Discharge underbase, do you flash it?

[Rockers]

When printing plastisol onto a discharge underbase do you flash the base first our do you print it all wet on wet?

[mimosatexas]

I do, but I'm on a manual.  Never had good luck printing on to a wet dc base.

I do a quick flash, about 2 seconds.  I've done it with and without and things work just fine without flashing but I feel like there is some buildup and mixing of the plastisol and DC ink that can be avoided by a short flash.

Yes. 

Like Al said, just enough to dry it out a bit typically.  You aren't printing a DC UB like you would regular DC, it's not about saturating and fully penetrating the fabric, that's not needed, just need to bleach out the top of the garment so the plasti hilite colors pop.  So it's a lot less ink all around and doesn't take much to flash out enough moisture to prevent issues down press.  Still, be careful with ventilation here it can get a lot of nasty in the air at higher production speeds if you don't watch it.  Depending on the temp/humidity in the shop and the fabric, etc. I like to see the image just barely start to discharge before the quartz kicks off.

We've ran without flash and it looks fine too...until the wet DC starts clogging your 330/30 CMYK screens and you can't see that the skin tone went from tan to sunburnt for 30 shirts as the Y clogged and then from sunburnt to pallid as the M starts gumming up.  After that experience we just flash all DC UBs, makes life a lot better and you can see what's going on more clearly before pulling the garments.  I've also seen a slight opacity boost doing this v. not flashing.

Every time I see a post like zoo's I think I'm gonna start saying, "Dont have this problem with plastisol."  I'll equally sound like a broken record in no time ;-).

I recently tried not flashing a DC UB with a flou. Orange top colour and we had significant drop-out of brightness in the finished product. A quick flash fixed it

Ha! You sound like me and my production manager when we're down on wb printing.  But man, plasti over DC base v. over plasti base?...no comparison imho, so much softer, smoother, better blends.  I think it's worth it.

I would really like to hear from someone who doesn't flash the base, it's something I really, really want to get away with but it has not been production friendly enough and the finished product with a flash looks better.  If you don't flash DC bases, I want to know your secrets.

How are cure times affected using a dc ub?

[TCT]

We flash. When I stop and think of it, it is usually more out of habit than anything I think. Like other said it is like a 3 sec flash, somewhere in my head I've told myself it looks better.

Pretty sure Tony said they don't usually flash.

Our dryer is 16' of high output/high airflow so DC UB runs at 320˚, same as an all plasti print.  However, we would not run super fast as we could do with all plasti, there's a retention time needed to get the DC UB to do it's thing.

last job we did like this we had to flash longer than i wanted to, it was on gildan 18000 blacks. But without that added flash time, it really looked gross.

I'd like to get into doing dc's but 6ft of infrared is not gonna cut it.

Permaset makes a "first down white" underbase non discharge. Flash all you want nothing bad in the ink. Print water base or plastisol on top

Have you used any Permaset stuff with success? The samples they sent us blew ballz!!!
