Definitions
- the present invention relates to printing methods for the transmission of
- High-pressure method known in which the printing elements of the printing form are raised, while the non-printing parts are recessed. These include, for example, the book printing and the so-called flexo or anil impression.
- planographic printing methods are known in which the printing elements and the non-printing parts of the printing form lie substantially in one plane. This includes, for example, the offset printing, in which, strictly speaking, the inked drawing on the printing plate is not printed directly on the substrate, but is first transferred to a blanket cylinder or a blanket and then printed by this only the substrate. If in the following of printing material is mentioned, but should both the actual substrate, that is, the material to be printed, as well as any transfer means, such as. As a blanket cylinder to be understood.
- a third method is the so-called gravure printing process, in which the printing elements of the printing form are recessed.
- An industrially applied gravure printing process is the so-called scoring gravure printing.
- a through-printing method is still known in which the ink is transferred through screen-like openings of the printing form to the printing material at the printing sites.
- Printing systems are: laser printers, thermal printers and inkjet printers. Digital printing processes are characterized by the fact that they do not require printing forms.
- Ink printing method in which in a suitable ink jet, the water-based ink is briefly heated to boiling by electrical impulses, so that a gas bubble develops in a flash and an ink droplet is shot out of the nozzle.
- This method is well known by the term "bubble jet".
- Printing method unspecified, in particular from the document EP 0 530 018 A1 printing method are known in which the inks are applied to a solid film and detached from it.
- the Inks in a solid phase so that the support on which the ink is applied, after a printing process must be completely replaced.
- Very high viscosities for the printing inks are set forth in US 2016/0167400 A1, so that this is only suitable for processes in which the support must be completely replaced after each use. Hints for a
- Printing material is possible. In this method, however, has the disadvantage that the filling of the wells is very difficult due to the small well diameter. Therefore, it is proposed in DE 100 51 850 to apply the printing substance essentially forming a continuous film on the ink carrier.
- the energy can either be transferred directly into the printing substance or initially in an applied on the ink carrier absorption layer, which in turn emits the energy to the printing substance.
- special pressure substances must be used, which are able to supply the energy
- the absorption of light in the ink occurs within a relatively large volume that passes through the laser beam. For some colors, the energy is not fully absorbed. The absorption is also strongly dependent on the printing substance used and the actual thickness of the printing substance on the ink carrier. Due to the relatively large volume, adding the energy is absorbed, a relatively large amount of energy must be introduced into the printing substance to the necessary for the setting of a pressure point volume and / or
- Pressure point size has the consequence. To ensure that the desired pressure point is set in each case, therefore, significantly more energy must be introduced into the printing substance than is normally necessary for inducing the desired position and / or volume change of the printing substance.
- a generic printing method is set forth in DE 102 10 146 A1.
- printing inks as previously stated in DE 197 46 174 or DE 100 51 850, are heated by a laser beam and thereby transferred from a color carrier to a printing substrate.
- absorption bodies are used to improve the process.
- colorfast decors should be able to be processed, glass colors can be processed or inks can be used for electronic circuits.
- the process should be as simple and inexpensive
- the decor which can be obtained by the method should have high image sharpness.
- Printing method are provided in subclaims 2 to 6 under protection.
- the present invention is a printing method for transferring printing substance from a color carrier to a substrate, in which the pressure substance undergoes a change in volume and / or position with the aid of an energy-emitting device which emits energy during a process time in the form of electromagnetic waves characterized in that the printing substance comprises a high molecular weight binder.
- the substrate is not subject to any special restrictions.
- inorganic materials are used in their usual manner
- Grain size distributions can be used, no Sieblager needed, so that further cost and organization benefits are provided, since no provision of a Sieblagers is necessary.
- the printing system can be operated with a very short setup time, the design can be completely transferred from a computer that can be remotely located in the printing system.
- the designs on the PC can be changed as desired, so that very individual designs are possible. Due to the relatively low additional costs, the market share of individual designs can be increased. Since the printing is digital, any patterns and a serialization or individualization of the individual printed substrates are possible.
- inorganic materials can be used in their usual particle size distributions, without the need for a complex fine grinding process as in the conventional ink-jet process. There, the particles must be in the range ⁇ 1 pm. Through the grinding process, the pigments are damaged and lose color strength, so that several times must be printed on each other in order to obtain sufficient color intensity. Despite the fine milling process, nozzle clogging and sedimentation problems are not uncommon in conventional ink-jet processes. These problems can not occur in the method according to the invention.

- highly coherent monochromatic laser light a relatively high amount of energy can be dissipated to a very small area with very short light pulses.

- absorption bodies are used, which is smaller than the wavelength of the electromagnetic waves, preferably less than 1/10, particularly preferably less than 1/50 of the wavelength of the electromagnetic waves.
- the pressure point size is controlled by the amount of energy released by the energy-emitting device.
- brightness differences of the image to be printed are realized by varying the printing dot size.
- the printing takes place line by line, wherein areas to be printed within a line are formed by line segments arbitrarily selectable length and arbitrary selectable position.
