Swatch books help you determine the closest printed color to a color you are trying to match, or create a desired color when it is not printing as expected. By specifying a color recipe, you can take a sampling of a source color and its variations to print multiple swatches and determine which is closest to the desired color.

To create Swatch Books, you select the number of desired patches and a +/- degree of change using SaturationTerm used to describe the strength, purity, or vividness of a hue. Saturation indicates how much color is present. When there is no saturation, there is no color; the more saturation, the more color there is of the given hue., LightnessPerception by which white objects are distinguished from gray objects and light- from dark-colored objects., ChromaA three dimensional graph called Color Space. We can assign an absolute value to any color using three independent variables: Lightness, Chroma, and Hue. or Hue1. A tint or color specified by an angle on the HSV Color Wheel. Going counter-clockwise around the wheel, hues shift from red to yellow to green to cyan to blue to magenta and finally back to red. 2. The attribute of a color that permits it to be identified as a specific color. Hue combined with Saturation and Value fully defines a color. as the variant between the patches.The printed swatch is then reviewed to determine the closest color to the desired target color. Each patch lists the associated color recipe and a color replacement can be made using the recipe of the color deemed closest to the target color.

To access Swatch Books:

You can access the Swatch Books dialog through RIP-QueueAn organized list of jobs that are printed on a first-in first-out (FIFO) basis. or JobAn image coupled with RIP-Queue settings. Editor by clicking the icon on the toolbar. (Figure 1)

You can also get to the Swatch Books dialog through spot color replacement in Job Editor. (Figure 2)

1. Click the ColorThe attribute of visual experience that can be described using the dimensions of Hue, Saturation, and Brightness. Correction tab, then Tools > Color Replacements
2. Click the first button to add a new color, which opens the color replacement dialog.
3. Once you have a color selected, you can click the Swatch Books button.

Swatch Books dialog:

The Swatch Books dialog is broken into five different areas (Figure 3):

Swatch Generation

There are three types of Swatches available:

1-Dimensional: Allows horizontal variation of the source color

2-Dimensional: Allows horizontal and vertical variations of the source color

3-Dimensional: Allows horizontal, vertical and individual page variations of the source color

The number of corresponding patches can be selected relative to the Swatch Type selection. The PatchSingle color sample contained in a swatch. Used as part of profile generation. Width and Height and Label Gap and Patch Gap are defined by the user.

Source Color

This displays the currently selected source color; the selected color space and current device values.

When Swatch Books are accessed from the Color Replacement dialog the source color will already have been selected. To change the selected color, click Edit.

When using Swatch Books without starting with color replacement, you will need to select and edit the source color by clicking Edit.

Color Type

Select the color type from any of the following:

CMYKSystem for describing colors based on a combination of values for Cyan, Magenta, Yellow, and Black; the ink colors used in four-color process printing. In theory, 100% of Cyan, Magenta, and Yellow create Black. In practice, the addition of Black ink is necessary to print a true Black. See also RGB.

RGBSystem for describing colors based on a combination of values for Red, Green, and Blue—the additive primaries. RGB is the basic additive color model used for color video display. Mixing various percentages of red, green, and blue light can recreate most of the spectrum; combining 100% of all three creates white light. See CMYK, Additive Color.

Spot ColorA specific color or type applied to individual graphic items.

Device Values (Printer Ink Channels)

You can also measure a source color using a supported hand-held spectrophotometer.

Auto Patches

When Auto Patches is selected, you can choose the type of variation and the +/- degree of variation to be applied to the swatch.

Select a variation type from the following:

Saturation (1-Dimensional Only)

Lightness

Chroma

Hue
