Our EnviFlex materials are treated with a Corona treatment. This treatment uses a low temperature corona discharge plasma to impart changes in the properties of a surface of the material. This allows the material to be able to hold the ink as well as a higher resolution images when printed on. Using higher pixels per inch will give the final image a much more vibrant look. Most dye-sub fabric does not have this ability and leave the image with a "soft look" instead of a "sharp look"
