Definitions
- the invention relates to a multicolor printing method for textile substrates according to the preamble of independent claim 1, in particular to a multicolor screen printing method according to the preamble of independent claim 2 and a multicolor inkjet printing method according to the preamble of independent claim 11.
- the screen printing process is usually used, in which a separate screen printing stencil is required for each printing ink involved in the printing process.
- Screen printing stencils can either be fully transparent or, in order to achieve halftones, can also be rasterized analogously to the halftone printing plates in offset printing; in the latter case we are talking about screen printing stencils.
- the raster percentage value of a raster screen printing stencil is also understood to mean, again in analogy to offset printing, the ratio of the permeable area portion to the total area of an imaginary elementary area of the raster screen printing stencil.
- the entire motif to be printed is constructed from a limited set of generally four standardized printing colors (mostly cyan, yellow and magenta and black). The case of special colors is irrelevant for the following and is therefore not considered.
- the print template containing the motif to be printed is photoelectrically measured pixel by pixel using a lithographic scanning device, and so-called color separations are created from the measurement data obtained (today electronically using digital image processing), which represent the proportions of the four standard printing inks on the motif. These color separations are then used to produce raster films which are used to produce the individual printing plates for the four printing inks involved.
- the print template or the motif to be printed on it is broken down into individual areas, each of which is assigned a single printing color that comes as close as possible to the actual color tone.
- a screen printing template is then created for each of the intended printing inks, which is permeable in all areas of the motif belonging to the printing ink concerned.
- the creation of screen printing stencils today also takes place with photoelectric image scanning devices (lithographic scanners) and is supported by digital image processing with analog devices such as in the production of offset printing plates.
- the present invention is intended to overcome these difficulties and limitations when printing on textile substrates and to improve a method of the generic type defined in the preamble of the independent claim in such a way that a substantial improvement in the reproduction quality and increased brilliance of the printed color tones can be achieved on conventional screen printing systems and that special effects such as shading, finely graded color gradients, 3D effects etc. can be realized without significant additional effort.
- Another object of the invention is to achieve these advantages in other printing processes for textile substrates, for example an inkjet halftone printing process.
- a template 1 contains the motif to be printed, here for example in the form of a sailing boat with the sun.
- a (raster) screen printing stencil 2 is produced from this printing template 1 for each of the printing inks to be used in printing.
- These stencils 2 are then fed to a multi-color screen printing system 3, in which the textile substrate 4, for example, is printed with the individual printing inks in accordance with the stencils 2.
- the substrate which is produced as a result of this process and is printed with the motif of the original 1 is designated by 9. So far, the method according to the invention completely agrees with conventional methods, so that no further explanation is necessary in this regard.
- FIG. 2 schematically shows the steps typical for the production of the screen printing stencils 2, as they result when using a computer-controlled lithographic raster film exposure system 5 which is customary today.
- the exposure system 5 typically essentially comprises a photoelectric scanning system 51 and an exposure system 52 as well as a control computer 53 which controls these two systems and establishes the connection to the operator with the usual input and display units 54 and 55 for interactive communication with the operator.
- a typical well-known raster film exposure system of this type that is used in lithographic companies worldwide, is distributed for example by the company Scitex.
- the following explanations relate to this known system for reasons of simplicity of understanding.
- the method according to the invention is in no way restricted to the use of this special system and to the use of a raster film exposure system at all.
- the scanning system 51 reads the motif of the artwork 1 into the system 5.
- the artwork or the motif picture element is measured photoelectrically (scanned), usually either in standardized color channels (typically red, green, blue and visual or infrared corresponding to the standard printing colors cyan, magenta, yellow and neutral black) or in a number of more or less narrow spectral ranges.
- the entirety of the measurement data generated thereby represents the motif in electronically stored form.
- the computer 53 uses the usual methods of electronic image processing either fully automatically or interactively with the operator (in electronic form) to produce color separations 56, which are the proportions of the individual reproduce the inks used in printing on the overall motif.
- the color separations 56 can be displayed on the screen 54, with the operator being able to make corrections per image element via the input unit 55 (keyboard, mouse, graphics tablet, etc.).
