Color Inspection Overview 

Color Inspection Mode measures the color-space information of selected points on a master or sample or compares the color-space information between corresponding points on the two files. Points that fall outside of a configurable ΔE (Delta-E 2000) tolerance level are detected as differences that require more attention.

NOTE: The Color Inspection Mode icon is only accessible if the module has been purchased.

Step-by-Step

This section describes the steps to follow when running a color inspection.

1. Load Electronic Files (Skip to No. 2 to Load Scanned Files)

  • Click File Menu > Load Master or click in the Master panel to launch the load-file window. - You can also load a file by using “drag and drop.”
  • Select the Master file from the load-file window and click Open.
  • If the Master is a BMP, PNG, TIF, TIFF, JPG, or LEN file, the image loads in the Master panel.
  • If the Master is a PDF or AI file:
  • Prepare the Master image, if required, using integrated PDF Viewer tools to hide layers and/ or separations, use shapes as regions for repeat detection, etc. 
  • Click File Menu > Load Sample or click in the Sample panel to start repeating the process to load the Sample file.

2. Load Scanned Files (Skip Over if Electronic Files Loaded)

  • Click Load from Scanner > Select Source.
  • Select the applicable scanner from the Scanner Selection window and click Select. 
  • Click Load from Scanner  > Scan Master to scan the Master document. Once scanned, the image loads in the Master panel.
  • Click Load from Scanner > Scan Sample to scan the Sample document. Once scanned, the image loads in the Sample panel.


3. Ensure the Color Inspection Mode Icon is Selected 


4. Select an Action 

To compare points selected on a single master page to the same points on a single sample page or press sheet:

  • Set Action > Single Page

NOTE: When conducting a single-page color inspection comparing a master to a sample with repeats, the shape must be selected using the tools on the toolbars/ PDF Viewer. 

To compare the same points selected on individual full pages/press sheets without looking for repeats to speed up the inspection process:

  • Set Action > One to One.

To compare individual points selected on the Master with individual points selected on the Sample:

  • Set Action > Point to Point.

NOTE: Multi-page files are not supported in Color Inspection Mode.

5. Select Profile (Skip Over if None Exist or Are Needed)

  • Click the Profile drop-down menu to access the list of available profiles.

None is the default profile. Any user can easily create profiles, which consist of collections of points on a master (and sample, in the case of Point to Point inspections) to compare prior to running a color inspection.


6. Select Colors To Measure (Skip to No.6 to Select Colors to Inspect) 

  • Click on the Color Picker icon to launch the Color Inspector window.
  • Select the applicable Pantone book from the drop-down list of the same name. NOTE: To search the selected Pantone book for reference purposes, enter in a value in the Search for a Pantone prompt directly below the Pantone Book drop-down list. The closest Pantone values display in the field directly below.
  • Select the sample size (1x1 pixel, 2x2, 5x5) using the drop-down list of the same name.
  • When moving the cursor over the Master, click on a color to display its LAB, CMYK, and RGB values (along with the closest Pantone colors, which display under the Closest Pantone Value heading).- Alternatively, click on the Add points icon and then on points on the Master, each of which get listed under the Color Points heading, which appears.
    NOTE:
    In the case of a PDF file, the Color Picker automatically detects Pantone colors specified in the separations. Otherwise the closest Pantone matches will display. In the event no Pantone match to a selected point is found, click on one of the closest matches (or manually search for a Pantone and then click on it) to substitute it in under the Color Points heading.- To remove a specific point under the Color Points heading, click the “X” that appears to its far right, beside the selected ΔE level and sample size.- Click on the Quick Report  icon to launch the Report Options window and start the process of generating a report that includes all the LAB, CMYK, RGB, and Pantone information, bypassing the inspection (comparison) process. 

7.  Select Colors to Inspect (Single Page, One to One, or Point to Point) 

  • Click on the Color Picker icon to launch the Color Inspector window.
  • Select the applicable Pantone book from the drop-down list of the same name. NOTE: To search the selected Pantone book for reference purposes, enter in a value in the prompt directly below the Pantone Book drop-down list. The closest Pantone values display in the field of the same name directly below.
  • Select the sample size (1x1 pixel, 2x2, 5x5) using the drop-down list of the same name.
  • Enter the desired ΔE tolerance in the box of the same name.

A.Single Page or One to One

  • Click on the Add points  icon and then on different points on the Master to inspect and see if the corresponding points on the Sample image(s) respect the pre-configured ΔE tolerance. The selected points get listed under the Color Points heading that appears, while the individual LAB, CMYK, RGB, and Pantone values display above.- In the case of a PDF file, the Color Picker automatically detects Pantone colors specified in the separations. Otherwise the closest Pantone matches will display. In the event no Pantone match to a selected point is found, click on one of the closest matches (or manually search for a Pantone and then click on it) to substitute it in under the Color Points heading.- To remove a specific point from under the Color Points heading, click the “X” that appears to its far right, beside the selected ΔE level and sample size.

B. Point to Point

  • Click on the Add points icon and then on different points on the Master and Sample to compare to one another. The points can be added in any sequence, either one in the Master and then one in the Sample (one at a time) or all in the Master followed by all in the Sample, as long as the total numbers match. The selected points get listed under the Color Points heading that appears, while the individual LAB, CMYK, RGB and Pantone values display above.
  • In the case of a PDF file, the Color Picker automatically detects Pantone colors specified in the separations. Otherwise the closest Pantone matches will display. In the event no Pantone match to a selected point is found, click on one of the closest matches (or manually search for a Pantone and then click on it) to substitute it in under the Color Points heading.
  • To remove a specific point from under the Color Points heading, click the “X” that appears to its far right, beside the selected ΔE level and sample size.

8. Create a Profile (Optional) 

  • Select Manage from the Profile drop-down list. The Color Profiles window displays.
  • Click Add. A prompt appears, requesting a name.
  • Enter the name of the profile and click OK.
