Chromix IDEAlink Curve3 Software Upgrade

What's New in Curve3?

Smoothing

Undoubtedly, the behavior of the printing device as well as the measurement device most strongly affects G7 calibration and the output of the Curve. Curve3 implements a new, comprehensive smoothing method based on a multi-dimensional smoothing algorithm that can use all the printed patches if required. The more measured sheets read in, the better the smoothing algorithm works. This algorithm has been proven to work wonders on rough, difficult measurements from flexo printing, digital printing, and other ill-behaved systems. The best part is, you can simply click a check box to enable this wonderful feature.

Special Inks

G7 revolves around near neutral colors typically made up of CMYK inks. Due to the focus on CMYK, the toning of additional channels has been left out. Luckily, Curve3 takes care of this with its new "Special Ink" mode in addition to the existing G7 and TVI modes.

Spectral VPR

After the countless outstanding reviews received by Curve2's Virtual Press Run (VPR), Chromix took it one step further in Curve3. By reading in a full IT8 target (or other profiling target if desired) along with your P2P target, VPR curves the IT8's color values, saving you the extra press run. In Curve2 VPR curves the Lab values to simulate the curved press run. In Curve3 VPR curves the full spectral values. This provides you with the full complement of measurement information with which to build profiles, determine density values, etc.

Improved Error Reporting

Curve3 has been improved to be more diligent with providing errors when you need to know your data is outside the useable range. This removes the bad reversals and other data problems prevalent in Curve.

User Specified Starting Calibration

If your initial press run was made with non-flat curves either accidentally or due to printing necessity, Curve3 can now accommodate. The initial curves used in your RIP can be entered into Curve for curve calculating.

What's New in Curve2?

Ease of G7 Implementation

Over 50 new functions and features have been added to Curve2, enhancing the intuitive interface of IDEAlink Curve to further simplify the G7 calibration process and improve its effectiveness. From basic pre-qualification tools that verify ink and paper colors, to conformance metrics for NPDC and gray balance, Curve2 elevates the whole process of G7 calibration and monitoring.

All aspects of a G7 calibration are contained in a new document format capable of holding a series of related press runs in one single file. Successive press runs are linked to previous runs so that Curve2 can accurately calculate new curves based on previous curves, perform run-to-run checks, and qualify how accurately a particular run or sample meets the G7 definition.

NEW Virtual Press Run Module:

Without VPR, obtaining a press profile from a G7-calibrated press requires at least two press runs; one with null plate curves to calculate the G7 calibration curves, and a second to print the profiling target through the resulting plate curves to profile the press.

VPR normally eliminates the need for the second press run. The G7 curves calculated from the first run are applied mathematically to the profiling target measurements of the first run, producing measurements that appear as if they were produced on a second "virtual" run.
