HP Latex 3000 Series

●
De
fault status indicates that this substrate has never been calibrated, and therefore no reference state
is dened.
●
Done status indicates that a color calibration has been performed successfully on this substrate, the
reference state is dened and still up to date.
●
Obsol
ete status indicates that the printer status has changed since the reference was dened, so a new
calibration must be done in order to maintain color consistency.
Color calibration is based on the color measurement of printed color patches, using the embedded
spectrophotometer. Some characteristics of substrates, such as surface roughness or transparency, may
make reective color measurement of some substrate types very inaccurate. Color calibration of these
substrates may fail or produce unacceptable printing results.
TIP: If color calibration fails at the rst attempt, it is worth trying again.
To delete the reference for a given substrate, so that you can create a new reference for that substrate, you
must reset the color calibration. In the Internal Print Server, select Substrate > Color calibration > Reset.
You should calibrate a substrate type before creating its color prole; however, you can later recalibrate
without needing to recreate the color prole.
Color consistency between dierent HP Latex 3000 printers
It is possible to print consistent colors on dierent HP Latex 3000 printers by exporting a calibrated substrate
preset (see Substrate presets on page 80) from one calibrated printer to another. This process ensures that
both printers use the same color references.
1. Create the reference for the rst printer: do at least the rst color calibration with the substrate in
question.
2. Export the substrate preset from the rst printer. The reference is also exported.
3. Import the substrate preset to the second printer.
4. Perform color calibration with the same substrate for the second printer, to make it consistent with the
reference imported with the preset.
Now both printers have the same reference for the same substrate, and all the consecutive color calibrations
will be trying to match this reference state.
Color proles
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.
