If you are using the flash just to jell the ink, then you want the time-temp combination to just reach the jell stage. 1000 degrees at 1 inch should jell the ink 4-6 seconds.
If you also cure with the flash, at the same settings you should cure in 20-25 seconds. The temp gun only measures the surface of the ink. Do a stretch test to be sure the entire ink layer is reaching the desired temp, 320 for most inks.
Many will say the stretch test is not adequate, but in 15 years I have never had a shirt to pass the stretch test without also passing in 2 washings.
God Bless.
