Technique for transfer printing porcelain image by using ink-jet printer and its transfer ink

Abstract

A ceramic picture transferring technology using ink-jet printer includes digitalizing a picture, processing and color separating by computer software, ink-jet printing of picture, brushing powder, transferring and calining. Its ink for transferring is prepared from water-soluble high-molecular filming material, emtrol polyoxyvinylether or polyoxyvinyl ester of fatty acid as surfactant, polyol as drying time regulator, and water. Its advantages are high productivity, clear picture, lifelike colors, and high weatherability.

Description

technical field [0001] The present invention relates to a ceramic decoration process---an ink-jet printer transfer printing porcelain image technology and its transfer printing ink. Background technique [0002] The existing technology is divided into traditional crafts and modern crafts. The traditional craft is to use ceramic pigments to carry out hand-painted and spray-painted decorations on unfired embryos or on fired porcelain; modern crafts use screen printing to print images and decals. Chinese patent application (CN1063643A) has introduced a kind of photosensitive ceramic image technology. The production efficiency of the traditional process is low, the price of the finished product is expensive, and the graphic quality is greatly affected by the quality of the workers; the investment of modern process equipment is large, the cost of plate making is high, and it is not suitable for single-piece or small-batch production by sampling. The photosensitive porcelain imag...

Problems solved by technology

This is because the pigment is not only coarse in particle size, but also insoluble in the solvent, which makes the ceramic ink very viscous, which can easily cause the nozzle to be blocked or not sprayed at all, so it cannot be used directly as an inkjet printer ink.
