Definitions
- the invention relates to a method according to the preamble of claim 1 and an apparatus for performing a such procedure.
- the "printing" parts of a motif lie level lower than the surface of the impression cylinder.
- the preferred by engraving, lasering or by etching printed images introduced into the cylinder surface filled with a low viscosity paint and the Excess amount of ink with a doctor knife from the Cylinder surface scraped off.
- the color transfer to the Printing material is made by pression. This will be a softer one Impression cylinder, the impression cylinder, against the impression cylinder hazards.
- the substrate Located between the impression cylinder and the impression roller the substrate. With this printing technique it is necessary to color the entire impression cylinder, even if is only partially printed.
- the printing areas are located well above the level of the non-printing lots, e.g. B. between approx. 0.550 mm and 3.0 mm.
- the material is flexible from which the printing blocks are made, as a rule between 40 ° Shore A and 90 ° Shore A and preferably from Rubber or the like.
- a laser made of rubber or a similar material burned out.
- Area or laser exposure were applied to the polymeric material factory-supplied photoinitiators. Under the influence of a certain length of UV light react during exposure the photoinitiators at the places on the plate where the Light penetrates the uncovered areas of the negative.
- the Picture elements raised on the plate, which was later colored and put the ink under pressure on the printing block.
- the printing form itself consists of either Individual clichés that are glued to a cylinder or made of sleeves that are coated endlessly or seamlessly or cylinders.
- these areas raised in the printing block are usually inked using an anilox roller.
- This is a cylinder, in the surface of which small cups are introduced in a homogeneous order, preferably struck in copper with a diamond or burned by means of a laser into a ceramic layer applied to the cylinder.
- the number of cups per cm 2 vary, in the current state of the art between approx. 3600 and 250,000, on average by approx. 50,000.
- the opening area of a cup must be smaller than the printing surface of the smallest raster point so that it comes into contact with the Anilox roller does not penetrate into the bowl during the coloring process and also colors its flanks.
- Coloring has the result that the color building up on the edge hardens, the point widens in an uncontrolled manner, thereby absorbing and releasing more color in an uncontrolled manner and thereby negatively changing the printed image.
- This is due to the fact that there are serious disadvantages compared to the other two printing methods when it comes to the representation of fine drawings in the lighter areas of a motif as well as color mixed tones in scale printing, for which fine screen percentages are required.
- the cliché grid point in the 54 L / cm grid is finer than 1% area coverage but cannot be printed because on the one hand the opening area of the bowl of a 220 L / cm anilox roller is approx. 400% larger and on the other hand the relatively rough one Ceramic layer of the anilox roller grinds the flexible, small point after a short run time.
- the result is that the minimally printable area coverage of a fine-line grid point must be increased, e.g. B. must be drastically reduced to 4% to 5% or the number of lines, z. B. to about 32 L / cm.
- the well geometry determines the scooping volume of the respective anilox roller and thus the ink layer thickness that can be transferred to the cliché.
- the roller is in the entire width and in the entire circumference colored the excess color either over a Squeezed rubber roller or preferably with a squeegee stripped.
- the entire roller in the working width and in Color the scope 100%, even if only partially 5% of the Roller surface required for inking the cliché becomes.
- the solvents of the z. B. 95% unused area permanently evaporate and pollute the environment Loss must be added back to the color permanently, what moreover causes extreme costs.
- the of the Anilox roller transferable ink layer is through that Scoop volume specified. For example, through change of the substrate a larger ink layer thickness required, this can only be done by changing the anilox roller be achieved in a corresponding volume.
- anilox rollers different volumes required, which besides one higher investment also higher roll replacement costs has the consequence.
- anilox roller it is imperative that anilox roller to be exchanged, the doctor blade etc. with larger ones Shares of solvent to wash, which in addition to costs a not inconsiderable environmental impact evaporating solvents.
