Instrument Inspector

Harmonizer — How It Works?

This industry breakthrough technology - (option of Instrument Inspector) enables the ability to normalize the differences between all instruments in your production chain. Select one "Master Instrument" and ChromaChecker will recalculate "on-the-fly" incoming measurement data to match Master Instrument as close as possible. 

All Instruments requiring normalization have to be registered in Instrument Inspector and physical Instrument Inspector targets have to be measured. When setting-up the Harmonizer technology each Instrument has to measure target 10-20 times to build a Baseline, which creates an average definition of how instrument "measures" color differently. 

When baselines are created, the system creates correction profiles for each instrument with relationship to Master Instrument. Stored information will be used for future data recalculation.

Each Instrument, including the Master, requires routine verification to ensure that correction profile is up-to-date. This routine gives additional knowledge about current instrument state – if a device is consistent and precise in its measurements.


Inter-Instrument Agreement. 

There are a lot of vendor declarations on how Instruments are precise and stable. But in real world instruments can be dropped, temperatures vary, optics become dirty (industrial environment is sometimes very polluted, the air in print house may contain a lot of dust) all of which causes instruments to change how they measure color. Real Inter-Instrument Agreement can be far from perfect. Sending Instrument for recertification is expensive, and usually doesn't fix the problem if it is software or application related.

Frequent Instrument verification with Instrument Inspector will document that Instrument is valid and there is no need for sending Instrument for the recertification — checking every week or every month will create records for the audit. ISO 9001 required documentation will be created and at the same time the correction profile is generated.

Typical Inter Instruments comparison shows E-Factor in the range of 1- 2 delta E and much higher in some cases depending on the instrument pair. In most cases Harmonizer can reduce this error by 60% for unlike instruments, and even higher for like instruments.

A typical scenario where this becomes critical is when the ICC profile for the proofer was made with iSis or i1IO, and the proof verification is made with Exact or i1Pro. An excellent ICC profile is 2 CRF ∆E from aim when measured with the different instrument because two different instruments measure same patches differently. Harmonizer can reduce this problem by 50% or more! In the same way measurements from handheld device may be very different from press instrument, and Harmonizer will reduce this delta E stack that contributes to over all error in the process. By reducing this error, the printer will have an easier time manufacturing color to meet the customers expectations which will save time and money due to less waste, and less make ready, and less discussion related to the color product.
