I do a lot of rush jobs on boats. I've laminated almost immediately, high performance vinyl, HP laminate, but the jobs were small, not heavy ink. Have had zero problems.
But when I have larger letters, a van, or a printed sign, I always leave it overnight. If the letters are large, over 10", I try to leave it at least a few hours. But sometimes I have to do it right away, sometimes the tide does not wait (ha)
Most of the ones I've laminated immediately were pretty small. Maybe that's why it worked. I've been doing it for years now.
