Golden Mo Yin brushs common breakdown processing technique

Pressworking in the process, often use Jin Mo, aureate and OK the effect that has to make the finishing point, the printing ink with sex of adsorption of Dan Jinmo black-and-white and move more general sex is poor, accordingly, pressworking the meeting in the process encounters many problems, produce the ingredient with all sorts of not stable quality. When use Jin Mo, want to undertake proper adjustment to Jin Mo's printability above all, presswork the move result that Jin Mo pays close attention in the process, the locomotive speed of printing machine shoulds not be too fast, the roller that send handwriting or painting often should be in groove, transfer forme at printing ink is in good condition and even ground with benefit, bear imprint substance appearance. Achieve idealer result.

Jin Mo pressworks the quality trouble that encounters in the process is more, main show is in print is lacklustre, print expands, burnt edition, print sends empty show-through to wait.

Print is lacklustre

Chemistry does not stabilize ① . Be affected with damp be affected with damp of golden Chinese ink, be heated, in be contacted with soda acid or be being shown in air, with respect to incidental chemical reaction, make glossiness damage pales and lack brightness. Accordingly, jin Mo should prevent be heated, be affected with damp be affected with damp in custodial process, appear, avoid to be contacted with soda acid material.

② printing machine instrument is not clean. Jin Mo is pressworking in the process, as a result of Mo Gun high speed runs, chafe for long be heated, accelerated oxidation rate of Jin Mo, and bring about printing ink degenerative hair is dark. Usually, printing machine every run 4 hours continuously, must rubber roll (offset print includes water roller) clean thoroughly, change new handwriting or painting afresh next, maintain printing ink fresh and luster.

③ allocates printing ink to deposit time to grow too. When Jin Mo is allocated, answer to be moved less as far as possible, maintain the dosage in 3—4 hour commonly had better, easy oxidation of time of equipment golden Chinese ink and Guo Jiurong of time of use be apart is degenerative, hair of colour and lustre is dark, affect the glossiness of the product thereby.

④ bear imprint material smoothness is poorer. Bear imprint material smoothness is poorer, the surface is rough, after Jin Mo changes the face, be permeated instantly among fiber, make surface of Chinese ink layer loses luster.

The rate of ⑤ machine is too rapid. Machine movement rate is too rapid, the quantity of heat that attrition produces is exorbitant, accelerated Jin Mo's oxidation, and lose luster, accordingly, when Yin Jinmo, machine speed relatively imprint other expression Chinese ink wants slow.

Print expands, burnt edition

① is defeated by Chinese ink to had been measured big. The printing ink quantity that carpenter's ink marker exports is overmuch, bring about heavy panel of layer of Chinese ink of surface of Chinese ink roller. Change forme face, graph article place cannot bear the printing ink of excessive, pressworking below the action of pressure, expand to print brim place necessarily, or happen play phenomenon of Chinese ink, burnt edition, discover Chinese ink has been measured big or printing ink is stuck too, answer to control amount is defeated by Chinese ink in time, want to get rid of the Mo Cengqing with redundant surface of Chinese ink roller, next divide evenly Chinese ink pressworks.
