Newspaper
presses are very similar to normal offset
presses except the printing units are arranged
vertically instead of horizontally. This is
done to conserve fl oor space due to the vast
amount of pages to print. Keep in mind that
when a newspa-per is printed, the whole paper
is printed in one pass.
The
roll stands are usually in the basement and
normally hold 2 or 3 rolls to a stand. Splicers
are the fl ying type. Large, high speed news
webs run several webs at the same time in
order to print one newspaper. Most news presses,
today, are not heatset but use vegetable oil
(soy, etc.) inks and dry by absorption. In
fact, newspaper printers use the majority
of soy based ink. This is not done solely
for ecological reasons, but for decreased
ruboff, runnability, etc. Newspaper presses
use a combination of 4-color and single color
printing units. The cover pages of each section
are normally printed in color (front and back
page) with the inside pages printed in black.
The typical newspaper press contains many
combination folders to fold the various sections.
Following printing and the collection of various
sections, the newspaper is fed to a mail room
for further processing such as insertion of
separate sections (advertising, etc.), mailing
and fi nal distribution.
