No way, if we had to wait a minute on our oven we would print as slow as manuals.We print at full production speeds on a small electric 54" wide no problem. Wash test all the time for safety, we would do that even if we had a gargantuan oven as well.

instantaneously once the entire deposit reaches it's cure temp. Plastisol doesn't have to be at a certain temperature for a length of time, just has to reach that temp that it was made to cure at. Most plastisol inks these days cure at a lower temp than 330.
Alan that is not 100% true. For Example Quick White from Wilflex does require a longer dwell at the curing temp of 320. Just getting there is not enough.

Most plastisol inks these days cure at a lower temp than 330.That blanket statement is kind of like saying all screenprinters are aging, ponytailed, balding, wanna be hippies, who bootleg tye-dyed Deadhead shirts in the parking lot before they get stoned at a GD concert. While it may be true in many instances, there are exceptions.The plastisol ink guys should chime in here but some of the 'newer' plasticizers require being "held at cure temp" to allow complete conversion to washfast solids.Ink guys where are you.....
