In the film production process, often to the use of ink on adaptive adjustment. In order to adapt to different products, different paper printing needs. Suitable for printing ink to adjust. Is to be achieved by adding proper auxiliary material in ink. Because the auxiliary material is not the same understanding or prejudice, so. In the actual production is likely to enter some "error", has not satisfactory results.

One, complete with adhesive instead of inking oil

In the production process. When printing large area ground version. Ink in ink roll transfer process is not easy to be beaten or paper "wool", printing rough phenomenon. Is generally caused by high viscosity ink.

Go to the adhesive and inking oil can reduce the viscosity of the ink, they are not exactly the same. Go to the adhesive to reduce ink viscosity at the same time also has the suppression of ink drying effect and reduce the focus on the nature of the ink layer and paper sticky. Ink in the ink, which can reduce the viscosity of ink and ink increased liquidity effect. The ink drying speed is not very obvious influence but. If in the printing ink blindly add excess adhesive to reduce ink viscosity, it is possible to create "print out stem" or ink layer "powder" phenomenon. When adding to the adhesive should pay attention to "quantity", must not let down. Keep it in proper ratio within it. At the same time and increase the amount of desiccant. In order to avoid the adverse consequences caused.

Two, with white ink as diluting agent

Individual color ink is added to dilute the agent as a light coloured ink in the original ink, the agents should be diluted with colorless and transparent properties. Light and rcheulishvili oil are the ideal blunt spilled agent, it has does not change the original ink color but can change the role of the original ink shades. If the white ink as dilute agent use. It is improper. For white ink with a white hue, it will change the original ink hue enables the original ink tends to be white jade ink rather than as a light coloured ink. This is contrary to the operator need light ink intent. And in the process of offset printing. If the ink in white ink composition too much, because of white ink pigment particles than the major, in ink conveying process will occur pigment particles to stack on the printing plate or blanket. And cause the ills of the western blot.

Three, do not distinguish between the adhesive and adhesive difference

The ink to join the adhesive, to prevent or reduce the paper on the back table sticky dirty problem after printing. To Gu Jing is to reduce ink viscosity, it is mainly to play its role in the printing ink transfer process in. If you do not distinguish between the two are confused, it is likely to produce other problems.

If in order to prevent the paper on the back table printing ink sticky dirty and in ink add to adhesive, adhesive "stem" nature will enable printing ink layer drying time prolonged and counterproductive to the surface of the paper and are more likely to stick dirty. On the other hand, if in order to reduce in the process of printing ink viscosity and join the more the antisticking agent, it not only can not very well to viscosity reduction. Will make ink "rough". To make it lose its luster and affect the quality of the product.
