Corrugated cardboard boxes in the production process of a link is printing, is the traditional sense of silk printing. A lot of ink is needed in printing. So how can ink be recycled in order to be environmentally friendly and save the cost of enterprises?
Firstly, before adjusting ink, the amount of ink allocation should be calculated according to the paper used for printing, the type of ink, the quantity of printing and the area of the image part of the print. Paper also has something to do with it. For example, there are fewer printing inks on copperplate paper, but the quality of printing inks is relatively high. So we pour inks according to the general amount of less, and the direct relationship is the amount of printing.
Secondly, we can take good care of the products or large quantities of prints that are often printed by customers, and carefully record the ink adjustment. Sample sheets should be kept for each printing, so as to provide a reference in the future.
Thirdly, for products requiring stable hue and less ink but requiring frequent printing, we can mix more at one time. For those spot-color inks which are printed once, the remaining ink can be used to mix other spot-color inks. We should not discard four-color inks or spot-color inks after washing the machine. Let's analyze if these inks are commonly used inks. We don't want to discard it casually. It can be used as a mix in the future. When printing cartons, we often mix some water to dilute it. In this way, why don't we mix it with wishful ink? In this way, we can mix more ink to make spot-color ink. Printing products with low grade and small layout (because there may be ink skin).
Ink also has a shelf life, ink shelf life is generally 2-3 years, gold (silver) ink shelf life is 1 year, so reasonable procurement, reasonable allocation, avoid waste, so it is suggested that carton factory should purchase ink according to the printing situation of the factory, and should procure ink near the factory as far as possible, there will be a lot of spot ink, in the case of non-return, in order to avoid ink accumulation. When pressing and dispensing other spot-color ink, according to the basic principle of color matching, these ink should be used as far as possible during the shelf life to avoid waste.
