You should always calibrate a device before creating a profile for it. 4 Using Adobe Gamma you adjust the brightness and contrast phosphors color characteristics gamma color contrast and white point extreme highlight of the monitor. You adjust these settings to calibrate your monitor. Adobe Gamma uses those settings to create an ICC monitor profile that defines your monitor s color space for working on graphics. 12 Producing and Printing Consistent Color The document s embedded color profile does not match th current RGB working space. To produce consistent color you define the color space in which to edit and display RGB images and in which to edit display and print CMYK images. This helps ensure a close match between on-screen and printed colors. 3081 LESSON 12 Producing and Printing Consistent Color In this lesson you ll learn how to do the following Define RGB grayscale and CMYK color spaces for displaying editing and printing images.
