First of all, ink printing press printing color should be pure, a batch of no color. The advantage of waterborne ink is that the color of carton printing is pure and bright, so we must attach great importance to it. There is no significant difference between quality and color ink, good handle, sticky silk, appropriate concentration dilution of water or alcohol solvent without precipitation, condensation, mixing with wood rods without bubbles, mixed with other color ink affinity, all phases dissolved, ink with purity, no abnormal reaction. On the contrary, it cannot be used. After the best batch printing is completed, or in the use of the same ink cartridge, there will be color. The reason is that when the original ink diluted with water or alcohol solvent is not sealed and exposed to air for a long time, the chemical composition of the ink and the oxygen in the air react and decrease the dye, and the light ink is also decomposed.
Secondly, in order to ensure the clarity of printing, the first board, in order to select resistant, elastic, high-quality materials, and the layout of the thickness of the board should be consistent, the thickness of the resin version not less than 4mm, with 6 ≤ 7 mm rubber version is the best. Whether it is negative proofing, or manual knife engraving, the layout must be neat, writing patterns, lines, not less than the depth of 3mm, unaligned text mode overcrowded, arc smooth thinking, uniform thickness, line should be straight, smooth. When printing ink is transferred to the corresponding light, ink roller ink should not be too thick, moderate pressure roller, printing ink uniform, no significant indentation frame imprint surface is better.
so that the printing effect of the ink roller can be improved, the printing effect of the ink roller can be improved, the printing effect of the ink roller can not only be achieved, but the printing quality of the lead polar plate is worse, in particular in the small text, the pattern is complex, the line is fine, And the surface printing speed of the low ink box which is not less than 800 rpm is not uniform, and the phenomenon of dew is finished. The fast ink is too thick and easy to blur, and it is also designed to prevent the paper, paper, and the like from entering the printer to stick to the board. If there is a paper chip adhesive, stop immediately and dip the alcohol with a clean cloth.
