ADOBE PHOTOSHOP CS2 

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 Settings dialog box of any Creative Suite application. With the working space set to sRGB, any 
RGB graphics you create will use sRGB as the color space. 

When working with images that have an embedded color profile other than sRGB, you should convert the image’s 
colors  to  sRGB  before  you save the  image for  use on the  web.  If  you want the  application to automatically  convert the  
colors to sRGB when you open the image, select Convert To Working Space as the RGB color management policy. 
In Photoshop and InDesign, you can also manually convert the colors to sRGB using the Edit > Convert To Profile 
command. 

When you export Portable Document Format (PDF) files, you can choose to embed profiles. PDF files with 
embedded profiles reproduce color consistently in Acrobat 4.x or later running under a properly configured color 
management system. For information about color management in Acrobat software, see Acrobat online Help. 

Keep in mind that embedding color profiles increases the size of PDF files. RGB profiles are usually small (around 
3K); however, CMYK profiles can range from .5 to 2 MB. 

Many  web browsers do not  support color  management. Of the  browsers  that  do  support color  management, not  all  
instances can be considered color-managed because they may be running on systems where the monitors are not 
calibrated. In addition, few web pages contain images with embedded profiles. If you manage a highly controlled 
environment, such as the intranet of a design studio, you may be able to achieve some degree of HTML color 
management for images by equipping everyone with a browser that supports color management and calibrating all 
monitors. 

You can approximate how colors will look on non-calibrated monitors by using the sRGB color space. In Adobe 
GoLive, you can also preview how colors will look in different browsers using options in the View palette. (See “To 
preview how colors will appear in a web browser” on page 261.) However, because color reproduction varies among 
uncalibrated monitors, you still won’t be able to anticipate the true range of potential display variations.
