Ten basic
publication formats are
derived from the Unigrid
structure.
Captions are set one or two modules wide (7 or 15 picas wide)
in 7/7, 7/8, or 8/9 Helvetica Regular or Medium, and may be either
roman or italic. This variety of weight, posture, and leading provides
flexibility to create a value and texture that complements and contrasts
with other typographic and pictorial elements. Captions are set
ragged-right, and this helps create a strong separation between text and
captions, as do contrasts between text and caption textures, weights,
and line lengths.
Major display type can be set in 12-, 18-, or 24-point Helvetica
Medium and is often positioned 10 points above the related text on
a horizontal band of white space, frequently 40 points high, running
above the text. The variety of display sizes gives the designer the
flexibility needed to create appropriate scale relationships between
display type, the size of the folder, image sizes, and density of text
type. The margin below the text type is always a spatial interval at least
20 points high.
The cover panels of all folders have a 100-point black band that
bleeds at the top and on both sides (Fig.
10-10
). Titles reverse from
this bar and are set in standard sizes of Helvetica Medium for park
names with fewer than twelve letters. When site designation and
location appear reversed from the black bar, these are set in 12/14 or
8/9 Helvetica Medium and align on the seventh grid module. Service
designations are the same size and align on the tenth grid module.
Cover panel type is always positioned 10 points down from the top
edge of the band. This horizontal black band with its standardized title
type becomes a consistent visual identification device for the National
Park Service.
Horizontal movement is accentuated through the placement
of the type, the horizontal margins, and internal bars that divide
the space into zones of information. These bars are 25 points wide
and correspond to the title bar. They may be complementary colors,
contrasting colors, or black. One bar is always placed across the bottom
of the folder. Display type is sometimes reversed from the bars.

Copy the Unigrid in Figure 10-8
onto transparent material and place it over these
folders to study the underlying structure of the
designs.
