Description
Technical field
The utility model is related to screen printing technical field, and in particular to a kind of write-through screen printing equipment.
Background technology
Traditional screen printing technique by printer using the film, it is necessary to be made a plate.The film and the camera of early stage
Egative film is similar.It is as follows that plate-making flow is carried out using the film：The film with image is attached to the silk screen web plate for having applied photoresists
On, using the Hg lamp irradiation film, there is visuals the photoresists of web plate with transmitted ray, can be made photosensitive on the film, will be photosensitive
Web plate is developed, and not photosensitive part can be dissolved by the developing after development, so as to form figure on web plate.
There is following defect in the method for traditional utilization film plate-making：
1st, consumables cost is high, and traditional silk-screened method for platemaking needs to use film setter to make the film, and polychrome printing is needed
Multiple films are wanted, the film is i.e. by discarding after printing down, and consumables cost is higher compared with directly making a plate；
2nd, increase process, cause inefficiency of making a plate：Traditional silk-screened lithography process needs pattern-making egative film first, then
Longer through the printer mask-making technology cycle, thus inefficiency of making a plate also can result in more problem points and occurs and artificial
The increase of cost, time cost；
3rd, the film is fragile：The film is yielding in itself to be easily scratched, and causes its service life to be greatly affected greatly；
4th, super large web plate can not be made：Limited by film area itself, traditional method for platemaking can not make super large net
Plate；
5th, the precision of images is poor, it is impossible to meet the plate-making of small line width figure：Because traditional silk-screened method for platemaking is to pass through
What pattern egative film was replicated and completed with photoresists contact exposure, thus the loss of image detail can be caused in reproduction process, image
Precision is less than original copy, and the phenomenon is particularly evident during the printing down of thick photoresists, therefore traditional film plate-making is generally only applicable
Line width more than 50 μm.
