insignia, what don't you like about the Postermax specifically? Sihl Trisolv was the first
paper I tried years ago, and I never could get satisfactory results from it. It looked great coming on the printer, but half an hour later it seemed as though the inks "soaked into" the media leaving a washed out print. I recently started running the Postermax with much better results. Although, I have to print it at a high resolution which is really slow. I'd be interested to hear your opinions/results on both materials.
