QuickStart — Benchmark Self-Audit (CC-84)

This QuickStart procedure can be performed without an active ChromaChecker account. This capability is provided for demonstration purposes only and can be terminated at any time.
CC Capture is G7® Certified. To use this tool in production requires a subscription.  

 

 

1. Download the PDF and print it on your Printer
(PDF attached on the bottom of this page)

You may print this file using various printer settings and see which setting is most accurate to GRACoL. If so, don't forget to document the settings for each printout. Typical settings are:

  • Calibrated only
  • G7 Curves
  • Color Managed (ICC)

Also, combinations of the above settings are possible. We advise testing all settings that are easily accessible.

2. Download CC Capture, connect supported Instrument

You may select Mac or Windows version. If you find any problem please check the troubleshooting guidelines

 

3. Launch the CC Capture application

At this stage, enter the Organization Name (name used when you registered for your ChromaChecker account if you have not registered yet, enter: SampleDemo, then select the instrument type (in the following example it is X-Rite i1Pro) 

 

 

 

4. Login with the operator's credentials

The application should go to Operator's login page where credentials have to be entered (if you have registered your own ChromaChecker account, use the operator credentials that you defined within Accountability Inspector, if not, then use SampleDemo credentials below).

 

 

SampleDemo account test credentials:
Login: Operator
Password: user

5. Set up application

The user has to select:

  • Printer (left column) - in this example selected device is labeled "Digital Press"
  • Track - Choose one of three substrates:
    • Substrate A will assess to a 5 E-Factor to GRACoL and will generate a G7 Curve in CGATs format
    • Substrate B will assess G7 Gray compliance and will generate a G7 Curve in HP LUT format
    • Substrate C will not pass or fail measurement, just report accuracy, and will generate a G7 in EFI VCC
  • Template - for just printed control strip with the corresponding name on the list is "CC-84_3R"

By selecting a specific printer, the measurement data will populate into that printer allowing for tracking the consistency and accuracy of the printing device.  

 

6. Scan Control Strip

Please watch the attached video (login page) to learn how to operate your instrument, and follow on-screen instructions.

 

7. Read Report

 

 

We see that it passes E-Factor criteria but fails some specific detailed requirements (defined by Tolerance Set which is customizable)

 

8. Create G7 Curves

By clicking the G7 icon (on the RED background) you can create a G7 Calibration correction curve

 In order to get the curve file to download, make sure you choose the download folder icon from bottom left side of screen (third icon from right) to configure where you ant your curve correction file downloaded.

9. Judge data quality - qualify for Curve generation

On the above example, the Blue overprint is out of specification, and curves will not fix this, you may consider building an ICC Profile to fix the blue overprint. Additionally, we can see that the cyan solid has a fairly large delta E variation = 3.14 but conditionally we can accept it and create curves by clicking the "Calculate" button. You may need to perform maintenance to improve within sheet variation of the printer before building a curve or profile.

 

10. Save Calibration curves - install them in your Printing System

Each print track preference can define a different curve file format based on the user's workflow. This ensures that the proper curve will be delivered - the user may specify the default folder where calibration curves are saved. 

 

Apply G7 Calibration, print PDF again, and measure CC-84. Compare before and after!

 

 

NOTES 

Pocket Instruments users

If you are using NIX Spectro 2,  Variable Spectro 1, or i1Pro3 Plus -  print the target to be scaled up by at least 150-200%. These instruments require larger patch sizes to be measured properly.
