or on disk. If a particular font isn’t available, the computer program will attempt to
match it with one that is. This can result in a map that looks quite different from
what you intended.
suitability for Reproduction
Before choosing a type style, it is helpful to know how the paper map will be repro-
duced, if it will be reduced, and even, if possible, the type of paper that will be
used. For maps that will be viewed on monitors or projected on screens, resolution
is important. Generally, the Modern typefaces with extremes of thick and thin are
considered less suitable for reduction than Oldstyle because the very thin lines may
be lost in reproduction. They also do not work well on monitors.
edItIng
Like written work, the text of maps must be edited. The importance of editing cannot

is to include misspelled words on it. The reader assumes that if the spelling is sloppy
