When creating a Spot UV job, you must include a Spot UV mask file along with the regular print file. Please note, the mask file must be vector art created in vector-based programs such as Illustrator. The Spot UV mask file is used to show where the UV coating needs to be applied. Please only use solid 100% K (C 0%, M 0%, Y 0%, K 100%) to indicate where you would like the UV. Do not use shadows, glows, or grayscale images. White will indicate no UV.
