A hair blow dryer is a must in our shop, we use it almost every day.
Our screen process:
-Expose
-spray out
-squeegee water off (window squeegee)
-compressed air to blow out water from open mesh areas
-wipe dry with cotton shirt
-either blow dry with hair dryer or if were not rushing outside in the sun
....and yes sp1400 is the best emulsion we've found so far for DC printing nothing else comes close!
