Tactile Graphics
Tactile graphics are raised visual representations designed to be read through touch by individuals who are blind or visually impaired. They are used to communicate information that would otherwise be presented visually, such as diagrams, maps, charts, and illustrations.
What Are Tactile Graphics?
Tactile graphics translate visual information into physical textures that can be explored through touch. Tactile graphics represent shapes, spatial relationships, and visual structures.
They are commonly used to represent:
- Diagrams and illustrations
- Maps and wayfinding systems
- Graphs and charts
- Educational materials
- Signage and labeling
- And more…
How Are Tactile Graphics Created?
There are several methods used to produce tactile graphics, each suited to different needs.
Swell Paper
Swell paper is one of the most widely used methods for producing tactile graphics. It uses heat-reactive microcapsule paper that expands when printed with black ink and exposed to heat.
- Fast production
- High detail accuracy
- On-demand creation
- Flexible workflow

Braille Embossers / Braille Printers
Embossers/printers create braille dots on paper
- Commonly used for braille
- Suitable for simple graphics
- Limited detail
- Interpreting graphics made of braille dots can be hard
Thermoform Machines / Brailon Duplicators
Thermoforming uses heat and masters/molds to create durable tactile graphics.
- Ideal for high-volume production
- Requires masters/molds (the more creative the better!)
- Less flexible
- Graphics are extremely durable
Why Tactile Graphics Are Important
Tactile graphics make visual information accessible through touch, supporting education, navigation, and independence.
They are especially important in:
- Education (STEM, diagrams, maps)
- Orientation and mobility
- Workplace training
- Public accessibility
Best Practices for Tactile Graphics Design
Effective tactile graphics require thoughtful design.
- Keep designs simple and clear
- Use consistent spacing
- Avoid unnecessary detail
- Maintain clear structure
- Use recognizable symbols
Choosing the Right Method
Different methods serve different needs:
- Swell paper: Fast, detailed, flexible
- Embossing: Best for braille
- Thermoforming: Best for volume and durability
For many applications, swell paper offers the best balance of speed and detail.
Zychem and Tactile Graphics
Zychem has been a leader in tactile graphics production since 1991, manufacturing Swell Touch paper and both Swell Form and Swell Form Pro machines in-house.
This allows consistent performance, reliable output, and high-quality tactile graphics production.
Getting Started with Swell Paper Tactile Graphics
To begin creating tactile graphics using swell paper, you will need:
- Swell paper
- A compatible inkjet or laser printer using black ink
- A swell marker
- A swell paper machine
Conclusion
Tactile graphics are essential tools for making information accessible. With multiple production methods available, they can be adapted to different needs and environments.
Swell paper remains one of the most efficient and flexible solutions for producing tactile graphics on demand.
