Now since we are printing on a finished envelope, we do not have any space to print the color bar, and hence the ink adjustment has to be eye balled by our press operators. For matching colors we need to be able to print a color control bar on the printed piece and then it is scanned by a spectrophotometer which checks for the color density and automatically controls the inking system on the press. Color Matching: It is very hard or sometimes impossible to match colors.
This allows us to offer the lowest prices but does have some limitation when printing in full color.
