    might seem too obvious but I would also ensure you are not putting down too much ink on the first pass and/or unbalanced ink/water thereby causing emulsification and an ink film that will never dry!

    You need to go to a high solids, low petroleum solvent type of ink formula. AS a general rule of thumb for the press person, the ink should NOT STAY OPEN any longer than "8" hours in bulk.

    Usually quite an easy fix via the ink medium. D

    An old school solution was to clean the cylinder well or even polish it then rub it down with fountain concentrate (not solution). Repelex was always the best.I'm not sure if that is still sold.

    First thing that will solve your problem is better ink. If that's not available a simple wipe of your impression cylinders with a good liquid silicone such as Prisco Slide will help quite a bit. You should also consider getting rid of the IPA at your next roller change.

    So for you orientation plays no role in prepress?

    Clarification of the problem?

    1) Do you have assisted drying at the delivery end of Press e.g. I.R.?

    2) If not, by extended drying you mean longer time interval between printing 1 side and back-up?

    3) Are you using conventional Oxidation type litho inks?

    4) Are you using Foreign/Indian manufactured Inks?

    5) Are the Plate/Blanket/Impression-Paper NIP pressures correct?

    Finally, in my opinion the problem lies with poor Ink/Paper relationship, e.g. Ink Absorbency


    Regards, Alois

Print Embellishment Goes
Straight To The Bottom Line

InfoTrends reported that interviews with more than 100 print customers demonstrated an appetite and willingness to pay premiums of 24% to 89% for special effects, over CMYK-only printing. They also indicated embellishment could apply to a significant portion of their work. Embellishment options can include hot foil stamping, spot gloss UV, embossing, debossing, letterpress, diecut shapes, lamination, duplex, triplex, gold foil, silver foil, copper foil, white foil, black foil, clear foil, etching, and laser cutting techniques.
