7. TS’AI LUN invented
paper, he devised a way
of floating in water the
fibers from tree barks, old
rags and hemp waste and
allow the fibers to settle
and then drying them into
a sheet.

9. An activity that involves a selection of
preparation and marketing of printed
matter
It refers to the preparation and
distribution of written materials for
public use.
It involves writing, paper and printing.
15. About 1620 Willem Janszoon Blaeu in
Amsterdam added a counterweight to
the pressure bar in order to make the
platen rise automatically; this was the
so-called Dutch press, a copy of which
was to be the first press introduced into
North America, by Stephen Daye at
Cambridge, Massachusetts in 1639.
16. In 1811 Koenig and an associate, Andreas
Bauer, in another approach to the rotary
principle, designed a cylinder as a platen
bearing the sheet of paper and pressing it
against the type form placed on a flatbed
that moved to and fro. The rotation of the
cylinder was linked to the forward movement
of the bed but was disengaged when the bed
moved back to go under the inking rollers.

18. In 1818 Koenig and Bauer designed a double
press in which a sheet of paper printed on one
side under one of the cylinders passed to the
other cylinder, to be printed on the other
side. This was called a perfecting machine. In
1824 William Church added grippers to the
cylinder to pick up, hold, and then
automatically release the sheet of paper.
19. In 1844 Richard Hoe in the United States
patented his type revolving press, the
first rotary to be based on this principle.
It consisted of a cylinder of large
diameter, bearing columns of type
bracketed together on its outer surface;
pressure was provided by several small
cylinders, each of which was fed sheets
of paper by hand.
20. Printing is being revolutionized by
advances in technology, particularly in
the fields of automation, electronics
and computers. The combination of
computer technology and
photocomposition has revolutionized
typesetting machines
21. TYPESETTING - refers to the
asembly of letters into words,
and words into lines, in a form
suitable for multiple
reproduction by one of the
printing method.
22. Machines that can read copy typed
by authors or journalists and pass
information on via computer to a
photocomposing machine have
been developed. Computers can
store not only text but also
illustrations in digital form.
