1. When the pattern size shift printing, lengthwise pattern size shrink. The reason: lack of margin contraction. As the plastic film tension and heated drying effects of printing, the film's longitudinal dimension greater than the contraction of printing graphics. Solution: When the plate is left to the appropriate amount of shrinkage in size; the film tension to a minimum. 2. When printing, the pattern dimension in the longitudinal direction of elongation. Reason: intaglio Size leave too much to the shrinking margin. Solution: increase the film tension. Poor reproducibility printing level 1, highlights (bright areas) is too deep. The reason: the plate too deep, too much amount of ink contained. Measures: (1) increasing the mesh; (2) reduce the ink pigment; and (3) appropriate to increase the angle of the doctor blade and the plate surface. 2. High brightness too shallow. The reason: the plate deep enough. Measures: (1) using the ink in dark colors; (2) appropriate to reduce the squeegee with the surface of the plate angle. 3. shadows (dark) too deep. The reason: the plate too deep. Solution: Due to insufficient ink drying, ink agglomeration may, if necessary, to re-exchange version. The dark tone density is not enough. The reason: the plate deep enough. Solution: Use a deep shade of ink. 5. clear ink midtone shades junction. Reason: bad ink. Solution: exchange characteristics of a good ink. Paper reel unwinding machine operation of the installation. According to the requirements of continuous printing, gravure printing machines generally use Usually web Konica Minolta Huang Jiang color card printing company, the machine model is different from the outer diameter of the mandrel uncoiler paper differ more, usually 3, 6 or 12 inches so when ordering web, first lithography, consider paper mandrel diameter size, generally require the paper web than the inner diameter of the mandrel core large 2-5mm appropriate, so the main consideration during transportation web Zhixin Changes inside diameter of the mandrel and paper; a second yellow card Jiang color printing company should also pay attention to the maximum outer diameter roll unwinding machine that can be used, if the roll diameter than this range map printing, you can not install and use. Scan during installation, check whether the deformation Zhixin, if the deformation is too large and should be repaired first, after the commencement of direction straightened paper printing market, the paper roll paper core mandrel is inserted, the distance between the two ends of the mandrel examination paper , try to roll mounted centrally. After the machine, you can compare the lateral position of the rolls, to ensure at the same lateral position. If uncoiler automatic stitching bin ink, after the web machine, according to the requirements of open-book machine, and according to the butt or lap Huang Jiang color card printing company, crossed stitching position, double-sided, single-sided adhesive tape paste. In the splicing process, a combination of print, to ensure a consistent overall diameter two roll speed. If the open-book machine manually bin Huang Jiang color card printing company, shut down after the cut web on the volume, adjust the horizontal position of the paper, directly attached to the beginning of the new web. Color card printing quotes _ beyond printing (online consultation) _ Huang Jiang color cards printed by the Dongguan City, often beyond packaging products factory provided.
