Alt Text for Complex STEM Content and Scalable Accessibility

Most journal teams today recognize that accessibility is no longer optional. Expectations around WCAG compliance, funder requirements, and institutional standards have made it part of everyday publishing. Yet alt text for complex STEM content remains a common sticking point.

Scientific figures, charts, equations, and multi-panel visuals carry layered meaning that is not easy to describe. Editors and production teams know the research is strong, but turning that complexity into accessible scientific content can feel inconsistent and uncertain.

This challenge is not about intent or effort. It is about building accessibility into real publishing workflows, without slowing teams down or compromising accuracy.

Why complex STEM content breaks traditional alt text approaches

General guidance on alt text often assumes simple visuals. A photograph, a logo, or a single chart with a clear takeaway. STEM publishing rarely works that way. Scientific figures often combine:

• Multiple data sets in one image
• Visual comparisons that rely on context from the text
• Mathematical notation or symbols that do not translate cleanly into plain language

When teams apply basic alt text rules to these visuals, the result is usually one of two outcomes. Either the description becomes so brief that it loses meaning, or it becomes so detailed that it overwhelms screen reader users.

For journals, this creates uncertainty. Editors worry about misrepresenting findings. Production teams worry about consistency. Authors are unsure how much detail is expected. These concerns are valid, and they explain why alt text for scientific figures remains one of the most challenging parts of academic publishing accessibility.

Where accessibility workflows commonly fall apart

In many publishing operations, accessibility is treated as a final check rather than an integrated process. This is where well-intentioned efforts start to break down.

Common workflow gaps include:

1. Alt text added too late
   When descriptions are written after layout or during final delivery, there is little room for review or correction.
2. Unclear ownership
   Authors, editors, and vendors may all assume someone else is responsible for writing or validating alt text.
3. Limited subject context
   Without enough familiarity with the research, descriptions risk missing what actually matters in the figure.
4. Inconsistent quality control
   Even within the same journal, alt text quality can vary widely from article to article.

These gaps are not caused by lack of care. They reflect the reality of tight schedules, high volumes, and complex content. Addressing them requires rethinking accessibility workflows in publishing, not adding more pressure at the end of production.

What scalable accessibility actually means for STEM publishing

Scalable accessibility is often misunderstood as speed or automation alone. For STEM journals, scalability is really about consistency and confidence over time A scalable approach to alt text for complex STEM content allows teams to:

• Maintain scientific accuracy across issues and volumes
• Apply the same standards regardless of who is working on the content
• Reduce rework caused by late-stage corrections
• Support compliance without relying on individual effort alone

In practical terms, scalable accessibility means treating alt text as part of publishing operations, not a one-off task. It means creating structures that support editors, authors, and production teams instead of leaving them to figure it out independently.

A smarter workflow for alt text in complex STEM content

For many journals, the hardest part of alt text is not knowing that it is required, but figuring out how to do it well for complex STEM content, at scale, and within existing production timelines. This is where Nova Techset’s accessibility solutions are designed to fit naturally into publishing operations.

Nova Techset approaches alt text as a content and workflow challenge, not a last-minute compliance task. Our teams work with scientific figures, charts, equations, and data visualizations every day, which means descriptions are developed with an understanding of both the subject matter and the expectations of academic publishing.

Key aspects of our approach include:

• Context-aware descriptions
  Alt text is created with full awareness of the manuscript context, ensuring that descriptions reflect what the figure is meant to convey, not just what it looks like. This helps preserve scientific meaning while supporting screen reader accessibility.
• Workflow-aligned processes
  Alt text creation is integrated into established production workflows, reducing rework and avoiding delays at later stages. Clear checkpoints help maintain consistency across articles and issues.
• Scalability without loss of quality
  Whether a journal handles a small number of submissions or high volumes of complex STEM content, Nova Techset’s processes are designed to scale while maintaining editorial quality and compliance standards.
• Support for editorial confidence
  By combining subject familiarity with accessibility best practices, Nova Techset helps journals meet WCAG requirements without oversimplifying content or placing additional burden on editors and authors.

By embedding alt text for complex STEM content into a structured, reliable process, Nova Techset helps publishers move toward scalable accessibility that supports accuracy, consistency, and long-term sustainability.

For journals managing high volumes of STEM content, revisiting how alt text fits into existing workflows can be a practical and meaningful step forward. Accessibility does not have to feel like an added burden. With the right approach, it becomes part of doing good publishing work, consistently and responsibly.
