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. Generating color profiles with the 360 or 370 printer It is possible to create an ICC profile automatically for a given substrate and print mode, when adding or editing a substrate. See Add a new substrate on page 92 and Modify a substrate preset on page 91. After pressing the Create ICC profile button the following process takes place: 1. A profiling test chart is printed on the loaded substrate using the selected print mode. 2. The printed test chart is measured with the HP Embedded Spectrophotometer. 3. The color measurements are related to the target colorant values by the printer's firmware to generate the ICC profile. 4. The ICC profile is stored in the substrate preset for that print mode. NOTE: Although color profiles obtained in one particular print mode can be reused when printing with other print modes, the most accurate color reproduction can only be achieved if profiling is made with exactly the same print mode that is used for printing. For example, if you use a color profile obtained with a 12-pass standard print mode, you may see some color difference when you use it to print with an 8-pass speed print mode. 102 Chapter 4 Substrate settings ENWW

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.
Generating color profiles with the 360 or 370 printer
It is possible to create an ICC profile automatically for a given substrate and print mode, when adding or
editing a substrate. See
Add a new substrate
on page
92
and
Modify a substrate preset
on page
91
.
After pressing the
Create ICC profile
button the following process takes place:
1.
A profiling test chart is printed on the loaded substrate using the selected print mode.
2.
The printed test chart is measured with the HP Embedded Spectrophotometer.
3.
The color measurements are related to the target colorant values by the printer’s firmware to generate
the ICC profile.
4.
The ICC profile is stored in the substrate preset for that print mode.
NOTE:
Although color profiles obtained in one particular print mode can be reused when printing with other
print modes, the most accurate color reproduction can only be achieved if profiling is made with exactly the
same print mode that is used for printing. For example, if you use a color profile obtained with a 12-pass
standard print mode, you may see some color difference when you use it to print with an 8-pass speed print
mode.
