All of these seem to have something in common with the ones you guys shared above.

Basically do I just need a really clean plate, or do the processes you shared somehow chemically prep the glass to receive the gelatin(ie.: by leaving some residue bonded to the plate that the gelatin adheres to)? Also how do these processes my friend mentioned sum up with the ones you all suggested.
You might have a look into areas like lithography or holography, where there is some experience with the coating of glass plates.
Besides the aminopropylsilane thing there is the option of forming a very thin (gelatin) subbing layer. This can be done by dip-coating. The subbing solution is made of 4g gelatin and 0.4g chrome alum, dissolved in one liter distilled water.
Drying the plates at a warm place (> 50C) will greatly accelerate hardening.
