●All pages must be in one or other of the follow
ing two groups (the two groups cannot be mixed in
the same nest):
◦ CALS/G4
◦ PostScript, PDF, TIFF, JPEG
● JPEG, TIFF and CALS/G4 pages with resolutions gr
eater than 300 dpi may not nest with other
pages in some cases.
How long does the printe r wait for another file?
So that the printer can make the best nest possible,  it waits after a file has been received to check
whether a subsequent page will nest with it or with  pages already in the queue. This...

What is color?
We see the world around us as steeped in color. Color is in the first instance simply an aspect of how
we experience our environment and is therefore subjective. Our color experiences are closely related to
brain activity that is triggered by s ignals that our eyes send to it. These signals undergo a complex and
highly interlinked sequence of proc essing stages that make the relationship between what our eyes emit
and what we experience anything but direct. The sign als sent by the eye...

To control the output of color imaging devices, the following color spaces are normally used:
● RGB (Red, Green, and Blue)  is the color space typically used for additive devices. A color is
represented as a combination of sp ecific quantities of red, green, and blue colorants that create
the range of colors (color gamut) in the device.
NOTE: Colors in subtractive devices  can also be controlled by using RGB data. Especially when
control over the printer’s black ink is un necessary, this is an efficient...

1.All colors
2. Computer monitor gamut
3. CMYK press gamut
Some color spaces are not device-dependent, but instead represent how a viewer sees colors, such as
CIE Lab or CIECAM02. These color spaces are de fined by the CIE (Commission Internationale de
l’Éclairage). The advantage of these spaces is that if two objects have the same CIELAB values, they
look the same when viewed under the same conditions. Values in these spaces can be obtained from
measuring the light emitted or  reflected by an object....

●CMS:  Color Management System. The software that co nverts the color information that is stored in
the input image (defined by a source profile)  into an output image that has the color space
specified by a destination profile.  Many different CMSs are on the market: in software programs,
in operating systems, and in printing software, including the Z6200 internal RIP.
● Source profile:  a description of the color  behavior of the input device
● Destination profile:  a description of the color behavior...

◦Other regional standards:  Euroscale, JMPA, Japan Color
◦ Specific CMYK device space:  for images that are coming from or going to a specific
CMYK device that has been profiled.
Color and your printer
As a creative professional, predictable and dependable results from your printer are essential to getting
your job done. Predictability is a key element of an  efficient color workflow. You need prints that match
your expectations and that generate neutral grays an d correct colors on your selected paper,...

A summary of the color-management process
To get the accurate and consistent colors that you want, follow these st eps for each paper type that you
use.
1. If the printer does not recogni
ze your paper type, add the type to  the printers list of known
papers. See 
Use non-HP paper on page 48. Typical users might add a few custom paper types
every year.
2. Color-calibrate the paper type to ensure consistent colors. Perform 
this calibration when a printer
alert recommends this calibration (typically, ev...

NOTE:You can perform all three operations in sequence , as shown. You can also choose to start
with or stop after any of the three operations. Ho wever, color calibration is performed automatically
after you add a new paper type.
Color calibration
Your printer uses color calibration to produce consis tent colors with the specific printheads, inks, and
paper type that you are using, and in your particula r environmental conditions. After color calibration,
you can expect to get identical prin ts from any...

You can start color calibration in the following ways:
●From the printer alert that recommends calibration
● From the HP Color Center: select Calibrate Your Printer
● From the front panel: select the 
 icon, then  Calibrate color
After launching calibration, the process is fully au tomatic and can be performed unattended after you
have loaded appropriate paper. The pape r must be at least 24 inches wide.
The process takes about 8 minutes and consists of the following steps.
1. A calibration test chart is...
