To adjust to the best point of view, but also consider the network depth, screen printing scraper position and printing speed and other factors. Network points too deep, the angle should be larger.
Screen printing ink squeegee pressure on the product quality will have a very important impact, the size of the pressure according to network depth and graphic level adjustment. If the plate cylinder is too long and corrode
intact, the applied pressure will be greater. Because of corrosion deep intaglio network, but the edge of the pattern prone to burr and so on. However, the pressure is too easy to scratch the ink in the shallow Mesh hole, resulting in shallow net part printed out; and the pressure is too large will make the contact angle smaller, hard to scratch the excess ink page layout, resulting in accumulation of ink scraper, resulting Cut line. Under normal circumstances, good working ink scraping system, the contact angle of about 60 ° is appropriate.
Pay attention to grasp the intensity of screen printing ink squeegee
Screen printing ink squeegee too light pressure will not work, will have haul hair and other failures. The solution is appropriate to the blade edge blade and the printing plate at the interface of hair dryer, hair dryer available special hair dryer.
Screen printing Ink scraper used for a period of time there will be burrs, rips and other phenomena, the doctor does not work effectively knife, then you need to sharpen or replace the new ink scraper. In actual work, sometimes the screen printing squeegee rupture phenomenon can be polished or padded to extend its service life, to save the cost of screen printing ink squeegee, and secondly, to solve the corresponding quality problems.
