Manufacturing method of embossed metal color print

Abstract

The invention provides a manufacturing method of an embossed metal color print. The manufacturing method comprises the following steps that metal is prepared as a base material, the metal is rolled into a metal sheet with a preset thickness through a rough, medium and fine procedures and by rolling equipment; a laser engraving machine is used for carving a selected pattern on a steel mold; the metal sheet with the preset thickness is selected to be placed in the steel mold, and the metal sheet is punched by using an oil press, so that the pattern of the steel mold forms a raised embossed pattern on the punched surface of the metal sheet; color printing is conducted on the raised embossed pattern on the punched surface of the metal sheet; and silk-screen printing with UV photo-cured frostedink is conducted on the punched surface of the metal sheet after color printing. According to the manufacturing method, the metal sheet can finally realize a raised embossed metal product with the gravure printing effect, so that not only lines in the pattern can be reflected through embossment, but also color printing can be conducted directly on the pattern represented by the lines, and a finalproduct can have a high-precision embossed pattern which can be touched and have rich color levels.

Description

technical field [0001] The invention relates to the field of handicrafts, in particular to a method for making metal color printing prints that embody three-dimensional relief effects through lines. Background technique [0002] At present, there are a large number of gold and silver banknotes, gold and silver cards, and sheet metal products on the market. Most of these products are flat products, or are reflected on the flat surface through temperature change, fluorescence, luminous, laser, color printing and other process decoration methods. The flat product with embossed visual effect, that is, imitation embossment, lacks the real embossed touch effect. And the decoration style is monotonous and lacks new ideas. [0003] In addition to the above product categories, there are also some thin sheet relief products, such as car hangings, key chains, red envelopes and other precious metal products, but most of these products are multi-material products that are stamped after ...

Problems solved by technology

[0002] At present, there are a large number of gold and silver banknotes, gold and silver cards, and sheet metal products on the market. Most of these products are flat products, or are reflected on the flat surface through temperature change, fluorescence, luminous, laser, color printing and other process decoration methods. Flat products with embossed visual effects, that is, imitation embossment, lack of real embossed touch effect

And the decoration style is monotonous and lacks new ideas

[0003] In addition to the above product categories, there are also some thin sheet relief products, such as car hangings, key chains, red envelopes and other precious metal products, but most of these products are multi-material products that are stamped after being pasted on the base material and gold foil. That is to say, the relief is formed by a mixture of various materials, and its relief pattern is relatively rough and not refined. It uses surfaces to reflect the texture, lacks details, and cannot meet the increasing demand of the market.

And most of these products use acrylic and other transparent material shells for fully enclosed protection, so that consumers cannot touch
