PRINTING TERMS GLOSSARY
G
- galley
- Traditionally, proofs of type printed in final column width for the purposes of proofreading and layout checking.
- gamma
- A measure of contrast that affects the mid-range grays (midtones) of an image. Gamma is often expressed as a curved or straight slope.
- gamut
- The range of colors that a device can reproduce. The naked eye, the camera, the computer monitor, and the four-color printing press all have different color gamuts. The eyes range has the widest gamut and the printing press has the narrowest.
- gamut mapping
- The process of color matching in which differences in color gamuts between the source device and the target device are taken into consideration.
- gamut simulation
- The process by which a device with a wider gamut can simulation the behavior of a device with a narrower gamut.
- gatefold
- A four-page insert or cover with foldouts on either side, making the equivalent of 8 pages.
- GCR
- Gray component replacement. A color separation technique that uses black instead of combinations of cyan, magenta, and yellow in reproducing the gray components of colors. This provides a more economical use of inks and improved color trapping.
- GIF
- Graphic Interchange Format. A platform-independent image file developed by CompuServe that is commonly used to display and distribute images on the Internet. It can contain up to 256 colors.
- gopher
- An information retrieval system widely used on the Internet.
- Gothic-style typefaces
- San serif typefaces.
- graduated colors
- A graded series of colors that changes progressively from one color to another or from light to dark or dark to light within the same color.
- grain
- In paper, the direction in which fibers line up.
- gray component replacement
- See GCR.
- grayscale
- The range of intensity increments between white and black.
- gripper
- The part of the press or printer that holds the paper and guides it through the press. Also, the edge of the paper so held.
- groundwood
- Pulp made by mechanically grinding wood to separate the cellulose fibers. Groundwood pulp is used in less expensive papers, such as newsprint, where less strength and brightness are required and lower cost is important.
- gutter
- The space between columns of type; the place where pages meet in a book or booklet.
