First, create a high simulation copy color management system
The color management of art reproduction technology refers to the management of the transfer of color space (such as scanners, displays, inkjet printers). Color management requires color information to be as consistent as possible in the process of input, processing, and output. However, the color in the process of transmission involves hardware and software that do not express the same color. Therefore, to maintain consistency and stability in the color information transfer process, standardized color management must be implemented.
The digital printing high simulation copying technology developed in this paper is a color management of high simulation copying with coated rice paper, silk enamel + new technology (Epson Stylus Pro 9800 inkjet printer) + new software (EFI color management software). .
Second, high simulation copy color management methods and steps
High-simulation copy color management should use a standard ambient light source to keep the room light constant, so that the original color of the artwork is basically the same as the screen color and coated rice paper printing color. The choice of light source should consider the following two aspects: First, a better color temperature, the basic observation lighting in the international standard is recommended as a CIED50 standardized light source that matches the spectral distribution of the daylight with a correlated color temperature of 50000K. The second is a fluorescent tube with a higher display index and an R value greater than 95% of the spectral display characteristics. The experiment uses the fluorescent tube of Germany JUS company to display the index of 97% to completely reflect the true color of the illuminated object.
(1) Color management of the scanner
One of the key aspects of high-fidelity copying of artwork is the physical scanning of the original, and all the information needed from the original is obtained from the beginning. This requires calibration of the scanner. #p#å‰¯æ ‡é¢˜#e# The purpose of scanner calibration is to correct the brightness, contrast, and black and white fields of the scanning device to ensure that the same original can be obtained for the same original when the scanner is initialized to zero. Image data. To achieve this goal, a scanner profile must be created. The calibration and profile generation of the scanner is done by means of 1T8.7/1 (standard transmission for scanning) or 1T8.7/2 (standard for scanning) standard original and scanner profile generation software. The following are the specific steps for the calibration of the scanner and the generation of the profile by means of the scanner profile generation software Scanopen.
1. Turn on the scanner and heat pipe 30 minutes in advance to ensure that the light of the lamp reaches a normal and stable state.
2. Clean the glass of the flatbed scanner stage.
3. When using the flatbed scanner, be sure to align the edge of the color card with the frame of the stage to prevent the scanned image from tilting.
4. Launch the scanning application, clear all scanner color adjustment, control and management options, set up the scanner, and record the scanner's settings in detail.
5. Open Scanopen, click "Start to generate profile", follow the prompts to select the entire color card, and then click the "Scan" button to scan the card image.
6. According to the prompts, check the "upper left corner", "upper right corner" and "lower right corner" of the color card.
7. Click the "Create Profile" button to create a scanner's ICC profile and the profile is created.
8. Load the test file and reference file: Open the color management application again, enter the scanner color management options, input the digital image obtained by the scan card, that is, the test file, and then select the corresponding reference file in the reference folder. Click the "Open" button to send the selected reference file to the color management application.
9. Create and save the configuration file: Click the "Create Configuration File" button to pop up the Save Configuration File dialog box.
