Hi, I can giove you some suggest5ions:
1 add little more water to the emulsion so that you have a more fluid liquid where bubbles can go away easily
2 add an antibubble agent to the emulsion ( 0.5-1% max)
3 change emulsions, I use Autotype emulsion, but you have many manufacturer to try

Stir the emulsion, then let it sit for an hour to de - gas. this should stop any bubbles from transferring during the pour into the trough. If you double coat back and front, even if a bubble transfers, it should get coated out.

We have the same problem with 2 part emulsions. After mixing the sensitizer, mix well and then leave for a minimum of 24hrs. Tap the tub to bring any bubbles to the surface.

This should sort you out... Try also TEXSOL 460D from Vortex. The best emulsion on the market.
