How long do you want to leave Glossy inkjet photo paper dry?
I just printed out a bunch of photos with HP Premium Photo Paper – Glossy Inkjet – The paper is very glossy, and I know it is not naturally dry enough to put in frames now. How long should I wait before I excised the pictures and put them behind glass?
I would wait at least 24 hours, then do the smudge test, lightly run your finger over a test photo and if it still seems tacky let it sit for another 24 hours. After that you should be good to go.
