Green Galaxy's Clear Core Base is a transparent water based ink that allows the printer to add water based pigment to create color and Pantone match. Clear Core is not only eco-friendly but extremely friendly to the printer because it stays wet in the screen allowing you to screen print for hours at a time as long as there is plenty of ink to flood the screen. With prints that are vibrant with color but leave an incredible soft hand Clear Core is an awesome solution for printing on high-end fashion garments, as well as athletics and standard t-shirts. Clear Core Base is the core of Green Galaxy's Pantone mixing system but is also compatible with our current R2O CMS mixing system as well as other water based pigment systems on the market.
Printing on dark garments? If print using Comet White and over print using Clear Core + 20% Opaque Core + pigment color in order to add body and opacity to your overprint.
Printing on polyester dye migrating fabrics? Add Warp Drive to Comet White and Clear Core to lower the curing point and avoid dye migration.
Clear base for color mixing to print water based ink on light fabric. Can be printed on dark cotton fabric by under basing with Comet White. Can be printed dark polyester or dye migrating fabrics with the use of compatible low cure catalyst.
Can be used with any mesh between 156-305
We recommend using a water-resistant emulsion like Baselayr Complete. It is recommended to degrease your screens with Baselayr Emulsion Prep. For extended screen life and long print runs it is recommended to post expose the screens and/or use an emulsion hardener like Baselayr Emulsion Hardener.
This product can be mixed with Opaque Core for opacity, Comet White, Green Galaxy Pigments, as well as other water based pigments such as R2O CMS (link). If using R2O CMS Pigments add 10% pigment by weight to Clear Core Base.
Load screen with plenty of ink. Flood screen prior to printing. Clear Core 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.
For flashing, forced air flash is optimal. Flash until dry to the touch.
Printed fabric should be cured for a minimum of 90 seconds at 360¡F surface temp. Ideally, printed fabric should be cured for three minutes at 320¡F. Always test your cure by performing abrasion and wash tests prior to sale of garment.
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.
Ink should be removed from the 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.
Keep container(s) tightly closed. Store in cool, well ventilated location that is locked.

works like a charm
I'm a big fan of the Fusion system. My opinion, whatever the recipe calls for, I always just go 50/50 with the opaque and clear bases.
Hey Paul, Glad you like the mixing system. Pro tip: add white last at 50% mix and then add more white as needed.
Love this stuff
I always love using Green Galaxy. It flows excellently, makes any water based ink more transparent and is great for monotype printmaking. Can't recommend it enough!

Works beautifully with natural plant lake pigments!
I'm not an experienced screen printer by any stretch. However, I am a plant person and have been making a lot of lake pigments from the dye plants I grow. I really wanted to try screen printing with them after learning about it in a workshop. I found this ink when searching for clear water-based ink and it works BEAUTIFULLY with my plant lake pigments! I don't even have "real" screens, but instead used it with "mesh stencils." I have no idea what gauge the mesh is, but just to say, this stuff seems pretty versatile to me since it worked great with the "easy" mesh stencil application and I didn't need anything special! One thing that was a little weird, though not a knock on the product- just some mysterious chemistry- is that I added some ferrous sulfate (iron) crystals to the ink after I successfully mixed in the pigment. Iron shifts natural dyes to make them darker and "saddens" the color (think yellow shifting to khaki/olive). It DID do that, but what was weird is that it immediately LIQUIFIED the ink! Like- pure liquid viscosity! I had to run and pick up my kid, so left it out on the glass palette where I was mixing and it had thickened-up again when I got home. But another mystery of chemistry is that it was now a shade somewhere between the original shade and the dark (but liquid) shade. Ha! I can totally work with this now that I know what to expect, but super interesting.
Deena, We appreciate the time you took to leave us this awesome review. If you've got any pictures of the prints you've successfully done, we would LOVE to see them. It's always interesting to see what our customers are experimenting with and on. Thanks again& Happy Printing - Nick from Ryonet
