For the print operator, the printability of the ink is good and can be put into use once the lid is opened, which of course is the most convenient and convenient. However, due to differences in temperature and humidity in the printing environment, characteristics of printing materials, and different printing process conditions, such as the paper's moisture content, PH value, printer speed, and overprinting methods, the ink types are varied, but each The proportion of pigments, binders, and fillers used in the ink is almost constant, and the printability requirements for various conditions are not always satisfied. Therefore, from the perspective of improving printing efficiencies and quality, according to the changing printing conditions, proper addition of additives in selected inks is beneficial to ensuring normal printing. 
1 î€ The role of varnish The commonly used varnish has No. 6 and No. 0. No. 6 varnish is used to increase the fluidity of the ink, improve the transferability of the ink, and reduce the concentration, viscosity, and drying of the ink. No. 0 oil has a larger viscosity. When the viscosity of the ink is insufficient to cause the ink to be printed or the ink is not good, the proper amount of No. 0 oil is loosened and added to the ink, which can increase the viscosity and adhesion of the ink.
2 The role of deodorizing agent Detackifier is a kind of wax-like paste mixture, texture is loose and lubricated, the amount of ink added can reduce the viscosity of ink, reduce the paper pull paper hair, powder off the ills, and can improve the cloth ink Evenness. 
3 The role of anti-sticking agent Blotting is a common fault in the color printing process. Adding an appropriate amount of anti-sticking agent in the ink can prevent back-smearing of the printed sheet stack due to the ink layer not drying, thus ensuring product quality. 
4 î€ The role of additives It is a white transparent paste-like substance, the amount of added ink after the elimination of paper lint, powder off phenomenon, to prevent the layout, blanket dust heap blister disease occurs. 
5 The role of light dispersant The light dispersant is an oil-like transparent material with good gloss and good printing performance. After adding color ink, it can dilute the hue of ink printing process effect. 
6 The role of anti-friction agent It is made of polyethylene wax and high-boiling point kerosene into wax paste, in the printing ink by adding 1% to 5% of anti-friction agent, can improve the printing ink layer wear resistance, and can Reduce the viscosity of the ink to reduce the chance of sticking. 
7 The role of anti-drying agent The anti-drying agent can inhibit the oxidation and polymerization of the ink after adding the ink and slow down the drying of the ink conjunctiva. Spraying the anti-drying agent on the ink transfer roller, such as the ink roller, can play a role in stopping the drying and bring convenience to the printing stoppage and printing.
8 The effect of desiccant The desiccant is divided into two types: white dry oil and red dry oil. Red dry oil is a desiccant based on cobalt naphthalate. It is a purple-red paste liquid and is suitable for adding in dark ink. Its dry form is mainly based on the surface of the ink layer. The dosage is 1%. Between ~ 2%. White dry oil is a mixture of cobalt, manganese, and lead metal salts, commonly known as mixed dry oil, with a full-drying role inside and outside the ink film, the dryness is not strong red dry oil, but the drying effect is better, and It is white translucent and has no effect on hue after the addition of light ink.
9 The role of bright oil In addition to gloss oil used in polishing, relief printing ink in place with the right amount of bright oil, can increase the ink's fluidity, is conducive to uniform ink, and can greatly improve the printing ink film The brightness, so that the ink layer has a certain degree of wear, light and prevent the fading of good effect. Due to the bright oil conjunctiva block, the drying speed of the printing ink layer is also increased after the ink is added. Therefore, this condition should be fully taken into account when the ink is transferred. 
In short, the ink composition and auxiliary materials constitute the basis for inks and imprints, understand and master this knowledge, understand the performance of inks and methods of use, improve the printing efficiency and product quality, and avoid blindness in the operation process. It is of great significance.
