The printing machine is a vital part of the printing equipment, and the printing work is also an indispensable part of the entire printing production. If some problems occur during the use of the printing machine or in the printing work, it will seriously affect the quality of the printed products and the development of the printing work. So, what problems should we pay attention to in the use of the printing machine and the printing work? One: Reasonably adjust the exposure of the printing machine. In the exposure of the printing machine, the most important task is the adjustment of the exposure. Under the condition of a certain intensity, the exposure of the printing machine can be adjusted by changing the exposure time. The main methods are as follows: 1. The developer is preferably of the type provided by the manufacturer. If a developer is used, it must be manufactured in strict accordance with the concentration specification of the developer, and it needs to be thoroughly stirred to uniformly dissolve it. In addition, during the operation of the printing machine, the developer is continuously consumed and evaporated, so the developer is replenished according to the amount of work. 2. After the development of the printing machine is completed, the printed graphics and blanks should be carefully checked to clean the areas with dirty spots in time. During the use of the printing machine, the edges of the film will leave marks on the outside, so these marks should be cleaned up in time. A high concentration of developer is used for rinsing. The higher the development temperature, the longer the development time. Two: Prepare the work before printing. Preparation before printing is the basis for ensuring the quality of printing and printing. Therefore, before the printing work is carried out, it is necessary to carry out a complete and careful inspection of the printing machine to ensure that the appearance thereof is lubricated, flat and free of dirt, scratches and the like. In addition, it is necessary to keep the stencil of the printing machine to a certain extent, the film is not dirty, and the transparent glass plate is clean.
