hi, I am getting a problematic after flash tack. 5 color job so I don't have a cooling station available.
m&r diamondback, reno hw flash
ink is cotton white, flashing it anywhere between 6 or 9 secondes give me the same issue the mesh tack on the head 3 and 4. It makes a really loud sound.
look like the emulsion stick to the print, it's a big white underbase. emulsion is chromablue.
thanks for helping me

Your white ink of choice will make a huge difference in after flash tack. I'm sure there are many great inks that will work but just as many or more that will not work well. Also a slow flash stroke. D a fan blowing between screen and pallet on head 3 will help. We use Rutland Street Fighter in these situations with great results.

We have the same setup with the Diamondback. We use Union White 1030. We do set up a fan right on head 3. also on head 3 and 4 we make the print stroke as long as we can, that can help with the screen peeling off instead of popping. And we check the pressure and make it as low as we can but still get a good print.

Also, make the flood stroke very slow, this will keep the table down and the fan cooling the just flashed shirt longer. This only has to be done very slow on one head in use.

or if its a short run have a person stand there spraying silicone as the press cycles. It's not a solution but it will get you thru on the occational run.

6-9 second flash may be a little long. I believe that over flashing may cause more after flash tack. You can run an index timer to slow the press down before it cycles, that may help you.

Also, on heads 3 or 4 increase the print stroke as to give more time to the screen to peel off on its own. Apply the right amount of pressure between 50 and 60 psi. just my 2 cents.
