Abstract
The invention relates to a printing process of sheet materials for a mobile lens. The printing process adopts a wire mesh forme and silver printing ink for printing the surface of the lens and simultaneously uses a tunnel furnace and an oven to bake, so that the brightness of the surface of the lens achieves the brightness effect of a metal membranous layer. The printing process comprises the following steps: firstly, manufacturing a manuscript and outputting a ruling film; secondly, preprocessing the sheet materials; thirdly, sensitizer stencil making (stretching, coating photosensitive emulsion, and exposing and developing); fourthly, preparing the printing ink; fifthly, printing; and sixthly, baking. The invention has the advantages that because the plating films of the sheet materialsand the corrosion process after being printed are eliminated, not only the appearance defect generated in the plating film and the corrosion is indirectly eliminated and the yield of products is improved greatly, but also the productive efficiency of the products is improved.
Description
Technical field
The present invention relates to the sheet surface typography, particularly a kind of printing process of mobile phone lens sheet.
Technical background
The screen request of lens of handset protection at present is highlighted metallic mirror surface effect, and this effect all is to adopt metal coating technology.Because, sheet materials such as PC, acrylic are being carried out in the plated film, plated film expense height and sheet material cause product percent of pass to reduce through occurring various defectives behind the plated film.And after using minute surface silver printing ink directly common printed, the additive reaction in printing ink and the printing ink can appear, and cause minute surface that spot is arranged, do not reach highlighted mirror effect.Therefore in repetition test and development process, inquire into and how to adopt the alternative traditional metal coating technology of silk-screen printing technique to realize that the printing of mobile phone lens sheet is the important topic that the technician faces.
Summary of the invention
The objective of the invention is, the appearance quality for fear of adopting traditional coating process to cause mobile phone lens sheet to be prone to provides a kind of new printing process of mobile phone lens sheet especially.This process using screen printing forme and printing minute surface silver printing ink use the baking of continuous tunnel furnace and baking oven simultaneously, specular brightness are reached bright effect of metallic diaphragm.Thereby eliminate the bad order defective that in coating process, produces.
The technical solution used in the present invention is, a kind of printing process of mobile phone lens sheet is characterized by and follows these steps to carry out:
(1), original copy is made and the output of film sheet
Carry out computer according to layout and handle, make film with laser phototypesetting technology then;
(2), sheet material pre-service
At first sheet material is cleaned, advance the baking box baking then, baking temperature is 73 ± 5 ℃, and stoving time is 60 ± 5 minutes;
(3), photosensitive lithographic
1. net stretches tight: silk screen is stretched tight make screen printing forme on screen frame, the net tension force that stretches tight is 24 ± 3N/cm;
2. be coated with photoresists: the screen printing forme of making is placed be coated with photoresists on the coating machine, the thickness of photoresists is 7 ± 1u, puts into oven drying then, and oven temperature is set at 40 ± 2 ℃, sets 30-50 minute drying time;
3. exposure develops: will be coated with the screen printing forme of photoresists and the film of making and send the exposure machine to carry out exposure, the exposure time set is 120-150s, exposure after developing machine develop, the most laggard oven for drying, light sensitive plate is made at this moment;
(4) allotment printing ink
Get original-pack high light microscopic face printing ink and add 3-5% rigidizer, took out standby in 2-5 minutes through the concussion of printing ink concussion machine;
(5) printing
At first set printing parameter, wherein scraper hardness: 75/90/75 Shore degree; Net distance: 2～3mm; Scraper angle: 60～70 degree; Pressure: 2～3kg/cm
2The pretreated sheet material of learning from else's experience is taken off behind the diaphragm to be positioned at the light sensitive plate of making and is begun printing on the printing machine, and printing back normal temperature left standstill 30 minutes;
(6) baking
At first the continuous tunnel furnace temperature is set at 60 ± 3 ℃, travelling speed is made as 5m/min, and oven temperature is set at 73 ± 5 ℃, and stoving time is set at 35～50 minutes, and the sheet material that will finish printing then send continuous tunnel furnace to dry, and puts into the baking oven baking again.
The present invention has following beneficial effect: because the plated film of cancellation sheet material and printing post-etching process, the open defect of not only having eliminated indirectly in plated film and can having produced in the corrosion has improved the qualification rate of product greatly, and has improved production efficiency of products.
Embodiment
The present invention will be further described to adopt the PC technology for printing sheet material below in conjunction with lens of handset, and its concrete processing step is as follows:
(1), original copy is made and the output of film sheet: carry out computer according to layout and handle, make film with laser phototypesetting technology then;
(2), sheet material pre-service: at first adopt pure water that sheet material is cleaned, advance the baking box baking then, baking temperature is 75 ℃, and stoving time is 62 minutes;
(3), photosensitive lithographic:
1. net stretches tight: silk screen is stretched tight make screen printing forme on screen frame, the net tension force that stretches tight is 25N/cm; Silk screen adopts T300 order silk screen.
2. be coated with photoresists: the screen printing forme of making is placed be coated with photoresists on the coating machine, the thickness of photoresists is 7 μ, puts into oven drying then, and oven temperature is set at 38 ℃, sets 30 minutes drying time;
3. exposure imaging: will be coated with the screen printing forme of photoresists and the film of making and send exposure machine to expose, the time shutter is set at 130s, exposure after developing machine develop, the most laggard oven for drying, this moment, light sensitive plate was made;
(4) allotment printing ink: get original-pack high light microscopic face printing ink and add 4% rigidizer, took out standby in 4 minutes through the concussion of printing ink concussion machine; Printing ink need not to add thinning agent, avoids adjuvant and printing ink to react.
(5) printing: at first set printing parameter, wherein scraper hardness: 75/90/75 Shore degree; Net distance: 2.5mm; Scraper angle: 65 degree; Pressure: 2.5kg/cm
2The pretreated sheet material of learning from else's experience; take off behind the diaphragm to be positioned at the light sensitive plate of making and begin printing on the printing machine, printing back normal temperature left standstill 30 minutes, and its effect is the adjuvant in the volatilization printing ink behind the normal temperature; avoid printing ink oxidization takes place in hot environment, cause brightness deterioration.
(6) baking: at first the continuous tunnel furnace temperature is set at 60 ℃, travelling speed is made as 5m/min, and oven temperature is set at 73 ℃, and stoving time is set at 40 minutes, and the sheet material that will finish printing then send continuous tunnel furnace to dry, and puts into the baking oven baking again.
Succeeding in developing of printing process of mobile phone lens sheet thoroughly eliminated the printing surface that sheet material produced and open defects such as spot occurred in original technology.
The printing machine of this process using is east, the Kunshan automatic material returned serigraphy of the four-column type type printing machine of producing far away, and miscellaneous equipment (as coating machine, exposure machine, continuous tunnel furnace etc.) is industry common apparatus.
