Colors bleed when curing in oven

[Rooger]

Just starting to paint lures using Pro-Tec powder paints. I just had a couple of spoons bleed the colors into one another when baking in the oven. I went with the recommended 350* for 20 minutes.

Naturally, I didn't like the way they turned out so I stripped the paint and painted them again. Any suggestions on how to prevent this next time? Lower heat; less time? Both?

Thanks!
