Making a sublimation coating for stainless steel involves mixing a polymeric coating with a sublimation dye. To get the best possible results, use the layer of coating and dye as thinly as possible.
Sublimation is an excellent choice for printing high-quality graphics on metal surfaces, particularly stainless steel. This process entails transferring the dye particles from the printed paper to the metal’s surface through heat and pressure. However, it’s critical to add an extra layer of coating to stainless steel before painting to ensure that the sublimation ink adheres well.
Not only does coating ensure higher ink absorption rates, but it also keeps the ink from smudging or rubbing off over time. Therefore, it’s essential to know how to make sublimation coating for stainless steel before attempting the process. This article will cover all of the necessary steps for preparing a high-quality sublimation coating for your next project.
