banding in halftones

Living tees · February 17th, 2011, 11:47 AM

we get them sometimes. what can we do to be more consistant

it could be:
You are printing at 45 or 90 degrees?
You are printing too high a halftone for that printer?
Your printer is banding?
Any thoughts?

we are printing at 45 degrees. the printer is a xante screenwriter 3. lpi is 32 to 45 on 1200 dpi. does this help?

If it's a laser printer it could be the cogs driving the film?
Does it happen on plain paper?
Can you change the 45 to 22?

Have you tried adding about 5% noise to the blend?

Should help..

I'll try the 5 , thanks. I can't see it on paper but I can't see it on velum until I burn it and it's in the screen
