Ink limits and perceived print quality

With high speed continuous forms ink jet printers moving into the offset market, new demands are being placed on the printers, ink and paper combinations. Traditional ink limit processes perform adequately as long as ink limits are greater than 200 %, however, with thinner papers, issues arise that push ink limits below 200% affecting secondary colors significantly. In this paper we will show the effect of ink limits on primary and secondary colors, and results of applying a method balancing color fidelity to maximize overall perceived color quality. We will show results of color measurements as well as this method applied to typical jobs that include text, lines and pictures.
