International Coatings 7500 series Mixing Ink

Hey everyone,
Been having some ink trouble the past few days with some mixing IC. This job is 3 colors,(yellow, blue, green). All 3 are Pantone colors that were mixed. The blue is doing things I've never seen before. With the order being so large, we've ran it in 2 shifts. Both times we've come back to the job the ink is like concrete. The green and yellow both seem to be fine. The same blue that is mixed in the container is fine and still creamy. Could this somehow be a screen problem?

Are you printing the blue directly after a flash? The heat could cause things to gum up if there isn't enough cool down time.

Also, has the ambient temperature gotten really high in your shop lately? (I mean significantly hotter than usual)
I've seen some inks stiffen up while others didn't.

Thanks for the replies. After talking it over with people smarter than me I think over flashing is my problem. The temp in the shop is around 97 and the order I've been running is 2000 shirts. We do have a cool-down station after the flash, but the pallets still seem to be on fire even around 6 second flash times. Still a newbie at the auto game. I guess you don't know what you don't know. The fun part was it was a contract job. LOL.
Cheers

I've set up a fan after the flash (just a regular room fan on a stand) for pallet cooling assistance, being careful to not allow the airflow to hit the dryer infeed

I'll have to try that. Especially in the summer months

sounds like your pallets are to hot.

Start bumping your flash time down as the run progresses. I find that I may need a 5-6 second flash at the start of a job and as it goes on I'll be down to under 3 seconds usually. Especially in the summer.