- raster films 58 are now generated in the exposure system 52 for each of the printing inks involved in the printing.
- the control computer 53 calculates, for each of the printing inks involved, the required halftone percentage value R i of the halftone film for each individual picture element of the motif and from this the required exposure data for the relevant picture element of the halftone film on the basis of standardized or e.g. Parameter inputs defined printing conditions.
- the totality of the raster percentage values R i which are decisive for the exposure of the raster films 58, is symbolized in FIG. 2 by raster extracts 57 (naturally only available as data).
- the operator can also interactively influence this step, for example by making corrections or at all can enter the raster percentage values R i for individual or all picture elements.
- the method according to the invention makes use of precisely this possibility.
- the screen printing templates 2 for the individual printing inks involved in the printing are now produced from the raster films 58 using known standardized methods. This is absolutely conventional, for example like that of Scheweiz. Seidengazefabrik AG, CH-9425 Thal published company publication "SST - a handbook for the screen printer", and therefore requires no further explanation.
- the screen printing stencils can of course also be produced using the classic (e.g. photographic) methods of lithography through the usual manipulations of the films.
- a set of calibration prints hereinafter referred to as a color atlas
- the color atlas A comprises a number of color tables T which is dependent on the number of printing inks from a limited set of printing inks selected according to criteria to be explained below. These, as shown in FIG. 3, each consist of a square arrangement of a plurality, for example of individual color fields F. Each color field F within a color table T represents the superimposition of a maximum of three printing inks always the same for the same color table with different proportions of the three colors.
- the proportion of one of the three colors is constant within a color table (0-100% ), the proportions of the other two colors vary gradually between 0 and 100%.
- a number of color tables corresponding to the number of desired gradations is therefore required to display all combinations of the superimposed prints of three printing inks.
- two types of screen printing stencils are produced by any known method.
- One type has constant raster percentage values of different gradations over its entire area.
- the other type contains strip-shaped zones that are more constant, but one below the other differently graded raster percentage values. It is obvious that with these two types of screen printing stencils, all color plates T of the color atlas A can be printed.
- the gradations of the halftone percentage values of the screen printing stencils are advantageously chosen such that the printed color fields F result in an essentially linear graded tone value progression of the individual colors.
- the selection of the ink triples from the available limited set of printing inks is preferably made according to the e.g.
- the criteria described in EP-A-0 446 168 are such that the individual subspaces covered by the overprinting of the three printing inks of the respective printing ink triplet of the printable color space that can be represented with all printing inks at all do not overlap, as is illustrated in FIG representative cut through a typical color space, such as in said EP-A-0 446 168.
- the entire color space is designated by FR, the sub-spaces which are essentially triangular in section bear the designations TR1-TR5.
- the points P1-P6 represent in the sectional plane shown the color location of a single one of a total of six printing inks. More details can be found in the aforementioned EP-A-0 446 168.
- the color fields F of the color atlas A printed according to the above thus represent the entire color space that can be produced with the selected set of printing inks in discrete gradations.
- Each color field F represents a defined color location (color impression) within the color space, and for each color field F these are among the on the basis of the printing conditions used to achieve the color impression in question, the raster percentage values R i required in the associated raster screen printing stencils for the respective three printing inks are known.
- the assignments of in this way determined for the underlying printing conditions and the selected substrate Color impressions (color locations) and halftone percentages of the screen printing stencils are now used in the process according to the invention for the production of the halftone screen printing stencils required for printing the motif.
- Image element is understood to mean a more or less large area of the artwork, preferably a punctiform area.
- the size of the (punctiform) area depends on the resolution of the lithographic scanning film exposure system used.
- the color impression is determined visually for each image element of the artwork 1 and the color field F closest to this color impression is determined in the color atlas A.
- the data associated with this color field about the maximum of three printing inks involved and the associated halftone percent values are then input via the input device 55 into the control computer 53 of the halftone film exposure system 5, the image elements are "formulated".
