In all kinds of printing methods, dot gains will be more or less encountered. In particular, dot gains often occur in flexo and offset printing. In the case of flexo, there are not only dot enlargement problems, but also printing plates. The combination of bending deformations causes flexographic offset problems. According to this kind of situation, generally make the test printing plate, carry on the printing experiment, obtain the information that enlarges and distorts according to the experimental result, carry on the compensation treatment through pre-press processing.
In the prepress stage, â€œreducingâ€ the size of the dot in order to compensate for dot gain in printing, there are mainly two pre-processing methods: one is to adjust the level curve of dot gain, and finish before the film is out. The other is The calibration of the laser photodischarging is completed when the screen is screened. It is suggested that the second method is adopted. According to the characteristics of the printing method, the film printed by the laser image aligner is printed on the film. The dot gain is significantly reduced, and the halftone dots in the middle tone are 5% to 10% smaller than the ordinary printing plate. , And can make 0.5% to 3% of the dots are clearly reproduced on the film and plate.
The Wooden Rat Trap size and specification differently and there several designs to fit more needs. A wooden rat trap is primarily with a metal spring and plastic/metal peddle. they are easy to set and very effective. The wooden rat trap is typically set by a quick trigger. Keeping the bottom flat then putting pressure on the metal spring, attempting to connect the hook lever to the pressure plate on the other side of the trap. Finally, add a lure on the pedal.
