1 Preset of color management parameters
The color management dialog can be called up by selecting the Color Management (Management) command in the Edit menu of CorelDraw, Mac OS 9 and x) or the Color Management î—¤Color Management command î—¤Pc version of the Tools menu. This dialog is unique in its style, with a set of icons and arrows depicting CorelDraw's color management workflow (shown in Figure 1).
This dialog is used in a slightly different way than most other dialogs. If you move the cursor around it, the cursor will change from "small hand" shape from time to time; if the cursor is temporarily paused in an element, the comment information about the element will be displayed, and each icon has a corresponding description. . Similarly, each arrow has a corresponding comment. These arrows can indicate whether color management is implemented in the direction indicated. As shown in Figure 1, select arrow 1 to turn on monitor compensation, select arrow 2 to turn on color management for the composite printer, select arrow 3 to turn on color management for the color separation printer, and select arrow 4 to make your monitor simulate a composite printer Output, select arrow 5 to make your monitor simulate the output of the color separation printer, select arrow 6 to make your composite printer simulate the output of the color separation printer, select arrow 7 to open the color management of the imported file, select the arrow 8 indicates that color management of the exported file is turned on, and selection arrow 9 indicates that color management of all images obtained from the scanner or digital camera is turned on.
To select a profile, you can click on the black triangle arrow below a device or feature icon to bring up a menu listing the available profiles. Both Apple and PC CorelDraw search for ICC profiles along specific paths. In addition, you can also try to click on each icon to see if the corresponding "Advanced Options" dialog box can be called up, but only three of them have advanced options, and the rest do not.
The following is a detailed description of each element in the dialog and the necessary advanced options. We will first introduce the icon in the center, then introduce the monitor icon, and then introduce the remaining icons in a clockwise direction.
1) Internal RGB settings
The centrally located icon represents the RGB editing color space used by CorelDraw. Its default state is inactive because its profile is the monitor profile, so although import, export, printer, and scanner conversions can be performed as usual, no display compensation is done.
It is worth emphasizing that internal RGB is assumed. The RGB source properties file works for all RGB objects, including the placed object and the original CorelDraw object. When saving a CorelDraw document, it does not embed this property file in the CoreIDraw document, so you need to select a property file and always use it. If other people also use the CorelDraw document, and that person also needs precise color management, you must tell them which feature file is selected for the internal RGB. If you change the internal RGB properties file when editing a CorelDraw document, the color characteristics of all RGB objects will immediately change according to the new properties file. But this is not a color conversion, it is just a change related to the assumed property file, so the RGB value of the RGB object does not change, but the meaning and appearance of the color does change.
2) Display settings
Here you can choose to display the profile, here we select the ICC file of the display we made ourselves.
Click on the display icon to bring up the advanced display settings. If you have previously activated an arrow pointing to the display icon by a composite color printer or color separation printer, the "Highlight the color beyond the print gamut" option in the dialog box becomes optional. As the name implies, if the color of the analog display cannot be printed on the output device, CorelDraw will display those colors with a special warning color.
If we want the screen to display the results of a simulated composite printer, then we select arrows 2 and 4. If we want the screen to display an analog color separation printer, we choose arrows 3 and 5. If the arrow is from the middle RGB icon, CorelDraw only performs display compensation processing for the internal RGB to display property file. [next]
3) Composite printer settings
This can be either an RGB profile or a CMYK profile. CorelDraw supports pure RGB to RGB processes and also supports CMYK to RGB processes. Here we can choose the printer ICC file we made earlier. To have the composite printer simulate the effect of the color separation printer, simply click on arrow 6 and you can cancel the activation of arrow 2.
4) Import/export settings
By default, there are no properties files selected for this icon. Click the icon with your mouse to bring up the Advanced Import/Export Settings dialog. The first thing to note is that this dialog only works for RGB objects. When guiding a CMYK object, CorelDraw ignores its embedded property file and changes it to the feature file of the color printer.
The purpose of the Advanced Import/Export Settings dialog is to control how the profile is used during the import and export process. We recommend using the first option in the Import and Export sections separately, that is, the Import section uses the embedded ICC profile option and the Export section uses the Embed internal RGB profile option.
5) Scanner / digital camera settings
The profile you selected here will be the source profile for the image you get from the Get Image command in the File menu. If the internal RGB and scanner/digital camera options are set to different profile files, all images obtained with the Get Image command will be converted to the internal RGB color space.
6) Color separation printer settings
This option only covers the CMYK profile, where we can choose the ICC profile of a specific press that we have made. The profile you selected here will be used as the source profile for all CMYK objects. [next]
2 print
In the preset dialog box of the color management parameters, we set the ICC profile for each element. The color separation printer is set to the ICC of our special printer. The composite color printer is set to the ICC of our printer. The display is set to our display. ICC profile.
If we want to print with a printer, choose arrow 2, if we print with a press, choose arrow 3. If we want to simulate the printing effect of the press with a composite color printer, select arrows 3 and 6, then arrow 2 will Cancel automatically.
The Separate Print option in the Print dialog box determines whether the color search is converted to a separation or composite printer.
There are two options in the miscellaneous î—¤Misc tab in the Print dialog that are easily overlooked.
The first option is "Apply ICC Profiles". In the following two cases, the default state of the option is the selected state: the arrow in the color management dialog box that points to the composite color printer icon by the internal RGB icon is activated, and the Separation Print option is not selected; activated The arrow in the Color Management dialog box that points to the Separation Printer icon by the internal RGB icon, and the Separate Print î—¤Print separations option is selected.
The second is to print out the RGB color, you must pay attention to the "output color bitmap is" pop-up menu. Although you have selected an RGB profile for the composite color printer and it has appeared below the application ICC profile option, if you have not selected the output color bitmap as î—¤Output color bitmaps as pop-up menu "RGB" In one case, the image will be converted to CMYK or grayscale color mode. [next]
3 Summary
CorelDraw encourages us to work entirely in CMYK color mode to enable effective color management of the screen preview and proofing process. It successfully manages colors in the process of outputting files in specific formats based on color management parameters and some concise rules. You can print CMYK color images on an RGB printer, but the original CorelDraw object in CMYK mode does not necessarily match your expectations.
Overall, it is easier to output color-managed content with CorelDraw, but color management of CorelDraw's own documents is cumbersome. The only way we can use is to manually record which RGB they used at the beginning of the creation. And CMYK's profile.
