Kraft paper is widely used in envelopes, hand bags, paper bags and other applications because of its good logistics performance and flexibility.

However, if the color of kraft paper is uneven, its quality and sales difficulty will become extremely difficult. So what about the unstable color of kraft paper?

According to the application requirements, the actual colorimetric examination is adopted: because the color of kraft paper will be different due to the influence of light source, light angle and human factors. At this time, it is necessary to dye according to the actual color of kraft paper. If the printing and dyeing wants more red adjustment, it is necessary to use uniform color space for color matching and add red dye. This can effectively reduce the color deviation.

When adding dyes, the metering pump is used for metering: the traditional dye sizing system generally adopts continuous sizing, and if the amount of dyes is small, it will affect the uniformity of color matching. However, if the dye is added by metering pump. On the one hand, it can avoid different dyes dissolving together to produce lakes, so that the dyes are uneven and waste dyes. On the other hand, it is convenient to adjust the dosage of a certain dye separately.

Multiple color matching test: multiple repeated color matching when the slurry is dyed. This can make the dyed color more uniform and bright.
