After 6 hours or so paper is still tacky
It has been my experience when ink doesn't dry almost instantly, there's a chemical incompatibility either in the coating or the chemicals of the ink.
That paper makes my trash pail.
I have had paper where the ink pooled on teh paper, and never dried. In that case it was wrong ink. for the paper.
All the papers that I have ever used, dried instantly.... that is not the same as "curing".
Some papers require a curing time for the final colors to set. Some took 24 hours to do that.
The ink is dry, but time is needed for final color setting.
