In a manual job of designing an Artwork and visually inspecting the incoming Printed material, human error is always possible and not easy to detect. Thanks to the Pixel Proof Workflow solution the digital inspection system, recognizing a small divergence between versions of Artwork and between its approved reference and the physical reference sample is simply a matter of a moment.

A few well-defined and easy-to-understand steps, each of which can be activated only if you have completed the previous step, will guide you through the delicate task of checking for every tiny divergence in your analysis, Everything will be tracked by the Audit trail, both System and Project and documented in the final report. Your project will be saved in a dedicated and secure data base, viewable at any time, with the peace of mind and certainty of using a widely certified and validated GMP5, FDA 21 part 11, ISO 9001/2015, Annex 11 and Data Integrity system.

The Pharmaceutical Industry is our main sector of reference so much so that we are counted among the first places in the world ranking for the number of off-line installations of Packaging Inspection and Control systems in this sector, both in Italy and in the rest of the World.

Not surprisingly, the first version of Pixel Proof was born with the valuable support of the expertise provided by BAYER Headquarters in Leverkusen, where the collaboration continues to this day.

The many features present in Pixel Proof WorkFlow, such as access to three user levels, the triple-check function with electronic signatures of the operator, reviewer, and approver, as well as the continuous functional evolutions constantly released, make our inspection system a model to be emulated.


Automatically inspects graphics files with precision going down to the single pixel, hence the name Pixel Proof. A digital file overlay, it detects any deviations between version changes ensuring that there are no errors.

It compares different file formats:

Detects differences between different file types created during the graphic creation process.

Pixel Proof WorkFlow checks all deviations found on materials received after the printing stage.

Incoming materials received, usually taken at random by batch number, are thus inspected for congruity with the printing plates.

Ink stains, smudges, printing defects, anything that diverges from the approved master file is highlighted to the operator performing the inspection, only in this way can the divergence be accepted as a deviating error or not.

Pixel Proof WorkFlow automatically checks for 1D, 2D, Datamatrix QR Code barcodes.

It decodes the content and returns the print quality of them through a laser gun reading simulation on 10 horizontal levels. The reference ISOs are 15415 for Datamatrix and ISO 15416 for Barcodes.

Thanks to the Konika Minolta Spectrophotometer we can check the Delta Color of our materials and include its values in the final report of the analysis.

With xRite’s Exact Spectrophotometer, in addition to the Delta value we can check and add the color pantone number to the report.

Braille dot distances are measured and verified by two dedicated scanners.

The basis for comparison of this methodology is encapsulated in the “Marburg Medium” Braille specifications. The quality and heights of the elevations are precisely verified. The value for each individual Braille point will be shown on the screen and included within the End of Inspection Report.

Complies with European pharmaceutical legislation (Directive 2001/83/EG-Humankodex) and the German Drugs Act (§ 10 paragraph 1b AMG), as well as DIN EN 15823.

The Version created for the Quality Control Manager. It simplifies the work of viewing projects and approving them. Thanks to this version, it is possible to approve or reject analyses from any location without having to log in on the project analysis system. Also from the same it is possible to a management of Audittrails, with search and approval functions.

The must-have Version for verifying Press Plates and Files to be sent to press. The PRE PRESS Version is a file-to-file control system that secures pre-press processes ensuring the release of a file that is ready for printing but free of errors. The main function is to detect the presence of any discrepancies, if any, between the approved reference and subsequent versions to it, ensuring that no errors or unintentional changes are present in the pre-press file or in the Digital Print Sheets. This version also includes the VIEWER version.

The Dedicated Laboratory Version for Quality Control. PIXEL PROOF WORKFLOW PRINT Version is a powerful inspection system to verify the quality of all types of printed samples by comparing them with an approved reference. In this way companies are able to detect defects generated by printing that if missed can create both economic damage with product recalls and image damage to their brand.

Pixel Proof WorkFlow PRINT Version with its powerful analysis engine makes use of an easy and intuitive graphical interface, guiding the operator through its analysis path without neglecting any detail. For scanning physical samples it uses high resolution quality scanners, both flat and rotary whose certified range can be seen on this site. This version also includes the PRE PRESS version.

The Version for complete total control of Braille Dot Heights and Color Pantone. PIXEL PROOF WORKFLOW FULL Version contains all previous versions and in addition provides interfaces with the range of Spectrophotometers and Scanners for measuring Braille dot heights. Increased Quality Control and a decrease in time and money are a certainty. This version also includes the PRINT version.

All versions of Pixel Proof WorkFlow except VIEWER monitor and analyze:

  • Electronic Signature
  • Multiple project management
  • Audittrail, user and system management
  • User management on three levels of access
  • Single user license or client-server installation
  • Barcode management, print quality, decoding
  • QR code management, print quality, decoding
  • Datamatrix management, print quality, decoding
  • Data Base management, archived and inspectable projects
  • Braille management, text translation (height measurement with WideTek Scanner)”


  • Pixel Proof WORKFLOW is a guided inspection and verification process based on a standard WorkFlow engine (inspection Workflows can be created / configured according to customer procedure).
  • The system guides the user step by step through the entire process, eliminating the risk of skipping a step. The authorized access function to the system, structured on 3 levels, ensures proper use of the system.
  • Traceability and Compliance: captures, stores and classifies, grafies defects, layouts and creates individual reports. All digital reports are firmed electronically and can be used to detect defects and optimize the production.


  • New technology applied significantly increases performance through multiprocessing and multicomputing.
  • The new and modern user interface, guides the operator through the inspection flow, avoiding routine errors, ensuring a more efficient validation of the quality control process.
