Media
GMG ColorProof comes with predefined GMG ProofMedia for all commonly used proof printers. These media cannot be edited. You can duplicate GMG ProofMedia and use them as a template for custom media, though. For using a custom medium, you need to create a printer calibration file in GMG ProfileEditor and to add a calibration set for this printer calibration. You also need a color profile for the custom medium.
For each media type, for example, GMG ProofMedia premium semiMatte 250, you can define available media sizes. You cannot assign a specific media size to a specific printer, you can only set up media sizes globally for all printers. When closing the dialog box, GMG ColorProof validates the media sizes for the selected printers. Only sizes that are supported by the selected printer are displayed in the Media list and can be selected for a job.
You can set up or remove custom media sizes. Standard media sizes such as roll 13'' or A4 cannot be deleted.
Automated Media Management
Some printers such as HP Z
HP Z: The GMG ColorProof database holds all HP Z printer media that are currently available on the market. You can also set up custom media in GMG ColorProof. Synchronization works in two directions, from GMG ColorProof to the printer and vice versa.
Canon imagePROGRAF: For enabling the synchronization, it is required that imagePROGRAF Media Configuration Tool provided by Canon is installed on the computer. (The tool is not included in the GMG ColorProof setup. For further information, please (see "Exchanging Media Information between Printer and Software").)
Already existing and new custom printer media are downloaded automatically via TCP/IP from the GMG ColorProof program onto the printer.
If a print medium cannot be loaded from the program to the printer, it is listed in the Info pane, on the right side of the main window, also informing you on the reasons why the download failed (for example, no parent paper has been defined for a certain print medium as illustrated in the following screenshot).
Only HP Z: Printer media information is also uploaded from the printer into the GMG ColorProof database. The information, which print modes are supported by which printer medium is also uploaded. This way, you have always a broad range of media available for your printers. However, We recommend using GMG ProofMedia for best proofing results. Please note that GMG ColorProof supports only the most important print modes for these printers that will either result in an excellent quality (for proofing or production) or in a fast print speed. By selecting the appropriate print mode, print quality and speed are up to your preferences or requirements.
