H-100 Harmonizer Printable Target.

ChromaChecker™ H-100 is a state of art technology solution dedicated to high precision color processing.

Why we need H-100

This target is designed to print in conditions identical to actual production - that is, the use of the same substrate, with printing the same printing technology and using the same processing method. This solution means that the analyzing system will know the real characteristics of the conditions that the harmonized measuring instruments will later simulate. It is a fact that any that two instruments used for measurements on different substrates will show different mutual deviations. The edge loss effect is a phenomenon that explains such different behavior of measuring instruments. In other words, two instruments can measure prints on coated paper very differently and the resultant measurements can be considerable. Unique substrates like foil or polypropylene/plastics, for example, can create an even larger influence on differences.

 

How it is designed

H100 owes its name to 100 measuring Harmonization patches. In order to maximize the efficiency of the operation, the majority of the patches are normal patches: substrate, CMYK solids, and tints plus G7 grays.

However, for maximum optimization, these patches are supplemented with additional Lab patches. Because of this, the target will dynamically react to various printing conditions. Ideally, your workflow should support and Lab process.

Once printed, it can be used only for the harmonization of the selected substrate and print technology - and as such can be assigned to any Print Inspector track.

Finally, the H-100 depending on substrate and printing technology will cover most of the entire spectrum that is of practical use for color reporduction.

Procedure

This procedure describes how to use Instrument 1 to match Master Instrument 

  1. Print H-100 pdf — this file has both CMYK and Lab patches. If your RIP has a problem with Lab, you may want to convert this file into CMYK using your Output Device ICC Profile. 
  2. Register Master and Instruments 1 in Instrument Inspector
  3. Set Master Instrument as a Master
  4. Measure H-100 Target 10+ times with Master Instrument - upload data and create baseline - be sure to use Measurement condition that is in regular production use - e.g. M1  
  5. Measure H-100 Target 10+ times with Instrument 1- upload data and create baseline
  6. Go to the relevant Print Inspector Track that uses Instrument 1 which you want to harmonize to Master instrument. Click on configuration icon and select Instrument 1 on the list. Select the baseline that describes Instrument 1 when printed on a selected substrate.
  7. Turn Harmonizer ON

From now all data uploaded to the system will be harmonized from Instrument 1 to simulate the Master Instrument.

If you want to check how much deviation harmonization will remove from your process, go to Instrument Inspector and click on the Harmonizer tab. You will see the amount deviation removed from the process, providing more latitude for actual manufacturing deviations. For more detail go to Baseline Tab and compare baselines between Master and Instruments 1.

 

H-100 Variants

Depending on desired instruments to harmonize, various H-100 variants may be applied. 

 1. Standard versions / various patch sizes 


The above Targets can be measured using:

  • Handheld instruments like X-Rite i1Pro, eXact, Techkon Spectrodens, Konica-Minolta FD-5, FD-7 and others
  • XY Instruments: X-Rite i1iO, Barbieri LFP, Konica-Minolta FD-9 and others
  • Measured in spot mode with any benchtop, handheld, colorimeter (Target may be scaled to any size).

2. X-Rite ISis dedicated version

The specific requirements (side diamonds) defined by the iSis instrument resulted in designing an ISis version. The geometric layout has been modified by adding two white columns at the beginning and end so that this target can by easily measured by the iSis, but it can als be measured by other instruments. Additional white areas on both sides of the color patches allow for easy scanning of rows with most other instruments.
Additional white patches are automatically ignored within Instrument Inspector.

 

3. Barbieri Instrument dedicated version

ChromaChecker has also created a Barbieri supported version. This target has an additional row of white patches that provides buffer room for the main colored patches which facilitates the ability to measure with  other instrument from other manufacturers.

 

4. Single row version

Some press side measurement devices can only measure a single row of patches, so ChromaChecker has built the target with 100 patches in one row. In order to provide a sister target that other scanning measurement devices can measure, a second parallel set of patches was designed to allow scanning devices to measure in five separate rows. When this Target is printed on an offset press it is important that the single-row and segment versions are located exactly in the same ink zones, possibly close to each other - to reduce variations to a minimum. If a non scanning measurement device is going to be harmonized with the press side measurement device, only the single continuous row is required.  

 

5. Custom Versions

The user can freely transform the patch layout by changing the size of the patches, the number of columns, rows, adding additional graphic elements to control the devices when the need arises. It is important not to change the patch definition nor the 100 standard fields - so that in the Harmonized measurement file all the fields are defined in exactly the same manner as the original definitions. Variants with additional white fields (versions 110 or 132 patches) can also be used. The number and list of patches cannot change but the order is optional. You can use the Control Strip tool in the InstrumentDriver tab to edit the number of rows and columns - the scramble option will help you keep the contrasts necessary so that you do not need to use the patch separators.
