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.

(2) It is quick to switch the hue during normal production, and it is convenient to change the production variety. It is not necessary to wash the slurry pool. Usually it only takes 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, the shortcomings of the intermittent (that is, the pool) add dye

(1) The process of colorization takes a long time. There are many transitional color papers and it is not easy to be consistent with the target pattern.

(2) The conversion of production varieties is slow, and sometimes it is even necessary to stop production for washing 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, the advantages of using new dyes

(1) The color of the paper is bright (2) It has high fastness (ultraviolet) fastness, and the long-term storage is not easy to fade.
(3) It can be mixed with water in any ratio, and the diffusion rate is fast and no precipitation will occur.
