[0020] Step 2. The second silk-screen CD pattern: A layer of varnish is silk-printed on the entire surface of the first small dot, the wire diameter is 0.1mm, and the spacing is 0.2mm. Materials needed: Shenhua varnish (one-component ink), 550 mesh composite steel wire mesh, squeegee hardness 75A, baking temperature 150°C, baking time 4min, ink thickness 2μm.

[0021] Step 3. Screen printing white oil 1: Screen printing a layer of white oil on the entire surface of the second CD pattern: Material required: ink: curing agent: thinner = 140:1:0, screen mesh number is 350 meshes Ester net yarn, squeeg...

Embodiment 2

[0027] Step 1. The first silk-screen dots: a layer of semi-transparent black dots with a diameter of 0.4mm and a spacing of 0.8mm with a silk screen on one side of the glass. The required materials: black oil: varnish: curing Agent: thinner=100:60:15:6, screen mesh is 450 mesh composite steel wire mesh, squeegee hardness is 80A, baking temperature is 150℃, baking time is 3min, ink thickness is 2μm.

[0028] Step 2. The second silk-screen CD pattern: A layer of varnish is silk-printed on the entire surface of the first small dot, the wire diameter is 0.15mm, and the spacing is 0.4mm. Materials needed: Shenhua varnish (one-component ink), 500 mesh composite steel wire mesh, squeegee hardness 80A, baking temperature 150°C, baking time 4min, ink thickness 2μm.

[0029] Step 3. Screen printing white oil 1: Screen printing a layer of white oil on the entire surface of the second CD pattern: Material required: ink: curing agent: thinner = 140:2:1, screen mesh number is 350 meshes Ester m...

Embodiment 3

[0034] Step 1. The first silk-screen dots: a layer of semi-transparent black dots with a diameter of 0.6mm and a spacing of 0.9mm with a silk screen on one side of the glass. The required materials: black oil: varnish: curing Agent: thinner=100:60:15:6, screen mesh number is 400 mesh composite steel wire mesh, squeegee hardness 80A, baking temperature is 150°C, baking time 3min, ink thickness 2μm.

[0035] Step 2. The second silk-screen CD pattern: silk-print a layer of varnish on the entire surface of the first small dot, the wire diameter is 0.1mm, and the spacing is 0.1mm. Materials needed: Shenhua varnish (one-component ink), 650 mesh composite steel wire mesh, squeegee hardness 80A, baking temperature 150°C, baking time 4min, ink thickness 2μm.

[0036] Steps 3 to 5 are the same as in Example 2.

[0037] After the above steps, a mobile phone lens with a 3D visual effect pattern with an overall ink thickness of 15-20 μm is obtained.

Abstract

The invention provides a printing method for a pattern having a 3D visual effect on a mobile phone lens. The printing method comprises the following steps that firstly, dots are printed in a silk screen mode, wherein one layer of black dots is printed on the whole surface of one side of plane glass of the mobile phone lens by using a dot-shaped composite wire mesh as a screen printing plate and using a mixture containing black oil and gloss oil and gloss oil as ink; the diameter of each dot is 0.2-0.6 mm, spacing between the dots is 0.6-0.9 mm, and the mesh number of the screen printing plate is 400-500 mesh; secondly, CD grain is printed in a silk screen mode, wherein one layer of CD grain is printed on the whole surface of the dot layer obtained from the first step by using a CD grain composite steel mesh as a screen printing plate and using gloss oil as ink; the line diameter of the CD grain is 0.1-0.15 mm, line grain spacing is 0.1-0.4 mm, and the mesh number of the screen printing plate is 500-650 mesh; thirdly, silk screen printing is performed by using white oil; fourthly, silk screen printing is performed by using black oil. According to the printing method, the mobile phone lens with the pattern having the 3D visual effect can be manufactured through 2D plane glass.

Description

Technical field [0001] The invention relates to the technical field of mobile phone lens printing, in particular to a printing process with 3D visual effect patterns. Background technique [0002] With the advent of the information age, as a communication tool for mutual communication and communication, the role of mobile phones is becoming more and more important. The characteristics of diversification, fashion and rapid replacement of mobile phones have become increasingly prominent. On the one hand, the ever-expanding mobile phone market has directly brought about a straight increase in the number of panel orders. On the other hand, the fashion and diversification of mobile phones have placed more demands on manufacturers. Screen printing technology is one of the most important and critical processes in the production of mobile phone panels. To make mobile phones present 3D visual effects, the current methods mainly include the following two. The first: use 2.5D curved glas...