- the current coloring system provides that the Anilox roller turns counter to the printing cylinder. This causes the anilox roller to run after inking and knife coating Approximately half of the circumferential length is free before contacting it the cliché for color delivery. The cliché is running again half a circumferential length free before the color by pressing on the impression cylinder overlying printing material is released.
- the Solvent content in the paint should be so high that with one half anilox circumference and a whole Printing forme cylinder turn the color neither on the Dry the anilox roller surface on the cliché can. After squeegee, while staying on the Anilox roller and the cliché, the solvent evaporates, it this creates not only costs but also relatively high ones Environmental pollution. Because the surface tensions of the Anilox roller, the color and the plate are relatively the same, can transfer from the anilox roller to the printing block primarily done by pression.
- the printing and non-printing lots in one plane.
- the pressure plate is created so that the printing lots preferably with a greasy color and the non-printing areas be moistened with water so that the greasy color of is repelled from the damp areas of the pressure plate.
- the paste-like color is used in a "long” inking unit one technically, in terms of production and handling very complex roller grinding system on one transferable color film thickness reduced and under Transfer the compressive stress to the plate using rubber rollers.
- the so-called “short” inking unit sets a ratio more viscous color and controls the color film over the Scooping volume of an anilox roller.
- the color film changes permanent for the duration of the whole Transfer process. Fluctuations within the Mixing ratio between solvent and solid contents cause color changes in the printed image and affect the expression behavior. Beyond that it is State of the art that over the working width of the machine and in the entire development length of the ink rollers, the Color must be provided, even if only partially is removed, e.g. on one to the anilox circumference seen 5% place. With solvent paints the majority evaporates in the transmission system and only a small proportion on the substrate, e.g. B. too 95% if only 5% of the area has been removed becomes. This results in a high cost burden and a extreme environmental pollution.
- the invention has for its object a method of type mentioned and a device for carrying out to create this process and thereby a larger one Cost-effectiveness, especially by saving color and achieve lower environmental impact.
- Claims 6 to 8 are for a device for Implementation of the method according to the invention.
- the method according to the invention becomes a printing method created in which extremely polarizing differences in the surfaces of the color-bearing (printing) and the the color non-supporting sections are present.
- the sections that should not take up color with a inorganic polycondensate and / or one Water repellent for surface treatment which contains as an effective component a silane in which a at least partially fluorinated organic group via a saturated residue is bound to the silicon, and / or self - crosslinking aqueous preparations from Resins containing perfluoroalkyl groups coated, the or which is / are suitable to repel color and none Allow liability, in contrast to the level similarly lying surfaces of the color and the means of modular spray technology adopting paint mist Layers.
- the surface tension is not printing sections reduced so that the through Spray applied paint not accepted here or is repelled.
- DE-A1 195 44 763 Inorganic polycondensates that prove to be special have advantageously shown are in DE-A1 195 44 763. These are polycondensates, which also have the desired flexibility.
- the said DE-A-1 195 44 763 is directed to polycondensates on the Basis of one or more for hydrolytic Polycondensation enabled compounds of the elements M of the Main groups III to V and subgroups II to IV of Periodic table of the elements, being in these polycondensates to at least some of the central atoms M each at least one organic group G which has at least 2 has aliphatic carbon atoms to each at least one fluorine atom is bound, either directly via one of the carbon atoms or via a connecting group A is bound.
- Such water repellents for surface treatment are in the WO / 14958 from Siemens AG has been described.
- at least one substitutable leaving group can Silane still carry further alkyl residues. That for different surfaces suitable Hydrophobing agent becomes liquid or gaseous Phase applied to the surfaces to be treated and also creates a long-lasting repulsion effect organic solvents.
- the invention provides that Surface tension of the non-printing parts of the Printing block through the coating with a flexible, inorganic polycondensate and / or one Water repellent for surface treatment, which contains as an effective component a silane in which a at least partially fluorinated organic group via a saturated residue is bound to the silicon, and / or self - crosslinking aqueous preparations from Low-strength perfluoroalkyl group-containing resins, preferably by 0.6 ⁇ m, drastically, preferably by> 30%, see above to change that color adhesion to the coated Sharing is excluded.
