Hi, I am new on this forum so I don't know if this is the appropriate place to post this topic. I have the Roland VersaUV LEF-12 and I am having trouble printing on black products. When I print on black products, the image is very fainted and not vivid when i use colors. I also tried using white ink on black products but can't seem to have the white color stand out. The only way I was able to have the white color stand out is print the area over a few times until the white becomes very visible. Can anyone provide me with some assistance? Is there some kind of setting on the printer itself or on photoshop and/or illustrator? Does anyone know the settings? Also do any direct me to any sites that can provide full instructions? Thank you in advance.
