What problems should I pay attention to when using the printing machine?
Doing a good job in printing is the basis for ensuring the quality of printed products. If even the printing work can not be done well, then the quality of the printing produced can be imagined. Therefore, the printing plate staff should pay attention to maintaining the printing machine, and carefully and carefully during the operation to avoid mistakes and quality problems.
In order to maintain the work and the machine in the process of using the printing machine, it is necessary to keep the transparent glass plate clean, the printing machine neat and the printing film without dirt. At the same time, the exposure amount should be adjusted reasonably. When the intensity is constant, the exposure amount can be adjusted by changing the exposure time.
The development temperature, developer concentration, and development time are the main factors affecting the development of the plate printer. The longer the development time, the more sufficient the reaction of the photosensitive resin on the surface and the developer; the higher the concentration of the developer, the higher the temperature of development, and thus the more comprehensive the degree of dissolution of the exposed portion.
After the development of the plate-making machine is completed, it is necessary to carefully check and timely process the areas where the dirty spots exist. During the working process of the printing machine, the film margin will leave marks on the outside, so these marks must be processed. The processing tool is usually a revision pen. When using the retouching pen, try to prevent the movement of the graphic on the top of the graphic, to prevent the retouching paste from falling onto the graphic, affecting the quality of the graphic and causing unnecessary loss. After the correction of the graphic is finished, it is necessary to quickly wash away the repairing paste on the printing machine with water. When scouring, the method from the inside to the outside should be used to avoid damage to the graphic.
After the work machine finishes the task. Need to check whether the orientation of the mouth, the tip and the graphic of the printing plate are in the correct position, whether the graphic is intact and whether the printing plate has creases, and there are abnormal areas in the printing machine. To be processed in a timely manner.
