Topic 4.2: Classifications of tactile Graphics

This topic introduces you to the categories of tactile graphics according to their production methods.

We classify tactile graphics according to the following production methods:

• Embossed braille
• Micro capsule
• Vacuum form
• Collage

This picture is an example of an Embossed Braille Image.

The computer image will likely require simplification before embossing. After the image has been manipulated and Braille labels and/or text are added, it is sent to the embosser for the hard copy to be printed.

Images can be imported into some Braille translation software and embossed as part of a regular Braille document.

 When embossed graphics lack definition, their tactual quality can be enhanced by adding embellishments such as collage to the page.

The Tiger® braille printers use proprietary software (Tiger Software Suite) and specific Braille fonts (Braille 29) for their embosser output.

The following list provides some important considerations for creating vacuum-formed tactile graphics:

The weight (thickness) of the plastic

The temperature of the heating element

The length of time the vacuum pump runs all contributes to the quality of the copy.

NOTE: Some materials are not suitable for the vacuum-form process because they may melt, dry out, crease, fall off, or give off toxic fumes. This can happen when heated at high temperatures
