HP DesignJet T610 A1 User Manual

							You can rescale an image in the following ways:
●In the Windows driver dialog: select the Effects tab, then Resizing options.
◦The Print document on option adjusts the image size to the paper size you have selected.
For example, if you have selected ISO A2 as the paper size and you print an A3-sized image,
it is enlarged to fit the A2 paper. If the ISO A4 paper size is selected, the printer reduces a
larger image to fit the A4 size.
◦The % of normal size option enlarges the printable area of the original paper size (the page
minus the margins) by the percentage indicated, then adds the margins to create the output
paper size.
●In the Mac OS Print dialog: select the Paper Handling panel, then Scale to fit paper size, and
select the paper size to which you want to scale the image. If you want to increase the size of the
image, make sure that the Scale down only box is unchecked.
●
Using the front panel: select the Setup menu icon 
, then Printing preferences > Paper >
Resize.
If you are printing to a single sheet, you must ensure that the image can actually fit onto the sheet,
otherwise the image will be clipped.
Change the treatment of overlapping lines
NOTE:This topic applies only when printing an HP-GL/2 job.
The merge option controls the overlapping lines in an image. There are two settings:
●Off: where the lines cross, only the color of the top line is printed.
●On: where the lines cross, the colors of the two lines merge.
To turn merge on, go to the front panel and select the Setup menu icon 
, then Printing
preferences > HP-GL/2 > Enable merge. You can set the merge option from your software in some
applications. Settings in your software override the front-panel settings.
Print a draft
You can specify fast draft-quality printing in the following ways:
●In the Windows driver dialog: go to the Paper/Quality tab and look at the Print Quality section.
Move the print-quality slider to the extreme left (Speed).
●In the Mac OS Print dialog: go to the Paper Type/Quality panel and select Paper, then move
the print-quality slider to the extreme left (Speed).
●
Using the front panel: select the Setup menu icon 
, then Printing preferences > Print
quality > Select quality level > Fast.

							You can specify even faster draft-quality printing by using Economode, as follows. This is intended
mainly for documents containing only text and line drawings.
●In the Windows driver dialog: go to the Paper/Quality tab and look at the Print Quality section.
Select Custom Options, then set the quality level to Fast and check the Economode box.
●In the Mac OS Print dialog: go to the Paper Type/Quality panel and select Paper, then set the
quality options to Custom, set quality to Fast, and check the Economode box.
●
Using the front panel: select the Setup menu icon 
, then Printing preferences > Print
quality > Enable economode.
NOTE:If the print quality is set from your computer, it overrides the print-quality setting in the front
panel.
High-quality printing
You can specify high-quality printing in the following ways:
●In the Windows driver dialog: go to the Paper/Quality tab and look at the Print Quality section.
Move the print-quality slider to the extreme right (Quality).
●In the Mac OS Print dialog: go to the Paper Type/Quality panel and select Paper, then move
the print-quality slider to the extreme right (Quality).
●
Using the front panel: select the Setup menu icon 
, then Printing preferences > Print
quality > Select quality level > Best.
NOTE:If the print quality is set from your computer, it overrides the print-quality setting in the front
panel.
If you have a high-resolution image
If your image has a resolution greater than the rendering resolution (which you can see in the Custom
Print Quality Options box under Windows), print sharpness may be improved by selecting the Maximum
Detail option. This option is available only if you are printing on glossy paper and you have selected
Best print quality.
●In the driver dialog (Mac OS Print dialog): select Custom instead of Standard print-quality
options, then check the Maximum Detail box.
●
Using the front panel: select the Setup menu icon 
, then Printing preferences > Print
quality > Enable maximum detail.
NOTE:The Maximum Detail option results in slower printing with photo papers, but it does not increase
the amount of ink used.

