Both coloring and dyeing can change the appearance of the paper, leaving a deep impression on the human vision, directly affecting the sales of the product and the order of the customer. With continuous color grading, no matter what color paper and paperboard your customers need, you will do it in a very short time. If you produce white paper and cardboard, it will make your paper look whiter and brighter; if you produce colored paper and cardboard, it will improve the quality while simplifying the coloring operation and a large amount of transitional color paper. And in a short period of time, it produces colored paper or cardboard that is satisfactory to customers.
