Fourth, set the screen before the calibration screen

Before any device generates an ICC profile, it must do a basic calibration of the device. For example, the screen must be turned on for at least half an hour before the screen is adjusted, and its status is adjusted to the standard state of the device. MPB software has two basic functions for basic calibration and generation of device ICC files. Before making an ICC file for digital proofing, the digital proofing device must be linearized to measure the printer's ICC file in the correct density range and linearized state.

Many new screens have built-in digital controls that allow the user to set the screen to the desired White point. The result is not as accurate as in the MPB software, but it can give the MPB software a closer starting point for tuning.

Before using the MPB to tune the screen, set the White point of the screen as close as possible to the D5000. The closer the initial white point value is to the required white point value, the more accurate the screen adjustment will be. Adjust the Gamma value of the screen, Apple is 1.8, PC is 2.2. Generate a standard ICC profile file.
Adjust the screen contrast and brightness values ​​before using MPB. Set the contrast to medium (50%) and set the brightness to 80%.

Fifth, install MPB software

Open the CD and double-click on Setup.exe.

Six, rapid use of MPB software

1. Create a new file.

Set Desired Monitor Characteristics to:
White Point: D5000
Gamma: 1.8
The MPB will now show the status before the screen has not been calibrated:
White point: 9052 x,y=0.3498 0.3607
Gamma: 1.79 r,g,b=1.811 1.80 1.83

2. Execute "Start Instruction Calibration".

3. If you run for the first time, the following menu will pop up

Please enter the 7-digit password on the MPB software product box.
If the license number has been assigned to the host, the following measurement menu will pop up.

4. Align the suction of the DTP92 meter with the position identified above. Click on “Measure” and the software will automatically perform multiple cycles of calibration from white, gray, black, red, green and blue.

5. The adjusted White point is displayed here: 4867 x, y = 0.3498 0.3591

Gamma: 1.79 r,g,b=1.82 1.78 1.79
The difference between the adjusted White point and the expected White point minus should be less than 150. If this value is greater than 150, continue with "Start Instrumented /confirm/iation".
6. Store the corrected result. Select the menu File Save and name it. The naming method can be combined with the system or time name, so that it is easy to distinguish. If you want to change the Gamma and White point values, simply open the file you just saved and reselect the White point and Gamma values ​​in the drop-down menu “Dsired Monitor Characteristics”. The software automatically calculates the raw data before the adjustment according to the newly given Gamma and White point values, and does not need to re-measure.
7. Save the ICC file and select the menu File→Save ICC Profile. The following menu will pop up.
Enter the profile and manufacturer and model description here, and click Save Profile.
Macintosh computers: Save to system→Colorsync Profile folder.
Windows computers: Save to Windows/system/color directory.
Founder screen soft proofing solution is simple. The biggest feature is that after the ICC file is generated, Kodak profile editor can be used for fine adjustment. The powerful color correction function and level adjustment function of the analog extension and image processing software make it able to accurately achieve the purpose of soft proofing of the screen. In the future, we will continue to introduce its fine-tuning function and how to set it in the graphics processing software after generating the screen ICC file. ※
