 Stretch Test Correct?
I have a black body 1600 BF1 model flash dryer I am using to cure my prints. The dryer itself gets about 550-600 degrees F. About 1.5 inches away from the shirt, the shirt reaches approx. 325 degrees F in 12 seconds. Plastisol is being used, and I made sample squares and washed them last night. One set of white colored shirt, and one set of charcoal colored shirt with black ink. All the ink stayed on all sample squares, and I did a stretch test, and some of the non shiny looking prints split when pulled with the shirt fibers (which should be normal i think) and goes back together. Some of the shiny looking ones (purposely cured for a 40-50 seconds to rule out some time variables) they dont crack no matter what, but look bad. Which one is considered properly cured? |
