Revisit your exposure times. Make sure you are getting complete exposure. Ensure that your screen-room is at an acceptable humidity level. The emulsion layer needs to be below a certain level of humidity to obtain proper exposure. Next, contact River City to check on shelf life of your emulsion remover and also if it is the best chioice for PP emulsions. Look at your on press wash or screen opener and also your ink remover/degradent. PP emulsions don't get along well with most solvents.

We use CCI Envirowipe. Works great for all PP emulsions unlike standard solvents and other cleaners.
