									The Fundamentals About The
      Printing Process
Printing refers to the activity of
 reproducing diagrams, texts and/or
 pictures on plain surfaces. This process is
 accomplished using inks and printers. It
 could be carried out on small or massive
 scale.
Publishing primarily relies on it.
 Woodblock process was the earliest type
 of image and text reproduction. This
 elementary kind has gradually been
 replaced ever since with the effective
 contemporary printing press.
Printers are the major equipment used in
 this process. They produce depictions of
 electronic documents on media such as
 paper or on transparent films.
 Documents can be printed from
 scanners, memory cards, or digital
 cameras.
A classic inkjet printer has ink cartridges,
 stabilizer bar, belt, a print head stepper
 motor, and a print head. These
 components are collectively called the
 print head.
The print heads contain a string of
 nozzles, which sprinkle droplets of ink.
 Ink cartridge versions are reliant on
 make of the printer and its maker.
 Cartridges come in diverse combinations
 like black and single color. Stepper
 motors move ink cartridges and print
 heads. The motor moves them forwards
 and backwards across the material that
 needs to be printed on. Some printers
 have stepper motors that stop accidental
 movement of print heads when idle.
There are different techniques of
 printing. The most common ones include
 offset lithography, inkjet, flexography,
 dye transfer, laser, gravure, and pad
 printing.
Gravure technique is most suited for
 reproducing images onto fabrics. The
 main articles that can be printed using
 this technique include postage stamps,
 mail orders, catalogues, and magazines.
The quality of images produced by
 printers is greatly determined by the
 paper used. The ordinary copier papers
 do not provide bright and crisp images as
 the inkjet papers.

 The two major factors affecting the
 quality of images are brightness and
 absorption.
Paper brightness is determined by its
 surface. Rough papers scatter beams of
 light in many different directions.

This has the effect of making the paper
 look brighter making images printed on it
 appear bright too.
The other factor of worth considering is
 the absorption factor. Inks sprinkled on
 print papers should produce tight
 symmetrical spots with minimal
 dispersion. Papers must absorb as little
 ink into their surfaces as possible.
Excess absorption of ink scatters it out
 more. In case this takes place, the ink
 spread on a bigger region than it is
 supposed leading to blurred text and
 pictures particularly along the edges.
Printing has advanced a lot in the recent
 past. Several firms manufacture high
 quality printers, which can produce
 excellent prints very quickly. Printer
 costs are also reducing due to
 advancements in technology.
