Is G7 calibration possible in ChromaChecker projects?

Since you're asking about G7 calibration in ChromaChecker, let's clarify how Projects fit into that process.

The relationship between Projects and G7 Calibration

Projects themselves don't directly perform G7 calibration. However, Projects can be configured to collect the necessary measurement data that is then used for G7 calibration within ChromaChecker's other tools, specifically Print Inspector and Curver Inspector.

Here's the workflow:

  1. Project Setup: You create a Project that uses a control strip containing the patches needed for G7 calibration (e.g., CC-84 or P2P).
  2. Data Collection: Operators use ChromaChecker Capture (likely Packaging Inspector or Print Inspector, depending on the press type) to measure the control strip from prints made as part of the Project.
  3. Calibration in Print Inspector: The measurement data collected and stored under the Project is then accessed within Print Inspector. Print Inspector has dedicated tools (G7 Curve Inspector or TVI Curve Inspector) to generate G7 calibration curves from that data.

Key points:

  • The Project provides the framework for consistent data collection related to a specific print job or standard.
  • Print Inspector provides the tools to analyze that data and create G7 calibration curves.

How to get started:

  1. Create a Project: Set up a project that includes a supported control strip (CC-84, P2P, or similar).
  2. Measure the Control Strip: Using either the Print Inspector or Packaging Inspector interface in ChromaChecker Capture, measure the control strip as part of your Project.
  3. Access Data in Print Inspector: Go to Print Inspector in the web interface to find the collected measurements linked to the Project and printing device.
  4. Calibrate: Use the G7 Curve Inspector within Print Inspector to generate calibration curves based on data from your project measurements.

Important Considerations:

  • Control Strip Selection: Ensure the control strip you use in your Project has the patches needed for G7 calibration.
  • Print Inspector: G7 calibration is performed within Print Inspector using the data collected from the project measurements.
  • Calibration Type: ChromaChecker's calibration can be used as a correction to previous calibrations, using production files, eliminating the need for dedicated print runs.

To learn more about G7 calibration specifically, you can also refer to the Print Inspector documentation.

If you are new to ChromaChecker, join one or both of our sample initial projects:

  • "GRACoL Process" Sample Project: This project is recommended for instruments with scanning capabilities and utilizes the ChromaChecker CC-84 three-row control strip. It includes a ChromaChecker-developed G7 calibration engine (Idealliance certified). This seems like a good starting point if you have a compatible instrument and control strip.
  • "P2P G7 Curves" Sample Project: This project demonstrates the creation of G7 curves using production data and an Idealliance-certified engine. It aims to eliminate dedicated print runs and enable continuous monitoring. It requires scanning the ChromaChecker Capture Print Inspector with the selected Project from the list.

Keep in mind that while Projects can collect the necessary data, the actual G7 calibration is performed in Print Inspector using tools like G7 Curve Inspector.

To proceed, I suggest the following:

  1. Join the Sample Projects: If you haven't already, join the "GRACoL Process" or "P2P G7 Curves" sample projects to experience the workflow. You can request an invitation to join sample initial projects on the Start Projects page.
  2. Verify Instrument and Control Strip Compatibility: Ensure that your measuring instrument and control strip are compatible with the chosen sample project. The "GRACoL Process" project is best for instruments with scanning capabilities using the ChromaChecker CC-84 control strip.
  3. Deploy the Project: In Project Inspector, deploy the chosen project to one or more of your printing devices.
  4. Measure and Calibrate: Use ChromaChecker Capture (Print Inspector) to measure the control strip. Then, use the G7 Curve Inspector within Print Inspector to perform the calibration.

Please note:

If you already have previously measured measurement files, you can load them directly into the project.
