using discharge as Waterbase
« on: September 04, 2018, 10:07:22 AM »
I've always been weary of being able to use old discharge ink as waterbased ink. But Im revisiting this.

Is it the type of thing, where we can use discharge as waterbased ink, at the end, or after the end of the shelf life of the DC?

Possible but the smell of finished print will most likely be horiffic if you don't post launder. Sending you a PM

Years ago I tested unactivated DC as WB- heard that many shops were running their DC base as their WB base to keep inventory simple.  Prints and cures fine but wash tests poorly compared to a WB base intended for the purpose.  You won't see the difference until you hit a certain number of wash/dry cycles.

Expired, previously activated, DC will probably "work" but I don't think it's worth the smell in the shop, let alone what the end user will be sniffing, like Tony mentioned.   Toss in what I imagine would be a lot of color variance and I can't see how it would be worth it.

Are you trying to eliminate some of the DC waste?  Ours seems excessive here, can relate to the urge if that's what you are thinking.

Exactly that.

Also lately we've been doing a lot of orders that will have black garments and white garments, and we'll need to switch from DC to WB mid way through the run. 1 colors not a big deal. 5 or 6 colors, giant time suck.

For that scenario we might print the activated DC onto the whites, provided the color works. 

As far as reducing the waste I see a lot of it in the min recipe size.  i.e. nobody likes mixing 200g of ink with PCs, it's tedious and prone to error.  Make sure the scale goes to 0.0X so you can at least encourage this.

That is the same here with activated ink on whites. usually no problems

What is excessive? Several, ten or so gallons a month or more? If properly disposed of as in cured form I would rather do that than have these massive insane ink rooms with Pantones that one reaches for every 3 to 5 years. Even then the plastisol can go bad and it does. Just curious to what others consider excessive?

Hey, previous post I did not mean to come across as rude at all. Just actually really curious to how much other shops are going through. Thanks!

YEAH WAY TO BE A JERK.  8)

We go through a 55 gallon drum about every 4-5 months. But that's wasted DC and WB/HSA with Low cure.

Gotcha'. That makes sense you have more autos than us but that makes sense in comparison with amount divided by auto. But putting in the low cure you can't use again anyway as it turns to a rock. By mixing the two does it "cure" or solidify the discharge waste in those amounts?

We have an industrial cleaner pick up the drums, and the allow us to mix up the waste together. Even though the low cure turns it into a rock, we rather be safe than sorry and compliant with disposal.
