Problems solved by technology

[0003] If the pattern formed on the surface requires backlight transmission, in the traditional way, when printing the ink layer, it is necessary to use a screen to cover the corresponding area, and often need to do multiple layers of cover, there are problems such as inaccurate positioning and unclear edges of the pattern, and the overall efficiency low
The laser ink removal method can make the pattern edge clear and improve the processing efficiency, but the general laser ink removal method is easy to damage the substrate film

Embodiment Construction

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a printing processing method. The printing processing method comprises the following steps that ink is arranged on a light-transmitting base material in a full plate printing manner to form an ink layer; a printing layer is formed through silk printing, and the ink layer is located between the light-transmitting base material and the printing layer; an infrared picosecond laser device is utilized for rough scanning to remove ink in a preset area; and the infrared picosecond laser device is utilized for fine scanning to remove ink left in the preset area. The ink is removed through lasers in the preset area so as to be used for backlight transmission, the infrared picosecond laser device weak in energy is utilized for processing, and the light-transmitting base material is prevented from being destroyed by the too strong lasers. The ink removing step comprises rough scanning and fine scanning, most ink of the preset area can be fast removed through rough scanning, and the processing efficiency can be guaranteed easily. After rough scanning, further laser processing is quite close to the light-transmitting base material, and fine scanning is adopted to be beneficial to protecting the light-transmitting base material; and the ink is removed thoroughly, and the light-transmitting effect is good.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a printing processing method. Background technique [0002] In the printing industry, the processing procedure involved in the traditional ink processing method is relatively complicated, which limits the processing efficiency. For example, using PC (Polycarbonate, polycarbonate), PVC (Polyvinyl chloride, polyvinyl chloride) or PET (Polyethylene terephthalate, polyethylene terephthalate) transparent film as the substrate, printing ink on the surface of the substrate The layer plays the role of enhancing shading, insulation and adhesive backing transition layer. After printing the ink layer, the appearance layer is printed, and silk screen is done on the surface of the appearance layer to achieve functional expression and appearance display. [0003] If the pattern formed on the surface requires backlight transmission, in the traditional method, when printing the ink layer, it i...
