What kind of machine are the tactile graphics made on? How would these graphics compare to those made on a Tiger embosser?
The following information was prepared by Karen Poppe.
The O&M Tactile Graphics are produced with our “Green Machine,” or via a thermography method. This type of graphic produces a consistent overall feel, generally with unvarying height and texture (rough). Wherever the ink is applied during the photocopying process, a fine powder is cured to the printed image and results in a combined tactile/print image. The process is conducive to the production of less complicated graphics. Durability varies depending on how well the powder cures to the page, and how well the coverage of ink is applied; there are instances where dots are not consistently formed from cell to cell.
In contrast, the Tiger produces a dot-matrix type of graphic on braille-quality paper. Newer embossers allow combined print and tactile images. Again, the lines will have a “rough” feel, but more comparable to the feel of densely-packed braille dots. However, subtle height differences and line thicknesses are possible depending on how the original graphic is drawn. Because of this, the Tiger is probably better for depicting graphs whereby plotted lines can be more easily distinguished.
