  • Print for example, using an inkjet process
  • the line-shaped drying of Fig. 1 - in the form of a Line extends transversely to the feed direction of the print image carrier the continuous heat radiator - enables an acceleration of the process, e.g. by higher Drying temperatures with which the print image carrier acts becomes.
  • Heating for example, by a heated one Transport role
  • FIG. 10 and 11 illustrate the example of a point unprinted carrier paper (Fig. 10) or a printed one Place (Fig. 11), as is, depending on the irradiation time, temperature and vapor pressure on or in Develop carriers.
  • the reference symbol is shown 18 the temperature profile and the reference number 20 the vapor pressure curve on or in the printed image carrier 10 and in Print image 12.
  • the energy input takes place in the direction of arrow 22 using full-line (broad) infrared radiation; the Arrow 24 shows (arrow size proportional to the respective Energy) the absorption in the carrier or in the printed image. Only a very small amount of energy (arrow 26) is from Carrier transmits and occurs at the opposite of the radiation Page again.
  • the object of the present invention is therefore a generic Device for drying printing ink or Develop ink to make both shorter Drying times, so higher printing speeds with continuous operation, can be made possible without the print carrier being adversely affected. Also are intended to be energy efficient and universal for a wide variety of Print image carriers, including thermosensitive print image carriers, be significantly increased or broadened.
  • the task is accomplished by the device with the features of claim 1 and the method according to the claim 14 solved.
  • Pressure device means any device that is suitable is one that requires subsequent heat drying Apply printing ink to a print carrier; next to the Inkjet printers mentioned by way of example belong to this for example also pen plotters, thermal transfer printers or the like. Devices.
  • the heat source is a point Emits beam
  • the print image carrier is small compared to the printed image carrier and usually around a minimum line width of one is adapted to the respective printed image, but also smaller or can be bigger.
  • such devices are also encompassed by the invention, in which a Printing lying, unprinted carrier areas from one applied, controlled heat radiation.
  • a control unit for the printing device such as a computer, generates a printed image to be evaluated directly as an electronic data signal and the print image data based on their position the printed image carrier the surface sections to be heated (Points) correspond directly to corresponding position data the heat source positioning device.
  • page-oriented printer languages such as Postscript, PDF, HTML or the like should be a good basis for this offer, so that when such, readout unit provided in accordance with further training which at Scanning device described in the aforementioned embodiment can be omitted.
  • the drying effect triggering infrared radiation with regard to performance Setting the radiation spectrum and pulse frequency so that depending on a particular ink or ink, here an optimum drying is achieved. So in particular a pulsed radiation with a pulse frequency ⁇ 20 KHz with energy output ⁇ 2 watts as particularly suitable for conventional Proven inkjet printer.
  • a heat radiator use different illuminants or spot types:
  • Lamps which - for the purpose of improved Adjustment or setup - also spectral components in the have visible area.
  • Such lights can then with suitable focus means, for example one Concave mirror and / or optical lens unit, for pinpoint accuracy Generation of heat radiation can be provided.
  • suitable focus means for example one Concave mirror and / or optical lens unit, for pinpoint accuracy Generation of heat radiation can be provided.
  • a laser in particular offers the advantage of one extremely responsive control and focus speed, so there is practically no delay due to each Alignment of the lamps is done.
  • a so-called high-power flash lamp as a radiation source to use, or again a full line Spotlight consisting of a plurality of arranged side by side Single radiators, which are only selective and can be controlled depending on a print image.
  • a such an arrangement increases the drying speed that can be achieved further.
  • the present invention is advantageously suitable for use with a variety of possible image carriers.
  • Next Common paper, coated or uncoated, is therefore in particular also thermal paper can be used; add cardboard boxes, Plastics, plastic films, textile substrates or the like.
  • the device according to the invention and the inventive method for drying printing ink or ink achieves that - in contrast to the known State of the art - the energy input to the concrete Print image is limited and so with regard to necessary Energy consumption as well as undesirable burden on the unprinted carrier areas are optimized.
  • the print carrier 28 can either be a continuous, Endless bearer, or a sheet which is guided in the direction of arrow 32.
  • a suitably trained control unit 34 such as a PC
  • a printhead 36 known and not shown printing device the printed image on the paper support 28 according to the electronic Control signals from the computer.
  • a sensor receives one, for example line-by-line scanner the print image and in turn converts this into corresponding signals; such scanner heads or scanner strips are as such also known from the prior art and react usually on the different light reflection from unprinted or printed areas.
  • directable heat source 40 in response to that scanned printed image patterns by the unit 38 thereupon becomes a control signal in the control unit 34 for a movable or transverse to the feed direction 32 directable heat source 40, in the present case by realizes a pulsed laser, generates, and synchronized to Printing by printhead 36, only delayed by that Runtime between printhead and heat source 40, this runs the print image in an energy and temperature optimized manner to selectively only the printed, still moist Apply heat to surfaces to dry them.
