-Evaluation of Monitor Calibration and Profile Quality
After calibrating and profiling your monitor with Huey, it should look essentially neutral in color and have smooth contrast. Depending upon the types of files you're viewing, such as photographs, computer games, or office documents, check light, medium, and dark areas of the screen to make sure they look neutral and don't have a strong color cast. Make sure any gradients or blends are smooth.
You can perform a more comprehensive test of your Huey monitor profile if you have Adobe Photoshop or another application that is able to display photos (bitmapped images) using ICC profiles. Use the following steps to view the images with and without the monitor profile.
1) To turn off the monitor profile in Photoshop, select View > Proof Setup > Monitor RGB. The monitor profile will be off if View > Proof Colors is checked. To turn the profile on and off, uncheck and then recheck Proof Colors.
2) Compare with an image. Open an image in Photoshop and compare it on-screen with a print. Select an image that you have printed with a printer profile you know is good. If the print is viewed in balanced illumination (daylight or 5000 K illumination), the image on-screen should look the same. If viewed in home incandescent, office fluorescent, or any other lighting that isn't neutral, the printed image will be off and won't match the screen exactly.
3) Create a gradient. In Photoshop, use the gradient tool to make a gradient from black (RGB = 0 0 0) to white (255 255 255). Examine the gradient with the monitor profile on and off (see above instructions). The gradient should be smooth from highlight to shadow.
4) Check shadow definition. Create a series of rectangles with RGB values of 0 0 0 (black), 8 8 8, and 12 12 12. If your monitor is properly calibrate and profiled, you should be able to see a difference between the three rectangles.
