Apparatus (10) for color decoration of an article of ceramic material, comprising: a digital color printer (1 1), in particular of the laser type, advantageously constituted by a printer model already available in the market; - a separation bath (12); and a baking furnace (13); wherein the digital color printer (1 1) is configured both to print (21), using a plurality of cartridges (C1, C2, C3, C4) of colored ceramic toners (C, M, Y, K) accommodated in respective printing units (1 1-1, 11-2, 1 1-3, 11-4) of the digital color printer (11), a colored image (I) of ceramic toner on a printing support sheet (F), and to directly apply (22), using a special cartridge (C5), containing a ceramic fondant (FO), housed in a respective printing unit (11-5) of the same digital color printer (1 1), a layer of this ceramic fondant (FO) on the colored image (I), of ceramic toner, printed on the printing support sheet (F), and wherein the decal (D) formed by the colored image (I) of ceramic toner, printed on the printing support sheet (F), and by the layer of ceramic fondant (FO) applied on the image (I) during the printing step, is separated in the separation bath (12) from the printing support sheet (F) and then applied on the surface of an article (M) to be decorated, that finally is baked in the baking furnace (13), so as to stably fix the colored image (I) of ceramic toner on the surface of the article (M) and thus obtain the final decorated article (A). Advantageously the apparatus (10) allows to avoid quality defects, typical of conventional decal decoration processes, such as unwanted halos formed around the image that decorates the final article and the so-called "stamp effect", and moreover implies limited decoration costs since the apparatus uses a usual digital color printer, without modification, available in the market.

The present invention relates to a method and an apparatus for diluting a liquid colorant. The method and apparatus are especially suitable for use in conjunction with the manufacture of colored concrete products. The method of spraying includes, providing a liquid colorant, diluting the liquid colorant with a diluting liquid, and spraying the diluted liquid colorant onto uncured concrete and/or on mold surfaces prior to filling with uncured concrete. The apparatus for spraying a diluted liquid colorant includes a flow path for a diluting liquid, a liquid colorant pump connected to the flow path, a mixer for mixing the diluting liquid with the liquid colorant, and a sprayer connected to the flow path.

The invention provides a method for applying a multi-colored, long lasting engraved mark on the surface of brick (10) or other similar ceramic objects. Masks (40) are used to separate coloring agents (16) during the process such that variegated designs are created. A groove (14) may be placed in the brick (10) over the area to be marked to provide a substratum for coloring agent (16). The coloring agent (16) is placed in the groove (14) and subjected to heating such that it melts and fuses with the brick (10) surface bearing the groove (14). The coloring agent (16) is comprised of colored glass frit particles. A laser (12) is optimally used for providing both th egrooving and heating steps.

The apparatus for distributing powders on a support in a predetermined pattern, comprises: a belt conveyor (2) for transporting the support (3); a head for applying the powders (1), located above the conveyor (2), which head (1) comprises a ring-wound closed continuous belt (4) exhibiting a plurality of perforations arranged according to a predetermined pattern, the perforations being of a size which enables passage of predetermined quantities of powders; means for controlling a supply and delivery of powders through the perforations and for keeping the continuous belt (4) clean. The head also comprises means for controlling a movement of the continuous belt (4) in synchrony with a movement of the conveyor (2).

A method for producing a wall, roadway, sidewalk, or floor (10) of cementitious material having the appearance of natural stone (16) and mortar (18) including a base (12) with an outer surface (14) with a plurality of irregular shaped protrusions (16) disposed in a random pattern to simulate natural stones (16) and a plurality of simulated grout lines (18) formed therebetween, the method including the steps of preparing a cementitious material, pouring the cementitious material into a form, vibrating the cementitious material, allowing the cementitious material to cure, forming the base (12) with the outer surface (14), releasing the base (12) with the plurality of irregular shaped protrusions (16) disposed in the random pattern to simulate natural stones (16) and the plurality of simulated grout lines (18) formed therebetween from the form, coloring the outer surface (14) and accenting the plurality of simulated grout lines (18).
摘要:
Items are decorated using a silk-screen process with liquid glaze whereby the items (9) are positioned at a distance (A) from a matrix (2), through which the decorating fluid is forced, so that contact between said items and said matrix is avoided. The decorating fluid is selectively associated with the said matrix and subjected to transferring means (7) for transferring the fluid to the items. Said transferring means being capable of subjecting the decorating fluid to dynamic forces greater than the force due to gravity. The decorating fluid is projected onto the said items by virtue of the said dynamic forces.
摘要:
Embodiments of the invention combine pigmented and soluble salt digital ink technologies by dispersing water-soluble metal salts as particles in a non- aqueous inkjet ink fluid. The metal salts are dispersed as pigment-like particles, and not as a dissolved solute.
