About color printing
Image quality
When creating a document with color images, you first need to
understand the capabilities, strengths, and weaknesses of the
software you are using. This applies to both the PC and Mac
platforms of software such as QuarkXPress
®
, Adobe
FrameMaker
®
, Adobe Illustrator
®
, Macromedia FreeHand
®
, and
Adobe Photoshop
®
, to mention just a few of the applications
available today. Having a thorough knowledge of these programs
will assist you in creating your files correctly.
The following sections describe the different variables that affect
the output image quality. These variables include: the quality of
the original, resolution, color management, and a variety of other
factors.
Quality starts with the original
Whether your original image is a scanned transparency, a
photograph, or a digital file, the image characteristics you start
with will have a major impact on the end results. As an image goes
through the production process, it is displayed in many different
ways: as digital information in the scanned image file; as pixels of
red, green, and blue (RGB) light on the computer screen; and as
dots of cyan, magenta, yellow, and black (CMYK) dry ink/toner on
paper. During each step of the process, the colors of the original
are transformed to meet the needs of these different technologies
and the output media.
