12 - Rendering Intents

When you convert a sRGB or Adobe RGB file into a printer profile, you have to select a rendering intent.

Why?

Your photograph may have colors that can't be reproduced by the printer.

What you see on your monitor, may not be what you're going to get as a print.

Your monitor has more colors, with greater saturation, than does a piece of photography paper.

Colors that can't be reproduced are called out-of-gamut colors.

The gamut is the area of the color space that can be reproduced.

Rendering intents decide what to do with the out-of-gamut colors.

Rendering intents may:

1) Convert out-of-gamut colors into reproducible colors.

2) Remove, or clip, the out-of-gamut colors.

Perceptual and Relative Colorimetric are the most common rendering intents.

Scroll down, or click here.

Try Relative Colorimetric first.

  What It Does Advantages Disadvantages Best For
Perceptual

All of the colors, in-gamut and out-of-gamut, are uniformly compressed.

The compression maintains the relationship between the colors in the file, so the printed photograph looks the same as the on-screen photograph—overall.

However, on an individual color level, all of the colors will have changed.

#1

In-gamut colors are changed, as well as out-of-gamut colors are changed.

#2

To move out-of-gamut colors into the gamut of the output device, the colors are desaturated.

1) When many colors will be out-of-gamut.

2) When there are areas with highly saturated colors.

Relative Colorimetric

Each out-of-gamut color becomes the last in-gamut color.

All of the in-gamut colors are left the same.

The out-of-gamut colors are changed to the last in-gamut color.

1) When there are few colors that will be out-of-gamut.

2) When there are few areas with highly saturated colors.

3) May be useful for B&W

Black Point Compensation

In Photoshop (not available in Photoshop Elements), select Black Point Compensation.

Your monitor has a darker black than does photography paper.

The Black Point Compensation feature adjusts for this difference.

The Perceptual rendering intent doesn't use this feature, so having the feature selected is of no consequence.

Relative Colorimetric does use this feature.

Next, there's more about soft proofing.
