So I finally did a discharge underbase. They were black gildan 2000’s so I knew they would discharge well. I did 80 base and 20 white with 6 percent activator. I did two passes of the discharge and then printed 3 colors on top with no flash. I was a little worried about printing these. They came out great. I haven’t washed them yet to test but I am a little scared about the outcome. I printed the plastisol on top really thin so I am not sure if they will wash well. The colors were also based back with softhand base.

Looks awesome. What mesh counts did you use?
-
Looks great! Except one thing, It's got a little weave pattern in your garment. They will deduct points for that for sure. :) Kidding of course.

They were all 156. Printed the top color hard to make sure the color covered the discharge in the weave.

Has anyone tried a 230 using that discharge base and hitting it twice with good results? I need to get this done via high mesh.

I have and it worked GREAT!

I do it all the time. 230 base and the rest 230's as well. Works great.

Looks great! I really gotta try that some day.

Will do it today, using the artwork you have separated for us.

Glad to here it. I have had good success with 230 and one hit ( with solid art). A double hit would be even better I assume. I neglected to point out that I am specifically referring to Halftone use when I asked about 230's and discharge underbase. Anyone satisfied with that 2nd hit ( with halftones in it on a 230 mesh or even higher? Dot gain would be an issue.

Sweet!.
What brand discharge and top inks?
And what emulsion?

I am with this guy, please tell. I really need to throw some money at learning this stuff.

This job was for 50 black gildans. It wasn't set up for waterbase discharge. At the last minute I decided to do the DC underbase. I use aquasol HV emulsion normally so I just used some CCI hardener on the screen. Aquasol HV could handle 50 shirts with out hardener but better safe then sorry. The colors was just my normal plastisol inks. They are union ultrasoft or maxopake based down. The underbase was cci base and white with 6 percent activator.

You sure you used Union Ultrasoft on Discharge????????
I've been told by Joe Catazone (Union Inks) you cannot and one of my efforts using Ultrasoft was atrocious.
Maxopake, yes. Just askin.

That's interesting. The teal and blue is ultrasoft and the yellow was a maxopake. I did the wash test about an hour ago and they look great. I did base the inks back with softhand. Not sure why union would say they don't work. Maybe its just some colors. I have heard some union reds will change to orange when used with plasticharge. Maybe a union guy can chime in on why it shouldn't of worked.

Now that it's being brought up (and me being a union ink guy/newbie), what are the recommended inks to use on top of a discharge base? Want to make sure I start off on the right foot when I start playing with discharge (soon hopefully).
-
We use both Wilflex epic and Rutland C3 on top of discharge base with no issues.

This may be the case. The sample run I did some time back was with Ultrasoft Red and yes, it did turn orange and looked terrible. Joe Catazone is the person I talked to and I think his area is New York and he did tell me later that Flag Red would work but not Ultrasoft. I took that to mean none of the Ultrasofts. Like you say, maybe a Union guy will chime in for clarification.
-
Yeah, I'd like to know what ultrasofts will and won't work... I have 90% ultrasoft inks right now. Maybe I need to rethink that if this is the case.
-
I believe the reference to Ultrasofts not working is in regards to certain reds only.
The discharge chemicals eat one of the red pigments and turn it an orangey color.
This pigment may be found in other colors but will be most noticeable in bright
reds. The Maxopaque series either have a glutton of pigment or a different grade
of it. (I've heard they use an automotive grade)
-
what kind of dryer did you use? gas or electric size etc.

I have a workhorse 5217. Its electric.

the deal with makopakes is the pigment load of course the color is going to look brighter and more opaque . but in exchange you lose some hand. we have printed over discharge base plenty of times with RFU plastisols and got great results. be sure your running your electric dryer just slow enough to get the full discharge. believe me over baking it can give you inconsistant results also. 5% activator max in the base also will help

Has anyone used plasticharge as an underbase? Is it even worth it?
