one color to another color,
from black to white, or from
color to the absence of color.

grommet:
A small metal or plastic
ring that is inserted into
a hole made in another piece
of material. It prevents

A freestanding sign that
is not secured to a foundation
or other secondary support
structure.

like an "H") that allows
for the mounting of neon
tubing within the lettering
itself.
hairline joint:
The thinnest possible joint
between two edges.
halation:
A halo-like effect can result
from extreme contrast between
adjacent illuminated and
non-illuminated portions
of a sign. The light appears
to spread or bleed across
the non-illuminated area,
making it more difficult
for the viewer to focus on
the sign and its message.
halftone:
The process by which a continuous
tone image such as a photograph
is reproduced and simulated
using a pattern of printed
or silk screened dots of
varying size and equal spacing.
At a normal viewing distance
the reproduced image appears
as continuous tone.

A glowing ring of light surrounding
a object such as a channel
letter which has been lit
from behind. (See also halo

to reflect off the mounting
surface. The result is that
the sign appears to be surrounded
by a halo of light.

sign mounted to a wall or
pole and hung from a bracket
or support arm. (Also known
as a projecting sign.)
heat color-transfer:
A process of applying color
to fabric whereby a pigmented
resin is activated by heat
and then pulled into the
fabric with a vacuum applicator.
heat-bending:
The process of heating a
piece of material such as
PVC, acrylic or glass tubing
in order to make it malleable
enough to bend and shape.
height:
The measured distance between
the highest point of a sign
to the highest point of the
grade underneath the sign.
height above grade:
The measured distance between
the lowest portion of a sign
and the highest point of
the grade underneath. (Also
called clearance.)
high-rise sign:
A freestanding sign tall
enough to be seen from a
distance, especially by motorists.
hinged side:
The hinged side of a double-faced
sign. When opened it provides
access to the interior of
the sign allowing for the
inspection and servicing
of its internal components.
(See also access door.)
hue: A
given color's tendency towards
any of the four base wavelengths
of visible light: red, yellow,
blue and green. For example,
if yellow appears more dominate
in an orange colored ink,
then that color orange would
be said to have a yellowish
hue. Hue is one of the three
attributes of color along
with brightness and saturation.
