Re: photopolymer

Oops I meant to say more in the 300-400 ppi range.

Hi Mark,

CopyGraphics had been doing them for me at 1800 dpi (an Agfa standard apparently).

The new company I've been using has a SciTex imagesetter rendering at 2540 dpi.  It was either that or 1270 dpi...

This is not to say the screen pattern is literally 2540 dots per inch, rather, the SciTex imagesetter simply uses that resolution to create the stochastic pattern.  Under a lupe the pattern of the 2540 screen actually looks coarser than the pattern of the screen done at 1800.  SciTex stochastic patterns looks less like film grain than what Peter did for me originally with the 1800 dpi screen off their Agfa imagesetter... 


Best Wishes,
Mark Nelson
