3. PRINTING
Printing is the process of applying colour to fabric in definite patterns or
designs. In properly printed fabrics the colour is bonded with the fiber, so
as to resist washing and friction. Textile printing is related to dyeing but in
dyeing ,the whole fabric is uniformly covered with one colour, On the
other hand,in printing one or more colours are applied to it in certain
parts only.In printing, wooden blocks, stencils,rollers, or silk-screens can
be used to place colours on the fabric.

4. DIFFERENCE BETWEEN AUTOMATIC
PRINT & HAND PRINT
Automatic Print Hand Print
Accuracy No Accuracy
Limited Production No Limited Production
Production is high Production is Low
Depends on m/c capacity It is manually print
Capacity is 9 colors Variety colors print

5. DIFFERENT METHOD OF PRINTING
There are three basic method to printing a color on a fabric
• Direct printing
• Resist printing
• Discharge printing

6. DIRECT PRINTING
• In this type of printing dye is applied onto the fabric by stencil, screen,roller etc.
• The dye is imprinted on the fabric in paste form and any desired pattern may be
produced.
• Example:-Block Printing, Roller Printing, Screen Printing etc.

7. DISCHARGE PRINTING
• In this method the fabric is dyed and then printed with a chemical that will destroy
the color in designed areas.
• Sometimes the base color is removed and another color printed in its place.

8. RESIST PRINTING
• In this method bleached fabric are printed with a resist paste.
• The dye will only affect only the parts that are not covered by the resist paste .
• After the fabric has passed through a subsequent dyeing process the resist paste is
removed, leaving a pattern on a dark background.

9. DIFFERENT TYPES OF PRINTING
 BLOCK PRINTING
 ROLLER PRINTING
 SCREEN PRINTING
 FLAT-SCREEN PRINTING
ROTARY PRINTING
TRANSFER PRINTING
STENCIL PRINTING
DIGITAL PRINTING
BATIK PRINTING
TIE & DYE

10. BLOCK PRINTING
• It is the oldest and simplest way of printing
• In this method a wooden block with a raised pattern on the surface was dipped into
the printing colorant and then pressed face down on to fabric.
• The desired pattern was obtained by repeating the process using different colors.
 • Generally the wooden block is carved out of hand
• Printing is done manually

11. BLOCK PRINTING
ADVANTAGES DISADVANTAGES
Simple method of printing Involves much manual work
No expensive equipment required Method is slow and therefore low output
No limitation in repeat of size of style Good skilled labors needed for multi color
design
Prints produced have great decorative
value and stamp of craftsmanship
Fine and delicate designs hard to produce

12. ROLLER PRINTING
• • It is the machine method of printing designs on cloths by engraved rollers.
• • The design is engraved on the surface of a metal roller, to which dye is applied,
and the excess is scraped off the roller's surface, leaving dye in the engraved
sections. When it rolls across the fabric, the dye on the roller transfers to the fabric.

13. ROLLER PRINTING
ADVANTAGES DISADVANTAGES
Large quantities of fabric at the rate of
914-3658m per hour can be printed
Not economical for short run of fabrics.
Faulty joints or joint marks are absent. Difficult to produce blotch designs
Fine sharp outlines and good prints can
be obtained which is difficult to get in
block printing.
Repeat of design limited to the size of the
rollers.

14. STENCIL PRINTING
It is one of the oldest way of printing.
 In it color is applied to the fabric by brushing or spraying the interstices of a pattern
cut out from a flat sheet of metal or waterproof paper or plastic sheet or laminated
sheet.
 A stencil is prepared by cutting out a design from a flat sheet of paper, metal, or
plastic.

15. STENCIL PRINTING
ADVANTAGES DISADVANTAGES
Simple and cost effective. Good design is difficult to obtain.
Stencils can be made rapidly and can be
used for small orders.
Process is laborious.
Color combination is good in it.. Not suitable for large scale production.

16. SCREEN PRINTING
• It involves the application of the printing paste through a fine screen placed in
contact with the fabric to be printed.
• A design is created in reverse on the screen by blocking areas of the screen with a
material such as an opaque paint.
• The screen is then placed over the fabric and the printing paste is forced through
the open areas of the screen using a flexible synthetic rubber or steel blade known
as a squeegee.

17. SCREEN PRINTING
ADVANTAGES DISADVANTAGES
Simple and cost effective. For high production large no of tables
required.
Quick pattern making. Delicate shading difficult to obtain.
16 colors can be used in a design. Screen clogging may be there in fine areas.

18. FLAT-SCREEN PRINTING
• It is the advanced version of screen printing by using automatic m/c to do work .
• It consists of printing table, conveyor belt, number of screens, mechanism to print
on the fabric, etc.

