biggest donkey move ever! help!?

so i just finished printing a new batch of posters about 2 days ago and have been having some issues with my final layer drying. at first i figured it was the cold in my garage (20f at night- 50f in the day) that was slowing the drying process, but after 2 days and having only about a dozen posters actually dry i'm beginning to freak out. i thought that might have accidentally grabbed an unmarked container of plastisol but ruled that out due to some posters actually being dry. i ran a poster under a flash dryer for about 20 seconds and it definitely warped the paper and the ink was still tacky. bottom line,e i'm printing with a mix of nazdar 5600 and 9700 with about 15% thinner and after 2 days of being on paper, the ink is still quite tacky. any suggestions?

heat and air circulation- put some fans and a heater in there, or bring them into the house (and be ready for stink.) It's because the temp is so low, and if you don't have air passing over the prints, they won't evaporate off. If you were running multicolour, you might have trapped some wet ink a few layers below.

Leave a double space in your racks, the fans should be blowing through the racks to carry the solvent evaporation away from the top layer.

if you mixed in pure concentrated pigment, this might also slow drying. I used this once on a job where the client kept getting us to mix more pigment in. the stuff would not dry. We finally took it all to a friend's shop with a graphic tunnel dryer and ran it through about 3 times.

I've done this before

Get a flash dryer and put on it's side with a fan in front of it blowing the heat towards the racked posters.

Good Luck

This from far away- towards the rack!

update: thanks for the suggestions guys. got some air flow on them, to no avail. then i moved them into the basement where it is pretty warm and after about 12 hrs noticed that the posters were becoming tackier. FUUUUUUUUUUUUUUUDGE! i'm pretty sure i must have grabbed an unmarked canister of plastisol and just mixed in nazdar without thinking about it. that's the only explanation I can come up with. last night i kicked on the flash dryer and raised it about a foot and a half above my pallet and began "cooking" the prints. while they're under the flash i'll periodically wave the print about, just to keep them from warping too badly. damn... put this one down in 'lessons learned' file. MARK YOUR SHIT, JOE!

Experiencing a simillar 'lesson learned'... For the record: did your ink ever dry? I have 30 ties with tacky prints on! Cheers.

yeah, i had to heat set it. definitely screwed up and mixed some plastisol in with some nazdar. in retrospect i think the best way to have done it would be heat cure, and then flatten the paper out with a heat press.

Im a watebased printer dude.

But maybe a dehumidifier would help? It seems to help with oil painting drying.
