C4 CalibrateTool

CALIBRATE Tool

The Curve4 CALIBRATE Tool will ship in the full release expected near the end of this year. It is not available in the initial Curve4 VERIFY release.

Full details regarding the new features and upgraded functions will be available here before it ships. In the meantime we can mention some features:

Updated Interface
Like the VERIFY Tool, you'll have easy access to prior calibration sessions including subsetting into presses / customers / etc.
Ink Channel Limiting / Balanced Neutral Black
Up to now, Curve has never altered the 100% level of any ink channels. For offset printing, this is the recommended method. But wth inkjet printing, where the gamut tends to be larger and the mass tone effect can cause significant hue shifts as ink density increases, limiting ink channels can be useful. Gray balance works better when the 300% CMY patch is close to neutral. Curve4 will help bring that CMY combination under control, improving gray balance and tonality in the process.
Calibration from a smaller initial target
For some printing systems a target smaller that the venerable P2P is sufficient for G7 calibration. Curve4 will support such targets.
Recalibration from a very small target
When re-calibrating a printing system that has already been successfully G7 calibrated, it's sometimes possible to use a very small target indeed. Curve4 will support Fast Re-Calibration using these targets (when it's appropriate for the printing system and pre-calibrated state)
SCTV (Spot Color Tone Value) support
Curve3 used Percent ΔE to calculate calibration of special ink curves. Since then, the Idealliance Print Properties group has settled on a newer, similar method called Spot Color Tone Value. Curve4 will, of course, fully support this new method.


and other cool things to come...
