Our paper is a thicker weight that holds more dye (ink) to yield a deeper, more vivid image that’s great for soft as well as hard substrates. Whether you are imaging shirts, pillows, mouse pads, ceramics tiles, mugs, aluminum panels, glass cutting boards or the 100's of other sublimation products & substrates ...our premium transfers are printed to provide stellar results transfer after transfer.


-Accepted file type(s): PDF, PNG, TIFF, JPG,, EPS
-Color Format: RGB
-File Size / Resolution: 200 to 300 d.p.i
-Do not mirror / reverse your images. (We do that for you.)

VERY IMPORTANT Your transfers will only turnout as good as the files you use. If you desire to use a low quality, blurry, internet-size graphics (72dpi or less) you will receive less than ideal transfers. If you are unsure of your files quality, PLEASE ask questions and/or send us your file(s) PRIOR TO ORDERING for us to evaluate the quality.


Submitted files SHOULD BE "PRINT READY"(Do Not Mirror). Minor altering can be / may be provided for an additional graphic fee. However, contact us prior to ordering for graphic design availability. Refunds will not be honored due to ordering with the intention of receiving design creation.

Dye Sublimation DOESN'T have White ink and DOESN’T image dark / black fabrics. Any white in your graphic will be void of color (no ink). *Shirt color will show in white areas of your graphic.

Dye Sublimation works with WHITE or LIGHT COLOR polyester fabrics or hard goods SPECIALLY COATED for dye sublimation technology. 100% poly will provide the best, most vivid, full color results. Poly blend fabrics are usable however the results will be a much lighter, more vintage look.

🕱 → 100% cotton, hemp, wool, or natural fabrics WILL NOT image with Dye Sublimation.← 🕱
