238 Corel Painter X3 Getting Started Guide

However, calibration and profiling are complex and usually require a special calibration

device and specialized software. Furthermore, improper calibration may do more harm

than good. You can find additional information about monitor calibration and custom

color profiles by researching color-management techniques and products. You can also

refer to the documentation that was provided with your operating system or monitor.

Should I assign or convert color profiles?

In deciding whether to assign or convert a color profile, you should first consider the

results that each action produces. When you assign a color profile in Corel Painter, the

color values, or numbers, in the document do not change. Instead, the application

simply uses the color profile to interpret the colors in an image. However, when you

convert a color profile, the color values in the document change. Instead of assigning a

color profile, the application translates one color profile to another. Converting a color

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.
