Method for producing inlay-like prints on wood and device for attaching such prints

The invention relates to a method for serial production Production of inlay-like prints on wood, wood veneer or the like. Using wood color glazes.

Color glazes for wood are very thin and were made previously used to tint or color wood or wood veneers or just to protect them. Since the translucent color glazes penetrate the wood, the wood veneer is treated without the

709831 / 083S

To cover the structure of the wood grain. So far, such glazes could only be applied to wood for flat surfaces Paints can be used and a second treatment with the same or a different shade could be used can only be carried out after the first treatment has dried, as the color glazes flow into one another. So up to now it was not possible to apply multi-colored motifs to one wood or veneer at the same time or even to apply different colors on top of each other in such a way that certain shades result.

It is therefore an object of the present invention to open up the possibility of using such wood color glazes expand and in particular a method for the serial production of xntarsia-like prints on wood, wood veneers or the like. to create by means of such wood color glazes.

According to the invention it is provided that commercially available wood color

glazes preferably by means of an silk-screen glaze paste solidified on the basis of turpentine and screen-printed onto the wood, the wood veneer or the like. be applied. In addition, a novel use is in accordance with the invention created such wood color glazes after their solidification, namely their use for manufacturing of intersien-like prints on wood, wood veneers or the like. Since these color glazes are no longer

709831/0835

can flow, can easily Eild motifs on wood, veneer or the like. imprinted and there can be several glazes different color are brought on top of each other, so that other shades result. By mixing or solidifying the colored glaze with a glaze paste based on turpentine results in a jelly-like appearance transparent ink, which is suitable for printing by means of screen printing on the said materials, namely Wood veneers or the like., Particularly suitable. Because of the transparency and tint of the glaze colors

Wood can largely use all common color tones and gradations be designed with a very sharp edge. Overprinting several times does not result in any falsifications or stains by bleeding out of the printed areas or by running into one another the solidified color glazes. Nevertheless, the solidified color glaze still has its original property, namely to penetrate into the wood surface or into the veneer that the natural structure of the The wood grain is retained or emphasized even if the color changes.

The wood color glaze is expediently mixed into the glaze paste slowly, preferably within about 10 minutes. The mixing ratio is chosen so that essentially two parts of glaze paste with one part of wood color glaze be mixed. The solidified wood color glazes can be done by means of the screen printing process

The cup-shaped body is preferably provided with a slot-shaped fastening opening, so that a certain tolerance is still possible when assembling several plates arranged one above the other or next to one another. If the bolts have a blind hole, the the entire depth of the cup-shaped part can be used, because the head of the fastening screw can be countersunk in this blind hole.

If the bolt-like body has a central, continuous mounting hole, it can also be attached to the back of the printed Plate can be fixed by means of a screw. For this type of fastening, it is useful if to achieve a larger contact surface of the collar of the bolt-like body the associated cup-shaped hollow body protrudes and is provided with mounting holes, wherein the collar is preferably screwed onto the bolt-like part is. In the same way, the cup-shaped body can also be attached to its base facing -ünde with a preferably be provided with screw-on ring base with mounting holes. In this way it is also possible to adjust the fastening device steplessly, so that the printed plate in the desired Distance from the base can be attached.
