I've got the new dragon set at 390 and 23 belt speed. It is dialed in pretty good but I'm about to run a 5 color on darks, 1000 piece job through it and see how fast we can get that belt speed while maintaining proper cure temp. I'm torn between setting the dryer to run fast enough to put the shirts butt to butt folded, or slowing the belt and lowering the temp to put the shirts side by side. On our 48" we had to put the shirts butt to butt and folded where the print was showing but now I have alot more belt to work with, and I can save gas by running the temp significantly lower with belt speed lower. It's a conundrum, good problem to have I guess.
