Description

A kind of carving foil printing technique

technical field

The invention belongs to the technical field of embossed prints, and in particular relates to a foil-engraved print technique.

Background technique

Traditional letterpress printing is to use a knife or chemicals to engrave or etch the blank parts of the manuscript on wood, stone, copper, zinc and other layouts, leaving the part with the image, and the part left (that is, not engraved) on the layout is convex. Since then, it is called letterpress. Ink prints made of raised parts with ink and then rubbed onto paper. However, it can only be copied on paper, and cannot be copied for relief works.

In the past, the metal embossing process was also cast by the traditional lost wax method. Each work needs to be turned into a wax mold with silica gel, and then wrapped with quartz sand layer by layer. The high temperature burns the paraffin in the shell to make the shell, and then pours the high-temperature molten copper water into the shell mold, and then smashes the shell mold to take out the cast copper relief work. Moreover, the cast copper relief work must have a certain thickness. If it is too thin, the wax liquid cannot be completely perfused and circulated in the shell mold, so that the copper plate pattern will be missing or penetrated. The process is complicated and the material is heavy and expensive. The characteristics of thin, simple, low cost, easy to copy, beautiful and unique, and wide-ranging uses of foil printing cannot be achieved.
