Flexo Screen Angle for Single Color

[Polyprintgirl]

We output our photopolymer plates using these flexo screen angles:
C=22.5 M=82.5 Y=7.5 K=52.5

What is the best angle to use for a non-process (spot only) single-color screen? 45 degrees is what we used in offset, any recommendations? Is it best to stick with the black angle (52.5)?

Second question:

What screen angles do people use for flexo, but on C1S Card Stock, UV inks? Same flexo angles as above?

Thx.

hi,
as long as u use 2400 DPI, mentioned screen angles are ok. you can use black angle since you are using single color.

Thanks, Arkay.

I would run a single color job at 45 degrees. That will give you cleaner looking edges on screened elements. Imagine a screened rectangle. The sides will appear to have a "wobble" to them if screened at any angle but 90 (0) or 45.

Thanks, Rich. True on the "wobble".
