How it work with Thermal Plate?
The pre-bake solution's job is to project the non-image (i.e. bare aluminum substrate) areas of the plate during baking, so that they don't oxidize and lose their hydrophilicity (ability to attract water/fount on press). The hotter the baking temperature the bigger a problem this can be.

UV oven?? How does that work? Does it bring similar results to just pure heat, or do you see runs of lesser length?
HI Kevin,"Pre-bake Solution" is normally applied to a plate before it is put into a post-baking oven. Baking a plate helps make the plate coating more durable to both mechanical and chemical wear during the print run, so it lasts longer on press (up to millions of impressions).
The pre-bake solution's job is to project the non-image (i.e. bare aluminum substrate) areas of the plate during baking, so that they don't oxidize and lose their hydrophilicity (ability to attract water/fount on press). The hotter the baking temperature the bigger a problem this can be.
Normally after baking, the pre-bake solution is washed off and a normal gum (finisher) is applied to the plate too.
Keep in mind that we (Kodak) also offer a "quick bake" system that uses a combination of low heat and UV light to post-bake some of our negative plates. This uses less than half the power, a smaller/cheaper oven, and doesn't require post-baking solution or a separate rinse/gumming step afterwards.

As per u Baking solution is react with non image area, isn't it?

So we can say that it work same as gum/finisher
Gum/finisher also protect plate from oxidation. Baking solution also do same thing.
then what is difference between them??
