From sample to colour – A job for specialists

Depending on the area of application: Commercial printing, Packaging printing i. e. BoFood® MH for indirect and BoFood® Organic for direct foodstuff contact, the purest ink PURe® and UV, UV LE / UV LED.
The customer's wishes.
An end customer's colour sample arrives at Epple. This can be in the form of a printed product or even an actual physical object. Based on the sample, the colourists at Epple determine the corresponding colour tone for the desired substrate. Branded companies generally work with a strictly defined colour scheme (Corporate Identity), in order to design a coherent brand environment.
Quality and Recipes.
Using the XRite eXact measuring device, the colourist measures and interprets the sample's colour spectrum and the XInkFormulation software calculates the recipe of the respective offset printing ink. However the visual judgement of the colourists is demanded for some applications that are problematic for the measuring technology. The trained eye of the colourist is the final decisive factor before release of an ink recipe.