- the raster film exposure system 5 When the data for all the picture elements of the printing original have been entered in this way, the raster film exposure system 5 generates the raster films 58 for the individual printing inks on the basis of the entered raster percentage values. The screen printing templates 2 for printing the motif are then produced from this in the manner already explained.
- FIG. 5 shows the schematic sequence of an expansion of the method according to the invention.
- the color impressions of the individual fields F of the color atlas A are measured using a color measuring device 6 and the color value data determined for each color field in association with the associated data about the printing inks involved and the respective raster percentage values R i for these printing colors in a preferably electronic one Storage 7 filed.
- the coordinates of a color coordinate system such as the L, a, b or the L, u, v system according to the CIE (Commission Internationale de l'Eclairage) are particularly suitable as color value data.
- the color impressions (color locations) of the individual picture elements of the original 1 are also recorded as color value data by means of a color measuring device 7.
- the color value data of the individual picture elements of the print template are then (manually or automatically) fed to a comparator 8, which is connected to the memory 7 and reads the corresponding raster percentage values R i from the memory 7 for each picture element of the print template based on the color value data supplied to it.
- These halftone percentages are then fed back either manually or preferably automatically to the halftone film exposure system the corresponding raster films are generated from it.
- a device to be positioned by hand on the individual picture elements of the printing original 1 or on the individual color fields F of the color atlas A or preferably a scanning device which performs the positioning and measurement automatically can be used as the color measuring device 6.
- the scanning system 51 contained in the raster film exposure system 5 itself can be used for this purpose.
- the memory 7 and the comparator 8 can also be implemented by the control computer 53 of the raster film exposure system 5.
- other implementations of the method according to the invention are also possible.
- the method according to the invention is in no way limited to the screen printing technique explained above, for example, but can generally be used in other, in particular picture element-oriented printing techniques, in particular, for example, also in connection with so-called inkjet printing systems.
- ink jet printers have a number of fine nozzles corresponding to the number of printing inks to be used (“printing inks”), from which the printing inks are sprayed onto the substrate in the form of fine droplets.
- the color impression of a picture element of the substrate results from the absolute and relative proportions of the printing inks sprayed onto the substrate in the area of this picture element, these proportions, which can be defined, for example, as the number of unit droplets (e.g. 0-16 droplets) by corresponding ones electrical control of the nozzles can be determined.
- the control of the nozzles is computer-aided on the basis of a print data table, which for each picture element of the print template to be printed contains the proportions of the individual printing inks required under the given printing conditions for the technical reproduction of the same.
- This print data table thus corresponds to the totality of the screen percentage values of a print template in the example of the screen printing method explained above, since these screen percentage values or the screen screen printing stencils based on them ultimately do nothing other than control the amounts of the printing inks involved and thus a measure of the Show proportions of the printing inks involved. Because of this direct correspondence between halftone percentage values and proportions, the principles of the method according to the invention explained above on the basis of the halftone screen printing method can be transferred very simply to the inkjet method.
- both the motif to be reproduced and the color atlas are simply replaced by the print data table or the proportions of the individual inks it contains.
- the actual printing process ie the creation of the The print data table following the steps (the printing of the substrate using an inkjet system based on the print data table mentioned) is just as standardized as the production of the screen printing stencils based on the screen percentage values and the printing in the screen printing system itself.
- the image areas of the print template do not become too much for reasons of practicality Choose small; in particular, pixels of the same color will be combined into larger areas.
- Another option is to select only a few characteristic image areas that are particularly relevant or critical for the color impression from the entire print template and to take the corrective measures, i.e. the determination of the required halftone percentage values or quantitative proportions of the printing inks involved using the color atlas only for these areas. The remaining areas can then be corrected or treated accordingly, for example roughly analogously to the tone value curve in the color atlas. Numerous procedures are possible here, and the person skilled in the art requires no further explanation in this regard.
- the method according to the invention overcomes the limitations of conventional methods when printing on textile substrates.
- this makes it possible to print each image element of the motif with the optimal combination of printing inks, thus enabling special effects and the printing of critical color tones that were previously difficult to achieve and, on the other hand, a brilliance of never before achieved with a relatively small total number of printing inks To achieve color impressions.
