New Problem, never seen it before. top colour cracking when pulling off platen

[Printficient]

Well after a phone call to Sonny/Printficient (Thank-you!) we seem to have found the culprit!

Pallets were sporting a coat of Sprayway Fast Tack 384 Super flash mist from the previous run of tech shirts. not a ton, and not enough to cause a problem with pulling the shirts off, but basically may have been causing some sort of chemical/offgassing thing.   Fresh pallet tape and a change to Sprayway 83 Web adhesive cured the problem, even though overall tack wasn't reduced, in fact it was probably increased.

We ran the job (96pcs.) and flashed after the maroon, but after that I left it set up and started to eliminate potential causes as I sure didn't want to run into this under a tight deadline.

Glad I could help.  Just one of the many wacky things I have had happen over the course of my printing career.

Dare I ask if the problem resurfaces using a water based tac like Textac?

I have had the same thing happen a few times and it does seem to alway be red ink for some reason.

I can't tell you, I had some and was going to use it, but went with the web-tack instead. We often switch up cotton/fleece/triblend and tech shirts all day long and I've found water based tacks don't perform as well as we'd like on broad varieties of fabric.

We did throw some Cool Grey 11C on the maroon screen to see what happened, and it printed and pulled just fine. It seemed to be the red/maroon ink and flash/mist adhesive combo that was the problem. Sonny did predict that due to the difference in pigment properties between red and black/white.

Just wanted to chime in on this since I just had this issue a few days ago.  Was running about 280 units on a 5 color print, last color down was dallas green.  The first few I had the "cracking" just on the Dallas section of the graphic.  After a little bit of trial and error decided to double pass the green and that solved the problem right up, shirts still looked perfect with the double pass, but for some odd reason the issue disappeared.
