Have folks had any problems with using a traditional Seal heat press and Colormount tissue when attempting to mount prints that have already been sprayed?

I'm using Canson Baryta or similar, and mounting to 8 ply museum board. Done it before with prints that were not sprayed and realize that just spraying them after mounting would make most sense, but have some good copies already sprayed that I'd rather not re-print and re-spray.

Thanks a lot
