4. TEXTILE PRINTING
Textile Printing can also be defined
as localized dyeing defined as the
application of dye or pigment in a
different pattern on the fabric and
by subsequent after treatment of
fixing the dye or pigment to get a
particular design.

5. Textile Printing Machine:
There are Different Types of Textile Printing Machine,
• Block textile printing machine
• Roller printing machine
• Stencil printing machine
• Digital textile printing machine

6. Hand Block Printing:
This process is the earliest, simplest and slowest
of all printing methods. A design is drawn on, or
transferred to, prepared wooden blocks. A
separate block is required for each distinct color
in the design. A block cutter carves out the
wood around the heavier masses first, leaving
the finer and more delicate work until the last
so as to avoid any risk of injuring it when the
coarser parts are cut. When finished, the block
has the appearance of a flat relief carving, with
the design standing out. Fine details, difficult to
cut in wood, are built up in strips of brass or
copper, which is bent to shape and driven
edgewise into the flat surface of the block.

7. Hand Block Printing Cont:
This method is known as coppering. The printer
applies color to the block and presses it firmly
and steadily on the cloth, striking it smartly on
the back with a wooden mallet. The second
impression is made in the same way, the printer
taking care to see that it registers exactly with
the first. Pins at each corner of the block join
up exactly, so that the pattern can continue
without a break. Each succeeding impression is
made in precisely the same manner until the
length of cloth is fully printed. The cloth is the
wound over drying rollers. If the pattern
contains several colors the cloth is first printed
throughout with one color, dried, and then
printed with the next.

8. Advantages of Block Textile Printing Machine:
• Simple method of printing
• No expensive equipment required
• No limitation in repeat of size of style
• Prints produced have great
Disadvantages of Block Textile Printing Machine:
• Involves much manual work
• Method is slow and therefore low output
• Good skilled labors needed for multi color design
• Fine and delicate designs hard to produce

9. Roller Printing:
Roller printing was highly productive, 10,000 to
12,000 yards being commonly printed in one day of
ten hours by a single-color machine. It is capable of
reproducing every style of design, ranging from the
fine delicate lines of copperplate engraving to the
small repeats and limited colors of the parroting to
the broadest effects of block printing with repeats
from 1 in to 80 inches. It is precise, so each portion
of an elaborate multicolor pattern can be fitted
into its proper place without faulty joints at the
points of repetition.

10. Advantages of Roller Printing Machine:
• Large quantities of fabric at the rate of 914-3658m per hour can
be printed.
• Faulty joints or joint marks are absent.
• Fine sharp outlines and good prints can be obtained which is
difficult to get in block printing
Disadvantages of Roller Printing Machine:
• Not economical for short run of fabrics.
• Difficult to produce blotch designs.
• Repeat of design limited to the size of the rollers.
• Setup cost of roller printing m/c is high.

11. Stencil Printing:
A pattern is cut from a sheet of stout paper or
thin metal with a sharp pointed knife, the
uncut portions representing the part that will
be left uncolored. The sheet is laid on the
fabric and color is brushed through its inter
sties. The peculiarity of stenciled patterns is
that they have to be held together by ties. For
instance, a complete circle cannot be cut
without its center dropping out, so its outline
has to be interrupted at convenient points by
ties or uncut portions. This limitation
influences the design.

12. Advantages of Stencil Printing Machine:
• Simple and cost effective.
• Stencils can be made rapidly and can be used
for small orders.
• Color combination is good in it.
Disadvantages of Stencil Printing Machine:
• Good design is difficult to obtain.
• Process is laborious.
• Not suitable for large scale production.

13. Digital Textile Printing Machine:
Digital textile printing is described as any ink jet
based method of printing colorants onto fabric.
Most notably, digital textile printing is referred to
when identifying either printing smaller designs
onto garments (T-shirts, dresses, promotional
wear; abbreviated as DTG, which stands for direct
to garment and printing larger designs onto large
format rolls of textile. The latter is a growing
trend in visual communication, where
advertisement and corporate branding is printed
onto polyester media. Examples are: flags,
banners, signs and retail graphics.

14. Advantages Digital Printing Machine:
•High print quality.
• Lower water and power consumption.
• Less Chemical waste.
• Large repeat size are possible.
• Reduced production space requirements.
Disadvantages of Digital Printing Machine:
• The printing speed is low.
• Ink cost is very high.
• But it decreasing regularly.
• Color accuracy maintain is very difficult.

15. Importance of Printing Machineries:
The rise in technology has seen development in every aspect of human
life. The printing industry is an integral part of every working unit like
the service industry, manufacturing industry and every other
commercial aspect. The printing industry is the publishing agent
where from small scale printing process to large scale printing process
takes place. It has played an important role in helping the printing
industry to keep up with the requirements. From small scale printings
to commercial holdings and banners, printing machines could be
termed as the machine which brought revolution in the printing
industry. To help the printing industry to keep up with the daily
requirements there are several printing machines and technique, and
they are Digital printing, offset printing and letter press printing.

16. Conclusion:
Printing machineries have a great
impact in textile industry. Printing is
the ornament for any stylish
production. So printing machineries
have usefulness in our textile
industry. Production is not possible
accurately without those
machineries.
