New standards have been defined and Adobe is at the forefront of this new technology. No longer do you have to fear color management because Adobe Photoshop has taken all or at least most of the guesswork out of the equation.

While nothing is perfect the world of professional printing is more controlled. For example when you re working on a color document that is moving to press you can use a predetermined set of colors such as the Pantone Matching System. The Pantone colors come printed on special card stock. When you re looking for a specific color you choose it from the card stock and then that information is given to the press operator. This type of control even including the type of paper keeps you in charge of the process of moving from monitor to print. 18 What You ll Do Produce Consistent Color .
