Glossary of Print Terms

R

Register Marks

The printed marks used to align color separations for printing so that each color registers with each other. These marks are printed using all the color separations of process printing so pressmen can check and adjust the alignment of each plate.

Reverse Type

When the type on a design is not printed so the color of the paper stock shows through. This is most effective when there is high contrast between the image and the stock.

RGB

RGB is an acronym for the three colors used to create the broad array of colors displayed on an electronic monitor. The three primary additive colors are Red, Green and Blue. RGB colors are used for electronic displays but do not reproduce well in print. RGB images should be converted to CMYK before your files are sent to the printer or it will be done during the pre-press process.

A specially mixed ink which creates a specific color to be printed on press. Spot color inks are opaque, not translucent like process color inks. Printing with spot colors requires only one plate to print the color versus four when printing with process colors. Adding a spot color to a process job (usually done to ensure the color value of a logo or other standardized color) adds a fifth plate (one each for cyan, magenta, yellow, black and the spot color).
