It is difficult to reproduce all colors on a computer screen. Everyone understands that it is actually impossible to display the image on paper on the screen without deviation, because the colors on the screen and the paper are completely different. Physical phenomenon. The color display of different brands of screens can be very different, and the temperature of the screen is another factor; the color of the display may be different after the same screen is turned on for several hours, and the aging of the hardware also affects the stability of the color display; the screen Phosphorus will decline with time. Finally, the external light sources of your work environment will also work, because when they are projected on the screen, they will mix with the colors emitted by the screen. The color temperature of the white point of the unadjusted screen is higher, and the color temperature is between 8000 and 9500K, which is obviously blue. In order to make the color between the screen and the finished product or printed product have a close effect, you should set the white point of your screen (WhitePoint) to the color temperature of the indoor bulb when you look at the color. And set the appropriate gamma value (Gamma) purpose is to adjust the contrast displayed on the screen to be consistent with the drafting or printing. The working steps of screen calibration are as follows: (1) Fix the light at the working position first, or have a standard color light box for color matching. (2) Start the screen and warm up for at least 30 minutes, so that the picture tube of the screen reaches a stable state. (3) Turn off the desktop pattern, and change the background of the screen to medium gray, so as to avoid the interference of the background color. (4) Start the screen calibration software. (5) Follow the software instructions to adjust the light and darkness and contrast of the screen, use tape to press the system or lock it with the software. (6) Select the white bit color temperature and contrast value, usually the requirements for printing WhitePoint is 5000K and Gamma is 1.8. (7) Hold the colorimeter or spectrophotometer at the specified position on the screen. (8) Follow up and store the measured data and ICCProfile. The above are the steps for general screen calibration. The following explains the actual working situation. First, use AppleClolrSync's DefaultCalibrator, which is a free and simple screen calibration tool that helps you to calibrate the gamma and white point of the screen. The method of use is very simple, as long as you follow the instructions of the software, because the single * eye observation to correct, the accuracy will be poor, if you want more accurate screen calibration, you may need some equipment, these equipment include colorimeter, It uses an instrument attached to the screen to measure the color of the light emitted by the screen. The screen calibration software commands different colors on the screen. The color emitted by the color measurement screen is sent back to the computer, and the actual measured color is compared with the color that should display the ideal color, so that you can adjust the color temperature and gamma settings to obtain a certain set of goals. Finally, how to verify whether the color and darkness of the screen display are appropriate, teach you a simple method, open a blank window on the screen, then put a piece of white paper under the color light source, and then use a card to open two Use a card to observe the color and darkness of the two holes. If the color temperature is not correct, you can pull the color temperature control in the software to correct it. If the darkness is not correct, you must change the intensity of the light source, so you need to have adjustable light and dark The light box is easier to get the desired effect. If you want a more accurate reading, you can use the easy-to-use key-type light meter to measure the white level on the screen and see if the white paper reading under the color light source is consistent, and the color temperature can be measured with a color temperature meter.
