Press In Delhi , Gurgaon India
Now a days use of
offset printing is increasing day by day . One of the
important functions in the printing
process is prepress production. This stage makes sure that all
files are correctly processed in preparation for printing. This includes
converting to the proper CMYK color model , finalizing the files, and
creating plates for each color of the job to be run on the press.
Offset printing is a commonly used printing technique in which the inked image
is transferred (or "offset") from a plate to a rubber blanket, then
to the printing surface. When used in combination with the lithographics process,
which is based on the repulsion of oil and water, the
offset technique employs a flat ( plainographic )
image carrier on which the image to be printed obtains ink from ink rollers,
while the non-printing area attracts a water-based film (called "fountain
solution"), keeping the non-printing areas ink-free. The modern
"web" process feeds a large reel of paper through a large press
machine in several parts, typically for several metres, which then prints
continuously as the paper is fed through.
Advantages
of offset printing compared to other printing methods include:
·
consistent high image quality. Offset printing produces sharp and clean
images and type more easily than, for example, letterpress printing ; this
is because the rubber blanket conforms to the texture of the printing surface;
·
quick and easy production of printing plates;
·
longer printing plate life than on direct litho presses because
there is no direct contact between the plate and the printing surface. Properly
developed plates used with optimized inks and fountain solution may achieve run
lengths of more than a million impressions;
·
cost. Offset printing is the cheapest method for producing high
quality prints in commercial printing quantities;
·
ability to adjust the amount of ink on the fountain roller with
screw keys. Most commonly, a metal blade controls the amount of ink transferred
from the ink trough to the fountain roller. By adjusting the screws, the
operator alters the gap between the blade and the fountain roller, increasing
or decreasing the amount of ink applied to the roller in certain areas. This
consequently modifies the density of the colour in the respective area of the
image. On older machines one adjusts the screws manually, but on modern
machines the screw keys are operated electronically by the printer controlling
the machine, enabling a much more precise result
