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.
