I have seen some guys talking about how great a ticana is, I have a Ticana and a red chili. I purchased the ticana to be my main flash, and the red chili to be a movable secondary flash. I have about 14K prints on my sportsman now, and I find that even after the ticana is heated up, the cured ink is semi striped if you do a white, and flash, and a secondary white, or other top color.
When I use the red chili, this problem is eliminated. I have tried every combination of dwell time and power settings, and my red chili is far superior. Both are set to the same height from the pallet, and if I set the dwell times to match, or use the quartz dwell timer on press( I have press cables for both) the red chili will not leave striping, and the ticana does. The stripes seem to be between the bulbs.
To the touch, the ticana leaves the white with no tacky in it, The problem lies once the piece has gone all the way through the dryer. If I reduce the power, or time, the ink is not cured enough to put a second color over.
I am using wilflex quick white as the underbase.

too hot! I have the same flash with no problems.

make sure your flash is as high as it can go and preheat your pallets prior to starting the run. Red Chili was short wave but just switching to med wave and Tacana,Cayenne is medium wave infrared. I think you need to pre-heat your pallets mostly.

try preheating your pallets like Rich said prior to running your jobs. make sure you are not over flashing once you get rolling :)
if that doesn't solve it for you right away give us a call at M&R and ask for the screen print dept. 1.630.858.6101

I think you will find it's your pallets not hot enough as well. We ran into this on the Cayenne D a few times early on. But never see it now.

This last job that striped was a 500 piece, white on white, shirt was 100% cotton Kelly green. White on 135/64 in 1, Ticana in 3, white on 160/64 in 10. 2.5 second flash time, 4 second index. I thought they looked great coming off the press, and the person catching did not notice the striping. I was helping box them when I noticed. It was almost every one. The pallets were pretty hot to the touch.
I do know my Ticana and red chili had two separate part numbers for the bulbs, but not sure if one is short wave and the other med, or what. Which is better? They are both set on 100% power, but the red chili seems to work better.
Could the flash being too hot cause it? Why would you only see it after the ink is cured through the dryer?

medium wave is better. Check the height of your flash. You should also speak to your ink supplier. Where are you located?

I am located in northern Kentucky.
The ink used is wilflex quick white.

2.5 seconds on a Tacana is WAY to long. Especially for 500 shirts. I usually start on 2 after the pallets are hot and lower to 1.5 or 1 at about 50 shirts in. Been using Tacana for 14 years that way with no problems.

it's the temperate of the run that we need to concern ourselves with more than flash time. If it's not hot enough, it won't gel.

I'm thinking height; one of the early flash units we had years ago had a bulb/ reflector combination that did the same thing; we had to rise it to where it produced
a consistent layer of heat over the ink, but then, we got a better flash to replace it that had a better pattern, so we could run it lower and faster.

that ink flashes pretty quick normally. It still sounds like its too hot.

This just happened to us last week. We were running some white t's with 4 colors. There was a large ink area of gray that was being flashed just so it would not pick up and my guys started to get some banding. I started looking at it and found that they were using a gray that we had made from some Performance White and Performance Black. They were flashing at 2.5 @ 100% power. It was too hot and causing some discoloration in the gray ink only. Turned it down and it went away.
