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
The present invention relates to a kind of mobile-phone lens printing technology, particularly a kind of typography with 3D visual effect pattern.
Background technology
Along with the arrival of information age, as the communication tool of communicating with each other with exchange, the effect of mobile phone is more and more important.And the feature of the diversification of mobile phone, fashion-orientation and the quick replacementization becomes increasingly conspicuous especially.On the one hand, the expanding day of mobile phone market, the straight line directly bringing panel amount on order rises, and on the other hand, the fashion-orientation of mobile phone and diversification propose more requirement to manufacturer.Screen printing technique is the most also one of the most key technique during mobile phone faceplate is produced.Make mobile phone present 3D visual effect, existing method mainly contains the following two kinds.The first: adopt 2.5D bend glass to realize 3D visual effect.In this scenario, though present different visual effects from different angular observation Mobile phone mirror sector-meetings, because the edge of cover glass is thin compared with central area, edge's strength of glass weakens widely, and the probability of this place's fragmentation can increase.The second: adopt the technique adding etching by silk-screen on 2D flat glass to reach 3D effect, as provided a kind of production method of glass surface 3D decorative pattern and the etching solution for the method in Chinese patent application CN201410394473.But the operation of this technique is various and yield is low, and thus cost is not low.Therefore be badly in need of that research and development are a kind of can print and the printing process that vision after printing can present 3D effect seems particularly important on 2D flat glass.
Summary of the invention
Therefore the invention provides a kind of can to print on 2D flat glass and vision after printing presents the printing process of 3D effect.
The invention provides a kind of printing process of mobile-phone lens 3D visual effect pattern, comprise the steps, step one, silk-screen dot: the one side use point-like clad steel silk screen being included in mobile-phone lens flat glass is half tone, use comprises the mixture of dirty oil and gloss oil for ink whole silk-screen one deck black dot, the diameter of described dot is 0.2 ~ 0.6mm, spacing between dot is 0.6 ~ 0.9mm, and described half tone order number is 400 ~ 500 orders; Step 2, silk-screen CD line: use CD line shape clad steel silk screen to be ink whole silk-screen one deck CD line for half tone with gloss oil on the dot layer that step one obtains, the wire diameter of described CD line is 0.1 ~ 0.15mm, and strain line spacing is 0.1 ~ 0.4mm, and described half tone order number is 500 ~ 650 orders; Step 3, silk-screen white oil: use point-like polyester grenadine or clad steel silk screen to be half tone whole one or more layers white oil of silk-screen on the CD lamina that step 2 obtains; Step 4, silk-screen dirty oil: use point-like polyester grenadine or clad steel silk screen to obtain having the mobile-phone lens of 3D visual effect pattern for half tone whole silk-screen one deck dirty oil on the CD lamina that step 3 obtains.
In the present invention, any one the large surperficial silk-screen dot in two large surfaces of used mobile-phone lens flat glass all can.Those skilled in the art's easy understand, described CD line is the lines of similar finger print, and it becomes large, to reach 3D stereoeffect, as seen Fig. 2 in dazzling line shape gradually by little.The patterned appearance svelteness made after step 2 of the present invention, anodontia lacks, without sticking with paste the bad phenomenon such as line.
In preferred the present invention, in the ink in described step one, also comprise curing agent and diluent, and the weight ratio of described dirty oil, gloss oil, curing agent and diluent is 100:50 ~ 60:10 ~ 20:3 ~ 8; In step one, the frictioning hardness of silk-screen is 75 ~ 85A, and after silk-screen, baking temperature is 130 ~ 160 DEG C, and baking time is 1 ~ 4min, and gained ink thickness is 1 ~ 3 μm.What described curing agent and diluent were such as commonly used for this area is purchased curing agent and diluent, and wherein the Main Ingredients and Appearance of curing agent is such as amine, and the Main Ingredients and Appearance of diluent is such as ether and/or ketone.
In preferred the present invention, in described step 2, the frictioning hardness of silk-screen is 75 ~ 85A, and after silk-screen, baking temperature is 130 ~ 160 DEG C, and baking time is 1 ~ 4min, and gained ink thickness is 1 ~ 3 μm.
In a kind of detailed description of the invention, the ink in described step 3 also comprises curing agent and diluent, and the weight ratio of white oil, curing agent and diluent is 140:1 ~ 3:0 ~ 5; In step 3, half tone order number is 300 ~ 380; In step 3, the frictioning hardness of silk-screen is 75 ~ 85A, and after silk-screen, baking temperature is 130 ~ 160 DEG C, and baking time is 1 ~ 4min, and gained ink thickness is 4 ~ 7 μm every layer.Curing agent in step 3 and the material of diluent and source and the curing agent in step one and diluent identical or different.
Preferably, the silk-screen number of plies of described white oil is 3 layers, and more preferably, when this 3 layers of white oils of silk-screen, after ink used, half tone, frictioning hardness, silk-screen, every layer of ink thickness of baking temperature, baking time and gained is all consistent.
In a kind of detailed description of the invention, the ink in described step 4 also comprises curing agent and diluent, and the weight ratio of dirty oil, curing agent and diluent is 100:8 ~ 15:2 ~ 8; In step 4, half tone order number is 300 ~ 380; In step 4, the frictioning hardness of silk-screen is 75 ~ 85A, and after silk-screen, baking temperature is 130 ~ 160 DEG C, and baking time is 15 ~ 25min, and gained ink thickness is 3 ~ 9 μm.Curing agent in step 4 and the material of diluent and source and the curing agent in step one and step 3 and diluent identical or different.
In a kind of detailed description of the invention, before being also included in step one, Ultrasonic Cleaning is carried out to described flat glass, to improve the adhesive force of ink and glass.
In a kind of detailed description of the invention, the gross thickness of the ink layer obtained after step 4 is 20 ~ 25 μm.
The first technique of the present invention's design, silk-screen dot tentatively produces stereoeffect, and helically line shape is large by little change gradually for the CD line of second technique silk-screen, forms a kind of vision 3D effect pattern in conjunction with first technique.The technique of silk-screen white oil enhances 3D stereoeffect and interception, and can adjust white ink integral thickness according to client's different colours LAB (color model) value demand, last one silk-screen dirty oil reaches complete shading effect.
