  • the carrier material is, for example white paper or plastic wrap.
  • the print data included one or more bit positions per picture element. For example the value one in a bit position indicates that a black picture element is to be printed. The value Zero in a bit position indicates that on the picture element no hydraulic fluid should be applied.
  • the picture element retains the color of the carrier material.

  • a laser creates a gas bubble in the ink produces, whereupon the ink expands and a recording medium wetted.
  • a printing device and a Print roller specified to carry out the process are suitable.
  • the invention is based on the knowledge that at a change in the surface tension of a liquid, which is adjacent to a solid, one through which Interfacial tension between the surface of the liquid and contact surface and by the contact surface itself Contact angle also changes. Is the Liquid in a vessel, forcing the change of the Contact angle a change in curvature on the liquid surface.
  • the change in curvature has the consequence that at least partial areas of the surface around a certain one Move difference path, e.g. Raise or lower.
  • the difference way depends on the vessel size and is, for example 10 ⁇ m to 30 ⁇ m with a print resolution of 600 dpi (dots per inch).
  • the carrier material is on one Pick-up unit for transporting the hydraulic fluid for the individual picture elements or becomes the carrier material arranged at a distance from the hydraulic fluid, that corresponds to the difference path, so it depends on the surface tension with a large contact angle or large curvature for wetting and thus for coloring of the carrier material when the hydraulic fluid moved up to the carrier material. Is the contact angle or the curvature is small, however, so the carrier material not reached by the hydraulic fluid. A wetting does not occur and the carrier material retains its basic color in the opposite of the hydraulic fluid Area at.
  • This principle is used in the method according to the invention when printing a picture element depending on one to the relevant image element the print date belonging to the surface tension a hydraulic fluid affected. That too printing carrier material becomes the printing fluid in a distance at which hydraulic fluid with a first surface tension wetted the carrier material and with the hydraulic fluid with one of the first Surface tension deviating second surface tension the carrier material is not wetted.
  • the inventive Procedure to change the Surface tension requires far less energy than that Accelerate a drop of ink.
  • the process fluid arrives after wetting of the carrier material due to the adhesive effect between Carrier material and hydraulic fluid to the carrier material.
  • the first surface tension is greater than the second Surface tension. Which is at the first surface tension resulting surface curvature is greater than the resultant at the second surface tension Curvature.

  • the second surface tension has against it a value at which the surface of the hydraulic fluid is flat or even curved inwards. The direction the curvature is seen from inside the liquid.
  • the difference in this training is very large, so that it is possible to enlarge the support material Distance from a vessel to hold the hydraulic fluid passing out. This will result in an abrasion of the carrier material and avoid wear on the edges of the vessel.
  • the surface tension is changed in that the Temperature of the hydraulic fluid is changed.
  • the warming the liquid usually leads to a decrease the surface tension.
  • Flash lamps laser beams or laser diodes are used. Evaporation when changing the temperature in the Fluid additives containing hydraulic fluid, e.g. Surfactants, this leads to an increase in the surface tension.
  • Surfactants are surfactants, which lower the surface tension. To increase the surface tension consequently it happens when these liquid additives be removed.
  • the surfactants can evaporate already forced by a relatively small change in temperature become.
  • By removing the liquid additives the surface tension increases more than it does through the Warming drops. This is the opposite process So the increase in surface tension that leads to a Increasing the contact angle and thus increasing the Curvature on the surface of the hydraulic fluid leads.

  • This training is based on the knowledge that the Surface tension changes only with a certain inertia.
  • the surface tension remains unchanged, so that dependent wetted by the surface tension of the carrier material becomes or remains unwetted.
  • the radiation from the radiation source reaches the liquid surface in this training without first passing through the liquid.
  • the direct irradiation of the surface results in that there are liquid additives on the surface of the liquid influence with a small amount of energy to let.
  • the liquid additives are surfactants, that evaporate when the temperature rises slightly.
  • the radiation source is in this training arranged outside the vessel for the hydraulic fluid. As a result, there are no internals in the material of the vessel are necessary for supplying the energy.
  • the next step is the surface tension with the help of a time and location controllable Radiation source changed. If the radiation source is in accordance clocked at a time interval, so the Surface tension set for different picture elements become.

With a combination of timed and locally controlled Radiation source can be the printing speed increase using reasonable clock rates if, for example Radiation sources for exposing the picture elements two or more lines arranged in a row are and operated simultaneously.
  • a smaller surface tension depending on the Print data is increased.
