How do I increase density (ink deposition)?

    Printing some eight foot electrical sign faces onto 3850. Usually we set the machine to "return to point of origin after printing" then hit print again.

    This allows an extra "coat" of ink to increase the density of color because they're back lit.

    This method also allows the printed image to get off about 1/16" in the eight foot length.

    Can I artificially somehow change things so that we lay down more ink with each head pass? Thus eliminating the second printing?

    Rookie question probably but I'd appreciate any help possible.

    Somewhere in the RIP there will be a setting for multiple ink layers, it may be called something slightly different depending on the RIP, but it'll be there.

    Ooops, sorry. Guess that would be helpful.

    By assigning spot colors to the design (vector only) through Roland's Color Swatch Library, you can change the color call out for that particular color within the rip.

    3850 Double Strike?

    Sorry to dig up an old thread but I have my first printing job coming up on ORACAL 3850. Do you need to double strike it (Over Print)? Or will the default profile I downloaded from ORACAL have this turned on in VersaWorks?

    Sorry for the newbie question, but I don't want to waste a wack of material and ink when I can ask some folks with experience :thankyou:
