Taking it back to basics we learnt about the old school techniques of the industry. How you use to cut out every individual letter , lay out the grids an guides an stick them on one by one. How choosing a colour was a very specific process, which comprised of CYMK (cyan,magenta,yellow,key), different from the old RGB.
CYMK was the four colour process, that allowed you to get the best quality from the printing process along with being the most cost effective.
Print Control Strips in printing are used to help colour control through the whole process of printing and at the end we have a quality printed product.This control strips are usually put across the edge of the printed sheet containing various test elements for each of the four colours.
