Definitions

  • the invention relates to a pad printing cliché and to a method for producing a pad printing cliché.
  • Pad printing clichés are known in a variety. They are usually made of plastic, metal or ceramic. Plastic clichés are extremely inexpensive, but the engraving must be made by means of a development process, which produces environmentally harmful waste. Clichés made of metal, for example steel clichés or copper plates, can be processed with a laser and are therefore much more environmentally friendly. In addition, the service life of these metal clichés is much higher than existing plastic clichés.
  • Ceramic clichés are known, for example from EP-A-0 922 590.
  • This solid ceramic cliché is produced by sintering ceramic powder in a baking process at high pressure and high temperatures. Subsequently, the cliché produced in this way must be subjected to a relaxation process lasting over weeks. This manufacturing process is very expensive and the cliché thus prepared has a homogeneous structure only in a relatively thin surface area. Otherwise, the ceramic cliché is inhomogeneous, ie it has pores that can adversely affect the printing process. If this ceramic plate is provided with an engraving, then this penetrates beyond the relatively thin homogeneous region far enough into the cliché that the reason for the engraving lies in the inhomogeneous area.
  • the engraving is relatively rough, which has the disadvantage that the engraving holds the printing ink relatively strongly, ie is hydrophilic.
  • the porosity of the ceramic plate also has the disadvantage that the amount of printing ink present in the engraving can not be set exactly, which can sometimes lead to shades in the print.
  • the ink which has previously been applied by means of a squeegee on the cliché and thereby engraved in the engraving, excavated from the engraving and applied to the object to be printed by means of a tampon.
  • the surface of the plate can be scraped off perfectly, which is why flat clichés with high accuracy and even clichés with high accuracy must be circular.
  • the evenness can be made very well with ceramic clichés by superfinishing, which also applies to roll clichés.
  • the flexographic printing process is also known, but this is not a gravure printing but a gravure printing process.
  • High pressure process is.
  • color is taken from a Einfärbezylinder with a flexible, the print image having stamp.
  • This inking cylinder consists for example of metal or ceramic and is provided on its surface with wells from which by means of the printing image having stamp the color is removed.
  • this printing method has the disadvantage that it is relatively inaccurate, since the stamp, in particular the raised portions of the stamp, both when placed on the inking cylinder and deformed when placed on the substrate, whereby the color is smeared. In addition, this does not guarantee how much color is transferred to where.
  • the invention is therefore based on the object to provide a cliché for the pad printing, which has a very long service life and with which exact quantities of ink can be precisely transferred.
  • Pad printing cliché which has a base body and a firmly applied to the body, the engraving bearing pad.
  • a multi-part construction which has a main body which serves to support and to support a support.
  • the body thus gives the pad printing cliche the required rigidity, whereas the pad has all the properties required for receiving and dispensing the ink and for squeezing the cliché.
  • the base body made of metal, plastic or solid ceramic.
  • the overlay is a flame-sprayed material that is sprayed directly onto the body so that it is solid, i. inextricably linked with this.
  • the overlay has a greater hardness than the main body. This ensures that the cliché according to the invention has a long service life, even if, for example, the base body consists of a relatively soft material, for example plastic or copper.
  • the support is an oxide ceramic spray material. Such materials are provided in powder form and applied after melting on the body. This can be done by plasma spraying or high speed spraying. In the high-speed spraying process, the molten material is applied to the surface of the base body at very high speed, which counteracts the formation of pores.
  • the overlay has a homogeneous structure and then only needs to be machined on its top in terms of evenness. Although the molten ceramic powder, although a very high temperature in the range of several thousand degrees Celsius, but has a negligible mass, the base body is not affected when applying the spray material.
  • aluminum oxide (Al 2 O 3 ), zirconium oxide (Zr 2 O 3 ), titanium oxide (TiO 2 ), yttrium oxide (Y 2 O 3 ), calcium oxide (CaO) or chromium oxide (Cr 2 O 3 ) have proven to be suitable oxide ceramic spray materials.
  • the spray material consist of these materials or contain these materials, and mixtures of these substances are conceivable.
  • Alumina has the advantage that it has good resistance to abrasion, low sliding wear and low friction. In addition, alumina is non-conductive.
  • Aluminum oxide is also resistant to many acids and alkalis. Chromium oxide has a hard, dense layer with high resistance to wear and corrosion. It is resistant to acids and lyes and the layers are well engraved by means of a laser. Zirconia is also resistant to wear and scratching. It has a high resistance to molten metal and Particle erosion. Titanium dioxide is soluble in alkalis and sulfuric acid. It is also weakly conductive. For mixtures, the above features can be combined in limits.
  • the overlay has a thickness of from 10 ⁇ m to 400 ⁇ m, in particular from 20 ⁇ m to 200 ⁇ m, and preferably from 30 ⁇ m to 50 ⁇ m.
  • the layer thickness can be chosen freely. Due to the structure produced in layers by spraying, the overlay is equally homogeneous over its total thickness. The thickness of the support need only be slightly larger than the depth of the engraving.
  • the support can be processed by means of a laser, in particular a YAG laser.
  • the laser is tuned to the composition of the material of the edition and optionally to their color.
  • the support is finely processed on its surface, in particular by means of superfinishing. It can be achieved with a tolerance of + 0.1 microns flatness.
  • the invention also relates to a method for producing a pad printing plate with a base body and a fixedly applied to the body, the engraving bearing pad, wherein the support is applied by means of a flame spraying process.
  • a flame spraying process in particular a plasma spraying process or
  • the high-speed injection method has the significant advantage that the support is firmly connected to the base body, and, on the other hand, that the support is homogeneous and free of pores over its entire thickness. Therefore, an engraving with an exact engraving depth can be generated, the engraving reason is very smooth and hydrophobic and therefore the printing medium are excavated without residue from the engraving. As already mentioned, the engraving has a defined depth and thus also a defined volume. This creates the possibility that with high precision, other media can be transmitted by means of the printing process, i. not just printing ink, but also glue, lubricants or medicines. Especially for medicines, the dosage, i. the amount of drug transferred, of particular importance. For example, a drug can be transferred to a patch, which is then supplied through the skin to the body.
  • Another advantage is that the engraving not only has a defined volume but also exact edges, so that high-precision prints can be generated.
  • the engraving not only has a defined volume but also exact edges, so that high-precision prints can be generated.
  • position and contour sharpness of the individual inks must be exactly right.
  • the ink can be completely removed from the engraving, it is ensured that it remains sterile and no impurities are carried off.
