Cheap Youth Basketball Jerseys Customize Basketball Gear. Most of the time, customers send us their own designs for custom sublimation basketball uniforms or basketball jerseys in ai or pdf vector format so that our designers can use the design for the jersey directly. Additionally, when a customer sends us their logos, background graphics, and color preferences for jersey sublimation, we will arrange our designers to produce a design proof alongside the particular jersey pattern for approval. We will use a digital sublimation printer to print the jersey sublimation design onto sublimation paper following their approval of the design. A heat transfer machine will then use heat pressure to print the design onto the fabric. Selecting the appropriate fabric for sublimation on custom jerseys is essential prior to heat transfer. Because different jerseys are made from different polyester fabrics. For sublimation shirts and sublimation jerseys, we typically use white fabric 100% polyester. And for sublimation hoodies, we use polyester fleece blend fabric. We typically use 100% polyester fabric with a 160gsm weight for sublimation basketball jerseys. This fabric is breathable and can manage moisture to keep you cool and comfortable.
