Debugging of ink printing machine:
Check whether the electrical control device of ink printing machine is sensitive, whether each gas valve is leaking, and add lubricating oil to each lubricating part. Cleaning ink roller, easy to use detergent or washing powder to carefully clear the mesh roll, you can use brush dipped in cleaning brush wash, do not use metal brush, so as not to damage the mesh. Adjust the roller and printing plate drum, adjust the paper feeding device, guide wheel spacing, printing pressure and slotting size, phase. Correct the parallelism of each rotating drum.
Start the main motor of the watermark, operate at a constant speed, and rotate smoothly without any abnormality.
The problem of the operation of the ink-ink printing machine
The base layer of the plate can be established by back exposure in order to obtain the required relief and strengthen the adhesion of polyester support film and photosensitive resin layer. The correct back exposure from the polyester support film can protect the fine pattern of the version during washing and prevent the relief from collapsing.
The main exposure should be carried out immediately after the back exposure, because the photosensitive activity will gradually disappear, resulting in a long main exposure time and poor exposure tolerance.
When the guarantee layer of the resin plate is torn off, the photosensitive speed of the plate is rapidly attenuated, and the film sheet is immediately placed on the plate material or the main exposure is carried out within 10 minutes so as to obtain the best effect.
The main exposure time can be determined by the main exposure test. The photosensitive resin becomes insoluble by polymerization, and the printing plate can reproduce the fine patterns on the film. Before main exposure, wipe the vacuum film by hand to drain the air so that the plate is close to the negative.
The printing plate should be dry, otherwise it will affect the thickness uniformity of the printing plate, after drying, do not let the printing plate contact with the surface of other objects, do not touch the printing surface with your fingers, otherwise it will leave traces. But before debonding, remove any spots on the surface of the printing plate. After debonding, leave residual spots on the back of the resin plate. If you do not clean these things, it will affect the thickness uniformity of the printing plate and the adhesive force of the adhesive tape. Last article: no more.
