Thanks

Charlie Taublieb said this recently at a seminar I went to:
230 mesh screens, 45 lpi, 61 degrees, ellipse dots..  for everything... even 4cp(!) work.

Separation Studio manual says 230 mesh screens, 45lpi, 22.5 degrees, round dot

I've found good results with the 230/45lpi/22.5/round combination

For detailed artwork with halftones, I recommend:

55 lpi
67 degrees
ellipse shape


305 mesh screens

22.5 and 67.5 should result in identical results (splitting the angles of the mesh to prevent moire).  The LPI should be determined by the mesh you will be using, and your ability to hold and print smaller dots (based on your exposure setup etc).

Charlie has been saying that for 20 years now..  ::) 

The correct angle and dots are the ones that work on YOUR screens. Make some test films with varied DPI and screen angles, then expose on each mesh count you have then print them. You'll see very quickly what dpi/angles work and don't work.

I've had way better results with a 25 angle vs the 22.5
Same holds for dpi as I found sweet spots in odd numbers.

With so many mesh counts and thread microns available, the old stand by numbers are just a guide to get you close. It's up to you to nail it.

65 lpi, 22.5 lpi..... Look at our prints in the gallery, if done right you can run that all day long on any job
