Tips for offset thin paper printing and quality
1) when tapping the kitchen needs more waterproof and transparent plastic paper, the method of tapping thin paper and thick paper (g/㎡) is different. Tapping thin paper should be uniform and flat. The smaller the interval between tapping sections is, the better, and the spacing is the best, so as not to cause wrinkle. Generally, for the paper that is eager to be printed on the machine, only knock the drag tip to keep its mouth flat so that the paper can be fed smoothly
2) the paper presser foot should be smaller than that when printing thick paper, which is generally about 5mm
3) the paper feeding wheel shall be adjusted as light as possible, based on the smooth rolling of the paper wheel when the paper passes, so as to reduce the resistance and prevent the paper from curling
4) for machines with better optical control system, such as gaobao and Komori series offset printing machines, the paper dust at the mouth should be cleaned in time, preferably once a shift, so as not to affect the sensitivity of optical control and cause the machine to stop for no reason. Because the light control function is more important for the printing of tissue paper after the completion of this equity transfer
at this time, the jaw should be replaced. 5) the temperature and humidity of the printing workshop should be consistent with that of the paper warehouse to prevent the paper from ruffling or shrinking, which will affect the smoothness of overprint and paper feeding. Enterprises with conditions can achieve better results by using air conditioners or air humidifiers. If there are no conditions, they can improve the printability of paper by watering and drying paper
6) when printing thin paper, it is better to print a little faster, and the paper receiving system and paper feeding system will be more stable. Generally speaking, for a machine with a maximum machine speed of 10000 prints/hour, it is better to set the speed at about 6500 prints/hour; For a high-speed machine with 15000 prints/hour, it is better to set the printing speed at 9500 prints/hour
