Readability and Legibility
When
I worked in advertising, 40 years ago, I was taught that a serif type, such as
Times Roman, was more readable than a sans serif type because the first words
that we read in elementary school primers are in that family of typeface. The morning newspaper is also set in a serif
font. We are more familiar with this font, and more comfortable when reading
it. Readability, however, isn’t the same
thing as legibility. Times Roman may be more pleasing to our eyes, but that
doesn’t make it more legible.
So
what do we mean by legibility? The
legibility of the typeface is that you use is also important. Sans serif fonts
generally can be read more easily at a distance than fonts with serifs. Serifs
are those small embellishing strokes that finish off the main strokes of a
letter. That doesn’t mean that you should always use sans serif copy. On the
contrary, most designers will argue that typefaces with serifs are more likely
to be read, because they are more pleasing to the eye. And they’re right!
Bigger is Better.
As
with other things in life, size matters. Especially when your sign is viewed at
a considerable distance. The distance, at which a sign is viewed, determines
the character height of the copy that you should use. One standard is that
one-inch copy can be read at a distance of 50 feet. I don’t know who dreamed up
that rule of thumb, but their eyesight must be that of an eagle. The rule that
I was taught was that for every inch of character height you get twenty-five
feet of readability. I think that you’re safer with that rule!
Viewing
distance is just one consideration. For on-premise signage you also need to
consider the speed at which traffic is moving past the location.
In
addition to making your copy bigger, also use a typeface with a bolder stroke.
Outlining and drop shadow can also improve readability.
Contrast Improves Readability.
Metallic
vinyls, such as smooth gold and silver, gold leaf, and silver and gold large
engine turn, are popular but not always readable. Using a heavy black drop shadow can create
just the right contrast to improve readability. Although black is frequently
used for drop shadows, it isn’t the only color that you should consider. For
example, if you are using gold lettering on a bright red background, try using
a dark red for the shadow. The dark red
will soften the transition from the gold in the foreground to the red background.
Contrasting
colors usually aid readability. Some of the most readable color combinations
include:
- Black on yellow
- Black on white
- Yellow on black
- White on black
- Blue on white
While
using contrasting colors can improve readability, contrast in line value,
typeface and shape can attraction the viewer’s attention and differentiate your
signage from that of your competitors. Using script with big block lettering
was a frequently-used and effective technique of the paint and brush
generation. While variations in
typefaces can be interesting and attract attention, using too many different
fonts is distracting. Usually two different typefaces are enough.

Vinyl Application Videos
Squeegee Technique. Nothing is more basic in vinyl application than the squeegee. But some squeegees work better than others. And there are right ways and wrong ways to use this simple tool. This video clip reviews squeegee selection, squeegee care and squeegee technique. Click to Link
Wet Applications. Dry applications are typically recommended for most vinyl applications. For those exceptions to the rule, this instructional video explains the right way to perform a wet application. Click to Link
Application of Window Graphics. Installing vinyl graphics on glass can be challenging, because the adhesive aggressively grabs onto this high energy surface. Repositioning graphics on window is generally difficult, if not impossible. This instructional video explains how to dry apply window graphics right the first time. It also describes the necessary steps required for surface preparation. Click to Link
Transferring Frosted Window Graphics Films. Because frosted window films are highly textured, transferring cut vinyl graphics can be problematic. This video provides direction in selection of the right application tape and how to apply these films quickly, easily and without problems. Click to Link
3-Step Surface Prep. This instructional video describes how to properly clean the surface of a vehicle before applying pressure sensitive vinyl graphics to a trailer or doing a full wrap of a car or van. This three step surface prep involves detergent washing, solvent cleaning and a final wipe down with IPA. Click to Link
Vinyl Application Over Rivets. Applying vinyl graphics on vehicle surfaces with rivets is challenging for most sign makers. Vinyl failures to these surfaces are all too common. This video demonstrates some tips and procedures, used by professional decal installers, which will make these demanding applications easier and more trouble-free. Click to Link
Vinyl Application to Corrugations. Learn how to apply vinyl graphics to corrugations in a relaxed state. Forcing films into the valleys of corrugations puts too much mechanical stress on the film. Sooner or later, the vinyl will lift or tent in valleys. Click to Link
Applying Air Egress Vinyls. Vinyl films with air egress release liners have almost eliminated bubbles and wrinkles from applied graphics. Air egress release liners with their highly textured surface structure are problematic. Not much will stick to these liners other than the vinyl film. At RTape our best premask solution for air egress liners is a special Conform® tape called 4761RLA. Click to Link
