galley
|
1. Unaltered phototypesetter output, usually single columns
of type on photographic paper, serving as preliminary proofs.
2. Final image or typeset copy output directly to film or
photographic paper 3. Initially, a long, shallow tray for
storing and proofing handset type.

gang
|
A grouping of forms arranged to print together with a single
impression. Also known as gang printing, gang run, or gang
up.
|
|
gatefold
|
A four page insert to a book that is larger than the existing
page dimensions, having a fold at the outer edge that serves
as a hinge, allowing two sheets to fold out from the center
to the edge. Also known as a foldout.

|
gathering
|
Assembling all the signatures in order. See also: assembling;
collate; inserting.
|
|
gigabyte
|
One thousand megabytes or one billion bytes of computer data.

|
gilding
|
The application of gold or metallic leaf to a book’s trim
edges.
|
|
glassine
|
An opaque smooth paper used primarily for candy wrappers
and dust jackets. Formerly used in book production for the
separation of text pages from graphic pages.
|
|
glazed
|
Paper with a surface sheen or polish applied during or after
manufacture by calendering, drying, plating, or drying.
|
|
gloss
|
The "shininess" of a material as measured by the amount of
light reflected from its surface. Alternative term: specular
gloss.
|
|
ghosting
|
Also known as gloss ghosting. A condition occurring during
sheetfed printing when inks containing drying oils are used
in production. Vapors from drying ink on one side of a press
sheet interact chemically with the dry ink densities printed
on a sheet in contact or on the reverse side of the same sheet
creating unintended faint images.

|
grain direction
|
1. The alignment of pulp fibers in the direction of web travel
during the production of paper. 2. “Grain-long” is the grain
direction paralleling the longer dimension of the sheet. “Grain-short”
paper has fibers paralleling the short dimension of the sheet.
3. In the production of bound materials, the grain direction
of all papers used must run parallel to the backbone to prevent
cracking and insure a durable spline.

gravure
|
A printing method that uses ink-filled depressions in a cylinder
to deposit ink on a substrate, forming an image. The small
depressions, known as "cells", are etched into the cylinder
to form the image. Ink is flooded onto the cylinder and then
removed by a blade scraping the cylinder surface. Only the
ink in the etched depressions remains and is transferred to
the substrate on contact. See also: rotogravure.

|
gray scale
|
1. Graduated neutral tones used in printing to reflect color
differentiation. 2. A film strip used in combination with
original photography to check focus, provide print contrast,
time development, measure density ranges, balance color, etc.
Also, gray wedge; neutral wedge, or step tablet or wedge.

gutter margin
|
The space between the text matter and fold edge next to it.
Alternative terms: back margin, binding margin.
