Curves Sets including any combination of global, red, green, and blue curve
adjustments. After naming the curve set, it can be saved directly to the Spyder3Print
Data > Presets folder, for access from the Spyder3Print Import Curves function.
Absolute Grays Checkbox
This option is most visible in black and white printing. The default choice in
Spyder3Print is Absolute Grays. This setting calculates grays by direct calculation.
Unchecking the Absolute Grays checkbox offers a second option, Paper Relative Grays,
where paper tone is factored into gray calculations. If you paper is very close to a
neutral white, these options will not cause any significant difference in your grays.
Paper Relative Grays may offer more graceful gradation of grays to paper white on
non-brightened papers , while Absolute Grays should offer more literal gray values and
better ramping to white on brightened media.
Editing Profiles Using Curves
Users can edit profiles in Photoshop or compatable applications with a live preview of
their results by using .acv files. Start by opening your sample image in Photoshop, and
softproofing it through your printer profile, using the Custom Proof Setup command.
Now edit this image using a Photoshop .acv curve, at Image > Adjust > Curves.
Global curves adjustments will effect brightness in the selected tones. Red, Green, or
Blue curve adjustments will change color balance in the selected tones. Now name
your curve set and save the .acv file to Spyder3Print’s Data > Presets folder. Select
this curve set in Spyder3Print’s Build Profile Setup window to apply it to your profile.
Building a Profile
Once you have provided a profile name, choosing the Next button will automatically
build your profile using all the current settings, and move you to the application’s final
screen. This process takes only a few seconds. If you attempt to build a profile without
a valid set of measurement data selected, the application may take much longer trying
to work with this incorrect data. In such a case, force quitting the application is the
simplest solution. On the Mac there is a force quit option in the Apple menu. On
Windows press the ctrl, alt, and delete keys and end the Spyder3Print task in the Task
Manager.
