Dear All,
Hope everybody is well and doing
great! At present I’m passing very busy time with my present JOB, that’s why since
last few months I have been unable to publish any new topics.
However, at-last today I’ve just sat
to write a new article for all of you. My today’s topic is based on a Modern
print technology. The name of this print technology is Dye Sublimation Print.
Dye
Sublimation Printing
Introduction: It is a totally new
technology for printing sector. It’s been the most modern technology in the
printing. It’s really a new experience for printing world. Many people
also called this print as thermal Dye Sublimation print.
Technical Details of Dye Sublimation
print:
Dye Sublimation print are not works like a normal screen print
or rotary print. In the normal printing process we put a layer of color on the
fabric or on the other printing surface. But the technology of Sublimation
prints totally different than normal print. The sublimation process dyes the
fibers of a garment, instead of putting a layer of ink on top of the fabric or
the specific surface. This different printing process has given the unique
advantage to the Dye Sublimation print. Dye Sublimation print,
are made from special sublimation dyes which penetrate synthetic materials (such
as Polyester) when we apply pressure and heat. During the transfer process, the
dye heats up and turn into a gas that bond with the synthetic portion of the
fabric. As in this printing process the dye makes a bond with the synthetic
fiber so it must be used with fabrics that have a high polyester content, at
least half of the total composition. That’s mean more synthetic in the fabric,
the better print quality. Dye Sublimation print
works based on CMYK technology. No print screen is needed for this print. We
make the design in the computer then directly transfer the design into the
printing machine.
Process of Dye Sublimation print:
Not only technical printing
process but also physical processes is different than normal screen print. There
are total two main steps. First step: Do the print on paper 2nd
step: Transfer the print from paper into fabric.
In normal screen print we put the
fabric cut panel on the table then put the ink/color layer on it. But in the Dye
Sublimation printing process at first we do the print on a
special typed paper by using the printing machine. Then we transfer the print
from paper onto fabric by using heat and pressure. The printing machine is like
as a big bubble jet printer. The printer head move from each side to another
during printing the paper same as the real printer. This printing machine has total
04 (four) different basic colors on it to make the print. After complete the print on paper we transfer
the print on the fabric by using a heat press machine.
Advantage of Dye Sublimation print:
As this printing technology the dyes
make a bond with the fiber so the image cannot crack, peel, or wear off. It
looks like a real one without any hand feel. This print is longer lasting than any
other prints. The image quality looks like new after several washings. Also remain
like a new one after many days uses. We can do this print within very short
time notice because this printing technology does not need any Film, Screen,
Scraper etc. There is no color making and mixing process, just separate the
color in a computer and send the command to the printer. The printer will do
all other things. As we don't need to lay the fabric on a print table so it consumes
very small places. We can easily set up a printing factory in a small, long floor
is not needed, this will help us to reduce the printing cost.
Disadvantage of Dye Sublimation print: This printing technology has some disadvantage
also. ……………..
