Laser transfer printing method without printing plate

Abstract

The invention discloses a laser transfer printing method without ruling film. It takes transfer printing on ceramic and glass. The method includes the following steps: printing image and text on small film paper or large film paper through laser printer; covering cover glue on the small film paper or large film paper, drying; while printing, dipping small film paper or large film paper in warm water until the small paper mesophragm separated from bottom paper; putting the small paper on the printing object, removing bottom paper, and remaining image and text on the object; drying to gain the product. The invention does not need ruling film and the color is natural and vivid. It has the advantages of rapid printing speed, high efficiency, etc.

Description

technical field [0001] The invention relates to a printing method, in particular to a plateless laser transfer printing method. Background technique [0002] At present, the transfer printing technology includes water transfer printing and thermal transfer printing technology. The commonly used water transfer printing and thermal transfer printing methods at home and abroad are to use screen printing, offset printing, and inkjet printing to transfer the graphics and characters. Text is printed on transfer paper or film and then transferred to the item to be printed. Among them, screen printing has the advantages of thick ink layer and bright colors. It is the most commonly used transfer printing method at present, but printing sets of color pictures needs to make multiple plates, the color transition is poor, and multiple printings are required. Complex and strict requirements on the printing environment. Offset transfer printing realizes color printing and natural and per...

Problems solved by technology

Among them, screen printing has the advantages of thick ink layer and bright colors. It is the most commonly used transfer printing method at present, but printing sets of color pictures needs to make multiple plates, the color transition is poor, and multiple printings are required. Complex, strict requirements on printing environment

Offset transfer printing realizes color printing and natural and perfect color transition, but the thin ink layer cannot meet the special requirements of some items such as ceramics and glass decals, and multiple plates need to be produced, which has certain requirements for printing volume

Inkjet printing transfer technology is to add eco-solvent ink or thermal transfer ink to the Epson inkjet printer cartridge, or to print on special transfer paper in an external continuous supply ink cartridge. This method does not require plate making, and the color is bright, but For some items, such as ceramics, which require high temperature printing, it cannot be realized, and the speed is slow, the cost is high, and the ink will cause great damage to the printer nozzle, so mass production cannot be realized
