Hi, everyone!

I am making prints using Epson Ultra Premium Luster Paper. The backside of the paper is quite slick and doesn’t take a lot of archival pens well. I’ve tried a variety of archival pens (Mircon, etc.) to no avail. Some non-archival marker options (Sharpie, Copic, Staedtler Lumocolor, etc.) work okay, but they’re not archival/acid free. Sakura Pen-Touch works great, and it is archival, but it is a paint-based marker (with a marble in it) and it lays down paint thickkkkk.

Few questions:

• Has anyone had success finding an archival pen/ink that works well with this stock?
• Does archival even matter in the real world?
• If we shouldn’t bother signing our prints (as some have suggested on this subreddit elsewhere), what else might one do to add a special touch to a print you’re trying to sell?
