That is, their unique color range and colors reproduced are mapped. Color management software performs the translation between the initial color depiction or sample and the "fingerprinted" colors of these output devices. While color management doesn't assure a color match between devices, it can allow more control over the color reproduction method when process changes occur. While output devices and printing systems can benefit from color management methods, what is the return on investment for a printing company and its workers? One of the benefits of managing color output is to lower the cost in achieving "good color" in a production environment. Inaccurate color results usually in a higher rate of job rejection and requires costly reprinting. This raises production and labor costs and lowers profit margins. There are added benefits to color management with production personnel who need to make fast and accurate color changes to a job, based solely upon what they see on a computer monitor. With proper color management, timely corrections can be visualized on the monitor and rendered directly to the print process. Equipment "The necessary tools one needs to provide a color-managed workflow," said Jeff Burton, SGIA's digital printing analyst, "include a colorimeter (designed to calibrate a monitor) and a spectrophotometer (designed for reading colors and interpreting the color reading into standard color space values). Spectrophotometers can either be handheld, capable of reading values in strip form or a strip reader, which automates the color measurement process in a production environment." Burton continued, "Inkjet printers by themselves have no innate knowledge of color or correct output. When purchased they are either bundled or bought in conjunction with raster image processing (RIP) software that translates the electronic file into a format the machine can utilize and print with. Usually, the RIP software has the capacity to modify the ink control of the printer and to amend or adjust the color of incoming and outgoing image files." Few manufacturers are beginning to bundle the hardware (built-in spectrophotometer) and the software necessary for a color-managed workflow, but these are still in the minority. "For the most part, third-party spectrophotometers are a necessary part of 'profiling' media for better color output," Color management equipment can be broken down into the fol- said Burton.

If a RIP is not used, there are software solutions provided by the color management retailers directly." Visit SGIA at SGIA.org http://www.SGIA.org
