Hot stamping

The scientific name is called hot pressure transfer printing, referred to as hot pad printing, commonly known as hot stamping and hot silver. Heat the metal plate. Apply foil. Printed on the print with gold text or patterns, with the rapid development of hot stamping foil and packaging industry, the application of aluminum foil is more and more widely used.

UV

UV is UV, UV is the abbreviation, "UV transparent oil" is the full name, is to rely on UV irradiation to dry curing ink. At present, UV inks have covered areas such as offset printing, screen printing, ink jet printing, and pad printing. The traditional printing industry generally refers to UV printing as a printing effect process, which involves applying a layer of varnish to a pattern printed on you ( There are light, matt, mosaic crystals, glitter powder, etc.), mainly to increase product brightness and artistic effect, to protect the surface of the product, its high hardness, corrosion resistance, friction, scratches, etc., some film products are now replaced by UV can meet the requirements of environmental protection, but UV products are not easy to bond, and some can only be solved by local UV or polishing.

Hit convex, embossed

The scientific name is imprinting, and the process of forming a pattern by local variation of the printed object by pressure, which uses a concave-convex mold, causes the plastic deformation of the printed substrate under a certain pressure. As a result, the printed surface is artistically processed. Divided into cheap ordinary corrosion version and expensive laser engraving two.

3D stereo UV

Achieve surface roughness, touch, colorful, reverse UV, frosted, similar to the different effects of bronzing hot silver, greatly increased the viewing of packaging products.
