Faridabad-based SASG UV Solutions, offers LED UV systems, which can be customised as per machine size and specification. The company uses LED diode with multi-wavelength 385- and 395-nm, which help dry any kind of LED UV inks and varnishes. 

Beside UV LED system, SASG UV Solutions manufactures water-cooled UV system, anilox coating attachment, UV coating machine, UV dryer for printing industry, automobile industry and industrial chillers, among others.

In the new facility, the company has the capacity to manufacture 30 machines per months. This shows 30% rise from its previous productivity. 

The curing business
Saini says the company is seeing a great potential for UV LED in India as it saves power and it is environment-friendly. 

The SASG UV systems can be used for printing on paper, metPET, PET and PP as well as UV coating and hybrid coating on surface. It is available for processes like inline six-colour and coater and offline two-colour machine. 

Aimed at saving power and offering customers an eco-friendly option to conventional Mercury UV systems, the company is into LED UV business since 2017. 

“Our system consumes about 70 % less power than conventional Mercury UV system. Plus, it has a better life, is zero maintenance as well as heat-sensitive,” Anil Saini, SASG UV Solution, said.

“Basically, UV LED 65% has less heat compared to the Mercury system. In one word, our system is economic and safe.”
So far, the company has installed 80 LED UV systems in India and abroad. Some of its Indian customers include Prakash Industry, Kanpur; Ashoka Printers, Kanpur; Color India, Kanpur; Naveen

Saini says usually in the case of UV printing, printers face the problem like shut down, lack of 100% cure, lack of rubbing resistance, tape fail and nail fail. “But SASG LED UV system doesn’t have such kind of problems. 

He adds the USP of the SASG LED UV system includes multi-wavelengths and focusing lens at each diode. The life of diode is 25,000 working hours. “The beads are repairable and replaceable,” he adds, “All the beads are mounted on copper PCB and fixed at 260 degrees Celsius temperature.”

The components of the system include LED UV module, and controller synchronised with master press and chiller. 

Using LED UV
Saini says LED UV consumes 60% less power compared to Mercury UV and 30% less compared to HUV. At the same time, LED UV emits 65% less heat as compared to Mercury and HUV. Again, LED UV is zero maintenance and user-friendly.

A single SASG LED UV system can dry the four-colour inks at 12,000-sph. The company offers 10,000 working hours warranty depending on the conditions. 

Customer testimonial

We have installed SASG LED UV solutions in July 2018. Its LED UV solutions are functioning well and economical too. We have installed two LED UV lamps from SASG on our new Komori five colour 20x30-inch printing press. SASG provides best after-sales services whenever we require. We went for LED UV solutions because it reduces energy consumption which directly reduces our expenses on power and curing speed is much faster than conventional UV. Right now, we are using the LED UV solution for our requirements in packaging and commercial printing.

Direct-to-garment screen printing machine by Grafica Flextronica

Mumbai-based manufacturer of screen printing machines, Grafica Flextronica, demonstrated its six-colour, 10-pallet direct-to-garment textile screen printing machine along with its flatbed screen printing machines to print transfer stickers and labels during Gartex Texprocess held at Pragati Maidan, New Delhi from 10 to 12 August 2019. 

According to Bhargav Mistry of Grafica Flextronica, while India has to improve a lot in process and standardisation in printing techniques, printers in the garment industry only look towards automation, but do not really work on colour management. “This need improvement,” said Mistry. “Even basic screen-making is also not well organised and needs improvement.”

Explaining the scope of improvement within the textile printing industry, Mistry said, "While importance is given to printing machines, experience and knowledge on textile printing should be given equal importance." He offered a breakdown. “A textile printer should give 40% importance on designing, separation and colour management; 40% on screen-making; 10% on quality inks and 10% on machines and automation,” he said, adding, “However, in today's scenario, 99% importance is given to printing machines.”

Mistry said the main reason is lack of proper education and expertise. “In textile industry, especially in printing, there's a huge demand of skilled labour, but if you look the other way around, there is a huge shortage of skilled labour."

He explained, “If you go to printing factories, you will notice that they really need skilled manpower."

Commenting on the latest trends in textile printing, Mistry said, “Value addition and simplicity in printing is what I see new in textile printing.”
