|Similar to the FHWA Standard Alphabets for
Traffic Control Devices, there are six weights, from a thin stroke,
condensed character (1W) to a heavy weight, full-width character (6W).
In addition, each of the six weights of ClearviewHwy are available
in a positive contrast version (white type) designated as â€śWâ€ť, and negative
contrast version (black type) designated as â€śBâ€ť, and have been tailored
by optimizing the stoke widths for the viewing application.
The primary advantage is realized when negative contrast signs (regulatory,
warning, and construction zone, etc.) are lettered with ClearviewHwy.
The viewing distance increases because underglow is minimized. In other
words, the bold appearance of the letter stroke has not been reduced
when viewed at night because of high brightness background. The same
effect improves readability under daylight conditions.
