Problems solved by technology

The disadvantages are: products with high requirements cannot be reused; in the corrosion process of plate making, the details of fine patterns are easily lost; the phenomenon of "pasting plate" is easy to appear in the hot stamping process
In addition, the deformation of the paper is reduced, which makes the problem of inaccurate hot stamping more prominent, affects the appearance of the product, and seriously reduces the qualified rate of the product

Embodiment Construction

[0018] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0019] A kind of processing method of large-area fine bronzing and overprinting of the present invention comprises the following steps:

[0020] Toning, adjusting the color of the printing background color and the printing pattern, using the same color tone, and the anodized aluminum hot stamping foil also adopts the same color tone as the printing pattern and the printing background color;

[0021] Graphics processing, using software to do imaginary or feathering on the edge of the printed pattern;

[0022] Adjust the shape, adjust the shape of the bronzing pattern to an irregular shape or an arc shape;

[0023] Adjust the line width and spacing, adjust the line width and pattern spacing of th...

Abstract

The invention discloses a processing method for fine gilding and overprinting in large size. The processing method comprises the following steps of: color matching: adjusting the ground color for printing and the colors of printing patterns, wherein tones of the same color system are adopted, and alumite stamping foil adopts the tone the same with those of the ground color for printing and the colors of the printing patterns; graphic processing: carrying out virtual-edge adding or feathering treatment on the printing patterns by adopting software; shape adjusting: adjusting the gilding shape to be an irregular shape for a circular arc shape; line width and space adjusting: adjusting line width and space between the patterns of the patterns to be gilded; and making a gilding plate, during plate making, the gilding plate is compressed in proportions. With the adoption of the processing method for fine gilding and overprinting in large size, the printing effect is more fine and more attractive than that of the prior art, the requirements for high-grade product can be met, and the processing method can adapt to mass production, has lower cost than the traditional technology, and improved yield.

Description

technical field [0001] The invention relates to printing, in particular to a processing method for large-area fine bronzing and overprinting. Background technique [0002] Hot stamping is to use a certain pressure and temperature (usually about 130 degrees Celsius) to use the hot stamping plate installed on the hot stamping machine to press the hot stamping material and the hot stamping plate in a short time, and press the metal foil or color pigment foil The graphics and text of the hot stamping plate require the processing technology of transferring to the surface of the material to be hot stamped. Gold and silver hot stamping is also called hot stamping, and the metal foil is usually anodized aluminum foil. [0003] Bronzing overprinting is to use plates of different colors to print in stages on the same page, which can create gorgeous visual effects and is widely used. Bronzing is usually carried out after ink printing and graphics are completed, and it is a very late ...
