Please don't laugh but they went through our Vastex EC 54" with the scrub air on, 3' chamber. It was sloooooooooooow, it took a little less then an hour to do the job. When they came out there was still a faint smell of the discharge so they went through a second time. Yes I am looking for another larger dryer to be a little more efficient. We ran the white/yellow job earlier this week through our Max Cure, 5' of heat. For that one we just slowed the belt speed down a little.
We have the same issue with most customers wanting light colors on dark shirts, surprised how many people want black for summer events. We do a quarterly order of a six color+UB on black shirts. No mater what we tried the end result feels like a rain coat. This is what pushed us to start testing the Discharge and WB. We are redoing the art work now and hope to run that job all WB.
