That faded green on my sample shirt looked like a whole different color after 48 hours

I left a test print of my go-to forest green on the shop counter in Tampa over the weekend, and when I got back Monday it had turned this weird olive-moss shade. Turns out the print shop had my CMYK breakdown set to 60/0/100/20 but the ink sat too long before curing, so the yellow just soaked in differently. Has anyone else had a color shift like that just from waiting a day, or do I need to bake my samples faster?

waiting a day shifted it that hard? i've had plastisol sit overnight on the screen and come out fine, but water-based ink is a whole different animal. did you check the humidity in the shop before you left? tampa's been nasty lately, and that moisture could've pulled the yellow pigments around before you even hit the press. also, what mesh count were you using on that test print? if it was a lower mesh like 110, the thicker ink film would've absorbed way more yellow over time. i'm wondering if your curing temp actually hit what you thought it did, because a half-cured underbase can trap solvent and keep shifting for days. you got a temperature gun or did you just trust the conveyor dial?
