Spectrophotometer Unit SU-21

The optional Spectrophotometer Unit SU-21 includes an X-Rite color
measuring unit and Calibration White Tile. The Spectrophotometer Unit
must be mounted on an imagePROGRAF iPF6400S printer in order to
perform color calibration for third-party media. A profile of the media is
created and stored on the printer's hard drive for distribution to the
imagePROGRAF iPF6400S/8400S/9400S printer models participating in
the Canon Calibration Link system. Measurement charts for various third-
party media along with an accompanying label of the measured results can
be printed. The Spectrophotometer Unit SU-21 can be transferred from one
imagePROGRAF iPF6400S printer to another.
1. X-Rite Spectrophotometer Color Measuring Unit
The X-Rite Color Measuring Unit is a high speed, high precision color
sensor that is mounted inside the Spectrophotometer SU-21 unit. It is
compliant with the new X-Rite XRGA standard and supports switching
between tungsten and UV-Led light sources. Its unique position within
the Spectrophotometer SU-21 unit is optimized for the printing, drying,
and measuring of the calibration charts. Canon recommends that an
annual calibration of the X-Rite sensor be performed in order to confirm
its default value.
2. Spectrophotometer Calibration White Tile
The
Spectrophotometer is positioned for automatic calibration of the
Spectrophotometer. A clean tile is required for perfect calibration. Each
tile is uniquely matched to its original Spectrophotometer and must be
returned with the unit when recertification or repair is needed.
