1. Printing Machines
Printing machines are growing in large numbers in the industrial set up of the economy.
Every industry is using printing techniques and processes for effective communication. There
were revolutionary changes in the early 90's in the printing industry as it became a service
industry and now is very much flourishing. The popular printing techniques are Letter Press
Printing, one of the oldest technique, Offset Printing and recently introduced Digital Printing,
which is getting a boom in the printing industry. Some of the most used printing machines are
label printing machine, flexo printing machine, CD printing machine, etc.
1. Digital Printing Machine
Digital Printing Machines have gained popularity for short to
medium run jobs requiring high quality, clarity and finer printing.
These printers deliver vibrant image quality and allow up to 8
color printing.
These affordable and high performance machines are
revolutionizing the printing industry by providing cost-effective
and fine printing solutions. Digital printing equipment ensure fast
turnaround time because of on-demand services. The techniques allows print on demand for
publishing books and is ideally suited to publish small print run of posters and books.
2. Pad Printing Machine
Pad Printing Machine is a type of offset printing providing fast and
high clarity printing. This technique of printing is one of the most
versatile and used to printing three-dimensional objects and
compound angles. Pad printer reigns supreme in industrial printing
for high quality and fine printing on various materials including
plastic, rubber, metal, ceramic. The printing speed and quality of
pad printing machines depends on the kind, thickness of
stock/paper, type of inks used and other operating conditions. The
plate is as important for pad printing as stylus for screen printing.
Pad printing equipment prints the image that is etched on the plate that communicates with
ink cup that fill the etched image with ink, then image is transferred on the surface through
pad.

2. 3. Embossing Machine
Embossing Printing machines are used by the printing industry for
fine printing on a number of products. These machines help to
create a three-dimensional image or effect on different substrates.
Embossing can be done on different materials including paper,
textile, metals etc. Embossing machines are also used to enhance
the look of aluminium foils. The machines are equipped with
embossing modes in order to accommodate different materials.
Thermographic machines can also be used for the raise letter
effect.
4. Thermographic Printing Machine
Thermographic Printing Machines provide a raised lettering effect,
as commonly seen in business cards and are widely used by the
commercial printing industry. These machines also provide a less
expensive alternative to foil stamping, embossing or UV coating.
Thermographic Printing Process
These machines take thermography resin powder, sprinkle it over
wet ink and bake it. This allows the powder to stick to the printed
areas. Excess powder on non image areas is removed off the paper/substrate before the
heating process. The sheet is finally cooled after the heating process and the melted powder
hardens into raised thermographic image.
5. Letterpress Printing Machine
Letterpress Printing is all time triumphant printing technique that
can attach sensuous and stirring quality to design & art and
lavishes vivid quality & nostalgic feeling that can not be captured
by other techniques. Letterpress Machine is also known as relief or
typographic printing machines, which are widely used to make
copies of images by repeated direct impression of an inked, raised
surface against rolls or sheets of paper. The substances that are
used in letterpress printing are identical to those used in
lithography, include film developers and fixers, inks, and blanket
and roller washes. The use of letterpress has been on the decline because of the advent of
more advanced & efficient printing presses like the Offset Printing Machine, lithographic
press or the flexographic press. But after incorporation of photo polymer plates has paved the
way for letterpress printing to revive its existence & hold sway even in 21st century

3. 6. Flexographic Printing Machine
Flexographic Printing Machines produce high quality, finer and
clear impressions on different substrates. These machines are
popular because of the simple operation and easy adaptation for
the use of water-based inks. Flexo printing is inexpensive and a
simple form of printing method generally applied for package
printing, moreover flexographic printer is good enough to produce
excellent quality impression on several different materials. These
flexo printing machines are popularly used for printing on
materials including plastic, paper, foils, acetate films, this is done
by use of rubber/plastic printing plates. Flexo printing machine has
a high speed printing process and makes use of fast-drying inks. Such printing machine can
print on a range of absorbent & non-absorbent materials and can print in continuous patterns.
7. Electrostatic Printing Machine
Electrostatic Printing Machines use electrostatic forces to form the
image in powder or ink directly on the surface to be printed.
Electrostatic printing machine has become so popular because of
high speed and cost effectiveness. Electrostatic printer is
particularly used by cartographers and publishers in order to print
maps & small books and ideal for small scale printing projects.
Electrostatic printers are capable of producing constantly classic
quality of print over a long period without making any changes to
the setting of the printers. Electrostatic printing machine is
particularly appropriate for printing multicolor topographic maps
and its quality is unparalleled. electrostatic printing machines that are reliable, inexpensive
and provides excellent resolution and printing quality, are required.
8. Screen Printing Machine
Screen Printing Machine is one of the most versatile Printing
Machines, compatible to work on a number of surfaces including
textiles, ceramics, metal, wood, paper, glass, and plastic. Screen
print machines have an edge over other print processes in the sense
that they can print on substrates of any shape, thickness and size.
Screen printing machines are capable of offering exciting effects
that can not be possible with other printing methods. This happens
due to broad range of dyes & inks which are five in types such as
solvent, water, and solvent plastisol, water plastisol, and UV
curable. Screen printers are an ideal choice and an economical
way of printing when you need to produce nameplates, signs, labels, shirts, t-shirts, and other
articles in large volumes.

4. 9. Offset Printing Machine
Offset Printing Machine has been widely put to various
applications. It is by far the most dominant form of commercial
printing technique, widely in use because of its unparalleled
quality with respect to voluminous production and paper costs.
These machines have a high set up cost but the printing process is
comparatively cheaper. Offset printing is also known as a
lithographic printing, provides vivid and sharper images and high
volume commercial printing that stands out offset printers from
others though digital printing crept into the printing world.
Flexography is still extant and used in label, envelop & ticket
printing but offset printing technology remains unbeatable.
10. Gravure Printing Machine
Gravure printing technique is used for long run printing with
sharper, fine and clear images. It is generally used for high-volume
printing of packaging, wallpaper, and giftwraps using fast-drying
inks. Although not widely used, gravure printing also finds
application in printing magazines, greeting cards, and high-volume
advertising print campaigns.
Operations Required in a Gravure Printing Services:
 Image Preparation
 Cylinder Preparation
 Printing
 Finishing
