Uv inks and coatings are desirable because they essentially do not contain solvent that must evaporate during the curing phase. The cure takes place under a strong UV (ultra violet) light source in a dryer (or reactor). Since UV contains little or no solvent, there is a lot of interest in using it because of the lack of VOCs (volatile organic compounds). VOCs can be potentially hazardous to breathe and dispose, thus the reduction is appealing to the environment. Setting up a Spot UV job: When creating a Spot UV job, you must include a Spot UV template file along with the CMYK color printing file. The Spot UV template file is used to show where the UV will be placed. Use black to indicate where you would like the UV and white where you do not want UV. Difference between 4-color process vs. PMS spot colors: Process color printing uses the color model that describes each color in terms of the quantity of each secondary color (cyan, magenta, yellow), and key (black) to produce virtually any color. PMS color matching uses a Pantone color guide to pick an exact color specified. We have press capabilities that can print up to 8 colors, which gives you the opportunity to use 4 color process with additional spot colors and/or finishes to get a truly desirable finish.
