    Standard or Approximate Densities for GRACoL 7 Process Inks ?

    G7 densities and dot gain values that you may see published are only 'informative'. The process ink target values for solids are ISO-specified L*a*b* colors: K = 15/0/0 C = 55/-37/-50 M = 48/74/-3 Y = 89/-5/93 Nominal 'informative' TVI values for #1 and #2 coated are: K = 20% C = 16% M = 16%...

    Akiyama Press Testing

    One of my printing clients asked me to print a test form on a used, rebuild press he was buying. The rebuild shop did a good job of setting up to run the test. We had pretty good, representative sheets, IMHO. Everything looked pretty good until we measured 50 consecutive sheets. We had fairly...

    UV coating adhesion problem

    We've been doing strike-through coating on UV presses for more than a year now at several printers; it works very well. Specifically, the adhesion is excellent: passes the 'ANSI Scotch-tape test' with flying colors. We'd like to use printers that don't happen to have a UV press. They print...

    Unwanted Absorptions

    Hmm....I don't think so. What I assumed they were referring to is 'hue error' and 'gray value'. I've been noodling around with the idea of wide-gamut (4-color) inks. What I've seen called 'wide-gamut ink set' has very 'clean' magenta and cyan colorants which I assume would give very low...

    Unwanted Absorptions

    I read this today. It sounds counter-intuitive. There is one highly advantageous aspect of the so-called “unwanted absorption”: the nonlinearity of mixing produces a gamut for subtractive reproduction that is wider than would be the case for ideal, non-overlapping pigments. Has anyone seen any...
