High-precision plate-free three-dimensional hot stamping process

Abstract

The invention relates to the field of hot stamping of printing packaging products, in particular to a high-precision plate-free three-dimensional hot stamping process which comprises the following steps: a silk screen is manufactured into a silk screen plate in a silk screen photosensitive exposure and development mode, and a hot stamping pattern on the silk screen plate is obtained; according tothe silk screen plate, gold stamping UV glue is adopted as a carrier in a silk-screen printing mode, the gold stamping UV glue is printed on a printing stock, a gold stamping UV glue pattern is formedon the printing stock, and then through ultraviolet irradiation, the gold stamping UV glue pattern is cured by ultraviolet light to form a high-precision three-dimensional pattern; and a gold stamping foil is attached to a printing stock of a transparent gold stamping UV adhesive pattern obtained through hot stamping offset printing, then a hot stamping area and the gold stamping foil are subjected to hot pressing compounding through certain temperature and pressure, and the high-precision three-dimensional pattern gold stamping printed product is obtained. According to the high-precision plate-free three-dimensional hot stamping process, silk screen integral plate making is adopted, pattern positioning adjustment does not need to be conducted through a single gold stamping plate, the positioning time of hot stamping plate installation is shortened, the high-precision three-dimensional pattern has high-precision and three-dimensional effects, a traditional hot stamping process cannotsimulate the high-precision plate-free three-dimensional hot stamping process, and a certain anti-counterfeiting function is achieved.

Description

technical field [0001] The invention relates to the field of hot stamping for printed and packaged products, in particular to a high-definition plateless three-dimensional hot stamping process. Background technique [0002] The traditional hot stamping process mainly uses engraving or etching to make the hot plate according to the hot stamping pattern, and then installs the hot plate on the traditional hot stamping equipment, and transfers the hot stamping paper to the Hot stamping is done on the substrate. [0003] Because traditional hot stamping requires engraving technology to engrave the hot plate before hot stamping can be carried out. Due to the accuracy bottleneck of engraving technology, some high-definition patterns cannot be realized by traditional hot stamping. In addition, traditional hot stamping is transferred to the substrate by hot stamping paper. The hot stamping UV glue pattern has no three-dimensional effect, and the visual effect and touch effect are no...
