profile does more than affect the display of colors — it produces irreversible changes to the colors in the

document.

The best practice is to choose a working color space, such as sRGB, when you create an image and to use

the same color profile throughout your workflow. You should avoid assigning and converting color profiles.

However, you may encounter scenarios that require you to switch to a different color profile.

For example, if you receive a file from someone, and no color profile is embedded in the file, you should

assign a color profile to the file. In this way, you can retain the file’s original color values.

You should choose the conversion option only if you are preparing the file for a specific output, such as a

printer. After the data has been changed to accommodate the destination profile, conversion back to the

original color profile is often not suitable.

What is a rendering intent?

A color management system can perform effective translation of colors from the source to multiple outputs.

However, when matching colors from one color space to another, a color management system may be

unable to match certain colors. These “out-of-gamut” colors can dramatically change the look of the image,

depending on how they are interpreted by the color management system. Fortunately, you can choose a

rendering intent to instruct the color management system how to interpret the out-of-gamut colors. The

rendering intent that you choose depends on the graphical content of the image.

This is an example of three types of images and their corresponding rendering intents.

• Perceptual — Choose this rendering intent for photographs and bitmaps that contain many out-of-

gamut colors. The overall color appearance is preserved by changing all colors, including in-gamut

colors, to fit within the destinations range of colors at the destination. This rendering intent maintains

the relationships between colors to produce the best results.

• Saturated — Choose this rendering intent to produce more concentrated solid colors in business

graphics, such as charts and graphs. Colors may be less accurate than those produced by other

rendering intents.

• Relative Colorimetric — Choose this rendering intent for logos or other graphics to preserve original

colors. If a match is not found for the source colors, then the closest possible match is found. This

rendering intent causes the white point to shift. In other words, if you are printing on white paper, the
