Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
That's our Sonny for you!
Alan Singer did the R&D on this. I spoke with him about the specs. He basically said do not over flash and keep oven temp at 330 degrees and all is well. To adhere to nylon without a catalyst requires a cross link temp in the mid to mid/high 200's. Do this and there are very few if any dyes that would migrate on blends. Nylon does not bleed so the low temp cure is so the substrate is not damaged. I have always said that if you could truly dial in your dryer (gas preferably) and keep the garment to below 330 degrees any white would be bleed resistant as the dyes would not migrate. What we do now to inks is horrible. A slow belt dryer set ro 320 degrees is the way ink should cure. A fast belt high temp dryer shocks the ink and that is bad. Same with flashing. Quartz bulbs that are not adjustable are the worst thing out there for the health of inks. A flash of 5 seconds is a production rate of 720 pcs per hour. A 4 second flash is 900 pcs per hour. We are overcooking our inks in all phases. Problem with a print on darks will be too much heat somewhere in the process 99% of the time.
Alan Singer? Alsing?The guy accused many times over of fraud and outright theft in equipment brokering deals?A new leaf has been turned?

Or can it be cured on garments at nylon temps?
Sonny what temp does the ink cure at simple question, the substrate does not determine what temperature an ink fully cures at. Who cares what Alan has figured out by testing he is not a chemist, doesnt xenon have chemists and have scientific testing to determine the inks cure temperature?

For now I would say that it cross links at around 260-270 Degrees. I will post exact numbers soon as I will be unable to do much heavy lifting for the next 3 months. This will give me time for some r&d as I recover from beam radiation and a heart procedure.
