 Re: How to alleviate the crosshatching of the screen when printing a half tone gradient
The original post states that it prints that way in paper proof. If it is moire than it is not the screen angle. It is the screen mesh count. A good rule of thumb is the lpi of the halftone x 4 plus one. Hence a 65 lpi x4 is 260 mesh plus one 305 mesh.
Further the angle can make a difference but then again so can the shape of the dot and further beyond that you can mount the screen on the frame at a 22 degree angle if you really want to get down and bad with yourself.
Another instance when I do 4 color process my angles most of the time are cyan 22.5, magenta 52.5 yellow 87.5 black 87.5. using an eliptical dot.
If I am dropping in a spot color the angle is set to match the angle of the color closest to the spot color ie orange spot could be either 22.5 or 52.5 degrees. |
