Adjustment And Correct Use Of Printing Rubber Roller

Regardless of the type and model of any printing machine, after the new equipment is installed in place, the printing rubber roller must first be installed by a technician and a lead machine. The installation level of the rubber roller must be adjusted properly. It must be in close contact with the ink roller and the printing plate. Both are indispensable. Printing practitioners know that the height of the letterpress is 3.14mm, which is consistent with the height of the typeface, and the PS plate is relatively low at 1.2mm, so you must be careful when installing and adjusting the rubber roller. If the printing product is printed with a background color, the rubber roller can be adjusted a little lower with an error of ± 0.5mm. In this way, the ink transferred from the ink roller to the printing rubber roller is more uniform, and the same is true when the printing rubber roller is reflected on the printing plate. The effect of the printed product is pleasing to the eyes. If it is not the case, the phenomenon of ink sticks and ink channels will appear.

When printing text, the height of the rubber roller is basically the same as or slightly lower than the text version. This allows the printing rubber roller to gently rub the printing plate, so that the text is printed very clearly, cleanly, and the wear surface of the rubber roller is small. Not easy to damage, can extend the life of the printing plate. Use a roller for adjustment. Before use, take out the printing plate and let the rubber roller horizontally extend in and out several times. The ink dot size on the rubber roller will be displayed immediately. The operator can determine the level of the rubber roller according to the different needs of printing. Fasten the top wire. In this way, the height of the rubber roller does not change during high-speed printing.

If we lack patience when using rubber rollers, and we are anxious to debug and save trouble, the following situations will occur: (A) The surface of the rubber roller is damaged, slag is dropped, the text printing is missing pens, the text is blurred, or even appears. Blindness and glue jumping. (B) The text is inked differently, and even the surface of the printed product has only text marks but no ink color. (C) If the rubber roller is adjusted to be too tight with the ink-transferring rubber roller, it will also twist the printing rubber roller and cause economic loss and equipment accidents.
