The Basics Of Modern Printing
Printing is the process of reproducing images and texts on various plain surfaces like paper. This
process is achieved using a printer and ink. It can be done on either large or small scale. Publishing
mainly relies on this process. The earliest form of text and picture reproduction was the Woodblock
process. This crude form has ever since been replaced with the efficient current day press.
Printers are the major devices utilized in this process. They generate portrays of electronic
documents on transparent films or on plain media like paper. Documents could be printed from
memory cards, digital cameras, or scanners. Typical inkjet printers have belt, print head stepper
motors, print heads, ink cartridges, and stabilizer bars. These constituents are collectively referred to
as print head.
The head contains a series of nozzles that sprinkle ink drops. Ink cartridge models are reliant on the
printer make and the producer. Cartridges come in different combinations like single color and black.
The print heads and ink cartridges are moved by the stepper motor. It moves them back and forth
across the material to be printed on. Some models contain stepper motors that prevent accidental
movement of the heads when not in use. There are many different printing techniques. The most
extensively used methods include dye transfer, laser, flexography, inkjet, flexography, pad, gravure,
and offset lithography printing. Gravure is most suitable for use on fabrics. The key prints that are
printed by use of this method include catalogues, postage stamps, mail orders, and magazines.
The quality of prints generated by printers is highly determined by the paper utilized. The normal
copier papers do not produce bright and crisp prints like inkjet papers. The 2 major factors that affect
the quality of prints are absorption and brightness. Paper brightness is dependent on its surface.
Rough surfaces scatter rays of light in many directions. This aspect has the effect of making papers
appear brighter making pictures printed on them also look bright.
The other element of significance is the absorption factor. Ink sprinkled on the papers should form
tight symmetrical dots with minimal dispersion. The papers must also absorb minimal ink into their
surfaces. A lot of absorption makes inks to scatter out more. If this occurs, the ink covers a bigger
area than expected leading to blurred images and text particularly at 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
