1. Re: Banding on Transparent Gradations & Dithering

2. Re: Banding on Transparent Gradations & Dithering
Canned Pug Feb 12, 2011 6:23 PM (in response to BobLevine)I could do that, but I don't understand why it's there at all?? I've
printed other artwork done in the same way with great results....don't
know what the common denominator is...Thanks for your input. If i knew
why I could fix it...

P Spier Feb 13, 2011 4:43 AM (in response to Canned Pug)The differences in the colors and the distance over which you spread the gradient can influence wheterh or not it exhibits banding.

4. Re: Banding on Transparent Gradations & Dithering
Canned Pug Feb 13, 2011 11:33 AM (in response to P Spier)Yes, maybe I've been lucky up til now...I'm also wondering if applying a gradient several times over one area in different directions could be the problem as well, but the area is asymmetrical...
I'm doing a transparent red-to-clear gradation. I tried the noise but even a little bit destroys the color, and if I do it enough to get rid of the banding, it becomes, in effect a grey-to-transparent gradation and very grainy to boot (70%, Uniform, Monochromatic).
Ugh. If I make it a less intense, ie lowering the % of the layer it's on, it is less noticeable, (which I don't know if it will also show less in printing, or not. Actually the banding may not show either, because I hasn't on my own printer). Or I could take a Gaussian Blur to it, enlarge it to go past the areas where it needs to be tight up against some edges, and erace it back.
Some of the forums were talking about playing with 16-bit and 8-bit and OpenGL turned off, etc( which I couldn't find in my PS (CS3) preferences anyway to even experiment with) and I felt I was sinking down the rabbit hole. I haven't gotten any work done for the last 2 weeks in trying to ready my work for print. So at this point my hair is tearing out in patches where it hasn't fallen out with stress!
Double Ugh.
thanks for all the feedback...I have tried all suggestions.

Canned Pug Feb 13, 2011 11:38 AM (in response to Canned Pug)As an addendum, all this has happened since I:
1. calibrated my monitor
2. started working in CMYK and otherwise fooling around with file color profiles, monitor color profiles, Blurb.icc color profiles, converting color profiles etc etc etc and letting the app handle the color instead of the printer.
Whereas before I was a happy dumb camper.
