Three pieces of maintenance information about printing equipment
Small experience in printing cylinder maintenance:
(1) Before leaving work every day, the press operator should clean the shoulder iron (roller pillow) of the plate cylinder and rubber cylinder.
(2) When changing the rubber cloth, clean the surface of the rubber roller with pure alcohol, gasoline or car wash water, then dry it with a cloth, and finally add RESOST7-3 anti-rust oil on the surface of the plate cylinder and rubber roller with a cotton cloth or a brush. Add twice in succession, with an interval of 5 minutes to dry.
(3) The liner paper used for the printing plate cylinder and rubber cylinder is soaked in engine oil and then dried and used again, so that the effect is better, or it can be cut to a suitable size with a film of appropriate thickness.
Solutions to the inaccuracy of several overprints in bill printing:
Our factory is the main printing unit for tax invoice printing in Hebei Province. Because the printed products are mostly 3 to 6 pairs, and the quality requirements are high, several sets of overprints must be accurate. In the past, the sample was printed on the machine that was printed first, and the other machine was printed like this, but the phenomenon of inaccuracy of several sets of overprints often occurred, which caused a large number of products to be over-stitched. In my work, I have summarized the method of unifying the side and front regulations to solve the problem of inaccuracy of several overprints in bill printing, so that over-stitch binding no longer occurs, and the quality and output are greatly improved.
Specific methods: â‘ Unified side rule: design a 3mm H line on the printing plate, and the H line against the edge of the paper is 0.5mm thick. Just make it register with the edge of the paper during printing. â‘¡ Unified pre-regulation: When printing the same product, make the pre-regulation consistent, and the operators shall strictly follow the same size.
Handling of scratched plates by hard objects:
When printing large quantities of prints, every time 3000 prints or paper is loaded, the plates and blankets need to be cleaned. Sometimes there is a hard object on the cloth for cleaning the printing plate. If you do not pay attention, the printing plate will be marked with a line of dirty marks. Reprinting the plate is a waste of work, time, and waste; using a revision paste, the dirty marks are not coated with the photoresist, so they cannot be repaired.
Treatment method: Dip a clean cloth with a clean cloth, then a little dampening powder, and rub it lightly on the dirty marks. When starting the machine, first fill the plate with water and run it a few times, then lower the ink roller, and the dirty marks will disappear.
From this, don't underestimate the importance of rag cleaning.
Lip gloss was invented by Max Factor in 1930. He wants to develop a lip product that can make the lips of the film bright and shiny. Inspired by movie actresses, women began to follow this makeup trend, leading to the popularity of lip gloss.
The earliest commercially available lip gloss was Max Factor's X-Rated4, which was launched in 1932. The original formula was sold until 2003.
Similar to Lipstick, lip gloss is a mixture of waxes, oils, esters and pigments.
The difference between lip gloss and lipstick products is the bright, transparent, or translucent cover layer. Generally, the ratio of oil component/wax component is relatively high, and the pigment content is relatively low (0~5%).
Lip gloss comes in many forms and used in different ways. It can be packed in a small cylinder and applied with a round or inclined applicator stick or built-in Lip Brush; it can also be packed in a soft squeezable plastic tube, which can be passed through the nozzle or with your fingertips or Apply with lip brush.
The basic lip gloss will only add gloss to the lips without discoloration. Color lip gloss adds color and gloss. Shiny lip gloss has a bright undertone, with or without color.
