Black and White in Photoshop CS4 and Photoshop Lightroom How often should I calibrate? Just as you may want to change the oil in your vehicle every 3000 miles, or wax and edge your skis to maximize their optimum performance periodically, a monitor needs the same kind of regular tune-ups and care to perform well over time. · Monitors should be calibrated every 2­4 weeks depending on the amount of usage. · For the most accurate results, be sure to let the monitor warm up for at least 30 minutes in order to stabilize before calibration is performed. · Periodic calibration will help maintain consistent color display on the monitor over time. Settings for calibration will vary depending on your output. If you are working in your own closed loop system ­ that is your own camera, printer and monitor ­ our best recommendation for most users would be to work with daylight settings, 6500 K and Gamma 2.2 as a starting point. This setting is usually best for working with Adobe 1998. If working with Piezography inks, results have often been more accurate using a D-50 or 5000 K calibration
