    The end product of a CMS conversion is a printed document or an image file in the gamut of a particular printer.

  • Page 12: Controlling Printed Color

    No matter what your goals are, two factors always impact color print output: printer consistency and the range of colors the printer can print, known as its gamut. These concepts are covered briefly in this chapter. Creating successful color documents and presentations also requires an understanding of color management software as it is implemented by the Color Server and on your desktop computer.

  • Page 13: Maintaining Printer Consistency

    The factors described in the following sections affect printer consistency, as well as color fidelity and overall output quality. Paper stock and toner The paper and toner used by your printer can affect printed color. For best results, use the supplies recommended by the manufacturer of the printer. Maintenance Problems such as streaking and insufficient or excessive amounts of one or more toners...

  • Page 14: Printer Gamut

    Offset press (white) Other print device You must account for the gamut of your printer when designing on a color monitor. When printed, colors that fall outside the printer gamut are “mapped” to printable colors. This process, referred to as converted or adjusted to meet the gamut requirements of a printer.

  • Page 15: Color Conversion

    The Color Server (or the host-based CMS) uses a device-independent color space to translate between the source color space and the color space of the output device.

    1-3 Simple workflows Using ColorWise color management over desktop color management relieves your computer from having to perform additional processing. Delaying color conversions until the color data reaches the Color Server frees your computer so you can continue working, and color conversions on the Color Server are, in most cases, much faster than similar conversions on a host computer.

  • Page 20: Select Your Colors Wisely

    1-4 Simple and Advanced Workflows Select your colors wisely For the colors you see on your monitor to match those on your printed output, they must go through color management, including precise calibration of your monitor and Color Server. If you are not equipped or inclined to maintain accurate monitor color management, you can opt for an easier approach.
  • Page 21 Workflow 2 using ColorWise color management—standard workflow The Color Server is highly optimized for the specific printer it supports, and ColorWise addresses many issues unique to your printer, including screens, individual toner response, interactions among toners, natural smoothness of blends, and the capability to render spot and custom colors.

    A-13 Desktop Color Primer Once you have mastered the concept of the color wheel, you have a good framework for experimenting with color combinations. Many books targeted at graphic designers show groups of preselected color combinations. Some are organized by themes or moods, and some are based on a custom color system, such as PANTONE.

  • Page 106: Raster Images And Vector Graphics

    Raster images and vector graphics Two broad categories of artwork can be printed from a personal computer to a color printer: raster images and raster image, also referred to as a bitmap, is composed of a grid of pixels, each assigned a particular color value (as shown in example a in the following figure).
  • Page 107 A-15 Desktop Color Primer The amount of data found in a raster image depends on its resolution depth. The resolution of a raster describes the compactness of the pixels and is specified in pixels per inch (ppi). The bit depth is the number of bits of information assigned to each pixel.

    A-16 Desktop Color Primer Optimizing files for processing and printing The following sections provide tips on how to create image files that produce the highest possible print quality while minimizing the processing time and disk space they require. Resolution of raster images While a 72-ppi raster image appears sharp on a monitor, the same image would likely appear pixelated when printed to the Color Server.
  • Page 109 A-17 Desktop Color Primer In this table, the shaded areas indicate that 200 ppi is typically the best trade-off between image quality and file size. However, higher resolutions (for example, 250 to 300 ppi) may be necessary for offset printing, when quality is of the utmost importance, or for images containing sharp diagonal lines.

  • Page 110: Scaling

    If the image resolution is correct for the printer, there is no quality advantage to be gained by scaling an image to a percentage of its actual size. If you scale a large image to a percentage of its actual size, you incur unnecessary file transfer time, because the image data for the entire large...

    Glossary additive color model A system in which colors are produced by combining red, green, and blue light (the additive primaries). An RGB video monitor is based on an additive color model. additive primaries Red, green, and blue light used in additive color systems.
