Discharge underbase, do you flash it?

[brandon]

Yes, the super covers are nice. Testing a lot more. Expensive though. But they give nice results almost like Rutland HSA inks.

We tried their First Down poly blocker and were severely disappointed. Nothing like was advertised from the sales person at the trade show.

[brandon]

Ah, haven't tried that one yet. Will take note.

Sorry to hijack the thread!

Heating the platens first and then drop down to like a second depending on image size. Goal is just to help evaporate the moisture not see the discharge print

[brandon]

Of course depending on the ventilation we are all poisoning ourselves  just like sitting in a new car

Flash sometimes, others not.

One trick if trying not to flash is to print directly after the ub screen. Giving a thin layer of dc base time to air dry/ tack up before getting printed on can lead to problems. IE dont set it up like a plastisol base.

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

We used the first down white from Permaset back in 2008 , they shipped us a whole sample set back then from Australia. That is indeed a great white, same for the supercover white. As a matter of fact they work better then Matsui products if you ask me. Never tried using it as an underbase for plastisol though.

Everyone seems to be improving their inks which is great. However, sometimes the higher prices can't be met especially if you are a small shop like us and your clients already love your product.

To continue with the thread jack, you guys that WERE having good results with the Permaset, what mesh were you using? You have me double guessing what we did!

225s and 150s at around 24 / 25. Of course we stir the crap out of the samples and add water. Not just straight out of the bucket. However, I have only done the super covers so far. Not enough time for the other stuff till after the Thanksgiving rush.

If you have a smaller conveyor dryer could you flash the DC UB longer to cure it, then print the plastisol on top? Or does that cause adhesion problems like over flashing plastisol underbase ?

[tonypep]

That will depend on the base to white ratio in the DC/UB. We make a few different ones

[lrsbranding]

Is that ratio affected by temp, humidity, and air flow so each time is a s.w.a.g. or is there a proven standard ratio that could be used everytime.

[lrsbranding]

Tonypep, You say you make a few different ones, which manufacturer are you with?

[tonypep]

None I am the Ops Manager for a print shop.

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

Hey Rockers,

When using a discharge underbase ? Do you 50% white plasti / 50% dc base and 4% activator ?   Thinking of doing a run like this for a 6 color plasti job.
