points, control handles, and tangent lines.
The PostScript path passes through
anchor points. Its approach direction is
along the tangent lines that are controlled
by the control handles. Many personal
computer programs use this drawing
method. Type 1 PostScript fonts are
defined using Bezier curves.
binding
The cover and materials that hold a book
together. See
edition binding , perfect
binding , spiral binding , wire-o binding .
The process of applying the binding to a
book.
In InfoPrint, assigning a job to an actual

bitmapped
Pertaining to an image formed by a
rectangular grid of pixels. Each pixel is
assigned a value to denote its color.
One-bit images are black and white; 8–bit
images have 256 colors (or grays); 24–bit
images have full color. CMYK images
have 32–bits per pixel to encode 256
levels in each of four channels. Bitmapped
images are also called raster images.
bleed An extra amount of printed image that
extends beyond the trim edge of the
sheet. Bleed ensures that no white gap
appears at the edge of the sheet.
boot To prepare a computer for operating by

burn In platemaking, an exposure. Burn is
named because of the extremely bright
ultraviolet lamps used to transfer images
from film to plate.
In photography, to lengthen the final
exposure time to increase the final density
of print.
C
cathode ray tube (CRT)
A vacuum tube in which a beam of
electrons can be moved to draw lines or
form characters or symbols on its
luminescent (phosphor-coated) screen.
CRTs are the heart of all modern