							Print in gray shades
You can convert all colors in your image to shades of gray in the following ways:
●In your application program: many programs provide this option.
●In the Windows driver dialog: go to the Color tab and look at the Color Options section.
Select Print In Grayscale. You can also select Print in Pure black and white if you want only
black and white, without gray shades.
●In the Mac OS Print dialog: go to the Paper Type/Quality panel and select Color, then select
Print In Grayscale. You can also select Pure Black and White if you want only black and white,
without gray shades.
Print with no margins
Printing with no margins (to the edges of the paper) is known as borderless printing. This can be done
only on rolls of glossy paper.
In order to be sure of leaving no margins, the printer prints slightly past the edges of the paper. Any ink
deposited outside the paper is absorbed by the sponge situated in the platen.
You can request printing with no margins in the following ways:
●In the Windows driver dialog: select the Paper/Quality tab and press the Margins/Layout
button. Then select Borderless.
●In the Mac OS Page Setup dialog: select a paper size name that includes the words “no margins”.
Then, in the Print dialog, select Paper Type/Quality > Layout > Borderless.
When you select Borderless, you must also select one of the following Image Enlargement options:
●Automatically by printer means that the printer automatically enlarges your image slightly
(normally by a few millimeters in each direction) in order to print over the edges of the paper.
●Manually in application means that you must enlarge the image yourself in your application, and
select a custom paper size that is slightly larger than the actual paper size.
NOTE:If the first print job after loading paper is a borderless job, the printer may trim the leading edge
of the paper before printing.
At the end of a borderless print, the printer normally cuts the print slightly inside the image area to ensure
that the print is borderless. It then cuts the paper again so that no residual part of the image is included
in the next print. However, if the job is cancelled, or if there is white space at the bottom of the image,
only a single cut is made.
Reprint last printed job
You can reprint the last job printed from the front panel. Select the Job management menu icon ,
then Reprint last job.
NOTE:You cannot use this method for PCL3 jobs. To reprint old jobs that are PCL3, you may be able
to use your operating systems printer spooler, if you have already set the spooler to save old jobs. This
facility depends on your operating system.

							Use paper economically
You may be able to save some roll paper by using the following options:
●In the Windows driver dialog: select the Features tab and then Remove top/bottom blank
areas and/or Rotate by 90 degrees.
●In the Mac OS Print dialog: select the Paper Type/Quality panel, then Paper, then Remove Top/
Bottom Blank Areas.
Use ink economically
Here are some recommendations for making economical use of ink.
●For draft prints, use plain paper and move the print-quality slider to the left end of the scale
(Speed). For further economy, select custom print quality options, then select Fast and
Economode.
●Clean the printheads only when needed, and clean only those printheads that need cleaning.
Cleaning the printheads can be useful, but it uses a small amount of ink.
●Leave the printer permanently turned on so that it can maintain the printheads in good condition
automatically. This regular printhead maintenance uses a small amount of ink. However, if it is not
done, the printer may need to use much more ink later to restore the health of the printheads.
●Wide prints make more efficient use of ink than narrow prints, because printhead maintenance
uses some ink, and its frequency is related to the number of passes made by the printheads.

							Introduction
HP Designjet T610 printers have 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 RGB (Red-Green-Blue) color model, while most printers use the CMYK (Cyan-Magenta-Yellow-
blacK) color model.
An image can be converted from one color model to another, but in general the conversion is not perfect.
Your printer uses the RGB color model: the same color model that is used by your monitor.
This simplifies but does not completely solve the problem of matching colors. Each device represents
colors a little differently from another device, even if they use the same color model. However, software
can adjust the colors in an image according to the characteristics of the particular device, using a color
profile of the device, in order to achieve correct colors.
A summary of the color management process
To get the accurate and consistent colors that you want, you should follow these steps for each paper
type that you use.
1.Color-calibrate the paper type, for consistent colors. Calibration should be repeated every now and
then (see 
Color calibration on page 56). In addition, you may wish to calibrate immediately before
a particularly important print job for which color consistency is vital.
2.When printing, select the correct color profile for the paper type you are using.
Color calibration
Color calibration enables your printer to produce consistent colors with the particular printheads, inks,
and paper type that you are using, and under your particular environmental conditions. After color
calibration, you can expect to get similar prints from any two different printers situated in different
geographical locations.
Some paper types cannot be calibrated. For all other paper types, calibration should be done in any of
the following circumstances:
●Whenever a printhead is replaced
●Whenever a new paper type is introduced that has not yet been calibrated with the current set of
printheads
●Whenever the environmental conditions (temperature and humidity) change significantly
56 Chapter 7   Color management ENWW
Color management
 
						

