Thermal transfer-printing method for gold stamping

Abstract

The invention discloses a thermal transfer-printing method for gold stamping. The thermal transfer-printing method comprises the following steps: preparing a pattern and a substrate to be printed, printing an ink absorbing coating, printing an adhesive layer, spreading powder, removing powder, heating and curing, and transfer-stamping. A release film used by the method disclosed by the invention is equipped with a metal electroplated coating which can have metal luster such as gold color or silver color; while the pattern subjected to thermal transfer-printing needs metal luster effect, the ink absorbing coating and the adhesive layer are printed on the gold-stamping release film, so that the adhesive layer and the metal electroplated coating are adhered together; during transfer-stamping,a contact area between the metal electroplated coating and the adhesive layer is transfer-stamped onto a target material, and a non-contact area of the metal electroplated coating and the adhesive layer is still kept on a release film, so that the pattern to be subjected to gold stamping is stamped on the target materials such as cloth through a thermal transfer-printing way, and thus, the thermal transfer-printing method is simple to operate, is good in effect and is low in cost.

Description

[technical field] [0001] The invention relates to a hot stamping thermal transfer printing method. [Background technique] [0002] Thermal transfer printing is also called hot stamping. Thermal transfer printing generally prints the pattern on the release film and other substrates first, then sprinkles the hot-melt powder on the release film, then cleans up the excess powder, and then heats it up. The molten powder is melted and solidified on the patterned release film to obtain a patterned release film, and finally the pattern is transferred to the target material such as cloth by hot pressing. Thermal transfer printing has the advantages of bright colors, rich layers, low production cost, and not easy to fade. Therefore, it has broad market application scenarios. [0003] When the pattern needs the effect of metal color such as gold and silver, if the thermal transfer method is used, it is necessary to make the metal material into ink first. However, the process of making...

Problems solved by technology

[0003] When the pattern needs the effect of metal color such as gold and silver, if the thermal transfer method is used, the metal material needs to be made into ink first. However, the process of making metal material into ink is very difficult and costly, and the The ink that comes out is easy to precipitate and block the nozzle, and it is easy to damage the printing equipment. The maintenance cost of the equipment is high, and it has no practical application value in thermal transfer printing.
