Ink grading plays a crucial role in the smooth printing process. What preparations do you need to make before printing the ink?
1, the workplace
It is best to have a dedicated studio to focus the coloring staff, to have ventilation, to remove solvents, and to set up illumination that is similar to the sun before noon. There should be a variety of basic inks and standard samples in the color mixing room. Keep a certain temperature and have large windows.
2, illumination light
The color is adjusted in a certain light, and the color changes when it is changed to natural light or other light conditions. Therefore, this factor must be taken into account when grading, and the following light sources are usually used.
1 natural light
The northern window light in fine weather is the best, the sun can't be directly injected, but the effect is not good in the evening.
2 standard light source
Compare colors in a box-like standard light source unit, independent of the surrounding environment.
3 fluorescent lights
Fluorescent lamps, especially those with comparative colors, are not allowed to be affected by the surrounding colors and other light, and the walls or surrounding facilities are painted gray or with special barriers to block light.
3, coloring tools
The following tools must be prepared for color matching:
1 ink knife, used for ink adjustment;
2 ink scraping, color development;
3 scraping paper, ink bearing;
4 viscometer, viscosity measurement;
5 stopwatch, for viscosity measurement;
6 scales, a small amount of weighing;
7 color bar NO6 or NO7, the same as the print with 32~35μm plate depth.
