An Overview of Digital Textile Printing Technology
All over printing started its adventure in our garment
enterprise from the 80’s. Although to start with roller printing technique was
normal, later flatbed and rotary display screen printing strategies gained recognition.
Peoples tastes, options and needs are changing with the alternate of era.
Especially nowadays’s young society is a lot extra aware of their get dressed
and style. Therefore, the call for for all over printing is increasing each day
everywhere in the international which include Bangladesh. There are many extra
products which includes t-shirts, shirts, pants, 3-piece, bed-sheets and so on
where throughout print is getting used. However, there are numerous limitations
to the strategies of throughout display printing, one among which is – all
types of layout cannot be revealed with the aid of using flatbed or rotary
display screen printing method. All though it is viable to print 1-20 colorings
via those methods, typically more than 12 colours are not revealed, the primary
motives are : 1) Print cost is excessive & 2) Machine complexity. Also, the
image print and impact of 3-d can't be in reality highlighted via screen
printing techniques. A new bankruptcy has been brought to the printing enterprise
to triumph over all these various issues, that is Digital Textile Printing.
What is Digital Textile Printing?
Digital fabric printing is a way in which colorful designs
are embossed on a spread of fabrics the use of digital ink-jet printing era,
i.E., any design can be without difficulty and correctly printed on fabric.
Digital fabric printing is one of the most promising traits inside the fabric
industry. Maintaining the design excellent, virtual fabric printing has opened
the door to many opportunities to meet the growing demand for fabric printing.
This printing approach does now not require any monitors and there are not any
color barriers. Digital printing is also the ideal era for printing 3D designs.
Using this approach can be printed on fabrics, and additionally printed
directly on clothes like t-shirt, shirt, denims and many others.
Digital Textile Printing in Bangladesh
Digital printing became first patented in 1968 and received
recognition in 1990. In 2015, Beximco Group used virtual textile printing
device for the primary time in Bangladesh. At present, there are nearly 20-22
factories in Bangladesh like Rectangular Group, Liz Group, Knit Concern, Padma
Textiles, Fortis Group, Mondol Group etc. Which have digital fabric printing
machine. About 60% of overall virtual prints are made in Bangladesh, India,
Indonesia, Pakistan & Vietnam. Today, Bangladesh has won the skill and
capacity to compete with any u . S . A . In the world with All Over Printing
(Screen printing) and has fashioned a sturdy position, however we are
nonetheless so much behind in All Over Digital Printing.
Continuous Process Flowchart for Digital Textile Printing:
How is Digital Textile Printing Done?
Let’s check how virtual textile printing works. A regular
technique glide has been explained under-
Design Development: The first mission for digital printing
is to create a layout in line with consumer’s necessities. A layout
developer/artist creates colorful layout with the help of photo software like
Adobe Photoshop (sometime Adobe Illustrator) and CYMK coloration version is
used as the primary colour. Designers commonly used the TIFF documents for
printing, to maintain the excellent of art work. If the layout is unique, the
hand-executed artwork is scanned and changed to digital format, and of path the
layout does no longer have firm borders to repeated commonly. Now this digital
photograph may be transferred to the fabric.
Fabric Preparation: Before the printing system, we must
pre-deal with the fabric with liquid (chemical) solutions. Generally, cotton,
viscose fabric are ink-jet printed with reactive dye. So that, during this
approach thickener, alkali and urea are used that put together it to simply
accept the dye/ink and higher absorb the coloration. Fabric training manner
helps to do away with the material crushes and makes it stiffer for higher
feeding during printing.
Ink Selection: Now the query is what kind of ink can be
used? What sorts of ink is needed relies upon on what varieties of material
we're using. Some common types of ink are mentioned underneath-
Printers & Printing: Generally, virtual fabric printing
makes use of ink-jet era and ink cartridges. The pretreated fabric is then
despatched to a digital printer, wherein the gadget sprays ink/dye with tiny
droplets as ordered through the design and software. At first, the material is
about easily and with proper anxiety to avoid the miss prints. Then the heads
of printing system are set in step with the cloth thickness and fabric width.
So that, the more system heads, the extra the production. There are many types
of digital printing gadget together with-
Fixing: The final step is fixing. Fixing way the permanency
of the design. It depends at the kind of fabric and dyes. Fixation is
accomplished through a number of strategies depending on the cloth and printing
technique.
Washing: After dye/ink fascination the fabric is washed and
dried well.

Faults of Digital Textile Printing with Remedies
Causes: In case of darkish shade printing, shade staining is
regarded in the unprinted location.
Remedies: Fabric should now not come into the contact with
each different all through loop formation in steaming. Coating recipe should be
suitable. Clearly do away with the extra colour.
Causes: Due to uneven singeing.
Remedies: Remove sticking out fibers from the cloth floor
properly before coating. Chemical tank ought to be easy.
Causes: Uneven singeing and mercerizing. Unsuitable coating
chemical.
Remedies: Singeing and mercerizing procedure need to be
executed well before coating and additionally the use of appropriate coating
chemical.
Causes: Most important hassle we face in virtual fabric
printing is coloration version. Printing the design perfectly with accurate
shade but, after completing we get distinct shade. Due to unsuitable chemical
coating and finishing parameters color variant appears.
Remedies: Recipe of chemical coating need to be best and
keep the viscosity & pH of coating solution. During steaming, washing and
finishing, all of the parameters have to be right.
Global Digital Textile Printing Market Size & Growth
There isn't any doubt that the worldwide pandemic has added
economic disaster, however it has additionally provided many new commercial
opportunities inside the fabric industry. According to the item of Federation
of European Screen Printers Associations (FESPA), notwithstanding the worldwide
COVID-19 disaster and the financial downturn, the virtual fabric printing
market worldwide will still develop to 7.7 billion square meters via 2027 at a

Opportunities of Digital Textile Printing in Bangladesh
Although Bangladesh did extremely good in All Over Printing
(Flatbed & Rotary Screen Printing), but Bangladesh continues to be far in
the back of in All Over Digital Printing. Lack of professional manpower,
software of bad technology, use of low-quality uncooked substances are the
principle motives for this case. Also, we haven't any possibility to learn
about virtual printing era. This is why graduates and skilled technicians can
not enrich their information about digital textile printing. Our most important
competition like China, Pakistan, Turkey are advancing very speedy in printing
industry. We need to take numerous steps to triumph over these issues,
including: AOP and Digital Textile Printing topics to the educational
curriculum, that will provide you with fundamental thoughts from the very
beginning. Those who are fairly proficient in theses subjects can input the
enterprise with practical know-how if printing professionals and enterprise
leaders collaborate with the universities/faculties and arrange training for
the students. As a end result, our new generation will be able to recognise
about new technologies and improvements.
Digital textile printing generation has opened the door to
creativity by way of encouraging photographic replica, creating precise designs
and experimenting with brand new packages. The enlargement of printed t-shirt
quarter involving the evolution of Direct-to-Garments (DTG) era is a phenomenon
that has grown swiftly. The cutting-edge marketplace demonstrates a few new
innovations in virtual fabric printing like non-stop inkjet,
electrophotography, thermal inkjet and so on., each technology having distinct
and particular traits, advantages and boundaries. So, we have to work harder
with those latest technology and innovations, in order that we are able to
reign ultimate inside the digital textile printing quarter as nicely.
