Choosing color-conversion settings
When you choose color profiles, colors are matched between devices as closely as possible by the color management module (CMM) of the
Microsoft Image Color Management (ICM), which is the default CMM. Color management modules are also known as “color engines.”
You can also use the Adobe CMM if it is installed on your computer.
Handling pure black and grayscale colors
You can preserve pure black color in the destination color space during color conversion. For example, if you are converting an RGB
document to a CMYK color space, pure RGB black (R=0, G=0, B=0) can be mapped to pure black CMYK colors (K=100). This option is
recommended for grayscale documents or documents that contain mostly text. Note that preserving pure black during color conversion may
create solid edges of black in effects and gradient fills that contain black.
By default, grayscale colors are converted to the CMYK black (K) channel. This process ensures that all grayscale colors print as shades of
black, and no cyan, magenta, and yellow inks are wasted during printing.
To choose color-conversion settings
1
Click Tools Color management Default settings.
2 In the Color conversion settings area, choose a color engine from the Color engine list box.
You can also Do the following
Keep pure black in the source color space as pure black in the
destination color space
Enable the Preserve pure black check box.
Map grayscale colors to CMYK black during conversion Enable the Map gray to CMYK black check box.
Soft proofing
Soft proofing provides an on-screen preview of a document as it will appear when it is reproduced by a specific printer or displayed on a
specific monitor. Unlike the “hard-proofing” technique that is used in a traditional printing workflow, soft proofing lets you look at the final
result without committing ink to paper. You can verify whether the color profile of the document is suitable for a specific printer or monitor
and avoid unwanted results.
