Internal spectrophotometer (ILS)
The Interface Module is equipped with an internal spectrophotometer. This internal
spectrophotometer is sometimes referred to as an Inline Sensor (ILS). The ILS provides
the customer with an internal calibration tool that works with your print server to provide
unique calibration and profiling capabilities, which include the following:
• The ability to calibrate the digital press from the color server without manually feeding
calibration charts (also known as calibration targets)
• This is a semi-automated process:
- It is initiated by the operator
- It scans and measures targets automatically without an external
spectrophotometer
- It resets color tables to original values to maintain consistent color
• Operators can create destination or output profiles without having to scan targets
with an external spectrophotometer:
- The digital press prints color targets while the ILS measures them
- The system then develops a map so that output colors can be produced that
accurately replicate a known standard such as GRACoL or SWAP
- The mapping is written into the profile for the type of media and line screening
used
Note
These calibration and profiling capabilities are applicable to any associated print server,
including the EX Print Server and FreeFlow Print Server.
Problem solving
Clearing jams
Tip
Always ensure that all paper jams, including any small ripped pieces of paper, are cleared
before proceeding with your print jobs.
Note
Remedies differ according to the paper jam location. Follow the instructions displayed
to remove the jammed paper.
