Comet White Water Based Screen Printing Ink Overview

Comet White by Green Galaxy is the first phthalate and PVC free water based ink that performs like plastisol, but feels like water based ink. Light, creamy and easy to use Comet White stays wet in the screen during printing longer than any other water based white we have tested. With the ability to print through mesh sizes ranging from 110-305, Comet White not only prints great it feels amazing on the shirt. With an extremely soft hand, bright and crisp look and flexible nature, Comet White is the best thing to hit the screen printing since White Plastisol.

General Information:
Ready-to-use print water based ink for white printing on light or dark cotton and other non dye migrating fabrics. Can be printed on dark polyester or dye migrating fabrics with use of compatible low cure catalyst.

Mesh Guidelines:
Can be used with any mesh between 110-305
Stencil/Emulsion Guidelines:
We recommend using either a water resistant emulsion like Ryonet WBP or using an emulsion hardener like Ryonet Harden-X.
Mixing info:
This product can be mixed with transparent and covering ink from the AB series.
Printing Instructions:
Load screen with plenty of Comet White ink. Flood screen prior to printing. Comet White can be printed with a push or pull squeegee stroke. After printing, flood screen allowing ink to sit on top of image to avoid drying. If screen clogs or exhibits dry ink in the print, re-flood and aggressively print again, this should clear the screen. If it does not clear the screen, spray a small amount of warm water into the stuck areas of the screen and wipe out with a rag. If you are leaving your screen for an extended period of time be sure to leave your screen flooded completely. If your ink begins to scale over, spray with water to rewet ink. White can be printed with other water based inks and with plastisol inks.
Flashing Instructions:
For flashing, forced air flash is optimal. Flash until dry to the touch.
Curing Instructions:
Printed fabric should be cured for a minimum of 90 seconds at 360°F. Ideally, printed fabric should be cured for three minutes at 300--320°F.
Testing/Precautions:
After printing, perform a stretch test to ensure elasticity. It is always recommend to perform a wash test to ensure proper cure prior to going into production. You may also run abrasion testing to watch for flaking and test adhesion. Increase cure dwell time if testing fails.
Clean Up:
Ink should be removed from screen as soon as printing is completed. General wash-up (on ink that has not dried) can be done with water, though using Enviro-Solve is much easier and recommended. For aggressive or dried screens, use Enviro-Solve to dissolve ink and blast out areas of stuck ink with water pressure.
Storage info:
Keep container(s) tightly closed. Store in cool, well ventilated location that is locked.
General Safety Precautions:
Do not breathe vapors. Wear protective gloves. Do not eat, drink or smoke when using product. Wash hands thoroughly after handling. Dispose of this product in accordance with local, regional, national and international regulations as specified.

Haha he is the Rachel Ray of screen printing... "Check out how light and fluffy this ink is!" "Like butter!"

Serena you have to be able to cure it, so you can use a heat gun or oven to reach 320 and then let it dry for 48 hours

I haven't had good luck with white inks and curing consistently so I'm gonna give this product a try. Seems like a better product to start off with.

I have a very simple design that I'd like to print both on a linen fabric and on burn out tees. Would it be possible to use this ink with the same screen for both prints? If so which mesh count would you recommend I use? Thanks!

[stingah]

Can you use discharge agent with it? BTW...love your products.

[brandonakers]

I purchased this and when I received it, it was nowhere near as smooth and creamy as depicted in this video. In fact, it was super thick and clumpy. I either got a bad batch or am missing how to someway dilute the ink.

I know you can use this as an underbase as well for other water base colors on top of it, but can you use it as an underbase for plastisols?

[HakolBeseder]

Hello there. Can i use Comet White as underbase to print a CMYK design ?

[lifescircle]

Is it possible to use this ink in one pass? I don't have a flash dryer and plan on making the t-shirts quick. For example, if I used a lower mesh screen, would it come out opaque and bright in one to two passes without flash drying?

[ThisIsStyles]

I ordered this ink not too long ago & I was wondering if I left my t-shirts uncured for about a week or so, am I still be able to flash dry & cure the ink ?

[BanilyaGorilya]

I bought Comet White 9 years ago on the impulse that I’d be doing more WBD printing mixing it with other Ryobet dye additives but I never got there in my business.

[spaceratk]

I am just starting out and without a flash dryer and conveyor belt dryer. Curing plastisol with heat gun then heat press is fine but what about water based inks? can I tack dry it with heat gun followed by heatpress? or should I just stick to plastisol for now?

[ashleymoore]

I tried to print a shirt with the comet white and I didn't want to put a lot on the screen, but it seemed like the ink was flooding through the other side causing it to be blotchy... am I not using my squeege right or am I using too much ink?

[TBayJay]

I just recently have been trying Comet White water based and really like the end result so far but I find that right out of the container, it's very thick compared to my previous white which I find makes it difficult to do a production run without constantly spraying with water. Do you generally print with this ink right out of the container or are you mixing in a bit of water before production?

[so_bland]

Is the shirt for sale? The art is so cool! Maybe just the .pdf to print my own?

[brucec]

ive been wanting to try this. on long runs, how long can you print until it starts drying in the screen... especially once the pallets get hot?

[owenj]

Is there anything I can do to make my comet white more 'butter' like. It's really think I think it may be because my studio is cold.

[sherritayloe]

would love some info with the foil ....and types of machines

[munawarsoomro]

Hi. I know it's old video and I newbie trying to stay with water based and Galaxy series. You mentioned cotton or low synthetic fabrics. How would you do tri-blend or performance shirts white on black shirts? TIA for your help.

[Jim-oujs]

Hi guys,

Great work as usual.

On my side, I have a different kind of problem with white ink.

I'm in DIY mode, and after printing the ink on the shirt, when I take away the canvas from the shirt, the white ink is so sticky that it pulls up the shirt, no matter how fast I print my stencil.

As a result, there are some white ink on the shirt, some white ink on the canvas. The rendering is not a smooth white, but a grainy white.

Do you know what I could do to improve the print?

Many thanks guys,
