Abstract
The process starts with the digitalization and processing of the images to b e reproduced on the ceramic piece, said images having been obtained for exampl e from a photography. The process proceeds with a lamination and photo-exposur e phase by means of photolyte and which can be carried out in a single step, f or monochromatic decorations, or several times for polychromatic (quadrichromy) decorations, specifically one operation for each color used. Further, a transport solution is applied for example with a serigraphic screen. After implantation of the image on the ceramic piece and drying thereof, the latte r is placed in a furnace at high temperature, approximately 1 050 ~C.
Description
f PROCEDURE FOR THE ORNIMENTATION OF WALL AND FhOpR TIKES
D E S C R I P T I O~N
PURPOSE OF THE TNVENTIOrT
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.
ANTECEDENTS OF THE INVENTION
At the present time for the ornamentation of ceramic surfaces the following processes are employed:
- Single baking The entire product is heated in the kiln once so that the unbaked base element or bisque 4 receives the enamel using a sprayer and later the decoration, via a serigraphic screen with a type of fixative being used between screens.
- Double baking First the base or bisque is baked, and then the coats cited above are applied. It is then returned to the kiln.
- Third baking With this option first the bisque is heated, as in the previous case, and then next, after applying the engobe as in the two previous methods, we proceed to the enamelling and a new baking phase, with the AII~iE~fDED SHEET
' -2-final decoration being applied with screens or by hand (by brush), proceeding finally to the "third bakin ' which gives the process its name. The decoration in this "third bakin ' system also tends to be done by applying pre-decorated transfers over the enamelled ceramic base.
There has recently appeared a system by which the entire process of glazing, enamelling, and decoration using rubber rollers or something similar without employing enamel sprayers or serigraphic screens.
At any rate, these approaches have their own disadvantages which consist mainly in the following:
- The surface area of serigraphic screens is very limited since, physically, the holes where the paste must pass (coloured ceramic + liquid carrier) need to be of large enough diameter for the paste to flow through with the ensuing danger of that the orifices become quickly clogged. To mitigate this problem weaves of very few threads should be used, causing a final image definition t that is notably inferior.
- The angling of each serigraphic screen is critical when working with liquid paste, which tends to expand to some degree after passing through the orifice of the screen, depending on the diameter of the points of the weave, the density of the paste, and pressure and speed of the spatula. Other besides inconveniences or defects are also suffered.

" " , ' . . , . , , . ~ " ".' ',.' '"" "' ' - Defects registering the crosses of each screen over the former, due to the very manufacture prOCe55, i.e., inherent ~.n the process itself.
Thus, 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 unequa-1 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 photolith 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 photolith.
DESCRIPTION OF THE INVENTION
The procedure for the ornamentation of wall and floor tiles that the invention proposes more than satisfactorily resolves the problem mentioned above, insuring the perfect engraving of the images selected, in black-and-white as well as colour; in glossy or flat finishes, with maximum durability and resistance.
For it, and more precisely, in a primary operative phase we proceed, after selecting the image, to the digitalisation and processing of the same for its ~hoto.IithographY, i. e. , in order to obtain a hotolith through photoli thogra by ,~'~E~D~D ~~~~

Next the transfer paper is laminated and printed. down, i. e. , e.xt~osing it to ultraviolet light, through photolith polychrome printing. This operation of lamination and printing down 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. More specifically, four photolyths will be used in the four cot our sol uti on wi th the foll owing cot ours - cyan, lrcagen ta, yellor~r and black. , Next, in a third operative stage, a commonly used transport solution is applied and allowed to dry. The enamelled ceramic substrate is cleaned, after which it is baked at a maximum temperature of 1,050° C, a baking phase performed at the same time as that of the tile so that the image becomes integrated in its enamel surface.
In agreement with the other characteristics of the invention, the baking curve is to evolve in the following manner During the first hour the kiln teiaperature is raised from room temperature to 325° C. At Zh.45min. a temperature of 700° C is reached. After 30 minutes more, the temperature reaches 1,050° C, which is maintained for 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.

According to a preferred example of the practical use of the invention and when dealing with the ornamentation of wall and floor tiles and with images in colour, the image to be applied onto the ceramic substrate in question is digitised and processed. More exactly, filming in photolith at 200 lines per inch, which equals 78.74 points per cm2 is done .
The transfer paper is laminated and printed down by magenta four-colour print photolith. The protective plastic is removed from the transfer sheet to apply the powdered magenta ceramic colour and the transfer is instantly cleaned with anti-static gauze.
Next this operation is repeated, i.e., a second lamination and insolation is performed, following the same process, with cyan photolith colour, a third with yellow and a final one with black.
. Afterwards, a commonly used transport solution is applied, either by brush or serigraphic screen. After drying, the enamelled ceramic substrate is cleaned. Then the transfer is submerged in water to loosen the image from the cardboard support. Once loosened, it is applied onto the ceramic substrat, eliminating the water and the air with a rubber spatula.

When dealing with black-and-white images or sepia, the procedure is exactly the same as described for obtaining those of colour except that only one phase of lamination and inso.iation is carried out, i.e., in black or sepia.
In obtaining black-and-white images as well as those in colour the .baking curve is the following:
