I'm not familiar with the particular emulsion but here are a few pointers....

Diazo based emulsions....

1. Only last 4-6 weeks when sensitized with diazo
2. are easier to washout than non-diazo photopolymers
3. can be more forgiving to expose with lower grade exposure units

Pre-Sensitized Photopolymers...

1. Last up to 1 year in the bucket
2. coated screens can last up to 1 month before exposure
3. usually better resolution for fine lines and halftones
4. more difficult to washout the image....get a pressure washer.

As far as the ink goes.....I have never heard anything good about International Coatings brand. You might want to do a search of the boards before you invest in a full kit. They might be ok....but I've never printed with them.
