I'm using Epson Presentation Paper Matte which is 102 gsm, 4.9mil thick - so it's really almost like regular copy paper weight, (unlike the 'premium' or 'ultra premium' ones which are thicker.

I choose this thin paper because I'm using the prints just as proofs to tape in a book dummy, I wanted the most lightweight paper possible – so I was prepared for the weak blacks, but what I'm seeing (and I don't recall this being such as issue with the red river lightest weight matte paper) the prints that have darker tones, even after over 24 hours of open air unstacked drying are very wrinkled and curly.

Just wondering if anyone else on here has used this particular paper and found a way to deal with that?

Thanks
Chester
