Can you tell me how to make a good print?
Control version dirty1, the printer will wipe the glass clean; remove the dust on the original manuscript, repair the defect on the original scratch; return the unqualified original, re production. For printing plate exposure caused by insufficient dirt, if dirt is not too serious, can supplement exposure using the diffusion sheet to move the position of the light exposure; can also improve the concentration of the developer, another developer.2, check the developering temperature and development time, and adjust to the corresponding standard; adjust the developer according to the formula given by manufacturer, update the developer; developing layout to fully clean water, the use of high-quality sponge layout; maintenance of automatic developing machine.3, in addition to dirty operation should be careful, apply brush to fill in except dirty liquid, except dirty, in addition to dirty time should be kept in 20, 30 seconds; in addition to dirty liquid use should be covered tightly; layout except dirty treatment, should use water fully flush.
Dot reproduction control1, eliminate mesh halo phenomenonTimely maintenance of printer, ensure good working condition of vacuum pump, pumping enough, print, rubber gasket shelf, good sealing effect; print, in recognition of the plate and the original close tightly, can open the light exposure; collage of the original, to repair the original burr on the edge of the adhesive tape to paste. From the image as far as possible, or made of the original and the whole piece of close fit plate.2, eliminate the loss of outletsShould look at the film itself dot degree, such as film on the 50% ideas is founder, 4% ~ 5% outlets are complete, in short, to check the quality of phototypesetting film, and then judge whether the network is lost in the print process. Excessive exposure, too much concentration of the developer, will make the page should retain the loss of points or text strokes thinning. The image density of less than 1.5 of the original, thinning over the original must be re produced; through the test to determine the optimal exposure time of exposure, and to guide the adjustment of exposure operation; developering concentration and temperature, is developed according to the standard specification of the developing conditions.
4, to improve the concentration of glue, the glue fully coated evenly; after the gum of the printing plate, the layout completely dry and then printed on the machine.5, in the make-up should be possible to use transparent tape thin and clean, if the tape adhesive stuck to the printing plate, should be gently wiped to developing. When you print, to fully exhaust, minimize air layer around the imposition of tape and the original film, will have the possibility to minimize the interference phenomenon. If there is adhesive tape on the page after exposure, remove the dirt manually or remove the dirt in the two exposure
