Definitions

• the present invention refers to a new process for the ornamentation of wall and floor tiles by making it possible to reproduce any type of design, especially photographic motifs or images, on them.
• the procedure permits the reproduction of such images in black-and-white as well as colour.
• the present technological state in the area of application of the invention shows an area of difficulty associated mainly with a lack of exact registry and the consequent impossibility of working with elevated weaves in order to obtain high-quality photographic images in the generation of weave points and unequal point density and in the use of larger points in the process, the serigraphic screen, with which still more point definition is lost, since it is probable that a point of photolyte is found in the intersection between two threads of the screen making it impossible to obtain a motif in the serigraphic panel identical to the photolyte.
• transfer paper is laminated and insolated through photolyte four-colour printing.
• This operation of lamination and insolation should be repeated as many times as the number of colours to be used in the printing make necessary, according to intention whether said printing is monochrome or polychrome, as previously mentioned.
• a commonly used transport solution is applied and allowed to dry.
• the enamelled ceramic support is cleaned, after which it is fired at a maximum temperature of 1,050° C, a firing phase performed at the same time as that of the tile so that the image becomes integrated in its enamel surface.
• the firing curve is to evolve in the following manner:
• the kiln temperature is raised from room temperature to 325° C. At 2h.45min. a temperature of 700° C is reached. After 30 minutes more, the temperature reaches 1,050° C, which is maintained for 10 minutes, only to be lowered afterwards to room temperature for a period of 2h.30min.
• a glossy or flat finish is achieved by incorporating more or less flux into the ceramic colours so that they melt with more or less facility in order to obtain more or less brilliance.
• the image to be applied onto the ceramic piece in question is digitised and processed. More exactly, filming in photolyte at 200 lines per inch, which equals 78.74 points per cm 2 is done.
• the transfer paper is laminated and insolated by magenta four-print photolyte.
• the protective plastic is removed from the treadle sheet to apply the powdered magenta ceramic colour and the probe or treadle is instantly cleaned with anti-static gauze.
• a commonly used transport solution is applied, either by brush or serigraphic screen. After drying, the enamelled ceramic support is cleaned. Then the probe or treadle is submerged in water to loosen the image from the cardboard support. Once loosened, it is applied onto the ceramic piece, eliminating the water and the air with a rubber spatula.
• the firing curve is the following:
