In 2024, maintaining flawless print quality is more critical than ever. This is especially so in highly regulated fields like pharmaceuticals which are governed by bodies like the FDA (Food and Drug Administration), where a single printing error can have serious consequences.  For instance, a single misprinted dosage instruction on a medication label could pose a health risk to consumers.

According to a recent study, labeling errors are the most common cause of food allergen recalls, accounting for over 70% of recalls with known root causes. In addition to the potential safety hazards, printing errors can also result in expensive recalls, cause delays in product launches, and damage a company's brand reputation. Document comparison software emerges as a powerful tool in this scenario, streamlining print inspection and significantly reducing the likelihood of errors that can lead to these costly repercussions.

The inner workings of print inspection in 2024

Print inspection methods have undergone a significant transformation in recent years. Today's approach incorporates a multifaceted toolbox, strategically combining the irreplaceable human touch with AI-powered automation to achieve the pinnacle of printed material quality. While automation plays an increasingly prominent role, the role of the trained inspector remains vital in the quality assurance process.

Using legacy inspection processes 

Even in the age of automation, label reviewers remain a vital first line of defense. Their experience allows them to meticulously compare printed outputs against digital artwork, scrutinizing text accuracy, formatting consistency, layout integrity, and even color fidelity across the print run. While effective for catching major discrepancies, manual inspection is inherently time-consuming. The human element also introduces the possibility of errors due to fatigue or overlooking subtle inconsistencies.

Visual inspection tools

Online digital proofing tools have now become a mainstay in the print inspection landscape. These web-based platforms allow for real-time collaboration between designers, inspectors, and clients on the same digital file. Stakeholders can upload the artwork file, and then reviewers can add comments, annotations, and markups directly on the file, highlighting any discrepancies or areas requiring attention. 

This streamlines communication and eliminates the need for physical copies, saving time and resources. Furthermore, digital proofing tools often offer features like version control, which allows reviewers to track changes made to the file over time and revert to previous versions if necessary. This ensures a clear audit trail and facilitates a more efficient review process.

Automating optical inspection

Marking a significant leap forward, Automated Optical Inspection (AOI) systems leverage high-resolution cameras and image processing software, often powered by Artificial Intelligence. These digital workhorses analyze printed materials by comparing them against a pre-defined reference image. AOI excels at identifying deviations in color, registration (alignment of different ink layers), and even physical defects on the printed surface like scratches or smudges. However, AOI systems can struggle with layouts that deviate from the norm and may miss errors related to content, such as a typographical mistake or an incorrect dosage instruction. 

Here's where AI comes in: By incorporating machine learning algorithms, AOI systems can be trained to recognize a wider range of anomalies, including variations in layout or subtle visual inconsistencies. This significantly improves the system's ability to detect potential defects and reduces the workload for human inspectors. In essence, AOI with AI acts as an assistant to manual inspection, freeing inspectors to focus on more complex tasks that require human judgment and critical thinking skills.

Automating workflows with document comparison

This is where the latest advancements come into play. Software like Artwork Flow pushes the boundaries beyond mere visual comparisons. It employs intelligent algorithms to perform a deep dive into the content of the documents, analyzing not just the layout and formatting but also the underlying text, data, and even embedded elements like barcodes and QR codes. Picture a scenario where a medication label is being inspected.

An AOI system might identify a misaligned logo, but it wouldn't be able to detect a typographical error in the dosage instructions or a missing allergen warning. Artwork Flow’s document comparison software, on the other hand, would not only catch the misaligned logo but would also flag the incorrect dosage and missing allergen information with the help of ComplyAI. This could likely prevent a critical error from reaching consumers and leading to a costly recall. Its ability to analyze text content extends to more nuanced discrepancies as well. 

For instance, it can identify a seemingly minor inconsistency like a hyphen added or removed from a product name, which could have legal ramifications or cause confusion for consumers. Furthermore, document comparison software can ensure proper formatting of tables, charts, and graphs, ensuring the accuracy and clarity of data presentation in critical documents like financial reports or engineering specifications.

What is document comparison?

What if you had a meticulous assistant who could analyze two documents line by line, not just for visual differences, but for discrepancies in the copy itself? This is the essence of document comparison software. It goes beyond the capabilities of traditional human inspection or basic visual comparison tools.

At its core, document comparison software utilizes sophisticated algorithms to perform an in-depth analysis of two digital documents. Here's a breakdown of its key functionalities:

• Textual scrutiny: Document comparison software doesn't just look at how the text appears visually; it delves deeper, meticulously comparing the actual content, word for word. This allows it to identify even the most minor discrepancies, such as typos, grammatical errors, missing words, or unintended additions.
• Formatting forensics: Beyond textual content, the software also analyzes formatting aspects like font variations, font size, spacing, margins, and paragraph breaks. This ensures that the layout and presentation of the information remain consistent between the original artwork and the final printed output.
• Data detection and decoding: Modern document comparison tools can also extend their analysis to data-rich documents like financial reports, engineering specifications, or scientific papers. They can identify inconsistencies in tables, charts, and graphs, ensuring the accuracy and clarity of data presentation.
