    Any QBN print heads about?

    Got a large banner I need to apply a gradient background effect to. The size of the artwork is pretty large 55cm x 200cm approx. No point in doing this is PS as the file takes forever to render.

    I can apply in Illy quickly and easily but am concerned about banding. Do I:
    A) use grey scale gradient and overprint the colour over the top?

    B) Apply a noise filter within Illy? If so how I can't find it..

    C) Just create gradients and rasterize

    I had gradients on a job I did last year. To get around the banding we set up two gradients – both to white and then overlayed one on top and set it to overprint. Depends on what colours you're using but it worked well for us in blues.

    • oh - did all in illustrator.scribbler
    • good solution for spot colors, but probably just best to set them to multiply instead of overprint in 4cduck3
    • yeah multiply would do a similar thing.scribbler
    • multiply would most certainly NOT do the same/similar thingmonospaced

    I've always used primes & multiple steps. Also, use more than just C, M, Y or K in your color and adjust then each slightly differently during the fade; say lightening the Y a bit faster than the C on a green, or vice versa.

    for example:
    C: 89% > 61% > 37% > 3%
    Y: 87% > 59% > 31% > 2%

    Then just the sliders inside each gradient to get your desired effect, i sometimes add a K on top (or below) of this as well. if you can , make the distance the gradient is traveling a prime too. So, instead of a 10 inch mask for the gradient, make it 251mm

    it may be neurotic, but recently even though some monitors showed banding on the artwork, when it came from the printer, transitions were smooth as silk (even the drop shadow i had to put under the logo) :(

    • some monitors (cheap laptops usually) are lower colour than othersanimatedgif

    I meant to add this for an easy list of primes to use as you work

    you can set it up between any numbers, you'll find this can also perform other helpful equations for your work as well
