LED Curing Solutions For Sheetfed Offset Printing:

AMS Spectral UV manufactures LED-UV curing systems for sheetfed offset printing presses, with ready-to-go solutions for 20", 30" and 40" presses, and custom/bespoke solutions for any other specified width of press.

We can readily retrofit UV LED curing systems onto presses from Akiyama, Heidelberg, KBA, Komori, Mitsubishi, manroland, Ryobi (RMGT), Sakurai and Shinohara, among others - we can also work with press manufacturers to equip your new press with our UV-LED curing technology.

THE PROCESS:

Prior to installation your press will be measured and its specifications confirmed via our engineering team, to ensure the curing equipment fits perfectly into your specific setup. A common system configuration consists of 1-2 LED lamps, typically mounted at the end of the press at an interdeck location pre-coater, or in the upsweep delivery location post-coater.

Our LED UV systems bring energy-efficient, heatless curing to sheetfed offset lithographic printing. Gone are powder-filled pressrooms, expensive IR/hot-air dryers, marking problems and waiting for sheets to dry. No other system provides the intensity, flexibility and fast return on investment that one finds with AMS Spectral UV’s family of LED-UV curing products. With simple installation on nearly any type of press, our goal is to help customers reinvent their conventional sheetfed offset printing operations to embrace the benefits of LED-UV curing, which include a higher quality end product digital turnaround speed.

UV-LED Curing For Flexible Packaging:

AMS Spectral UV manufactures UV-LED curing equipment for flexographic and label printing presses. We can readily retrofit or equip new presses from Bobst, Omet, and Mark Andy, among others. 

UV LED curing technology delivers deep consistent curing, top production speeds, heatless operation and high reliability with unprecedented uptime to tag, label and film producers. The ready availability of LED inks, including low-migration formulations, from major manufacturers has led to increased popularity of LED systems for packaging production.

For NARROW WEB:

AMS Spectral UV manufactures curing systems for narrow-web presses smaller than 17" (430mm) in printing width. These systems typically consist of 6 to 10 modules, stationed after every color application.

FOR MID- and WIDE-WEB:

We specialize in mid- and wide-web curing systems for flexographic presses, and offer seamless solutions that will not leave gaps or spaces in curing due to "daisy chain" style designs. 

 

LED Is The Solution For Flexo

Problem: Slower press speeds cause low production creating the need to add an extra shift or an additional press.
Solution: LED UV increases press speeds – one Flexo printer experienced an increase from 350 to 650 ft./min.

Problem: Lack of assurance of cure causing offsetting with standard UV.
Solution: UV bulbs burn out from the ends - therefore, the center of the substrate might be cured, but the ends remain tacky – causing offsetting and blocking. This is not a problem with LED UV.

Problem: Press downtime caused from standard UV faults.
Solution: LED UV does not have any moving mechanical parts (shutters) that cause press downtime. 

Problem: High energy bills from use of standard UV system.
Solution: LED UV uses as much as 65% less energy.

Problem: Standard UV burns through substrate causing significant downtime and the need to re-web the press.
Solution: LED UV doesn’t generate heat to the substrate. Plus thinner, less expensive film can be used.

Problem: Standard UV requires long start-up and cool-down wait times.
Solution: LED UV is instant on and instant off. No warm-up or cool-down time required.

Problem: Standard UV needs to be exhausted – heated/cooled air is wasted. 
Solution: LED UV does not require exhaust venting.

Problem: Standard UV bulbs contain mercury – a listed hazardous material. 
Solution: LED UV is a ‘green technology’ and does not contain Mercury or any other hazardous materials. 

Problem: Standard UV systems require ongoing operational maintenance.
Solution: LED requires no ongoing operational maintenance.

Problem: Standard UV bulbs burn out every 1,000 to 1,500 hours and are costly to replace.
Solution: LEDs last for more than 30,000 print hours (approximately 15 years).

LED Curing For Printing On Corrugated Material:

LED-UV curing systems can be used to secure inks and coatings onto corrugated materials, including plastic and cardboard based stocks. Using LED instead of UV or IR systems improves safety because LED curing is a low-temperature process, and removes heat from the press or other piece of converting equipment.

FOR CONVERTERS:

One benefit of our curing systems is they can be built to very wide widths, up to 4 meters. This enables them to be ideal for use on specialty equipment an in unique setups.

UV LED For Web Offset Printing:

AMS Spectral UV manufactures LED-UV curing systems of offset web printing, and can equip presses from Goss, Manroland, KBA, Komori and others.

Our equipment helps deliver sheetfed quality with web offset printing, and offers a host of environmental benefits over printing with IR and conventional UV systems. 

Printers also can eliminate browning, curling, wave formation and other common offset web printing issues with the use of LED-UV.

Presses equipped with LED-UV systems can operate at speeds of 40,000 impressions per hour, based on the performance seen by our current customers. 

LED-UV FOR Flexo CI Presses:

We can build systems for large-format CI (central impression) flexo presses, including those made by Uteco, SOMA, Bobst, KBA Flexotechnica, Comexi, and others. Because AMS Spectral UV specializes in seamless, wide-format curing systems, we have the experience and know-how necessary to work with the biggest CI presses in the world. Our curing systems can be used to produce food-safe packaging with low-migration LED inks.
 

Some of the other benefits of LED-UV curing for CI presses include:
1. Reduce greenhouse gas emissions
2. Eliminate VOC emissions
3. Offer an ozone-free printing process
4. Enable presses to run at double the speed with better curing results
5. Minimal heat on the press
6. Instant on/off capability
7. No incinerators needed
8. Sustainable and eco-friendly process
