Definitions

  • the invention relates to a process for the production of high-resolution flexographic printing products, to a process for the production of a flexographic printing tool and to flexographic printing products produced by the process.
  • the task is to develop a flexographic printing process that retains the advantages of flexographic printing (short makeready times and lower cylinder costs) and achieves a flexographic printing result that is barely distinguishable from a gravure printing product.
  • the invention therefore relates to a process for the production of flexographic printing products, characterized in that printing is applied to a carrier substrate with the aid of a flexographic printing tool whose halftone dots are placed deeper at a pressure percent value between 1 and 10%.
  • Another object of the invention is a flexographic printing tool, characterized in that halftone dots are set lower with a pressure percent value between 1 and 10%.
  • Another object of the invention is a method for producing a flexographic printing tool, characterized in that halftone dots are set deeper with a pressure percentage between 1 and 10% by defocusing the laser tool or by modulation of the laser beam.
  • Another object of the invention are produced by the process according to the invention flexographic printing products.
  • These high-resolution flexo prints can be used to replace gravure in the 70-grid family.
  • the resolution is chosen according to the current state of the art, according to the flexo standard between 44 and 60 rasters / cm. With the direct laser engraving, the fine resolution of the laser beam can generate raster geometries up to 90 l / cm. This makes it possible to model the standard rotogravure families of 70 l / cm in flexo printing.
  • the pressure can be applied to all carrier substrates.
  • Carrier substrates are, for example, carrier films, preferably flexible transparent plastic films, for example of PI, PP, MOPP, PE, PPS, PEEK, PEK, PEI, PAEK, LCP, PEN, PBT, PET, PA, PC, COC, POM, ABS, PVC , Fluopolymers, PTFE, Teflon in question.
  • the carrier films preferably have a thickness of 5 to 700 .mu.m, preferably 5 to 200 .mu.m, particularly preferably 5 to 50 .mu.m.
  • metal foils for example Al, Cu, Sn, Ni, Fe or stainless steel foils having a thickness of 5-200 ⁇ m, preferably 10 to 80 ⁇ m, particularly preferably 20-50 ⁇ m, may also serve as the carrier substrate.
  • the films can also be surface-treated, coated or laminated, for example, with plastics or painted.
  • Aluminum foils and aluminum composites are mainly used for covers in the dairy sector, but other applications are possible
  • carrier substrates also paper or composites with paper, for example, composites with plastics with a basis weight of 20 - 500 g / m 2, preferably 40 - 2 are used 200 g / m.
  • woven or nonwovens such as continuous fiber webs, staple fiber webs and the like, which may optionally be needled and / or calendered, can be used as the carrier substrates.
  • fabrics or webs of plastics such as PP, PET, PA, PPS and the like, but it can also be woven or nonwovens made of natural, optionally treated fibers, such as viscose fibers are used.
  • the nonwovens or fabrics used have a weight per unit area of about 20 g / m 2 to 500 g / m 2 . If necessary, the nonwovens or fabrics must be surface-treated.
  • the dot size of the range 1% to 10% is so small that the mechanical stress of the grid point during printing destroys the elastomer cylinder.
  • the screen dots are rubbed off directly from the surface by the contact pressure on the substrate.
  • 1 means the shoulder height, 2 the dressing, 3 the relief height, 4 the relief depth; A solid-color printed areas B in the grid-printing areas, C high-lights or fine line.
  • the task can be solved by lowering the points in the print percentage between 1 and 10%.
  • the contact pressure from the cylinder to the substrate is held by the raster tone values between 10 and 100%.
  • the halftone dots which transmit tonal values of 1 to 10%, touch the substrate only slightly due to the lowering in the nm range, but they are not mechanically stressed.
  • the raster points are set between 100 nm and 100 ⁇ m, preferably 500 nm-50 ⁇ m, particularly preferably 10-20 ⁇ m, lower.
  • support strips can be attached to the left and right of the cylinder.
  • the support strips can be used to increase the process capability and reproducibility of the printed products in flexographic printing on all printing cylinders.
  • the support strips then form the so-called print carrier for the contact pressure.
  • the fine grid points get no stress.
  • the support strips are advantageously 2-3 mm ready and can with a tone value of 20 - 100%, particularly preferably 50% equipped. However, they can also be executed as 100% printed areas interrupted. The interruption may be at 90 degrees or at any other angle to the direction of compression.
  • the support strips also have the advantage that, for example, in the case of motives which are only partially arranged on the cylinder, the cylinder runs more smoothly in the printing machine. In this case follows on a printing area a non-printing area. In this area, the pressure on the substrate then abruptly decreases and abruptly returns to the area to be printed. This arrangement causes vibrations in the printing unit, which are visible in the printed product.
  • flexographic printing products can be produced which, even with a screen> 60 l / cm, can hardly be distinguished from a corresponding gravure printing product in terms of precision and quality.
  • the products produced by the process according to the invention with the flexographic printing tool according to the invention can be used as container covers, packaging materials, security elements and the like, as well as all printed matter for publication or publishing printing and technical or functional films such as e.g. RFID, printed conductors etc. can be used.
