Green Galaxy Clear Core HSA Water Based Mixing Base - Gallon

Ryonet's Green Galaxy™ 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 the Green Galaxy’™ Fusion 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.

General Information:

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.

Mesh Guidelines:

Can be used with any mesh between 156-305

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 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.

Printing Instructions:

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 re-wet 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 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.

Clean Up:

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.

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 the product. Wash hands thoroughly after handling. Dispose of this product in accordance with local, regional, national and international regulations as specified.
