Epson Stylus Pro 4900, 7900, 9900
If not mentioned otherwise, the Epson Stylus Pro WT7900 uses the same color management technology and supports the same features as the Epson Stylus Pro 4900, 7900, 9900 series. For further information, see also Comparison of Printer Drivers for Epson Stylus Pro x900 Printers.
Printer features
- These high-quality printers made by Epson print a very large color space by using Epson UltraChrome HDR Ink with additional Orange and Green inks. Due to the light gray inks, very smooth gradations can be achieved in the highlights.
- Depending on the Epson print mode, either Photo Black (PK) or Matte Black (MK) are used. [Preinstalled print modes based on the GMG Driver state the used ink set in the print mode name.]
- GMG Driver print modes for compatibility with Epson x880 series calibrations and profiles: With these 4c and 8c print modes, you can use all GMG and custom MX3 printer calibrations and MX4 proof profiles you might have in use for printers of the Epson Stylus Pro x880 series. Available Compatibility Mode print modes are: GMG Driver - Photo Black - 8c - 720 x 720 dpi, GMG Driver - Matte Black - 4c - 720 x 720 dpi
- Epson Driver print modes for custom calibrations and profiles: GMG also supports custom printer calibrations based on Epson Driver print modes. You can use the GMG starter kit to easily create your own printer calibration and proof profile for support of custom print media.
- The Epson Stylus Pro 4900, 7900, 9900 can optionally be equipped with an integrated measuring device (embedded SpectroProofer). Together with GMG AutoCali Wizard, printer calibration becomes very easy and fully automated. GMG AutoCali Wizard supports sheet media on Epson Stylus Pro 4900 printers. Due to the small sheet size, the test chart will be divided in two. The two test charts will then be printed and measured one after the other.
- To make the transition between different measurement conditions more convenient, GMG ColorProof has been equipped with an auto-switch for M0, M1, and M2. Reading the measurement condition from the selected calibration set or proof standard, the correct measurement mode is automatically applied.
Printer hardware settings
- For using GMG ProofMedia, select the correct media type, for example GMG ProofPaper semimatte 250, in GMG ColorProof and select Epson Proofing Paper White Semimatte in the printer panel.
- Preinstalled calibration sets support only white backing. Please make sure that you use SpectroProofer with white backing plates.
Drying times
For printers with an embedded SpectroProofer, the drying time after printing is very important for achieving correct measurement results. Different settings are recommended for different types of measurement. Drying settings can be changed in the Change Media dialog for each printer (> Media Specific Printer Settings).
| Measurement Type | Drying Method | Drying Time |
|---|---|---|
| Measuring a control strip | Air Drying | 5 min |
| Recalibrating (GMG AutoCali Wizard) | Air Drying | 5 min |
| Measuring a Full Gamut test chart | Air Drying | 5 min |
| Measuring a Gamut test chart | Air Drying | 15 min |
| Optimizing an MX4 Profile | Air Drying | 15 min |
Printer maintenance
- The nozzle status is checked by embedded sensors without using media. The check is performed fully automatically, without user interaction required.