- the invention provides a modular, speed-independent spray technology, preferably in the working width, which is absolutely absent through a paint mist closed color film on the color-bearing picture elements of the printing block.
- the number of to be used Module is variable.
- the modules themselves are individual controllable. Only the modules give color in their Sectors of picture elements are to be colored.
- the direction of development controls sensors the spray duration.
- the Color intensity is regulated with computer support. Around homogeneous to ensure a color film on the printing block the drop size is preferably ⁇ 20 ⁇ m.
- the anilox roller for flexographic printing in this invention does not apply, the dependency of the printable is also eliminated Cliché dot size to the opening area of the grid bowl, it smallest elements of ⁇ 1% area coverage are to be colored. As the anilox roller for flexographic printing in this invention no longer depends on the necessary Size of the grid point for damage by the Abrasion on contact with the ceramic layer of the anilox roller to avoid it is any point size without damage to colorize.
- anilox roller for flexographic printing in this invention does not apply due to tolerances in size the different shape and volume of the cup shape which is inhomogeneous due to the webs of the well limitation Color film, because in this invention the coloring over a Spray technology that produces paint mist is the Color application on the surface of the printing block itself completely homogeneous.
- the printing block sprayed directly the height of the color film can be reduced by 50% because the solvent content is reduced by approx. 90% or completely eliminated when using solid colors.
- roller mill is part of the long inking unit of the offset dispenses with this invention, the manufacturing and drastically fixed costs.
- this Invention far cheaper and simpler Color systems can be used with less environmental impact.
- This invention enables the solvent content in gravure printing be drastically reduced, preferably by approximately 80%, especially if the squeegee system is maintained and the lower picture elements are coated. Through the lower surface tension is almost complete Emptying the cells ensured.
- the invention provides for the coated parts low surface tension after spraying before that color resting thereon but not adhered to by pressure and Remove the suction and return to the paint cycle bring in.
- the invention provides for the coating in flexo that after exposing the picture elements, preferably from the black burn-out or and and light-sensitive layer of the printing block, these places after exposure Application of a substance that can be detached later covered become. After lowering the non-printing portions the coating is applied to it and then the Substance removed from the parts to be printed later.
- the invention provides for the coating in offset that after exposing the picture elements, preferably from the black burn-out or and and light-sensitive layer of the printing block, these places after exposure Application of a substance that can be detached later covered become. After the non-printing portions are exposed the coating is applied to these places and afterwards the substance is removed from the later printing parts.
- the invention provides for the coating in gravure printing Use highly diluted solvent paints before that after Expose the picture elements, preferably from the black Burn-out or and and light-sensitive layer of Printing blocks, these places by applying a later removable substance to be covered. After this The lower of the non-printing portions will Coating applied to it and then the substance of the parts to be printed later.
- Fig. 2 shows in principle the operation after method according to the invention.
- the anilox roller is missing.
- the cliché roller is like that pretreated that the non-printing sections with flexible inorganic polycondensate and / or one Water repellent for surface treatment, which contains as an effective component a silane in which a at least partially fluorinated organic group via a saturated residue is bound to the silicon, and / or self - crosslinking aqueous preparations from Resins containing perfluoroalkyl groups are thus coated that the surface tension of these sections was significantly reduced.
- the paint is applied immediately before entering the pressure gap between Plate cylinder 1 and impression cylinder 2 with the help of a Spraying device, which in addition to different across Unwinding direction arranged spray modules 4 also one Has suction device. This suction device sucks if necessary on the non-printing coated Sections of existing paint mist and leads this color back to the color cycle.
- Spray modules 4 are individually controllable to only there spray where color is actually in the direction of development is required. So there is less color from the start not sprayed over the entire width.
