| I�ve noticed that some prints that I`ve printed on t-shirts are not holding together when I�m streching the shirt. Am I using to little heat or to much heat when running them through my heater (oven)? Those shirts have been flashed dryed also cause they are multi colors on black shirts. |

| most likely you are under-curing them between colors, if you are using plastisol inks, the average time they should be under the flash cure is between 35-50 seconds, hope this help. like the average time it takes to put on a shirt, line it up, print your color then rotate, or when the shirt under the dryer begins to smoke lightyly |

| Ok, but isnt just the flash cureing for not letting the colors smear when printing multi color and not for the final cureing of the print. The final cureing is done in the bigger oven right? |

you can do full cures w/a flash unit but its slow. Also, if you have wooded plattens its best to take the shirt off the press and have a full-cure area as the extended heat could warp your plattens over time.
As for times - flash 8-10 seconds per color and full-cure for 60 seconds. Depending on your oven features (belt speed, temp control, etc) that can change a bit. Lower end ovens w/no temp control might require you to run the belt a bit faster since the heat is always constant.

| But if a print is cracking is it casue it got to little cure? or to much? can you cure a print to much? I heard people tell me that you cant over cure/heat your print. Is it so? |

oh yeah - you can 'burn' it - but its the shirt that burns in the dryer (there's a trick to getting the burn out as well).
If the ink is cracking then you are not curing it all the way. The ink should be rubbery and solid when fully cured and not crack at all. depending on the ink thickness and the apparel (t-shirt, girlie ribbed tee) this can vary a bit but 9.9 times out of 10 cracks mean under-cured ink.
