Issue with post flash tack
« on: February 28, 2017, 05:29:29 PM »
I have a huge order in that we started today.  All baseball jerseys so I am using the IC 7113 Performance Pro White.  I have used this product for a while but most of the time it is single color P/F/P stuff.  For this particular job I am using it for an underbase and then putting 1 color on top.  Problem is I am getting a ton of post flash tac.  Feels great after first flash but when I hit it that second time and send to the flash it comes out extremely tacky and is really a PITA to work with putting the second color on.  What can I do besides change ink.  I have started using Synergy Poly white and like it but it is not shiny enough for the jersey look.  Using 110 for the poly white and 135S mesh on the colors...simple spot jobs.  What can I do??

My first general suggestion is to have a cooldown station, but I also have to ask why you are P-F-P'ing an underbase? That's a lot of ink for something that doesn't (shouldn't) need to be solid and really opaque. That has to be adding to your problem.
That rug really tied the room together, did it not?

Well the top color has a white outline. Since this Job is already about 30 different screens for all the teams I wanted to get away with not using a highlight white. Just p/F/P the underbase and adding the color on top. I am printing these manually

I also print on a manual. When I have a problem like this, I have a fan mounted after the flash, careful to not let it blow towards either the flash or the main dryer. I use a regular room fan on a tall stand but ideally, it would be a box fan mounted horizontally.

You could try to clean the screen really good, your overprint color that is...then give the screen a light spray of silicone spray. Wipe with a rag to remove any residue and see if that solves it. I commonly used this method on automatic presses when I was forced to use the print head after a flash.
Nothing is more difficult than the art of maneuvering for advantageous positions.
