Large Greyscale and Colour Separation Guide
Large Greyscale and Colour Separation Guide - quality and accuracy in image reproduction
The Large Greyscale and Colour Separation Guide is a Q14 equivalent quality control device for photographers, printers and other colour professionals. The twenty-step Greyscale offers an accurate, easy way to compare tonal values in an original image with its reproduction, while the set of eighteen colour patches (two saturations of nine colours) allows users to compare the colour of their subject with known printing colours.
Colour Confidence recommends users replace their Large Greyscale and Colour Separation Guide on a regular basis to maintain accuracy.
