Screen printing is to stretch silk fabric, synthetic fiber fabric or metal screen on a screen frame, and make a screen printing plate by hand carving paint film or photochemical plate making. Screen printing plate is made of emulsion and liquid (ammonium dichromate solution). Screen printing is the starting point of screen printing, so be careful in the production process.

Uneven ink (color difference) appears in the printing process.

1, uneven ink knife pressure? The pressure changes from time to time, resulting in different shades of ink, so the stability of printing strokes is very important.

2. Is the scraper speed uneven during printing? The speed is sometimes fast and sometimes slow, even if there is a pause in the middle, it will easily lead to different shades of ink, so the speed will remain uniform when printing.

3. Is the sharp edge of the scraper uneven or bent? The sharp edge of the scraper is uneven or curved, so the pressure is uneven when printing, and the ink color is different. At this time, it is necessary to replace the scraper or grind it.

4. Unstable scraper angle often changes the scraper angle, resulting in different shades of ink, and manual printing is easy to appear.

5. Is the screen spacing around the screen inconsistent? The mesh plates are not on the same horizontal plane, so the spacing between the mesh plates must be consistent at high speed.
