[QUOTE=zooskifilms;5392]The lines don’t appear as sharp as I would expect. Seems like the ink is spreading farther than it should (dot gain?).[/QUOTE]
I hesitate to intrude into this thread, but there is a very simple and embarrassing mistake that I once made, which had pretty much these symptoms. And that was to print on the wrong side of the paper. Are you sure that you’re not doing this?
With regard to the paper curling, I had this problem years ago when I was running piezo on an 2100/2200 on EEM and the old-style non-transparent cartidges. Nowadays you could probably get a custom profile made that hopefully would deal with this issue. What I did back in those days was to print at 1440 rather than 2880, and to make some compensating adjustments to the supplied curve. I had to do this in Excel and it involved some trial and error, but it worked fairly well. Jon thought I was a little crazy, as piezo is supposed to work out of the box, but what’s the alterntive, other than going to a heavier paper? If you’re interested, I can see if I can find the details of how I did this.
