Understand the common problem handling of the printing machine and improve the use value of the equipment
The printing machine is a commonly used printing equipment, which is mainly used in the middle and late printing, especially in the image printing and processing. It has a great effect. The equipment is comprehensive in function, but it is also difficult to escape the problem. How to deal with it? Is there any way?
1, the image is dizzy and the blank is not clean
To solve this problem, the glass of the plate-making machine must first be kept clean. To wipe clean with alcohol, both sides must be rubbed. The transparency of the work is not enough, the penetration of light will be affected, and the version of the sun will be blurred. If the film plate and the glass plate are not tightly attached, it will also cause the sun filter.
2, PS version of the network is not true
To solve this problem, check it from the film. The dot on the film used for printing should have sufficient blackness. The dot structure on the plate should be transferred to the plate, and the covered portion should never pass the amount of light, causing the photosensitive layer of the plate to be sensitive. Otherwise, the dots on the plate will not be solid, and the dots will fall off when printing.
The dot is dizzy, we know the absolutely clear dot, the transition between the light-transmissive plane and the black-faced cladding is very steep, and it is abrupt, and the edge of the dot is actually coveted. The faint dot is opposite, the blackness is gradually increasing from the edge, so the dot produces a slope with a larger or smaller edge.
3, can not reflect the subtle part of the work
Like a hair, there are on the photo, and the plate becomes blurred. This is mainly due to the insufficient amount of exposure or the excessive concentration of the syrup when the plate is washed, and the fine parts are washed away.
