Looking for double sided paper for doing book dummies. Needs to be smooth, luxurious, but not too thick. The paper Aperture magazine uses is just right. I print with a 3800, on baryta papers for photographs, so something that could use PK ink would be great, what with the waste associated with switching to MK and back. Tried Red River Zeppelin, and Adorama's Projet, both semigloss or luster. Both are too thin and buckle too much, and the surface is a bit mottled. Very smooth matt would be OK, but would like to resist using the MK inks if possible. Ideas? Thanks!
