Problems solved by technology

However, this logo printing method needs to go through the steps of laser engraving, which is time-consuming and costly, which is not conducive to mass and rapid production
In order to save costs, another printing method appeared, that is, to print the background color and the logo on the substrate at the same time. Although there is one less laser engraving processing step, it is easy to cause blurring between the background color and the logo, which makes the logo deformed. illegible and unattractive

Embodiment Construction

[0012] Combine below Figure 1 to Figure 4 The logo printing method according to the embodiment of the present invention will be described in detail.

[0013] In step S101, a substrate 10 is provided, and the substrate 10 is made of a light-transmitting material. In this embodiment, the substrate 10 is a mobile phone key cap, which includes a pressing surface 11 and a printing surface 13 opposite to the pressing surface 11 . In order to make the substrate 10 have a smaller roughness, the pressing surface 11 and the printing surface 13 can be polished or polished.

[0014] In step S102, the substrate 10 is cleaned. In this embodiment, alcohol is used to wipe or wash the printing surface 13 of the substrate 10 to remove oil stains, dust, lint, etc. on the surface.

[0015] In step S103 , electrostatic dust removal treatment is performed on the substrate 10 . In an embodiment, an electrostatic dedusting gun (not shown) is used to perform electrostatic dedusting treatment on t...

Abstract

The invention relates to a mark printing method which comprises the following steps in turn: providing a base plate; spraying printing ink onto the base plate, thereby forming a mark layer; solidifying the mark layer; spraying the printing ink on the periphery of the mark layer, thereby forming a base color layer; and solidifying the base color layer. The mark layer after being solidified is under a solid state; the sprayed base color layer is under a liquid state and has surface tension; and under the action of the surface tension of the base color layer, the base color layer has a trend of automatically reducing, so that an obvious isolating phenomenon is generated at a joint of the base color layer and the solid mark layer, the halation between the base color layer and the mark layer is efficiently avoided, and a boundary between the base color layer and the mark layer is clear and visible and is easily identified.

Description

technical field [0001] The invention relates to a logo printing method, in particular to a logo printing method for printing logos on keys. Background technique [0002] When printing the logo on the button, the multi-layer background color is usually printed on the button substrate first, and then the shape of the logo is engraved on the background color layer of the button substrate by laser engraving, so that the logo formed on the substrate can pass through the backlight. When it is exposed, the logo is printed on the key substrate. However, this logo printing method needs to go through the step of laser engraving, which is time-consuming and expensive, and is not conducive to mass and rapid production. In order to save costs, another printing method appeared, that is, to print the background color and the logo on the substrate at the same time. Although there is one less laser engraving processing step, it is easy to cause blurring between the background color and the ...
