Using the PDF Comparator in LVS-75XX software

Recommended Posts

p by step procedure demonstrating how to use the PDF comparator in the LVS75xx application.


  •  The comparison of the LVS-7510 golden to the Master PDF file happens only at setup.
  • ScanProof compares the .BMP version of the LVS-75XX golden image created from the label during the AutoSetup process to a PDF Master artwork file selected by the user.
  • This comparison happens on only one image; the golden image taken during setup. After the comparison in ScanProof, the LVS golden image is compared to the image of every label printed.


 From the Blemish setup screen of the LVS-75XX software, the Correlate Artwork button launches the ScanProof application.

  • The LVS-7510 application goes dormant while ScanProof is performing the comparison. The ScanProof application produces a comparison report and passes it back to the LVS-7510.
  • When the ScanProof application terminates, the LVS-7510 returns to the Blemish Setup screen.
  •  A report from the ScanProof application is passed to the LVS-7510.

•       If the report is marked Fail, the LVS-7510 software notifies the user of a failed report.

•       If the report is marked Pass, the LVS-7510 allows the user to complete the Blemish setup.
