Varnish cost reduction is the basic requirement of the printing factory

Low cost and maximum profit are prerequisites for the survival and growth of a company. Packaging and printing plants are no exception. Although light oil accounts for only 15% of the printing cost (paper accounts for 45%), according to everyone's understanding, the printing factory has never given up the low cost of glazing, and the packaging and printing plants are even more eager for light oil suppliers to have the best price/performance ratio. Provides the required varnish products.

In order to optimize its own operating expenses, packaging and printing plants are innovating the stability of production, receiving the requirements of their willing customers, increasing the production efficiency, innovating the production environment and obtaining the desired customers' products while producing high-quality products. The environmental protection requirements are the fundamental requirements of packaging and printing plants for varnish.

1) Improve the compliance of varnish for high speed printing

At present, the speed of domestic gravure printing machines is usually around 150 meters/minute, and the increase in the speed of printing presses will lower the operating costs of printing plants and increase the efficiency. Therefore, printers are eager to comply with the requirements of 300 m / min, so that the higher printing speed of plastic gravure varnish can be available soon.

2) Improve the gloss of oil

Several printing companies interviewed were eager for light oil production plants to increase the coloring of varnish, and were eager to print more jobs or a fixed number of jobs with a fixed amount of varnish to minimize the cost of printing. However, the amount of the varnish is closely related to the coloring property of the varnish. In an environment with a certain amount of ink, the higher the coloring of the varnish, the more jobs printed and the greater the profits.

3) Application of eliminated additives or application of auxiliary additives

On the one hand, printers are eager to use the varnish directly when printing, without the need to add or rarely add additives, just to adjust the viscosity of the varnish with a solvent. Adding auxiliaries will increase the printing cost, increase the preparation time before printing, waste labor, and will also affect the stability of ink, and will also cause troubles for post-press processing.

On the other hand, to be sure that the emergency agent is targeted, the auxiliary agent must be matched with varnish, the result is obvious and the application is convenient. For example, Huangshan Xinliguang Oil Chemical Plant has formulated the corresponding additives for the characteristics of the printing products of Huangshan Yongxin Co., Ltd., in which the auxiliary agents B-0020 and B0142 can effectively deal with the knife wire stain in high-speed printing, and add the B0142 number. Additives can improve the anti-static properties of varnish and do not affect the composite strength of varnish.

To perfunctory some printing plants, there is still the problem that used varnish must be stored for a short period of time. Now, many unused varnish oils that have been added with additives cannot be used in a continuous manner, resulting in waste. Therefore, the printers are eager to apply the lacquer, which can be used continuously after being stored for 1 to 2 months after being dealt with in order to eliminate the waste of the varnish and save the cost. This requires the varnish manufacturer to apply the varnish to the deployment. After the problem can not be applied continuously.
