The :Jeti 3348 UV Galaxy RTR utilizes 48 Spectra heads and
environmentally friendly UV curable inks to produce the fastest
output of any UV roll to roll grand-format printer on the market
today. The fl exibility of printing in 6 colors with true 600 dpi
resolution gives the :Jeti 3348 UV Galaxy the highest quality
of any printer in its class achieving 862 sqft/hr (80 m2/hr) in
the production billboard mode. A take-up unit is built into the
printer allowing the machine to be run by a single operator.
Now Knit RMG (Ready made garment) is the highest foreign currency earning sector of Bangladesh. For knit fabric processing its involves many chemical process, so drying is an important operation. The production of various mechanical finishes on knitted fabric involve conditioning of the material to a certain moisture content and then drying by different means.
The process of reproducing digital images on physical surfaces is called Digital Printing. The physical surfaces can be in any form like a common paper, cloth, plastic, a photographic paper, film, etc.
UV LEDs - Technology, Manufacturing and Application Trends 2016 Report by Yol...Yole Developpement
Â
After fast adoption of UVA LEDs for curing applications, UVC LEDs for purification/disinfection are now ready
FOLLOWING THE UV CURING BOOM, DISINFECTION AND PURIFICATION APPLICATIONS ARE FINALLY READY TO TAKE OFF
The UVC LED industry is still small but strong growth is expected in the next 18 months due to dramatic price reductions. In 2016 prices are 1/8-1/10 of what they were in 2015. This has been triggered by the industry’s development, its transition to mass production and improved device performance. With most of the industry believing that $1-$4/mW is the price that would trigger mass market adoption we are getting close to a UVC LED market boom. Another positive sign is that most UVC LED manufacturers are now focusing on developing cost-effective solutions rather than improving device power output. In parallel, the UVC LED industry continues to work on increasing lifetime and developing lower wavelength devices, below 280nm.
UVA LEDs continue to progress in the UV curing space. Continuous improvement of device performance coupled with price reduction has allowed the technology to be increasingly adopted in UV curing applications. Penetration of UV LEDs is increasing but we observe differences in adoption rates depending on application. Small size and low speed applications like spot adhesive and digital inkjets have the highest adoption rate, and most new developments use UV LEDs. This is due to the small module size and low irradiance level needed that limits the extra cost of integrating UV LEDs compared to the total price of systems like inkjet printers. On the other hand, applications that need high speed processes and/or high levels of irradiance such as screen printing or coating applications have lower adoption rates. This is because UV LED performance is not yet good enough to fully replace traditional mercury lamps.
In this context, we expect the UVC LED market to strongly grow from $7M in 2015 to $610M by 2021. Despite increased penetration rate in all applications, the UVA LED market will grow more slowly, from $107M in 2015 to $357M by 2021, moderated by price pressure.
The report presents a comprehensive review of all UV light applications including analysis of UV curing, UV purification/disinfection and analytical instruments. It highlights the UV LED working principle, market structure, UV LED market drivers and associated challenges, recent trends, new applications created by UV LEDs, UV LED market size split by application, and much more.

Changing The Game: Inkjet Textile Decoration and FinishingXennia Technology
Â
Xennia's Dr Alan Hudd discusses the market requirements for digital textiles, outlining the application drivers and challenges that need to be overcome, recognising the technology requirements for a complete production inkjet solution and finally, looks at digital finishing as a transformational technology. The talk was presented at IMI's 4th Annual Digital Printing Presses Conference in Florida, USA, June 2011.
The :Jeti 3348 UV Jetspeed is now available in a 4 Color
confi guration, featuring 48 Spectra print heads.
Capable of printing fast high quality images at speeds of
2500 sqft/hr (232 m2/hr) in production billboard mode at 300 dpi,
which is perfect for outdoor application.
The JetSpeed XL uses the latest in digital print technology
to enhance and utilize every inch of this grand format digital
printer for fi rst class production output. The JetSpeed XL
features 48 Spectra 80 picoliter print heads and prints in
4 colors at 300 dpi, specifi cally designed to print at production
high speeds of up to 5000 sqft/hr (465 m2/hr) in billboard mode.
This talk by Clive Ayling, Managing Director, Meteor Inkjet Ltd, at the IMI InPrint USA conference, April 2017, highlights the key considerations in making the most important design decision for ink jet printing systems - printhead selection. Printheads are the highest cost system component and printer performance and output quality are dependent on printhead characteristics and specifications.
Learn the key parameters and methodology to make an informed printhead selection decision for your industrial ink jet system.
Sending print data directIy to the printhead electronics makes it possible to achieve blistering speeds even with variable data when every item is different. Can you maintain optimum quality too? The benefit is significantly improved productivity because you can keep presses running with no waiting time. At TheIJC, DĂĽsseldorf, October 2019, Tom Mooney discusses recent technical breakthroughs and describes how the answer lies in a software engine that can obtain blistering speeds by driving data directly to the electronics whilst correcting for common quality defects.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:

Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

Single sided coating, material held away from skin contact
58. DIGITAL DYEING
Approach
Methods developed to use “difficult” aggressive dyes (VAT dyes)
Not usually used in “printing” but give higher end user performance
Benefits
Environmentally friendly, efficient use of natural resources
Very high fixation, with low discharge of unfixed dye
Low water and energy usage compared to traditional dye baths
Consistency of product quality
Consistent quantity of dye is laid down
Does not rely on pick-up of dye from dye bath
Different colour possible on each side of the textile
59. OTHER OPPORTUNITIES
Hydrophobic
Comfort of cotton material on skin side
Water and dirt repellent function on outside
UV/EB cured coatings
More rapid, compact in-line processing
More energy efficient than thermal curing
Antimicrobial
New functional materials possible to create effect
Selective deposition, efficient usage
Single sided, patterned to required areas
60. CONCLUSIONS
Inkjet technology will transform the textile industry
Higher productivity/lower cost
Higher flexibility
Allow economical shorter runs
(Mass) Customisation
Faster product design introductions
Higher quality
New functionality
Environmental benefits
Digital decoration and finishing enables process automation
Extensive R&D effort is needed for adoption
Will strengthen the competitive power of the Western textile industry
