Synthetic Paper Printing and Post Press Processing        Synthetic paper is one of the fastest growing printing materials in the printing industry. It has both the durability of plastic and the printing performance of paper. It is stronger and more durable than traditional paper.Synthetic Paper Printing and Post Press Processing printing ink   Synthetic Paper Printing and Post Press Processing       For ordinary printing parts, if the water ink balance is well controlled, the conventional paper ink can achieve satisfactory printing effect. For multicolor live parts with high overprint accuracy, if paper with high solvent content is used.Synthetic Paper Printing and Post Press Processing       The ink will lead to the deformation and distortion of printed graphics and text, especially for low quantitative synthetic paper. In this case, it is recommended to use special ink with high solid content. The content of mineral oil in this ink is very low […]

Printing Ink Viscosity       In plastic printing, the viscosity of ink has a great impact on the quality of packaging printing. The printing effect can be effectively improved by adjusting the viscosity of ink.Printing Ink Viscosity       There are two situations: one is that the ink of the latter color dissolves the previously printed color, causing discoloration or tailing and ghosting. At this time, the ink viscosity of the latter color should be increased; Another situation is that the ink of the latter color cannot be printed on the ink of the former color. At this time, reduce the viscosity of the ink of the latter color.Printing Ink Viscosity       There are two situations: one is that the ink of the latter color dissolves the previously printed color, causing discoloration or tailing and ghosting. At this time, the ink viscosity of the latter color should be increased; Another situation is that the ink of the latter color cannot be printed on the ink of the forme […]

The gripping force of the paper gripper row of the embossing cylinder is different If the holding force on both sides of the paper holding tooth row of the embossing cylinder is insufficient, the trailing tip of the paper will wrinkle; If the gripping force on one side is insufficient, the corresponding trailing edge is wrinkled; If the gripping force in the middle is insufficient, the middle part […]

Solution to Discoloration of Gold Silver Ink Printing        Ink and printed products lose the color of gold, making the color grayish black and dull, which is a common fault in gold ink printing.        Gold ink is a printing ink made of gold powder, which is a mixed metal powder composed of copper powder and a small amount of zinc powder and aluminum powder.       The speed of the gold printing machine should not be too fast. Otherwise. The friction of ink roller increases and the heat generated increases, resulting in the oxidation and blackening of gold ink.       When offset printing gold, the contact between acid wetting solution and gold ink will have a chemical reaction, which will darken the metal luster of the printing piece. Generally, the wetting solution containing alcohol is used instead of acid wetting solution.    After cleaning the ink bucket and roller, if the organic solvents such as gasoline and k […]
