Color management

Last updated 1/14/2015

Color-managing documents for online viewing

Color management for online viewing is very different from color management for printed media. With printed media,

you have far more control over the appearance of the final document. With online media, your document will appear

on a wide range of possibly uncalibrated monitors and video display systems, significantly limiting your control over

color consistency.

When you color-manage documents that will be viewed exclusively on the web, Adobe recommends that you use the

sRGB color space. sRGB is the default working space for most Adobe color settings, but you can verify that sRGB is

selected in the Color Management preferences. With the working space set to sRGB, any RGB graphics you create will

use sRGB as the color space.

When you export PDFs, you can choose to embed profiles. PDFs with embedded profiles reproduce color consistently

under a properly configured color management system. Keep in mind that embedding color profiles increases the size

of PDFs. RGB profiles are usually small (around 3 KB); however, CMYK profiles can range from 0.5 to 2 MB.

Proofing colors

In a traditional publishing workflow, you print a hard proof of your document to preview how its colors will look when

reproduced on a specific output device. In a color-managed workflow, you can use the precision of color profiles to soft-

proof your document directly on the monitor. You can display an on-screen preview of how your document’s colors will

look when reproduced on a particular output device.

Keep in mind that the reliability of the soft proof depends upon the quality of your monitor, the profiles of your monitor

and output devices, and the ambient lighting conditions of your work environment.

Note: A soft proof alone doesn’t let you preview how overprinting will look when printed on an offset press. If you work with

documents that contain overprinting, turn on Overprint Preview to accurately preview overprints in a soft proof.

A Document is created in its working color space. B Document’s color values are translated to color space of chosen proof profile (usually the

output device’s profile). C

Monitor displays proof profile’s interpretation of document’s color values.

Soft-proof colors (Acrobat Pro)

Choose Tools > Print Production >Output Preview.

1 Choose the color profile of a specific output device from the Simulation Profile menu.

2 Choose any additional soft-proof options:

Simulate Black Ink Simulates the dark gray you really get instead of a solid black on many printers, according to the

proof profile. Not all profiles support this option.

Simulate Paper Color Simulates the dingy white of real paper, according to the proof profile. Not all profiles support

this option.
