To Preflight or to Normalise? The Ongoing Quest for Print Perfection

Written by Tim D'Elia | Feb 19, 2025 9:32:27 AM

"To preflight or to normalise, that is the question." It's a query that sparks lively debate in the world of print production. Both preflighting and normalisation are crucial steps in preparing files for print, but they serve different purposes. So, why bother with preflight when you can just normalise? And how might artificial intelligence (AI) change this dynamic in the future? Let's dive in!

What is Preflighting?

Preflighting is like a thorough health check-up for your print files. It's a proactive review process that identifies potential problems before they cause costly errors on press. Think of it as a meticulous detective, scrutinizing every detail to ensure a flawless final product.

A typical preflight check might look for:

  • Low-resolution images: Ensuring images have enough detail for crisp printing.
  • Incorrect color spaces: Verifying that colors are defined correctly for the intended output.
  • Missing fonts: Making sure all necessary fonts are embedded or available.
  • Transparency issues: Identifying potential problems with how transparent elements interact.
  • Overprint settings: Checking if colors are set to overprint correctly.
  • Bleed and trim issues: Ensuring that elements extend properly to the edges for clean cutting.

Traditionally, preflighting has been essential to avoid misprints, delays, and wasted materials. It's the ounce of prevention that's worth a pound of cure.

What is Normalisation?

Normalisation, on the other hand, is like a master organizer for your print files. It's an automated process that transforms files into a consistent, standardized format. Think of it as streamlining your files for maximum efficiency and compatibility.

Normalisation typically involves:

  • Converting file formats: Ensuring all files are in a predictable format (often PDF).
  • Simplifying file structure: Removing unnecessary data and flattening layers.
  • Standardizing color spaces: Converting colors to a consistent profile.
  • Embedding fonts: Ensuring all fonts are included within the file.

The benefits of normalisation are clear: it streamlines the workflow, reduces file size, and ensures compatibility with various printing systems. However, normalisation doesn't catch every potential issue. It's more about creating a consistent foundation than about finding every hidden flaw.

The Limitations of Normalisation: Where Humans Still Shine

While normalisation is a powerful tool, it has its limitations. Certain aspects of print quality require the nuanced judgment that only a human (or, perhaps, a very advanced AI) can provide.

  • Design Integrity: An automated system can't understand the intent behind design choices. For example, a slightly off-center element might be a deliberate artistic decision, not an error. A human preflight operator can make that distinction.
  • Color Management: Converting colors to a standard space is easy. But ensuring accurate and pleasing color reproduction across different devices and materials requires expert knowledge and a keen eye. Consider a brand's signature color – a human can ensure it's perfectly matched, while an automated system might miss subtle nuances.
  • Image Quality: Normalisation might check resolution, but it can't assess the overall aesthetic quality of an image. Is it sharp enough? Is the composition effective? Is it truly print-ready? These are questions that often require human judgment.
  • Font and Text Issues: While normalisation can embed fonts, it might not catch subtle typographic errors like awkward kerning or inconsistent spacing. These details can impact readability and overall design quality.

The Current Workflow: A Hybrid Approach

So, where does this leave us? For the foreseeable future, the most effective pre-press workflow is a hybrid one, combining the strengths of both preflight and normalisation. Checks are performed, and what can be fixed automatically is fixed. The remaining issues are flagged for human review. This approach leverages the speed and efficiency of automation while retaining the critical eye of human expertise. It is like a smart car, it can do lots of things, but there is still a driver.

However, resource constraints often force print providers into a difficult choice at the initial job setup. They might opt to prioritize preflighting to catch critical errors early, but this means the initially approved file isn't the final, print-ready version. They then have to normalize the file later, potentially requiring a second round of approvals – or worse, they might skip the second approval and risk printing a file where errors were introduced during the normalization process.

The Future is Now: AI and the Evolution of Pre-press

But what about the future? Will AI eventually eliminate the need for human preflight operators? The answer is: it's complicated.

AI and Machine Learning (ML) are rapidly advancing. They can already identify many technical issues and even make some automatic corrections. However, they still struggle with the nuances of design intent, color subtlety, and complex layout choices.

However, with AI becoming multi-modal – able to understand images, text, and context – the game is changing. Imagine an AI trained on 40 years of preflight data, correction history, and countless design examples. Such a system could potentially predict and correct issues with incredible accuracy, even anticipating design intent.

The likely future is a shift from manually actioning detailed reports to verifying the results of automated corrections. Humans will become supervisors, ensuring that the AI's decisions align with creative vision and quality standards.

Conclusion: The Ongoing Quest for Print Perfection

So, to preflight or to normalise? The answer, for now, is both. While normalisation streamlines the process, preflight remains essential for catching those subtle, context-dependent issues that automation can miss. The ability to do both, efficiently and at scale, is a key advantage that DALIM offers.

As AI and ML continue to evolve, we can expect more and more of the preflight process to be automated. But even in a highly automated future, human oversight will likely remain crucial. It's about finding the right balance – leveraging the power of technology while preserving the art of print. The quest for print perfection is ongoing, and we're excited to be a part of it. The journey is as much about developing trust in these tools as it is about perfecting their capabilities.
