    Hello all
    I am looking for some feed back on personal preferences on which process you prefer run Straight UV INK OR HYBRID INK . I have run both and I am looking for what some input on pros and cons for each process . I have tested both product and have my own opinion that I will share after I get some feed back from some of you .

    Thank you

    I have possibility to work with Roland 705, equipped with UV dryer after PU1 and PU5 and of course in delivery.
    Being carton printer, we print mostly on GD2/GD3 cartons, with core from recycled paper. With goal to achieve high gloss, we would use CMYK+S1 hybrid inks + coating in one pass. On press, there are rollers for mixed operation.
    We estimate quality of ink mostly per result of interaction between ink and substrate, currently ink tack on recycled board is an issue: some inks with high tack would cause material delamination, while others will do fine.
    I am not sure, if solely ink will cause this effect, maybe printing blanked has to do something with it, but need to test and proove.
    With pure UV inks, have no real experience.

    Thanks, Janez

    Depends, the thinner you make Uv ink with a large sweep the more trouble you can have.

    Ive quickly read an article from American printer on this ink and i cant say that i have the problems they talk about, either with conventional or Uv. One thing it doesn't mention is do you have to wash the press up every night like conventional?

    Until ive tried it my opinion is, its a * Gimmick *

    Something similar to the new Pantone plus swatches....waste of time.

    UV vs Hybrid

    UV inks for paper are completely dry. Hybrid inks do some post curing. If you are running straight (not perfecting) the Hybrid is a good choice. You may need some spray powder depending on substrate and coating.
    Not all Hybrid inks are created equal.
    There could be some gloss back with UV coating, may require a test.

    We print full UV on uncoated paper (and coated stocks) and the sheet overall stays together without pick outs. There are lower tac full UV inks available, but there is a sacrifice in dot.
    Have not run Hybrid for some time. Full UV is best for us.
    Conventional inks and Hybrid inks may print a slightly better dot, and have a better water pick up window, however with the right combination of materials the UV press is outperforming the conventional presses overall.

    From what I am told, overall....those who start with Hybrid or go back and forth UV to conventional end up going full UV in the end.
