● Whenever a new substrate type is introduced that has not yet been calibrated. ● Whenever you notice excessive color differences between prints. Such color differences are mainly caused by aging and wear of the printheads, installing new printheads, and changes in substrate characteristics between one roll and another. You can check the color calibration status of your substrate by pressing on the front panel. ● Recommended status indicates that this substrate has never been calibrated. In this case, the factorydefault color tables will be applied to print jobs, as there is no reference state defined. After one or more color calibrations have been performed, pressing the Reset button returns the status to Recommended. ● Done status indicates that a color calibration has been performed successfully at least once on this substrate, and therefore a color reference state is defined. ● Obsolete status indicates that the last color calibration may be out of date. For instance, color calibration status is set to Obsolete whenever a printhead is replaced. The color reference state remains defined. ● N/A indicates that this substrate cannot be color-calibrated. NOTE: Generic substrates cannot be color-calibrated, although such substrates may be suitable for color calibration. You can color-calibrate clones of most generic substrates. TIP: If color calibration fails, it is worth trying again. TIP: If the first color calibration of a new substrate fails, press the Reset button before trying again. ICC profiles Color calibration provides consistent colors, but consistent colors are not necessarily accurate. For instance, if your printer prints all colors as black, its colors may be consistent but they are not accurate. In order to print accurate colors, it is necessary to convert the color values in your files to the color values that will produce the correct colors from your printer, your inks, your print mode, and your substrate. An ICC profile is a description of a printer, ink, print mode, and substrate combination that contains all the information needed for these color conversions. These color conversions may be performed by your Raster Image Processor (RIP), if it offers that possibility; they are not performed by the printer. For further information on the use of ICC profiles, see the documentation for your application software and for your RIP. In addition to the ICC profiles used for printing, you may wish to calibrate and profile your monitor (display device), so that the colors you see on the screen relate more closely to those that you see on your prints. 82 Chapter 4 Substrate settings ENWW

characteristics between one roll and another.
You can check the color calibration status of your substrate by pressing
on the front panel.
●
Recommended
status indicates that this substrate has never been calibrated. In this case, the factory-
default color tables will be applied to print jobs, as there is no reference state defined. After one or
more color calibrations have been performed, pressing the
Reset
button returns the status to
Recommended.
●
Done
status indicates that a color calibration has been performed successfully at least once on this
substrate, and therefore a color reference state is defined.
●
Obsolete
status indicates that the last color calibration may be out of date. For instance, color
calibration status is set to Obsolete whenever a printhead is replaced. The color reference state remains
defined.
●
N/A
indicates that this substrate cannot be color-calibrated.
NOTE:
Generic substrates cannot be color-calibrated, although such substrates may be suitable for
color calibration. You can color-calibrate clones of most generic substrates.

ICC profiles
Color calibration provides consistent colors, but consistent colors are not necessarily accurate. For instance,
if your printer prints all colors as black, its colors may be consistent but they are not accurate.
In order to print accurate colors, it is necessary to convert the color values in your files to the color values
that will produce the correct colors from your printer, your inks, your print mode, and your substrate. An ICC
profile is a description of a printer, ink, print mode, and substrate combination that contains all the
information needed for these color conversions.
These color conversions may be performed by your Raster Image Processor (RIP), if it offers that possibility;
they are not performed by the printer. For further information on the use of ICC profiles, see the
documentation for your application software and for your RIP.
In addition to the ICC profiles used for printing, you may wish to calibrate and profile your monitor (display
device), so that the colors you see on the screen relate more closely to those that you see on your prints.
