Maintaining color integrity from monitor to printed product is essential. As a photographer in the navy I had to make sure that the computer screens were correctly calibrated to the printed product. This was done periodically to maintain color integrity. Monitors have their own color calibration but this does not always completely solve the color accuracy problem. There were many stressful moments when the photo batches from the thermal printers were sent back by the supervisor due to incorrect hues. A simple calibration would had solved this.
This is where calibration devices come in handy. These are multipurpose auxiliaries that will calibrate the monitor color while taking into account the surrounding light sources. These devices come with their own software to make calibrating the monitor to the printed product more succinct.
Some calibration devices are the X-Rite, ColorVision and Datacolor Spyder.
