Continuous tone technology

Toning and dyeing can change the appearance of the paper, leaving a very deep impression on people's vision, directly affecting the product sales and customer orders. With continuous color technology you can do it in a short period of time, no matter what hue of paper or board your customers need. If you produce white paper and cardboard, it will make your paper look whiter and brighter; if you produce colored paper and paperboard, you can improve the quality while simplifying the color adjustment operation and a large number of transitional colored papers. And in a very short period of time, customers can produce colored paper or cardboard. 1. Advantages of continuous dye addition (1) Short color-adjustment time. It usually takes about half an hour. The speed is fast and the time is short. There are few transitional papers produced, and it is easy to meet the standards of the target paper samples. (2) When the normal production is switched, the hue is fast, and the production variety is convenient. It is not necessary to wash the slurry pool. It usually takes only ten minutes to complete. (3) The hue of the paper has quality control methods and methods that are not affected by night and light. 2. Disadvantages (1) of the addition of dyes in the intermittent (that is, in the slurry tank), long time of the color adjustment process, a lot of transition color paper, and it is not easy to be consistent with the target pattern. (2) It is slow to change the production variety, and sometimes even need to stop production to wash the slurry pool. (3) The lack of quality inspection methods and methods for the color and hue of paper and paperboard are greatly affected by light and cannot be managed and controlled with scientific data. 3. Advantages of using new dyes (1), bright color of paper (2), high fastness (ultraviolet) fastness, and long-term storage is not easy to fade. (3) It can mix with water in any proportion, and the diffusion rate is fast, and no precipitation will occur.
