Discharge Black?

[dirkdiggler]

Does anyone do it?  Is it necessary?  I printed Sericol black on red and its not as good as I would like.  Sericol says I need to activate it.  Just wondering if anyone else activates there black or is there another brand that works great without activating?

[ZooCity]

Been wondering this myself.  I noticed one of our dc prints out there where there was some black going on asphalt.  Damned if it didn't look a little fibrilated!  Penetation was good, everything else seemed fine, used Matsui Black which I think is great ink. 

If the wb is still going to fibrillate, may as well use the plastisol.  So I'd say try it side by side-

Texcharge Black (unactivated)
Texcharge Black (activated)
Regular WB Black

That Matsui spot black is so damn dark it'll bend light . . .

[patfinn]

ive done it.. it turns like a greyish color. not black. i agree with the spot black that stuff is BLACK! but I have never had issues with sericol.

what are you going to do discharge black on? White?

on Red, if you dont discharge it, it doesnt cover very well.

Tom are you talking about a RFU Matsui black? I've not seen a product like that. I just mix my black with PC Pigments, with just decent results....nothing like your description

There's Pantone Black and spot black. The Pantone black is so-so. The spot black is really dense . . . like coal . . . flat . . . hard to wash the stain out of the screen black. Mine was anyway. Not RFU, but mixed in the base from the pigments.

Yup, Matsui Jet Black. Comes in 5 and 1 gallons from Matsui directly. Been our black water base of choice for years. However, we start our trial period this week with nothing but the entire new line of CCI discharge products. See how it goes for the next couple of weeks

Me too. I've got CCI Pigments and bases and I have what is purported to be an especially nice bright red formula with CCI, which I've ALWAYS had difficulty with, prior to Sericol's Yellow Shade Red....which I tweak.

I LOVE the CCI bases and D-White especially. Haven't even opened the box of Pigments yet, even though I've had them for weeks. (Weird, I know...)

Thanks for the tip, Tom. (oops...Brandon I meant. Sorry...)  I'll be interested to read your impressions of the CCI stuff.  I've been waiting for a slow spell to play with it, myself.

let us know how that red works out, i got there pigment set and have not been able to get a decent red.

Here is what I was given for the bright CCI discharge red, but I can't say how (or if) it works yet.

  6% Rubine,
~3% Orange (or ~3% Warm Red depending on what you want)
  6% 032
  3% Activator

15% seems like a lot of pigment loading to me. I got this from a CCI rep who reportedly is moving a LOT of product.

Personally, I have good luck with the Sericol Yellow Shade Red which I tweak as follows, in multiples for whatever size batch you are looking for.

100   grams YS Red
100   grams of CCI D-Base
10     grams Matsui Neo Red Pigment
6.5    grams of activator

I am considering ordering a gallon of the Matsui Jet Black waterbase, unless someone likes the Sericol better. I can't imagine why I would ever need to discharge it, if it is as black as Tom said. I don't remember if I've ever printed black waterbased on red shirts, but even what I do... with just PC black Matsui pigment... seems to work on all the colors I've tried.

Brandon,

I am very interested in hearing your take on the CCI products. I have been using them on about 12 jobs now and I am liking them. I have very little experience with this stuff and can't even really compare it to another brand since I never used Matsui enough. So far I am liking the easy of use. I am yet to use a mixer. All my color mixes are just mixed for maybe 30 seconds with a goop scoop.

Careful with that.  You should be using a high speed mixer imo.  Especially with wb PCs.  According to some manufacturers, wb inks need a high speed shearing/mixing to disperse properly and completely. 

Aside from that, you have the discharge activator that needs to be evenly dispersed.

It doesn't take long to do it and it's easy to clean off the paint mixer being wb.

I am sure your right. I mix my ink then add activatorr. Then mix for about 20 seconds. let it sit while I am setting up the press and then come back and mix it again. Never had an issue yet. I have a drill press that I am thinking about setting up as a mixer. I guess I just need to find the time...
