Colour management in IPDS mode

Input profiles

For DeviceRGB and DeviceCMYK, the operator can specify which input profile must be used. The input profile can be a normal input profile, a device link profile or "none".

The input profiles that are available in the data stream cannot be overruled in transaction mode.

Output profiles

Output profiles are handled via the media catalogue of PRISMAsync. An output profile can be configured for each combination of media family and halftone.

Calibration of the combination of media family and halftone is done in the DP mode.

The user can select the render intent to be used for DeviceCMYK and DeviceRGB. The output intent is the same for both DeviceCMYK and DeviceRGB.

When an output profile is available in the data stream, the output profile can be used or ignored. The used output profile depends on the media family. In the Settings Editor, you can configure the output profile for each media family.

Black preservation

When you use the setting "black preservation" the following two both apply:

  • For both PDF files and IPDS data streams, the system is configured to print B/W when colours are specified in RGB with R=G=B.

  • For both PDF files and IPDS data streams, the system is configured to print B/W when colours are specified in CMYK with C=M=Y.

The system can be configured to print B/W for PDF separation "All". If you want to have black it is advised to let the application generate DeviceGray.

B/W printing

The system can be configured to print B/W only. You can configure the system via the set-up or via the data stream.

Colour flow charts

The overall colour flow chart for transaction mode:

The output data determines which of the following colour flow charts must be used:
