An Overview of Digital Textile Printing Technology
All over printing began its journey in our garment industry
from the eighty’s. Although initially curler printing technique become general,
later flatbed and rotary screen printing techniques received reputation.
Peoples tastes, preferences and wishes are changing with the alternate of era.
Especially today’s younger society is much greater privy to their dress and
style. Therefore, the call for for all over printing is growing day by day
everywhere in the global together with Bangladesh. There are many extra
merchandise inclusive of t-shirts, shirts, pants, 3-piece, mattress-sheets and
so forth wherein throughout print is getting used. However, there are several
limitations to the techniques of all over display printing, considered one of
which is – all styles of design can't be printed through using flatbed or
rotary screen printing method. All though it's miles feasible to print 1-20
colors by the ones methods, normally more than 12 colorings are not published,
the main motives are two: 1) Print value is excessive & 2) Machine
complexity. Also, the picture print and impact of 3-D can not be sincerely highlighted
through screen printing strategies. A new chapter has been delivered to the
printing industry to triumph over these kinds of various troubles, this is
Digital Textile Printing.
What is Digital Textile Printing?
Digital textile printing is a technique in which colorful
designs are embossed on an expansion of fabric the use of digital ink-jet
printing technology, i.E., any design can be without problems and accurately
printed on fabric. Digital fabric printing is one of the maximum promising
tendencies in the fabric industry. Maintaining the design satisfactory, digital
textile printing has opened the door to many possibilities to fulfill the
developing call for for textile printing. This printing approach does not
require any displays and there are no shade boundaries. Digital printing is
also the ideal generation for printing 3-d designs. Using this technique may be
revealed on fabrics, and also printed at once on clothes like t-shirt, shirt,
denims etc.
Digital Textile Printing in Bangladesh
Digital printing become first patented in 1968 and received
popularity in 1990. In 2015, Beximco Group used digital fabric printing machine
for the primary time in Bangladesh. At gift, there are nearly 20-22 factories
in Bangladesh like Square Group, Liz Group, Knit Concern, Padma Textiles,
Fortis Group, Mondol Group etc. That have digital textile printing machine.
About 60% of total digital prints are made in Bangladesh, India, Indonesia,
Pakistan & Vietnam. Today, Bangladesh has won the ability and capacity to
compete with any united states inside the world with All Over Printing (Screen
printing) and has created a sturdy role, but we are still a lot in the back of
in All Over Digital Printing.
Continuous Process Flowchart for Digital Textile Printing:
How is Digital Textile Printing Done?
Let’s check how digital textile printing works. A normal
technique waft has been explained beneath-
Design Development: The first undertaking for virtual
printing is to create a layout according to buyer’s necessities. A layout
developer/artist creates colorful layout with the help of graphic software like
Adobe Photoshop (someday Adobe Illustrator) and CYMK coloration model is used
as the primary colour. Designers generally used the TIFF files for printing, to
maintain the exceptional of paintings. If the design is unique, the
hand-performed artwork is scanned and transformed to digital layout, and of
route the design does no longer have firm borders to repeated usually. Now this
virtual picture can be transferred to the material.
Fabric Preparation: Before the printing procedure, we ought
to pre-treat the material with liquid (chemical) answers. Generally, cotton,
viscose fabrics are ink-jet printed with reactive dye. So that, during this
method thickener, alkali and urea are used that put together it to just accept
the dye/ink and higher absorb the coloration. Fabric preparation technique
allows to put off the cloth crushes and makes it stiffer for better feeding for
the duration of printing.
Ink Selection: Now the question is what form of ink may be
used? What types of ink is needed relies upon on what types of material we're
the use of. Some common forms of ink are discussed below-
Printers & Printing: Generally, digital textile printing
makes use of ink-jet generation and ink cartridges. The pretreated material is
then sent to a virtual printer, where the machine sprays ink/dye with tiny
droplets as ordered with the aid of the design and software. At first, the
cloth is set easily and with right anxiety to keep away from the pass over
prints. Then the heads of printing gadget are set consistent with the fabric
thickness and cloth width. So that, the greater system heads, the greater the
manufacturing. There are many types of digital printing gadget inclusive of-
Fixing: The very last step is solving. Fixing way the
permanency of the layout. It depends on the form of material and dyes. Fixation
is performed thru some of strategies relying at the cloth and printing method.
Washing: After dye/ink fixation the material is washed and
dried properly.

Faults of Digital Textile Printing with Remedies
Causes: In case of darkish shade printing, coloration
staining is seemed in the unprinted area.
Remedies: Fabric should now not come into the contact with
each different all through loop formation in steaming. Coating recipe need to
be suitable. Clearly do away with the excess colour.
Causes: Due to choppy singeing.
Remedies: Remove sticking out fibers from the fabric floor
properly before coating. Chemical tank should be clean.
Causes: Uneven singeing and mercerizing. Unsuitable coating
chemical.
Remedies: Singeing and mercerizing process ought to be
performed nicely earlier than coating and also the usage of appropriate coating
chemical.
Causes: Most essential hassle we are facing in virtual
textile printing is coloration variation. Printing the design flawlessly with
accurate shade however, after completing we get special colour. Due to incorrect
chemical coating and completing parameters color variant seems.
Remedies: Recipe of chemical coating need to be perfect and
hold the viscosity & pH of coating answer. During steaming, washing and
finishing, all the parameters need to be right.
Global Digital Textile Printing Market Size & Growth
There isn't any doubt that the global pandemic has brought
monetary crisis, however it has additionally supplied many new business
opportunities in the fabric enterprise. According to the article of Federation
of European Screen Printers Associations (FESPA), regardless of the global
COVID-19 crisis and the financial downturn, the digital fabric printing
marketplace worldwide will nevertheless develop to 7.7 billion rectangular
meters through 2027 at a CAGR of three.6% from 2021 to 2027.
In May 2020, Allied Market Research predicted that the
marketplace cost of global virtual fabric printing changed into US $2.2 billion
in 2019, to be able to growth to US $8.Eight billion by using 2027, at a CAGR
of nineteen.1% from 2020 to 2027. The growing call for for virtual era for
fabric printing and sustainable printing inside the garments & advertising
enterprise are expected to have a wonderful impact on production call for.
In July 2020, Research and Markets said that the worldwide
virtual fabric printing ink market length become US $1112.Zero million in 2019.

Opportunities of Digital Textile Printing in Bangladesh
Although Bangladesh did tremendous in All Over Printing
(Flatbed & Rotary Screen Printing), but Bangladesh remains some distance in
the back of in All Over Digital Printing. Lack of professional manpower,
application of terrible era, use of low-first-class raw substances are the main
motives for this situation. Also, we don't have any opportunity to learn about
virtual printing technology. This is why graduates and experienced technicians
can't enrich their expertise about virtual textile printing. Our essential
competitors like China, Pakistan, Turkey are advancing very fast in printing
industry. We want to take several steps to overcome those problems, which
include: AOP and Digital Textile Printing subjects to the educational
curriculum, so that you can give you primary thoughts from the very starting.
Those who're pretty proficient in theses topics can enter the industry with
realistic information if printing specialists and industry leaders collaborate
with the universities/faculties and arrange training for the students. As a end
result, our new technology can be capable of recognise about new technology and
innovations.
Digital fabric printing technology has opened the door to
creativity with the aid of encouraging photographic replica, growing detailed designs
and experimenting with modern-day applications. The enlargement of published
t-blouse zone involving the evolution of Direct-to-Garments (DTG) era is a
phenomenon that has grown swiftly. The modern-day market demonstrates a few new
innovations in virtual textile printing like non-stop inkjet,
electrophotography, thermal inkjet and so on., each generation having special
and specific traits, advantages and barriers. So, we ought to work harder with
