Color management system

There is no device in a publishing system that can translate a variety of colors are viewed accurately with the human eye. Each device operates in a particular color space that can produce a range, or overall color.

Color model to determine the relationship between values and the absolute color space defines the meaning of those values as colors. Some color models (such as the CIE L * a * b) still has a color space, their space was directly related to how humans see color. This model will be explained as a standalone device. Other color models (RGB, HSL, HSB, CMYK, etc.) can have different color spaces. Because the model is different from the color of each space-related or device, they are depicted as color depends on the device.

As a result of differences in color space, there was a shift in the view your documents on different devices. Color variations can result from differences in the source image; how to set the color of software applications, print media (any type of paper affect the type of print), and other variations.

What is the color management system?
Problem color matching with the results of the various software and use the color space. One solution is to have a system that interprets and translates color accurately between devices. Color management system (Color Management System / CMS) with the color space has been created with the same color space where color will be printed, and make the necessary adjustments to represent the colors to be consistent on different devices.

Color management system translates colors with the color profile support. Color profile is a mathematical description of the device color space. For example, scanner profile tells the color of your management system scanner to "see" color. Adobe color management using ICC Profile, the format specified by the International Color Consortium (ICC) as a cross-platform standards.

Since no single color translation method is ideal for all types of images, color management system provides a choice of rendering intents, translation or method, so you can apply the appropriate method for a particular graphic element. For example, the color translation method that preserves the right in the relationship between color photos of wildlife that can change the color.

Note: Do not confuse color management with color correction. Color management system will not properly stored images with tonal or color balance problems. This provides an environment where you can evaluate images reliably in the context of your final results.

Do you need color management?
Without color management system, could be your color specifications are dependent on the device. You may not need color management if the production process is tightly controlled for one medium only. For example, you or your print service provider can customize the image CMYK color and determine the value to be known, in this particular set of printing conditions.

Color management value increases when you have more variables in the production process. Color management is recommended if you anticipate re-using color graphics for print and online media, using various types of devices in a single medium (such as printing), or if you manage multiple workstations.

You will benefit from a color management system if you need to complete one of the following: Get a predictable and consistent color output in several output devices including color separations, desktop printers, and your monitor. Color management is very useful to adjust the color with a relatively limited devices overall, such as four-color printing process.

Perform Proof Color (first) a document on your monitor's color by doing it simulates a particular output device.

Evaluate accurately and consistently to incorporate color graphics from different sources if they also use management. Send documents to a variety of colors and media devices without having to manually adjust the colors in the original document or graphic. This is especially useful when creating an image that will ultimately be used both in print and online. Print color correctly to the color of an unknown device, for example, you can store documents online to be duplicated consistently color-demand anywhere in the world.
