    Low Dot Gain. Again

    Of course densities are the same. We've even double checked by measure printed sheet on other presses. Bearer pressure same also, checked that with serviceman, temps also. Btw we print with bearers being in contact, so not much can be done wrong in upper pair of cylinders.

    Low Dot Gain. Again

    Well, i'd rather not. First of all i do not want to have 8 different curve sets (4 coated 4 uncoated) - i'll loose interchangeability between presses. Second - i personally do not believe in G7 methodology. I think there is a lot of marketing and overthinking. It's more than enougth to...

    Recommendation to fix wave like ghosting for UV printing

    Describing color shift tolerance in layman's terms

    Less physical gain for sure. Now optical part is always off the charts. Also one can find that those inks one using are not quite suite for FM as pigment needs to be grinded better
