Transfer printing is the term used to describe textile and related printing processes in which the design is first printed on to a flexible non-textile substrate and later transferred by a separate process to a textile.

3. Introduction
o The printing is described as localized dyeing, dyes or pigment are applied
locally or discontinuously to produce the various designs.
o Printing is the production of all active designs with well defined boundaries
made by the artistic arrangement of a motif is one or more colors.
o Printing is a process for reproducing text and image, typically with ink on
paper using a printing press.

4. What is Transfer Printing?
o It is the term used to describe textile and related printing
processes in which the design is first printed on to a flexible non-
textile substrate and later transferred by a separate process to a
textile.

5. Why Transfer Printing?
o Designs may be printed and stored on a relatively cheap and
nonbulky substrate.
o The production of short-run repeat orders.
o Many complex designs can be produced more easily and accurately
on paper than on textiles.
o Enable textile printing to be carried out using simple, relatively
inexpensive equipment with modest space requirements, without
effluent production or any need for washing-off.

6. Advanced styles of transfer textile printing
o Transfer Printing
 Sublimation Transfer
 Melt Transfer
 Film Release Transfer
 Wet Transfer

7. 1. Sublimation/Vapor-Phase (dry transfer printing)
o During the sublimation printing process, an image is digitally
printed in reverse with sublimation toners or inks onto media.
o That image is then placed on top of a fabric and subjected to high
heat and pressure to form a heat press.
o The sublimation toners or inks sublimate – the inks go from a solid
state to a gaseous state without becoming liquid in between and
flow into the fabric, dyeing the threads.

9. Equipment needed for Sublimation Transfer Printing
o A dye sublimation printer
o Sublimation paper
o Photo processing software
o A heat transfer press
o A digital camera or scanner to transfer design

10. Yarn type used for sublimate transfer printing
o It is high-recommended that 100% Polyester garments are used for
sublimation printing.
o 100% polyester is best for a vibrant design resulting in a no-loss
image resolution.
o Polyester blend fabrics; such as our 65% Polyester / 35% Cotton
Blend; can also be used but will result in a retro/vintage look.

11. 1. Dye sublimation is done using a digital image, a dye sublimation
printer and dye.
2. The image is transferred to dye sublimation paper and the ink is
transferred to the fabric.
3. The image retain the digital quality is permanently embedded into
the fabric.
How it is done?

14. 2. Melt/Heat Transfer printing
o The design is printed on paper using a waxy ink, and a hot iron
applied to its reverse face presses the paper against the fabric.
o The ink melts on to the fabric in contact with it.
o This was the basis of the first commercially successful transfer
process, known as Star printing, developed in Italy in the late 1940s.
o It is used in the so-called ‘hot-split’ transfer papers extensively
used today in garment decoration.

15. Melt Transfer printing process
1. The ink layer of the transfer is based on dyes and waxes.
2. The ink layer is embedded in the fabric by melt and pressure, and
part of the ink is transferred to the fibers and then post-treated
according to the properties of the dye.
3. When it employed, a large pressure is required and the transfer rat
of the dye increases as the pressure is increases.

16. Yarn type used for melt Transfer printing
o Melt transfer printing process could be used to print a range of
natural and synthetic fabrics with appropriate selection of dyes and
chemical auxiliaries.

17. 3. Film Release Transfer printing
o It is similar to melt transfer with the difference that the design is
held in an ink layer which is transferred completely to the textile
from a release paper using heat and pressure.
o As the name implies, film release deposits the printed image as a
virtually coherent film on the textile material.

18. Film Release Printing Working Process
1. Adhesion forces are developed between the film and the textile
which are stronger than those between the film and the paper.
2. The process has been developed for the printing of both
continuous web and garment panel units, but is used almost
exclusively for the latter purpose.
3. In commercial importance it is comparable with sublimation
transfer printing.

21. What is Wet Transfer Printing?
o The principle behind wet transfer processes is the use of water as
the medium through which dye diffuses in passing from the paper to
the fabric.
o Water-soluble dyes are incorporated into a printing ink which is used
to produce a design on paper.
o The design is transferred to a moistened textile using carefully
regulated contact pressure.
o The dye transfers by diffusion through the aqueous medium.

22. Wet Transfer printing process
1. Printing the required design on a selected grade of paper, using
specially chosen dyes dispersed in a suitable paper printing medium.
2. Impregnating the fabric with an aqueous solution which may contain
a dye fixation catalyst and a thickener.
3. Bringing the printed paper and the impregnated fabric into close
conformity, by applying pressure, and maintaining this conformity
under pressure for a period time.

23. Yarn type used for wet Transfer printing
o Wet transfer processes were developed for printing wool with acid
or reactive dyes.
o Mostly used for fully fashioned knitted woollen garment panels.
o For cotton goods and may be effectively used for wool blends, nylon
and acrylic fabrics.

24. Advantages of Transfer Printing
o It gives good prints on well prepared knitted goods.
o No adverse effect on fabric’s feel and luster.
o It allows excellent dye penetration into the fiber ( because transfer
takes place at very high temperature).
o Steaming, Washing, drying etc are not necessary.
o Quicker reaction to changes in fashions.

25. Disadvantages of Transfer Printing
o There is some restriction of the production of deep shade
o High temp and pressure is required
o Once printed cannot be corrected
o Only limited dyestuff can be used for transfer printing
o Lower production speed due to existing transfer calendars
o Storage of large quantities of paper over prolonged period of time is
a risk.

26. o In textile application the transfer printing is one of the advanced
methods since the printing process is performed without steaming,
washing, drying, its quicker reaction to changes in fashions and fast
delivery time of response for customer's.
