VERIFY Tool

Curve4's new Verify Tool calculates G7 conformance according to the most up-to-date IDEAlliance specifications and returns the results in a clear visual format. Whether you're looking for G7 Grayscale, G7 Targeted, or G7 ColorSpace compliance, or simply wanting to verify a Color Proof, the Verify Tool summarizes your results with a clear PASS / FAIL badge.

Each color patch used is graphically displayed in comparison to the reference color. Any patches missing from your target will clearly show up in the display. And if you want SCCA-based (Substrate-Corrected Colorimetric Aims) calculations, Verify can easily handle it, along with subtle G7 differences such as Custom Gray balance.

In short, the Verify Tool gives you confidence in your G7 conformance while remaining easy and flexible to use.

CALIBRATE Tool

 

Updated Interface

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 (only available with Complete license)

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)

Recalibration from a non-P2P target (only available with Complete license)

If you've only run an IT8, ECI2002 or other non-P2P target, Curve4 can generate the information it needs from the supplied patches. It may not have the same level of accuracy as that provided by a P2P target but for many printing systems it'll work just fine.

SCTV (Spot Color Tone Value) support

Curve3 used Percent ?E 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

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.

 

 

BLEND Tool

The BLEND tool is a group of functions to combine, massage and process color measurements so you can build the best ICC profiles possible (among other things).

 

Features include:

White Point Adaptation

Alter the white point of your measurements using SCCA-like calculations.

 

Smoothing & Smart Averaging

The same technology that powers Curve's VPR function can be applied to spectral measurement data. This multi-dimensional smoothing function is a very effective method of improving measurements by minimizing measurement noise and other sources of error that only serve to lower ICC profile quality. BLEND will also allow several methods of averaging multiple measurements together.

 

Apply Curves

Curves created in the CALIBRATE Tool can be applied to measurement sets for Virtual Press Run (VPR) simulation. This function is also available in the CALIBRATE Tool itself.

 

 

Powerful Additional Functions

Measuring (included with all three Curve4 Tools)

Powerful measurement tools are integrated into Curve4 and available within each tool.

I1 Pro, iO, iSis, KM FD-9, Barbieri Spectro LFP and Techkon SpectroDens (Mac only) instruments are supported

 

Virtual Press Run (VPR) (used in Curve4 CALIBRATE Tool, Curve Complete license required)

Save hours of time and thousands of dollars by skipping the verification / profiling run when performing G7 calibration.

The savings are greater than you might think. The first press run can be used to print on a number of different paper types. If VPR eliminates the second runs for each paper, one press run might be all that's needed to G7-calibrate a group of papers. That's a huge savings.

 

OneRun targets (used in Curve4 CALIBRATE Tool)

One Target. OneRun.

OneRun target combines P2P and profiling targets into one, saving press sheet room and aiding G7 calibration of smaller presses

 

The OneRun target, in combination with Curve4's VPR (Virtual Press Run) module, makes it possible to calibrate a press to G7, using multiple papers, and make profiles for the press - all in one run. The beauty here is that you only have to print one target, on one press run to do all this. Press calibration and profiling can't get much easier than this!

 

Maxwell Integration (included with all three Curve4 Tools)

Curve4 now includes direct Maxwell support so existing Maxwell customers can easily access their measurements from the leading cloud-based color monitoring system.

 

Just click the Maxwell logo and you can choose any measurement from Maxwell. One click, and the measurement is automatically downloaded into your Curve4 document and added to the Measurements list in VERIFY, CALIBRATE and BLEND tools.
