Set it at 61
I was always under the guise of the same angles being for simulated process. I've seen better results with CMYK at different angles.I've found that a set angle of 22.5 for all screens works great. Correct me if I'm wrong, but I was always under the impression that different angles for CMYK was an outdated concept?
Interesting. I have always used the same angles 27.5Different angles allow you to achieve a wider variation of colors and subtleties in your image. The same angle dulls colors because they stack up. There is a reason for the rosette pattern, it allows the colors to work in a pattern which layers the edges of dots in a way to mix secondary and tertiary colors.
Conventional offset angles are adjusted in screen printing to help with the reduction of moire patterns.

Cyan 55.0 22.5
Magenta 55.0 52.0
Yellow 55.0 82.5
Black 55.0 82.5
Even though there are various angles listed, many different combinations will work. If you want to simplify it, start with black at 45 degrees. Then go C M Y, adding 30 degrees each time. Black 45, C 75, M 105, Y 135. I listed some earlier in the thread that works as well.hi
i am trying to output a jpeg image as 4 colour process in illustrator, we output the films but are getting a bad moire pattern..
for all process jobs we put these on a 120 mesh and i output them as 65lp as this is the lowest setting illustrator allows me.
what screen angles do i need to use, im confused as there is so many.
