Abstract
Transfers to be applied to ceramic or like materials normally need to be squeegeed vigorously on application to avoid trapping of air or water behind the pattern. This necessity is avoided according to the invention by providing a transfer comprising a base having a surface of soluble adhesive onto an area of which is printed a pattern of one or more glazes, colors or pigments, the pattern area being covered by a consumable cover coat, in which the cover coat is coherent but is provided with a configuration of small apertures over substantially the whole of the pattern area.
Claims1
In a transfer of the type to be applied to a substrate and subsequently fired to obtain permanent marking of the substrate, and comprising a base having a surface of soluble adhesive onto an area of which is printed a pattern of one or more glazes, colours or pigments, and consumable cover coat covering the pattern area, said transfer being removed from said base by use of a solvent to free it from said soluble adhesive, the improvement comprising:
- said cover coat is provided with a configuration of small aperatures over substantially the whole of the pattern area, the size of said apertures varying according to a half toning technique wherein smaller apertures are utilized for fine pattern detail and vice versa, the cover coat being thus rendered porous but retaining its coherence to permit escape of solvent from behind the transfer without the necessity for squeegeeing.
