Definitions

  • Spectacle lenses especially progressive lenses are provided by the manufacturer with permanent engravings. These permanent engravings serve to identify the position of the lens characteristics on the respective spectacle lens. For this purpose, small symbols are introduced into the surface of the progressive lens by means of a mechanical or a laser engraving process.
  • the shape of these symbols is a circular shape or the shape of a lying eight known, circular symbols usually have a diameter of 1 to 2 mm. They are at a distance from the center of the lens, in particular at a distance of 17 mm on both sides. These two points thus define the center as well as a 180 ° line showing the horizontal position of the lens characteristics.
  • more information is usually also introduced by means of a micro engraving in the surface of the spectacle lens, such as an identification of Nahsicht Schemees, the indication of the addition, the cross fitting, the distance to the 180 ° line, manufacturer or customer-specific information, logos, etc.
  • micro engravings are designed so small and thin-line that they are difficult to see later on the lens in the glasses. For this reason, the information essential for the optician is made visible in that the spectacle lens is provided with an additional clearly visible imprint on the corresponding markings, in particular on the permanent engravings.
  • printing devices such as the systems Teco TP 1, Teco TP 2, Teco TP2V or the printing machine Multi DV8 are all known from. COTEC GmbH, 61130 Nidderau, known, which is involved in the technological process.
  • the lenses move in transport shells on a conveyor belt through the production. For printing, they are removed from the conveyor belt and introduced into the printing device. In it is a measuring station, by means of which the position of the micro engravings is determined in the transmitted light method.
  • a light source on one side and an optical pickup unit connected to an image recognition unit are now arranged on the other side of the spectacle lens.
  • the image recognition unit By means of the image recognition unit, the coordinates of the micro-engravings are determined and the spectacle lens is positioned in the correct position in the printing station. Subsequently, a printing of the spectacle lens at the intended locations by means of a tampon printing process.
  • Pad printing is an indirect printing process (gravure printing principle).
  • a printing plate carries in its surface the print image to be printed. This print image is filled with ink by a squeegee pushes the color into the lower-lying print image while the excess paint cleanly scrubbed off. After doctoring becomes a more elastic Pressure pad passed over the cliché and picks up the color in order to transfer them to the object to be printed, so to print indirectly.
  • the tampon Due to the deformability of the tampon, the printing of curved surfaces (convex or concave) is readily possible. Due to its elasticity, the tampon adopts the shape of the body to be printed and can thus transfer the motif to the printed object.
  • Eyeglass lenses must be removed from the transport trays for printing and then re-inserted. This is associated with an additional handling effort.
  • inkjet printers according to the continuous ink-jet principle, for example from EP 362 101, known (so-called CIJ printers) These are in various areas (eg scratch-off, expiration date, EAN code, addressing, personalization etc.) are used.

  • a charging electrode the drops thus formed can now be charged and then deflected via a further electrode.
  • the charged or uncharged drops will now reach the substrate / product.
  • unneeded drops are already collected at the print head and fed again to the ink circuit.
  • Such printers are used in the case of objects to be printed on, in which the ink immediately makes a connection with the surface of the object, that is, for example, suction capable surfaces.
  • transparent substrates for example glass substrates or substrates made of hardened plastic, do not have these properties, which is why, according to the prior art, printing by means of tampon printing was always selected.
  • the CIJ method is not suitable in the prior art, since the droplets are deflected at a more or less large angle. This leads to distortions in the printed image on curved surfaces, which must be ruled out for precision printed images.
  • the invention is therefore based on the object to increase the flexibility in the printing of transparent substrates and to reduce the technological complexity.
  • the pattern is applied by means of an inkjet process from an ink as a printing material.
  • the inkjet process allows printing without the provision of various printing plates and is much more flexible in use.
  • the printing material is applied in the form of an ethanol-containing ink. It has been found that, on the one hand, an ethanol-containing ink has better wetting properties on a transparent substrate, in particular a glass substrate, and on the other hand, the solvent in this ink vaporizes rapidly, so that the ink quickly solidifies on the substrate, even though the substrate itself has no suction properties having.
  • the ink By heating before printing or during printing, the ink already reaches a preheated substrate and solidifies immediately.
  • the heating thus also represents a kind of bonding between the ink and the substrate surface.
  • the substrate is heated after printing.
  • the solidification process of the ink which is substantially due to drying, i. expelling solvent after the ink particles are accelerated on the substrate.
  • the substrate is irradiated for heating by means of infrared radiation.
  • This has the advantage that the heat source is arranged at a distance from the substrate. Since a transparent substrate absorbs relatively little of the radiation, heating takes place in particular partially in the area of the ink particles, so that a temperature load on the substrate can be kept low.
  • the substrate may be exposed to a warm air stream for heating. This can be advantageous for certain materials of the transparent substrates, for example in glass, because it heats the entire substrate uniformly and thus stresses can be avoided. In addition, the drying effect improves.
  • the pattern in multiple colors. Since the pattern consists of individual ink particles as described above, they can also be made of differently colored ink. Since these ink particles are very small, it is also possible by optical color mixing different colors appear by arranging differently colored ink particles from the primary colors of the subtractive color mixture next to each other.
  • ink particles of the same or different colors can be set close to each other. This is important for the production of optical color mixtures as well as for the creation of closed surfaces.
  • the raster width is selected in a first printing process so that the ink particles do not run into each other. After a drying step of, for example, 2 seconds, further ink particles are introduced into the interspaces. This step can be repeated several times until the desired tightness of the dot matrix is achieved. Thus, better printing results can be achieved at the edges of the pattern.

  • the precision of the printed image can also be improved by targeted distortion.
  • the printed image is composed by an electrostatic influence of ink droplets separated by an ink jet, different path lengths result at a curved substrate at different deflection angles.

  • the idea according to the invention consists in distorting the printed image for the curved substrate relative to a printed image for a planar substrate in such a way that when the printed image appears on the curved substrate, it is eliminated.
  • the targeted distortion takes place via the control of the print head. It is expedient to design the control that imaginary grid lines of the pattern to be printed are already distorted in the control program. Since the pattern changes when printing through the transverse Deflection of the ink droplets takes place to the printing direction, the distortion of the printed image will also take place substantially transversely to the printing direction. In other words, imaginary grid lines that lie in the printing direction are bent when printing the pattern on curved substrates compared to the printing planar substrates. The method now "bends" these grid lines, contrary to their tendency to distort, even before printing, so that a linear printed image is produced during printing.