19. FLAT SCREEN PRINTING
ADVANTAGES DISADVANTAGES
Greater production than manual screen
printing.
A big setup required for more number of
screens.
Printing with different repeat can be made
easily.
Prints with more colors may not be
possible.
Good print is obtained . Printing paste not evenly controlled.

20. TRANSFER PRINTING
It is a indirect method of printing in which dyes are transferred from paper to a
thermoplastic fabric under controlled conditions of temperature, time and pressure.
 The image is first engraved on a copper plate.
 Then pigment is applied on these plates.
The image is then transferred to a piece of paper, with a layer of glue applied .
This is then placed on the fabric and heat and pressure applied which fixes the print
onto fabric.

21. TRANSFER PRINTING
ADVANTAGES DISADVANTAGES
Operation is simple and no expensive m/c is
required.
Process applicable to synthetic fabric like
polyester.
No after treatment of fabric required. Color range is limited.
Print on fabric is of excellent quality. Cost of printed paper high.

22. BATIK PRINTING
Originated on island of Java and is a cottage based industry.
 Batik is derived from word “AMBATIK”
 The resist-dyeing process, whereby designs are made with wax on a fabric which is
subsequently immersed in a dye to absorb the color on the unwaxed portions, is
known as batik printing.
 Special feature is the fine lines of color running irregularly across the fabric.

23. BATIK PRINTING
ADVANTAGES DISADVANTAGES
Gives a good artistic effect Laborious
Cheap printing Time taking
Greater artistic design Cracking effect
Fabric has a rich and graceful appearance Dye should be applied at low temperature
than wax.

24. ROTARY SCREEN PRINTING
Rotary screen printing involves a series of revolving metal cylinder , each with
revolving screens, each with a stationary squeegee inside which forces the print
paste onto the fabric.
Twenty or more colours can be printed at the same time.
The process is much quicker and more efficient than flat screen printing .

25. PHOTO PRINTING
• In this type of printing the fabric is coated with a chemical ( Liquid
photo emulsion) that is sensitive to light and then any photograph may
be printed on it.
• Blueprinting is one such technique which is used very frequently.

26. TIE & DYE
Tie-dye is a process of resist dyeing textiles or clothing which is made from knit or
woven fabric, usually cotton; typically using bright colors. It is a modern version of
traditional dyeing methods used in many cultures throughout the world.
It is same as that of batik printing but here the dye is resisted by knots that are tied
in the cloth before it is immersed in dye bath.
 The outside of the knotted portion is dyed, but inside is not penetrated if the knot
is firmly tied.
 This gives a characteristic blurred or mottled effect .

27. MATERIALS NEEDS FOR TIE-DYE:
• Dyes – buy them at the craft store
• White T-shirt or cotton material
• Rubber bands
• Plastic Bag
• Plastic Tubs

28. TIE & DYE
ADVANTAGE DISADVANTAGE
Interesting design created on fabric Costly
No m/c cost is there Laborious
Time taking

29. DUPLEX PRINTS
• These are fabrics in which both sides of the fabric are printed.
• They are made to imitate more costly woven yarn-dyed design effects such as
stripes, checks and plaids.They are rarely used because of the high cost of printing
both sides of a fabric .

30. DIGITAL PRINTING
• The process of reproducing digital images on physical surfaces is called Digital
Printing. The physical surfaces can be in any form like a common paper, cloth,
plastic, a photographic paper, film, etc.

31. DIGITAL PRINTING
It is the more advanced type of printing.
• This includes :-
• Jet spray printing
• Electrostatic printing
• Photo printing
• Differential printing

32. Digital Printing refers to method of printing from a digital-based image directly
to a verity of media.
Inkjet Technology Laser Technology
Inks Toner

33. FEATURE OF DIGITAL DIRECT PRINTING
• Print with computer-operated digital print, ideally suited for large-scale prints.
• Colors are sprayed on and made durable with a hardener. The fabrics can still be felt when
touching the design.
• Results in a relaxed “vintage look”. The design looks a bit faded, don’t expect brash colors.
• Digital direct is not available for all of our products.

34. Comparison between Digital Textile Printing and
Tradition Printing Methods
• Has greater Flexibility.
• Easy Application.
• Can Be used for Versatile purposes.
• Take less time.
• Having more colors Along with
photo realistic effects.
• Present a variety of exclusive textile
designs.
• Less flexibility.
• Less convenient in applying .
• Can be used for limited purposes.
• Take more time.
• Comparatively less colors and absent of
photorealistic effect.
• Having less no. of regarding designs.

38. ADVANTAGES OF DIGITAL PRINTING
• The image can be printed all over the entire item, with no difficulty in printing all the way to
the edges.
• Colors can be extraordinarily brilliant due to the bonding of the dye to the transparent
fibers of the synthetic fabric.
• It is time saving for sampling as compare to rotary process.
• Truly continuous tones can be achieved that are equivalent to photographs, without the
use special techniques such as half-screen printing.
• Time saving for sampling only.
