Kraft paper pay attention to printing color

In order to get better color reproduction in kraft paper printing, it is more difficult than printing with SBS paper. In particular, accurate color reproduction on ordinary kraft paper plates requires more care than printing on bleached kraft paper plates. Because the ordinary kraft paper itself is dark brown, the effect of printing ink is very different from the effect of printing on bleached white paper. Therefore, it is best to use bright colors of ink, the use of more eye-catching colors, so that the printing effect is better. Soft colors and light colors are the most difficult to achieve the desired results of ink density, opacity and wear resistance. In addition, if necessary, a little white can be added to the ink first, which will be conducive to achieving the required soft tone or light color, which is of great use for copying soft colors and light colors. With the increasing maturity of printing technology, some manufacturers even use UV ink, which effectively improves the printing color effect. At present, almost all ink manufacturers have developed inks for primary color cardboard, and many ink manufacturers have also developed inks for printing on kraft paper. Therefore, before determining the best plan for the work, we should consult the ink manufacturer, select different formula inks according to the printing needs of the factory, refer to the ink chromatography provided by the ink manufacturer and the printing effect of the ink on different papers, and finally determine the best ink to choose.
