One. Be diligent according to the rules. Due to the continuous movement of the screen printing plate during printing, the screen printing plate and the frame are collided and vibrated in the round-trip operation, and small displacement often occurs between them. In this way, it is easy to have the problem of inaccurate overprint and affect the quality of products. Therefore, we should look at the rules frequently in order to find problems and adjust them in time.
II. Check the samples frequently. If the product is found to be dirty, wipe the screen with a clean cotton cloth immediately. Most of this happens because there are broken plastic films or ink crusts on the screen plate of silk screen printing, which are dry and block the screen plate. If the ink color is uneven or becomes light, it may be that the ink viscosity is too thick. Stop the machine immediately, dilute the ink viscosity with solvent, and wipe the graphic part of the layout with gasoline to prevent ink seepage or screen blocking, so as to facilitate continuous work.
Three. Semi finished products shall be stacked neatly. Normally, the semi-finished products are placed neatly on the shelf. If the semi-finished products are equipped with windows, the protective film shall be pasted as soon as possible after passing through the oven to prevent the windows from being polluted. If the raw material is a paper product, the two sides of the paper must be hung and stacked, otherwise the paper will form an upper bow due to its own gravity, and the two sides of the paper will be warped and uneven, which will make it difficult to transfer the paper during printing and often break the paper. If the paper stack is not flat, it can be leveled with cardboard. At the same time, the height of the paper stack should often be adjusted with the adjustment knob of the paper separation mechanism, so that the paper can be transmitted smoothly and the printing process can be carried out smoothly
