Sublimating on a fabric blend of 60% cotton and 40% polyester is possible, but it’s important to note that sublimation works best on fabrics with a high percentage of polyester content. The reason for this is that the dye sublimation process requires heat to convert ink into a gas that bonds with the polyester fibers.

In garments with less than 100% polyester, such as the 60 cotton 40 polyester blend, only the polyester fibers will absorb and bond with the sublimation ink. This means that when you sublimate on this type of fabric, you may experience some variations in color intensity and overall print quality compared to using 100% polyester garments.

To achieve better results when sublimating on a fabric blend like 60 cotton 40 polyester, it’s recommended to choose designs or patterns where slight variations in color and print are acceptable.

Additionally, using lighter colors or white as your base can help minimize any potential color discrepancies.
