| I know how to do this for the most part. I used to do this in school. I know to use high optacy plastisol inks and all that. My problem comes in with flash curing. How am I going to do this with out buying a $400 flash curing unit. My sales wouldn't make up for that for an entire year or so. Is there anyway to build one or get around this some how? |

You can try using a heatgun(ie. paintstripper). They do work, as we use them in the shop from time to time(usually when printing on nylon where a flashcure would melt everything).
It's a lot cheaper than a flashcure system. |

| A friend of mine actually set up a rig where he had four heat guns pointed downward through a piece of plywood with hole drilled in it for the barrel of the guns. He had them all rigged to one switch to power on/off and that worked pretty damn good. |

| Cool, I thought that it would work but wasn't sure about it. How long should I use a heat gun over a print? I am not worrying about burning it I just dont want to under cure the ink. |

Do some experiments. Time your curing, then grab the print between your fingers(after pulling it off the pallet) and give it a firm tug. If it cracks, it ain't cured. If it doesn't, your golden.
Another little rule I go by when using a gun is "if it smokes, it's done"...
Just experiment for yourself. Good luck. |

| haha, I like that rule. I would love to do the least amount of expieramenting as possible. My budget doesnt allow for too much slack. haha |

You can also try to get a used unit off of ebay - works much better. Sometimes you can find the element and then fab a stand for it.

What about these inks that say heat at 300 degrees for three minutes? Both of the plastisols in my dickblick catalog say this. Would a heat gun work for these?

300 degrees for 3 min??? hmmmmm...
I have a flash unit & a conveyor dryer and have never cured anything that long. A 100% cotton shirt usually cures for about 60-90 seconds max - depending on the inks.
Anything like 50/50, poly, mesh usually cures faster. Not sure that a heat gun will give you the even coverage you need. I've know people to cure shirts in the oven before but that's flirting with disaster!
