) Fig.8) give from O to 100%; by means of which, in appropriate places of the image, the corresponding flat elements or partial planes are recorded. Printing occurs in such a case. The color separations are transferred one after the other in different color values to the printing material 20. As can be seen from fig.ba, individual partial planes can be filled with either one of eight colors, or, when it comes to
