Even the greatest pressman can battle with registration on the press. What happens when misregistration occurs and you have type on your label? Your text becomes “fuzzy” and hard to read. How do you avoid this? Add a keyline. A keyline, in graphic design, is a boundary line that separates color and monochromatic areas or differently colored areas of printing on a given page or other printed piece. The line itself, usually consisting of a black (or other dark colored) border, provides an area in which lighter colors can be printed with slight variation in registration. It keeps type looking “clean” as we say and is usually not even noticeable.
