• Cancel: Click Cancel to exit the Q-Curve 5.0
dialog.
• Save As: After you have created a customized file
click Save As to save the file for future use. The
Save As dialog will display. Give your calibration
file a name and click Save.
Note: You should have created a folder on your hard
drive to store your customized calibration files.
It is not wise to save your calibration files in the
PRPC2000 folder. If you upgrade or uninstall
and reinstall you could lose your customized cal-
ibration files.
• Load: When you want to use one of your cus-
tomized files you need to tell PowerRIP 2000.
When you click on Load the Open dialog will dis-
play. Navigate to your calibration folder, highlight
the calibration file you want to use and click
Open.
• All Same: If you select All Same all 4 channels,
Cyan, Magenta, Yellow, and Black will have the
same curve.
• Channel: Using the Channel pull down you can
select one channel, Cyan, Magenta, Yellow, or
Black, and create a calibration file for that channel
only.
The percentages available are 0 through 100%. You can
not define a negative percentage (less then 0) or more than
100%. You can either type the percentage you want in a
specific box on the right of the Q-Curve dialog or you can
drag the curve. If you drag the curve the percentages will
change in the percentage boxes to match the new curve.
After you have created your customized calibration file
click the Load button so that PowerRIP 2000 knows that
is the calibration file you wish to use. Then click OK to
exit the Q-Curve dialog. As long as Use Calibration is
selected in the Folder Scanners Configuration dialog the
calibration file you loaded will be used. Click OK to exit
the Folder Scanner Configuration dialog. Minimize your
PowerRIP 2000. You are now ready to print using your
customized calibration file.
ColorSync Support
ICC profiles are color space definitions. The ICC profile
format is defined by the International Color Consortium
as a cross platform standard. The ability to cross platform
allows you to print from the PC to Macintosh, or the
Macintosh to the PC. ICC compliant applications, such as
Photoshop 5.x, Illustrator 9.x, or Quark,XPress 4.x have
the capacity to output using ICC profiles. PowerRIP
2000 can print from any ICC compliant application.
Installing the ICC Profiles
PowerRIP 2000 comes standard with ICC profiles for all
printers that PowerRIP 2000 supports. They can be found
in the ICC folder on the PowerRIP 2000 CD. These ICC
profiles have been specifically created for the PowerRIP
2000. If you are using Windows 2000 the ICC profiles
must be installed in the WINNT\System32\Color fold-
er. If you are using Windows 98 the ICC profiles must be
installed in Windows\System\Color folder.
1. The files in the ICC’s folder are executable. Put the
PowerRIP 2000 CD in the CD-ROM drive. Open
the ICC folder.
2. Double click on the executable for your printer.
3. The WinZip Self extractor dialog will display. You
have to point the ICC profiles to the Color folder
using the Unzip to folder portion on the dialog.
Click Browse. Navigate to the Color folder. Click
OK.
4. The correct path will display in the WinZip dialog.
Click Unzip. The file will unzip into the Color fold-
er. When finished a dialog will display saying the
Unzip was successful. Close the WinZip dialog.
You now have the ICC profiles for your printer installed
on your system and ready to be used by your applica-
tions. Refer to the ICC ReadMe on the PowerRIP 2000
CD, in the Docs folder, for an in-depth discussion of the
use of ICC profiles in your applications.
Maximum Density for Color
PowerRIP 2000 has been designed to allow users to print
up to 300% maximum color from CMYK files.
Exceeding this number will cause problems with excess
ink. Some desktop drawing applications set black to
400% by default. A black of 400% wastes ink and is too
dense to print well on printers and large commercial off-
set presses. Most magazines’ printing standards, depend-
ing on the publication and stock, only allow maximum
black within a range of 260% to 285%.
