ChromaChecker™ Cloud

Concept

Simple process – sophisticated color cloud-based solution – 4 easy steps: 

  1. Place control strips next to your normal production work. If possible use more location on single sheet! 
  2. Print normally.
  3. Measure the control strips (supported file formats: CGATs, CXF, SVF, XML)
  4. Upload into your ChromaChecker™ Print Inspector or Curve Inspector and get back a report  or iterate G7 or TVI compensation curves in seconds! To use curves system will require to input curves used for the current production!

 

ChromaChecker™ uses three levels of information

You decide how deep to go to analyze your printing system:

1.E-factor

For general color judgment, we are using E-Factor™ – easy to understand parameter that describes if your output device is meeting your color expectations.

2. Easy Mode:

Simple graphs for various aspects of evaluation with pass/fail examinations.
Easy mode shows progress on timeline and gives comprehensive system picture.

3, Expert Mode:

Reporting all color details by various numerics, plots, graphs, and tables. You may even not know that you have hidden problem that can be easily fixed. Based on your goals, ChromaChecker will help you pinpoint the weakest link in your color chain and help you determine what needs to be done to fix the problem.

  

Compare Feature

 

 

Variation 

Once uploaded data can be analysed by two different modules. Variation Inspector evaluates patches with the same color builds, for example, 100% cyan patches to analyse differences – variations.
Using a test form with numerous repetitive patches is very useful when assessing variation, otherwise, single measurements have to be grouped first within ChromaChecker.  Variation tool will analyse duplicate patch builds and compare the difference. Additionally, a baseline can be assigned to any measurement and the variation to every other measurement will be calculated and graphed.
This is how Variation Inspector can be used to compare the precision of device to itself.
Depending on the organisation of the data, this can be used to analyse intra-page, inter-page, inter-job variations. 
This variation is represented by an amber colored line graph.


Print Inspector uses the same measurement data as Variation Inspector but calculates
the deviation (difference) to targeted Reference Printing Aim defined for the given track which determines the accuracy.
This deviation between measured data and the "referenced data" is displayed by a blue line graph.

 

Track – Print Conditions

Tracks are built to represent different Print Conditions. A print condition defines one output device printed
on one substrate, with one specific ink/toner, using one specific output
setting (resolution, screening technology and ruling). If any of these variables change, you should make an additional track to define the different Print Condition. 
The quality of color reproduction, as well as realistic expectation, may vary between different Print Conditions.
For instance, a print condition defined using a  premium coated stock will perform better quality
than the same device printing on low-cost uncoated paper.
So you have the ability to define a different (goal) E-Factor™ for each Print Condition.

  

Various variables – Various Inspectors

There are many variables that influence Process Control. 
ChromaChecker™ has built Inspectors and Tools to assess and track all variables in process control.
Variables that need to be tracked over time are managed by Inspectors: Print, Substrate, Instrument, Lighting and others.
