HP Designjet T1200 User Manual

NOTE:If you protect a roll, then later unload the current roll and load a new one, the new roll
remains protected. You are protecting the roll number, not one specific roll of paper. That roll number
will remain protected until you cancel the protection.
TIP:If you print without specifying a roll number or paper type, you will not be able to print on any
protected roll.

Introduction
Your printer has been engineered with advanced hardware and software features to ensure
predictable and dependable results.
●Color calibration for consistent colors.
●One gray and two black inks provide neutral grays on all paper types.
●The Photo Black ink provides pure blacks when printing on photo papers.
●Color emulation of other HP Designjet printers.
How colors are represented
All devices that display color use a color model to represent color in numerical terms. Most monitors
use the...

You can check the color calibration status of the currently loaded paper at any time by pressing the
View information key on the front panel. The status may be one of the following:
●PENDING: the paper has not been calibrated.
NOTE:Whenever you update the printers firmware, the color calibration status of all papers is
reset to PENDING.
●OBSOLETE: the paper has been calibrated, but the calibration is now out of date because a
printhead has been replaced, and should be repeated.
●DONE: the paper has been...

Color management from printer drivers
Color management options
The aim of color management is to reproduce colors as accurately as possible on all devices: so that,
when you print an image, you see very similar colors as when you view the same image on your
monitor.
There are two basic approaches to color management for your printer:
●Application-Managed Colors: in this case your application program must convert the colors of
your image to the color space of your printer and paper type, using the ICC...

NOTE:This option is available only when printing an HP-GL/2, PostScript or PDF job. It will work
correctly only when printing on plain, coated or heavyweight coated paper.
●In the Windows HP-GL/2 or PostScript driver dialog: select the Color tab, then Printer
Managed Colors, then select Printer Emulation from the Source Profile list. You can then
select from the Emulated Printer list.
●In the Mac OS Print dialog (T770, T1200): select the Color Options panel, then Color
Management > Printer, then select...

●The lightness slider simply makes the whole print lighter or darker.
●The color sliders can be used to fade or emphasize each of the primary colors in the print. The
primary colors may be red, green and blue; or cyan, magenta and yellow; depending on the
color model used in the image.
The Reset button restores each slider to its default central position.
Printing in grayscale
You can adjust the gray balance of your print in similar ways under Windows and Mac OS:
●In the Windows driver dialog: select the...

●The lightness slider simply makes the whole print lighter or darker. This slider is available in the
same window as the other grayscale controls, except under Mac OS X 10.4, where it is available
by selecting Lightness and Hue.
●The zone definition sliders can be used to define what you mean by highlight, midtone and
shadow.
●The other controls for highlight, midtone and shadow can be used to adjust the gray balance of
highlights, midtones and shadows respectively.
The Reset button restores each control...

Emulation not only provides the closest match that can be achieved on your printer; it also gives clear
information on how close the emulation is to the original spot color. See 
Printing PANTONE swatch
books on page 74.
Color emulation
Your printer can emulate the color behavior of other devices: RGB devices such as monitors, and
CMYK devices such as presses and printers.
You can set color emulation in the following ways:
●In the Windows PostScript driver dialog: select the Color tab, and Printer...
