What mesh counts can be used with this white discharge ink? And do you have any off-contact with the screen, or is the off-contact zero? I've read with waterbase inks to have NO off-contact to help drive the ink into the shirt vs. laying ink on top of the shirt like with plastisol.

Oh, and I'm looking at the Ryonet white discharge ink, and their regular white waterbase ink. Which one do you think would give a brighter, more opaque white, and last the longest on a black shirt?

Thanks

[CatspitProductions]

@jasonlsmith3 I think you can use a variety of mesh counts. The discharge base and the discharge white are thinner inks. I did this video with a 110 just because that’s what I had handy for the video. Ryan from Ryonet did a video on this with higher mesh counts. I always use a bit of off contact. Your stroke will always determine ink penetration more so than off contact. And the brightest white will be achieved with the discharge white. Thanks for watching and leaving a comment! ☠

Would you use the same mesh count for white discharge ink that you would use with a regular white opaque ink? Can you use any plastisol ink with the discharge base, or does it have to be an ink made for that purpose? Would you charge a customer more for printing the shirt with discharge ink?

[CatspitProductions]

@johnk6749 First, maybe not but you could. Discharge white will be thinner than regular opaque whites. Secondly, yes, you can use plastisol with the discharge just make sure the discharge is flash cured first. Lastly, yes I most likely would as it is more difficult to work with than regular water based or plastisol. It’s not hard it just takes a little more effort.

Great video! Just curious though...what is the benefit of using a discharge ink v/s a regular plastic? Seems like a lot of work if you have a large quantity of apparel.

[CatspitProductions]

@knm62774 Thanks, glad you like the video. It’s really not much more work. Just a little different and it might take some time to get used to working with this type of ink. But with a well-made stencil you could do high volume no problem. And it produces a print that feel like nothing. Just feels like the shirt. It’s called “soft hand.” That’s the effect you would be after here. Thanks for watching and leaving a comment! ☠

One thing I'm curious about. I print inside my home. Does the dishcharge ink/salt put off any toxic fumes more than regular plastisol? I have a wife and kids & don't want to expose them (or myself) to anything harsh. thanks John, again great video.

[CatspitProductions]

@misterscreenprint As long as you have good ventilation, you are fine. I have to say it is way better than it used to be. This discharge stuff used to reek very badly. But now it has a tolerable rubbery type smell. It may permeate the house some unless you vent well. But I am not doctor. Look into it if you are concerned. Thanks for watching and leaving a comment! ☠

[misterscreenprint]

"Don't eat it"...LOL hilarious :)

you could also have re-zeroed your scale after the ink was in the tray and just added the "salt" till it showed the 6% equivelent. dont know if it would be any easier but...I'm just sayin' :D

thanks for another awesome video!

[CatspitProductions]

@misterscreenprint Yea, it may have been better that way. I thought of that later too but I always like to complicate my mathematical stuff. That’s why I’m so good at it….LOL. Thanks for watching and leaving a comment! ☠

[mahousel]

Thank you so much for this one it was awesome. I will say i was also surprised at how good you could see the white in the shirt. When i did my research paper on dischare the product i used you could not see it at all untill you cured it or evaporated the water from it. Also i was surprise at how thick it was it did not seem runny at all. I had one question i may find it when i look it up but whats the self life of the brand you used hear? Again awesome vidow very cool

[CatspitProductions]

@mahousel Thank you, glad you like the video. Yes, standard discharge base will not have the white pigment therefore it will not be white until activated by the heat. This is a discharge white which has a lot of white pigment in it as you can see in the video. It is much thicker than the discharge base alone because of the white pigment. I think the shelf life is about 6 to 8 hours. Thanks for watching and leaving a comment! ☠

[O2BIon]

When printing with discharge ink, is it necessary to use a forced air conveyor or flash dryer? Thanks.

[CatspitProductions]

@O2BIon It’s not necessary but it will work better and faster with forced air. Thanks for watching and leaving a comment! ☠

[mark2bit]

That stuff STINKS!!! I'll never forget that smell.

[CatspitProductions]

@mark2bit LOL… yea, it’s not as bad as the stuff was years ago but it still has a rubbery smell to it. Not too bad though. Thanks for watching and leaving a comment! ☠
