    PANTONE colours. To complicate matters, a single page may contain a mix of RGB, CMYK, and spot colours. The ES3640e MFP allows users to control the printing of these mixed-colour documents with features that apply specifically to RGB, CMYK, or spot colour data.
  • Page 16 The following diagram illustrates the print options in the ES3640e MFP colour management process that affect colour data conversions. You can access these print options when you send a print job to the ES3640e MFP. Most of these options and settings are described in subsequent sections of this chapter.
  • Page 17 You can specify settings for the following options by selecting print options when you send a job to the ES3640e MFP. Some can also be set as defaults by the administrator during Setup or using ColorWise Pro Tools. Settings specified using print options override the defaults.

(Default set at Setup or with ColorWise Pro Tools) Rendering Style Applies a ES3640e MFP colour rendering dictionary (CRD) to RGB data (see Photographic/Presentation/Relative page 1-5), or to any incoming data with a PostScript source colour space Colorimetric/Absolute Colorimetric definition, including CMYK.

  • Page 19: Rendering Style

    The Rendering Style option specifies a CRD for colour conversions. To control the appearance of images, such as prints from office applications or RGB photographs from Photoshop, select the appropriate Rendering Style. The ES3640e MFP allows you to select from the four rendering styles currently found in industry standard ICC profiles.

  • Page 26: Rgb Separation

    The RGB Separation option determines how RGB colours (as well as Lab and XYZ colours) are converted to CMYK. The name of this option is meant to be descriptive, since the option defines the colour spaces that will be used by the ES3640e MFP to “separate” the RGB data into CMYK values.

  • Page 27: Output Profile

    1-13 Managing colour on the ES3640e MFP Output profile An output profile consists of a profile for your printer, describing its colour characteristics. In certain cases, you may want to customize the default output profile using the ColorWise Pro Tools Color Editor to achieve particular colour effects (see page 3-9).

    Although most users’ needs are met by the default calibration set, the Fiery allows you to choose a calibration set to customize calibration for specialized jobs. Calibration allows you to: • Maximize the colour reproduction capabilities of the ES3640e MFP. • Ensure consistent colour quality over time. • Produce consistent output across Fiery servers.

  • Page 38: Scheduling Calibration

    Because printed output from the printer is very sensitive to changes in temperature and humidity, the ES3640e MFP should not be installed near a window or in direct sunlight, or near a heater or air conditioner. Paper is sensitive to climate changes as well.

The computer may also prompt you that it is necessary to calibrate the spectrophotometer.

  • Page 99 A-7 Colour Measurement Instruments 7. Click Utilities. The Utilities dialog box appears. To view version and serial number information, click Show DTP-41 Info. When you are finished, click Done. 8. Click Calibrate DTP-41. The Instrument Calibration dialog box appears. 9. If you have not already done so, remove the shipping spacer from the measurement page slot.

    A-9 Colour Measurement Instruments Using the X-Rite DTP32 densitometer ColorWise Pro Tools are designed to work with the X-Rite DTP32 reflection densitometer, which feeds colour measurements to the Fiery automatically. Measurements from other densitometers can be input using a simple ASCII file format (see Appendix Setting up the DTP32...

For a Windows computer, insert the 8-pin mini-DIN end of the interface cable into the 9-pin DB9 Connector cable adapter. Insert the 9-pin end into the COM1 or COM2 port on the computer and tighten the screws. If the available port on your computer is 25-pin, you must use the 8-pin-to-25-pin adapter.
