Influence Factors of Platemaking Precision in Screen Printing

When making screen printing plates, platemaking accuracy is mainly related to the following factors.

(1) Screens include the types of screens used, the height of the screen mesh, the thickness of the wire diameter, the size of the screen opening area, the size of the screen expansion and contraction, the method of weaving the screen, and the color of the screen.

(2) Frames, including the material of the frame, the size of the frame, and the strength of the frame.

(3) The size of the tension.

(4) The choice of stretch angle.

(5) The method of bonding the frame and the screen.

(6) Pre-treatment of the screen.

(7) Photosensitive materials, including sensitivity level, resolution level, adhesiveness of photosensitive materials, expansion and contraction rate of photosensitive film, photosensitive film thickness and photosensitive film hardness, water resistance, solvent resistance, abrasion resistance, and resistance to printing The rate of high and low.

(8) The sensitizing agent blending time, the time after blending.

(9) Coating method of a sensitizer.

(10) Drying methods and conditions, including drying temperature, humidity, and drying time.

(11) Printing, including the type of light source used, the length of the exposure time, and the distance between the substrate and the light source during exposure.

(12) The density of the photographic plate master.

(13) Development, including developing methods: water development, warm water development, drug development; development conditions: temperature, soaking time, type and use of the water sprayer, and the like.

(14) Drying temperature and time after development.

(15) The choice of secondary exposure time.

(16) Revised edition.

Http://www.huigong.com.cn http://www.hc360.com

【Hc360 HC screen printing industry special channel】 Ke Tuite water hardener WR Hardener A and WR Hardener B is a two-component hardening agent (or hardener), can be used in all Autosol emulsion or Plus series emulsion, purpose Increase the water resistance and printability of the screen template.

Specific usage:

1, 1 part A + 1 part B, mixed.

2, screen exposure, dry after imaging.

3. Brush the A, B mixed hardener on the dry screen printing surface.

4. Brush A and B mixed hardener on the screen ink surface.

5. Place the screen at room temperature (about 26°C to 30°C) and allow it to dry naturally for about 2 hours.

6. After being dried naturally, put it in the oven again, the temperature is about 50°C, let it heat and chemically harden for about 1 hour.

7, hardened screen can not be stripped.
