LPI, mesh count, and degrees.
I'd like to print some gradients on fabric.
After days of search I've understood how to print gradients (at least on film)...but I need the help of any experienced guy to understand better.
I created some gradients with spot colors, then in the Illustrator printing dialog I selected just the gradient channels. Here I should set the angle and the lpi of the channels but I can't understand what to insert. However I printed the output to the Adobe Postscript Printer, having a file with .ps extension. (I've installed the Adobe Postscript Printer previously)
I installed Ghostscript and then Ghostview (you need Ghostview to open and use Ghostscript).
With Ghostview I opened the file, made by 2 pages, because 2 were the spot colors of the gradient. I exported one page in .eps, then the second page too, so I was able to mount in Illustrator all the plates for the film.
Now I'd like to know if there's any LPI / mesh count table to follow for a correct print and to avoid the moire effect.
I'd like to know also something about the degrees of the plates: how can I understand the right angle?
Thank you all :)
