• Major Processes
• Relief
• A modeled work that is raised (or lowered) from a
  flat background.
• Cuneiform by the Sumerians 6000 years ago.
• Wood block printing 200 C.E.
• Movable type printing 1040 C.E. (Gutenberg
  1450)
• Intaglio (in-tal-yo) 1430
• Rotary printing press 1843
• Lithography (offset printing) 1796
• The source and destination are not on raised
  surfaces
• Grease and water do not readily mix
• A chemical process
• Most modern books and newspapers

By 593 A.D., the first printing press was
invented in China, and the first printed
newspaper was available in Beijing in 700 A.D. It
was a woodblock printing. And the Diamond Sutra,
the earliest known complete woodblock printed
book with illustrations was printed in China in
868 A.D. And Chinese printer Bi Sheng invented
movable type in 1041 A.D. in China.

• Screen Printing (1000 C.E., China 1907 England)
• Mainly billboards, package labels, fabric designs
• Uses a woven mesh (a screen) to support an ink
  blocking stencil.
• The stencil forms open areas of mesh that
  transfer ink as a sharp-edged image onto a
  substrate.
• A roller or squeegee is moved across the screen
  stencil forcing or pumping ink past the threads
  of the woven mesh in the open areas.
• Electrostatic (1938 / 1960s)
• Photocopier, Laser Printer
• Opposite charges attract
• Ink Jet (1980s)
• Use a series of nozzles to spray ink directly on
  paper

• Photographic Communication
• The process of using photographs to communicate a
  message
• Photography capturing light on a
  light-sensitive material such as film or
  electronic sensor
• As a usable process, 1820s
• Includes photographs, slides, and motion pictures

Photographic Communication

Communication Technology

• Telecommunication
• Communicating over a distance
• Tele Greek, far off Communicare Latin,
  to share
• Rely on the principles of electricity and
  magnetism
• 2 types
• Hardwired systems (telephone, cable, fiber-optic)
• Broadcast systems (radio and t.v., mobile phones)
• Point-to-point
• One transmitter and one receiver
• Broadcast
• One powerful transmitter to numerous receivers

  mechanical elements

Telecommunications
11
Communication Technology

• Telegraph (mid 1830s)
• First instrument used to send messages by means
  of wires and electric current
• A device interrupts the flow of a current through
  a wire
• Uses shorter and longer bursts of current to
  represent letters
• Device at receiving end converted electrical
  signal into clicks
• Operator/mechanical printer converted clicks into
  words
• Telegram wires over land
• Cable wires under water
• Telephone (1876 Bell and Gray)
• Greek tele far, phone sound
