Low cost and maximum profit are important conditions for the survival and growth of enterprises. Packaging and printing plants are no exception. Although varnish only accounts for 15% of the printing cost (paper accounts for 45%), the printing factory always pays attention to reducing the cost of varnish. Packaging and printing plants are more eager for optosene suppliers to provide light with the best price/performance ratio to meet their production requirements. Oil products.
1) Improve the adaptability of varnish to high speed printing
At present, the speed of domestic gravure printing machines is usually around 150 m / min. The increase of printing machine speed will reduce the operating cost of the printing plant and improve the efficiency. Therefore, printing manufacturers are eager to adapt to the printing speed of 300 m / min or even higher printing speed varnish can be available soon.
2) Improve varnish coloration
The amount of varnish is closely related to the colorability of varnish. In the case where the amount of ink is fixed, the higher the varnishing property, the more the printed parts, the greater the profit. The printers interviewed are eager to improve the coloration of varnish in varnish factories, eager to print more jobs or quantitative jobs with a minimum amount of varnish with quantitative varnish to reduce printing costs.
3) Application of auxiliaries or application of auxiliary additives
On the one hand, printers are eager to use the varnish used directly in printing, without adding or adding additives, as long as the viscosity of the varnish is adjusted with a solvent. Adding auxiliaries will increase printing costs, increase preparation time before printing, waste manpower, affect the stability of ink, and bring trouble to post-press processing.
On the other hand, the additives should be matched with varnish, the results are obvious and the application is convenient.
In addition, there is a problem that used varnish can only be stored for a short period of time, and many varnishes which have not been used up but have been added with additives have not been stored for a long time, which causes great waste. Therefore, the printing plant is eager to apply the varnish, and it can continue to be used after 1 to 2 months of storage to reduce the waste of varnish and save costs.
