The Graphics Color Control Chart is similar in surface characteristics to other Leneta charts except for closer shade control in the white areas. Its printed face is coated with a clear, impervious lacquer film, similar to a plastic in printing characteristics. The unprinted reverse side is a representative litho coated paper surface.
The semi-transparent nature of printing ink applications causes the substrate color to have a substantial effect on the final color of the print. An ink color control program based on instrumental color measurements therefore requires that the test substrate itself be very closely controlled. The normal batch to batch variations in the white area of conventional paint test charts can represent a problem in that regard when testing inks. This problem is avoided by the use of Form PC-2C-S.
