Gold-plated silver is a difficult part of the offset printing and embossing process. The reason is that the pigment particles of gold and silver are thicker than other ink pigment particles. The printing material is first absorbed on the paper, and the oxidative conjunctiva reaction occurs during the drying process. The pigment particles are easily precipitated from the binder, and the adhesion is not strong. When the other colors of the ink are printed on the gold-silver ink, it is easy to stick the ink to the bottom due to its own viscosity. Or the phenomenon of the bottom, causing waste and defective products.

Our factory is a packaging and printing enterprise. Most of the boxes produced are large-area gold and silver, and other inks are superimposed on the color. According to the actual situation, when the technician explores the silver ink, a silver-gray mixed ink prepared by black ink and a dilute agent is added to the ink, so that the hue is not changed, and the above problem is also overcome.

The effect of using a light yellow ink in the printed gold ink is also obvious. Sometimes the black ink is not enough black color on the metal ink. You can use the dark blue ink to add it to the black ink to mix thoroughly. The problem is solved.
