Well, my experience has been different. Yesterday I painted a frame. Today I applied varnish transfers. Tomorrow I'll clearcoat it. All with Dupont Imron. NO force drying used.
I've used varnish transfers from Italy, Japan, Britain, and America.
Same results. I'll bet lurker Brain will say the same.
I've put water tranfers on with varnish when I wanted them to stay put...
