How to Avoid Blotchy Results Occurred in Sublimation Process
B lotches and spots in your transfers can happen at any time and anywhere . T his is a problem generally caused by excess moisture in the environment or on the substrat e. Left : Perfect transfer result. Right : Blotches and spots in a poor paper Common sublimation materials like polyester fabric, hardboard, plastic and even metal materials like aluminum and stainless steel can be sublimated, and w hat happens when there is moisture on a substrate? When water is heated , it turns into steam vapor which starts to escape upward , however, since dye-sublimation ink also turns into a gas, the steam vapor from the areas that have even the smallest amounts of moisture clash with the sublimation gas which will prevent a full and consistent transfer . So how to resolve this blotchy results ? The quick solution is to pre-press substrates immediately before applying & heat pressing the sublimation transfer. Pre-pressing is done by...