							You can check the color calibration status of the currently loaded paper at any time by pressing the
View loaded paper 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 calibrated, and the calibration is up to date.
●DISABLED: this paper cannot be calibrated.
NOTE:Color calibration cannot be performed on plain paper, nor on any kind of transparent
material.
You can also check the color calibration status by using HP Easy Printer Care (Windows) or HP Printer
Utility (Mac OS).
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 Image Quality Maintenance menu icon 
, then Calibrate
color.
The calibration process is fully automatic and can be performed unattended after you have loaded paper
of the type you wish to calibrate—which should be A3 or any larger size.
The process takes about 3–5 minutes and consists of the following steps.
1.A calibration chart is printed, which contains patches of each ink used in your printer.
2.The chart is allowed to dry for a period of time that depends on the paper type, so that the colors
have time to stabilize.
3.The chart is scanned and measured.
4.From the measurements, the printer calculates the necessary correction factors to apply for
consistent color printing on that paper type. It also calculates the maximum amount of each ink
that can be applied to the paper.
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.
ENWW Color management from printer drivers 57
Color management
 
						

							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 profile embedded in
the image and the ICC profile of your printer and paper type.
●Printer-Managed Colors: in this case your application program sends your image to the printer
without any color conversion, and the printer converts the colors to its own color space. Color
management is done using a set of stored color tables; ICC profiles are not used. This method is
somewhat less versatile than the previous methods, but is a little simpler and faster, and can
produce good results with standard HP paper types.
NOTE:There are only two color spaces that the printer can convert to its own color space using
the stored color tables: Adobe RGB and sRGB if you are using Windows, Adobe RGB and
ColorSync if you are using Mac OS.
ColorSync is the Mac OS built-in Color Management System; so, in fact, when selecting ColorSync
it is the built-in color management part of Mac OS that is performing the color management, and
it is done based on the ICC profiles of specified paper type. ColorSync is available with the PCL
driver only.
You are recommended to consult the Knowledge Center at http://www.hp.com/go/knowledge_center/
djt610/ to see how to use the color management options of your particular application.
To choose between Application-Managed Colors and Printer-Managed Colors:
●In the Windows driver dialog: select the Color tab.
●In the Mac OS Print dialog: select the Paper Type/Quality panel, then Color.
●In some applications: you can make this choice in the application.
Printer emulation
If you want to print a particular job and to see approximately the same colors that you would get from
printing the same job on a different HP Designjet printer, you can use the emulation mode provided by
your printer.
NOTE:This option is available only when printing an HP-GL/2 job. It will work correctly only when
printing on plain, coated, or heavyweight coated paper.
●In the Windows HP-GL/2 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: select the Paper Type/Quality panel, then Color > Printer Managed
Colors > Emulated Printer.
Color adjustment options
The aim of color management is to print accurate colors. If you perform color management correctly,
then you should be able to print accurate colors with no need of any manual color adjustments.
However, manual adjustments may be useful in the following situations:
●If your color management is not working correctly for some reason
●If you want colors that are subjectively pleasing rather than accurate
The printer driver provides different adjustment facilities depending on whether you are printing in color
or in grayscale. If you are printing in pure black and white, there are no color adjustment options.

							Printing in color
You can adjust the colors of your print in similar ways under Windows and Mac OS:
●In the Windows driver dialog: select the Color tab, ensure that the Advanced Color
Adjustments box is checked, then press the Settings button beside it.
●In the Mac OS Print dialog: select the Paper Type/Quality panel, then Lightness and Hue.
Under either operating system, you will then be able to make adjustments using a lightness slider and
three color sliders.
●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 Color tab, ensure that the Advanced Color
Adjustments box is checked, then press the Settings button beside it.
●In the Mac OS Print dialog: select the Paper Type/Quality panel, then Gray balance.
Under either operating system, you will then be able to make adjustments using separate controls for
highlights, midtones, and shadows.
ENWW Color management from printer drivers 59

							●The lightness slider simply makes the whole print lighter or darker. This slider is available under
Windows in the same window as the other grayscale controls; it is available under Mac OS 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 to its default setting.
Color management from the front panel
You can color-calibrate the loaded paper type from the front panel by selecting the Image Quality
Maintenance menu icon 
, then Calibrate color. See Color calibration on page 56.
The other color options in the front panel can all be found by selecting the Setup menu icon 
,
then Printing preferences > Color.
NOTE:These front panel settings can all be overridden by the printer driver.
●Color/Grayscale: you can choose to print in color or in shades of gray. Default: Print in color. 
●Select RGB source profile: you can choose from a selection of RGB source profiles recognized
by the printer. Default: sRGB (HP). 
●Emulate printer: you can choose to emulate a different HP Designjet printer. Default: None (no
printer emulation). 
TIP:If you have old HP-GL/2 files made for a different HP Designjet printer, you can send them
to the printer and use the front panel to turn on the appropriate emulation mode.
