Here’s a chart showing K percentages from RGB values of 30, 50 & 70.
That’s annoying, other Apple lists allow tiny graphics… but a list about graphics doesn’t :( Anyhow, the chart is here: <http://rgb2cmyk.co.uk/i/KGenComparison.png> That GRACoL profile produces way too much black in blue… Latest GRACoL2013_CRPC6 profile shows similar behaviour with K values in blue of 93%, 88% & 82%. That’s a whopping 26% of additional black at B70 compared to ISO Coated v2 (ECI). -- Martin Orpen Idea Digital Imaging Ltd
