Abstract: A graphics adaptation method for printable ceramic supports. Images are printed on sample ceramic supports starting from an original image file. A sample printed image is acquired. Sample points representative of the sample image are selected. Original points present in the original image file are also selected. A point-based matching is sought between the sample points and the original points, on the basis of which the original image file is modified and an adapted image file is determined, thus adapting the graphics of the original image file to the graphics of the sample image. A graphics adaptation system based on the method is also described.

Abstract: A method for decorating in thickness a ceramic slab, comprising the following steps:
preparing, on a decoration surface (10), a first soft decorated layer (L1) of ceramic material endowed with a decoration (V);
progressively transferring, by deposition, the soft decorated layer (L1) from the decoration surface (10) to a first deposition surface (50), situated at a lower height than the decoration surface (10), thus progressively forming on the first deposition surface (50) a second soft decorated layer (L2) which has a head (H) and a tail (T);
progressively transferring, by deposition, the second soft decorated layer (L2) from the first deposition surface (50) to a second deposition surface (83), situated at a lower height than the first deposition surface (50), starting from the tail (T) of the second soft decorated layer (L2), thus progressively forming on the second deposition surface (83) a third soft decorated layer (L3).

Abstract: A cleaning device for printing heads arranged in a group along an alignment direction (Y) with a lower surface lying on a main plane (T). The device comprises a collecting head (2), movable along the alignment direction (Y) on the main plane (Y), in contact with or near the lower surfaces of the heads. The print head (2) is movable between a first and a second position that are located at the ends of the group of heads. The collecting head (2) is provided with an inlet opening (21) for collecting material from the heads (T).
