Sublimation method depends on the use of a volatile dye in the printed design. When the paper is heated the dye is preferentially adsorbed from the vapour phase by the textile material with which the heated paper is held in contact. This is commercially the most important of the transfer-printing methods. Dye sublimation allows photo lab quality picture printing. During the dye sublimation printing process, an image is digitally printed in reverse with dye sublimation toners or inks on to media.

8. Normally, as matter is heated, it progresses
through the stages of solid, liquid, then gas.
The process of sublimation involves taking
matter directly from the solid state to the
gaseous state, without becoming a liquid in
the process.
With a dye sublimation printer, this process
allows for ink to be dyed into fabric via heat,
which makes the dye permanent and allows
for photo-realistic images on
fabrics.

10. Dye sublimation can be used to make a variety
of patches for a diverse range of products.
Since there is no extra cost associated with
adding different colors, you don't have to choose
a 1 or 2-color image to save money.
It also isn't any more expensive to have full
coverage color than spot color.
This means you can have work shirts, club hats,
and many other items that look great but don't
cost more.
Application area

11. Application
Dye sublimation is often done on patches because they can then be
used on a multitude
of products, including:
• Work shirts and jackets
• Promotional items
• Merchandise for valued customers
• Event T-shirts and hats
• Uniforms for EMTs, police, firefighters, and municipalities
• Hats, shirts, and jackets for cycling groups, motorcycle clubs, sports
teams, bands, scout troops, and many others
Product wise
•Shirts
• Hats
• Key rings
• Lapel pins
Or, you can order the patches on their own and have them attached to
your own products, such as motorcycle jackets or uniforms.

12. dye sublimation process by sereen
Screen-printing and other processes for printing
images on fabric usually wear off before too long.
By using the dye sublimation process, you save
money as well as the environment because the
images last just as long as the Tshirts, hats, and other
materials the images are printed on.

13. Benefit of Dye Sublimation
Other processes to transfer images to fabric
include screen-printing, embroidery, dyes,
washes, and appliqués.
The problem with these processes is that the
image doesn't last or the process is
expensive, or both.
Dye Sublimation allows you to get high
quality at an affordable price.

14. Dye sublimation Printing
Dye sublimation allows photo lab quality picture printing.
During the dye sublimation printing process, an image is
digitally printed in reverse with dye sublimation toners or
inks on to media.
•That image is then placed on top of a fabric and subjected
to high heat and pressure to form a heat press.
•The dye 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.
•This creates a gentle gradation of color and does not
distort or fade overtime.

15. The sublimation name is applied because the dye transitions
between the solid and gas states without going through a
liquid stage. Many consumer and professional dye-
sublimation printers are designed and used for
producing photographic prints.
Sublimation printing process is that process which uses heat
to transfer dye on to medium materials such as a piece of
special paper and use heat to transfer the picture from the
paper to the fabric
The dye sublimation inks are a pigment suspended in a
liquid solvent, like water. The images are initially printed on
coated heat-resistant transfer paper as a reverse image of
the final design, which is then transferred onto polyester
fabric in a heat press operating at a temperature around 180
to 210 C (375 F). Under high temperature and pressure, the
dye turns into a gas and permeates the fabric and then
solidifies into its fibers.

17. Sublimation Sampling Process
Sublimation sampling can be done on Digital printing machine. But
digital is not production friendly due to more lead time and cost per
meter is high.
We can do production using Roller printing machine only for bigger
run.
Process-the required design is 1st printed on paper on a roller printing
machine for bulk production and then this paper along with the fabric
sandwich together and passed thru heated continues paper press to
transfer the print from paper to fabric.
Roller printing machine is a machine where copper rolls are used for
printing and any design with multiple color merging, ombray effect can
be achieved for bulk production, since the copper roll are very- very
expensive so this printing machine is no longer used in Indian textile
industry but frequently used in china and Korea to achieve excellent
print result in heat transfer/sublimation print

18. Any print that digital printing machine produced and
rotary can’t do, can be achieved using roller printing
machine thru sublimation process.
The combination of heat and pressure cause the
sublimation ink to convert into a gas, which is received
simultaneously by the substrate’s opened polymers. (This
is an over-simplified explanation of the process, but it
works for our purposes.) After the heat application is
completed (about a minute), the transfer paper is
removed and discarded. When the product cools down,
the sublimation dye is encapsulated within the surface
(instead of on top). The result is a high-resolution,
permanent coloration that won’t peel or crack. And in the
case of apparel, sublimation will not fade, even after
multiple washings.

19. Advantage of sublimation
Any image can be printed all over the fabric
The result of heat transfer printing and digital
printing using low sublimation disperse dyes would
be the same.
Colors can be extraordinarily brilliant due to the
bonding of the dye to the transparent fibers of the
synthetic fabric.
Truly continuous tones can be achieved that are
equivalent to photographs, without the use special
techniques such as half-screen printing.

21. Disadvantage of sublimation
•Back side of fabric always be white as it only prints the
surface of the textile.
•Sampling cost is high.
•Cost and lead time will be high for smaller run.
•Not success for light weight qualities like chiffon, ggt.
•If we stretch the fabric 20% or more then you lose a whole
stack of color depth when the white shows through the
fabric/knit ribs (dark blue suddenly becomes light blue, black
becomes grey).
•Sublimation heat transfer is suitable for polyester fabric only.
The limitation of sublimation is that it only works on polymer-
based surfaces,

23. Difference between Sublimation and
Digital Printing
Sublimation Printing
• Paper image is transfer on the surface of
the polyester fabric.
• There is no need of fabric to be coated.
• Base fabric should be synthetic or 100%
polyester,
• Disperse dyes are used
• Sublimation will not fade, even after
multiple washings
• Sublimation dyes does not penetrate the
surface of fabric. So back side of fabric
always white.
• Production feasible and less costly for
bigger run.
Digital Printing
• The inks are printed directly to the
coated fabric.
• There is need of fabric to be coated .
• All fabric can used as base except
polyester or synthetic.
• Reactive dyes are used
• Digital print can get fade after
multiple washing.
• In this dyes penetrate the surface of
base fabric. Digital relying on
molecular bonding,.
• It is not production feasible , Ideal for
sampling only.
