C4 CalibrateTool


(available with the Calibrate or Complete license levels)
Updated Interface
Calibration Run
Like the VERIFY Tool, you have easy access to prior calibration sessions including subsetting into presses / customers / etc.
Calibration from a smaller initial target
For some printing systems a target smaller that the venerable P2P is sufficient for G7 calibration. Curve4 supports "miniP2P" and "microP2P" targets with as few as 96 patches.
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 supports 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, of course, fully supports this new method.
Ink Channel Limiting / Balanced Neutral Black
Ink Restriction Function
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 helps bring that CMY combination under control, improving gray balance and tonality in the process.
