icc profile

One of the key factors in quality prepress making is the total colour sediment on the pages, so called “Area of Total Ink Coverage” or TAC. Maximum colour sediment is the sum of percent of which color can be made. That means that the 100% of all the primary colors in CMYK is 400% (cyan 100% + magenta 100% + yellow 100% + black 100% = 400%). Such a surface distorts a lot the print quality because the maximum color sediment in the press is caused by the paint drying, which is a combination of penetration, oxidation and evaporation. Therefore, the quality of the drying depends on the drying period of time as well as the type and quality of the substrate on which it is printed on. To avoid a print quality decline due to big number of color layers ,the maximum percentage of the total sediment is determined according to the types of paper.
