Principles of Toning of Printing Inks for Composite Packaging Bags

1.The color tone of the printing ink for the composite packaging bag should use the same type of ink produced by the ink factory as much as possible, and the color saturation of the setting ink should be higher than that of two inks 2.If you want to use inks of several hues for color matching, you should try to use the setting inks with similar colors as the main inks for the new hues. 3.When color matching, the variety of ink should be reduced as much as possible, because the more kinds of color ink, the higher the achromatic ratio, which will reduce the transparency and saturation of the color matching ink, so it can be made with one color tone, not two colors. Ink formulation 4.When blending light-colored ink, do not use white ink as the main color, and add a small amount of primary color ink. 5.When printing composite packaging bag materials, in order to obtain light ink and still maintain the viscosity of the ink, diluent should be used, try not to use diluent, because plastic cloth is easy to absorb solvent, too much diluent, drying energy needs to be increased, and The adhesion force is reduced because the solid content is too small. 6.Ink of different manufacturers, types and varieties cannot be mixed, otherwise it will affect the gloss and fastness of printing after mixing, and may even cause ink gelation
