In 4C printing, the challenge is to find the right dosage for the required ink application. Ink application of over 300 %, which has a negative influence on printing results especially when waterless presses and printing couples without ink zones are used, are not unheard of in everyday use. Past experience shows that an appealing image quality, which reduces ink consumption, the number of waste copies and drying time to a minimum, is only achieved at a value of less than 240 %. To ensure that you are always on the safe side here, ppi offers you a solution for automatic ink reduction which you can integrate quickly and easily in your PostScript or PDF workflow.
