UV Curing for Wide-Web Production
Wide-web production introduces different demands than narrow- or mid-web curing.
The curing system must deliver controlled UV energy across a substantially larger working width while supporting the line speed, substrate and chemistry requirements of the process.
RADMAX is designed around those conditions, with configurations extending to approximately 118.1 inches / 3000 mm and power levels selected around the required width.
For packaging, converting and other wide-web applications, Prime can configure the system around:
production width
UV chemistry
substrate
line speed
lamp chemistry
reflector geometry
cooling requirements
power control
machine controls
energy-delivery monitoring
Key Outcomes
Support curing widths up to approximately 3 meters.
Configure UV output around production width.
Select lamp chemistry around the curing process.
Choose reflector configurations around substrate and UV-delivery requirements.
Adjust system power in stepped or 1% increments.
Use closed-loop energy control where consistent UV delivery is required.
Add filtration, nitrogen inerting or chilled-web components where needed.
Support remote maintenance and controls troubleshooting.
Application-Engineered UV Curing
RADMAX configuration starts with the application.
Prime evaluates the press or converting line, chemistry, substrate, web width, production speed, available footprint and controls architecture before recommending a system configuration.
That application review can influence:
curing width
lamp type
power level
reflector selection
power driver
air handling
filtration
CED controls
nitrogen inerting
chilled roller or plate requirements
PLC integration
The result is a curing system configured around how the line actually operates.
Power Configured Around Web Width
UV Output for Wide-Web Applications
RADMAX supports different maximum power levels based on curing width:
Up to 78.7 in. / 2000 mm — 600 W/in
Up to 118.1 in. / 3000 mm — 400 W/in
This allows Prime to configure UV output around the required production width rather than treating every installation as the same lamp system scaled longer.
Built for High-Speed Web Applications
UV Curing at Production Speeds Up to 2,800 fpm
RADMAX is specified for UV cure speeds up to approximately 2,800 fpm / 850 mpm.
Actual operating speed depends on the application, including:
UV chemistry
substrate
lamp configuration
web width
UV dose requirement
reflector selection
number of lamps
This is the better way to use the 2,800-fpm number.
Closed-Loop Constant Energy Delivery
Maintain UV Energy as Production Conditions Change
RADMAX can be configured with Prime’s Constant Energy Delivery (CED) control system.
CED uses closed-loop control to manage UV energy delivery during production, helping the system maintain the required UV output as operating conditions change.
For high-speed and wide-web processes, this provides a more controlled approach than relying only on fixed lamp settings.
CED Control Option
Closed-loop control for constant UV energy delivery.
Multiple UV Lamp Chemistries
Match Lamp Output to the Chemistry
RADMAX can be configured with multiple UV lamp chemistries, including:
Medium-pressure mercury
Iron additive
Gallium additive
Different UV chemistries and coatings respond to different spectral outputs, so lamp selection should be considered alongside substrate, speed and process requirements.
Prime’s application team can evaluate those variables when specifying the system.
Reflector Options for Wide-Web Curing
Configure UV Delivery Around the Substrate
RADMAX supports multiple reflector configurations:
Optimum Reflectivity
Highest Reflectivity
Dichroic
Reflector selection affects how UV energy is directed toward the substrate and how thermal energy is managed within the curing process.
For heat-sensitive materials or wide-web applications, reflector selection becomes part of the overall system design rather than a standalone component choice.
Positive-Pressure Air Filtration
Help Reduce Airborne Contamination Around the UV System
RADMAX can be equipped with Prime’s Positive Pressure Air Filtration System.
The system supplies filtered air around the UV cassette to help limit airborne contaminants entering the lamp and reflector area.
For packaging, converting and other high-volume web environments where paper dust, coating residue or production debris may be present, filtration can help maintain cleaner operating conditions around the curing equipment.
Adjustable Power Control
Match UV Output to the Job
RADMAX supports either:
4/6/8-step power adjustment
1% power adjustment
depending on system configuration.
That allows operators to tune UV output around changes in:
line speed
substrate
ink or coating chemistry
job requirements
Controls and Remote Support
Integrate RADMAX With the Production Line
RADMAX uses a standard Beckhoff PLC with Prime Premier HMI options in 7-inch and 16-inch formats.
Alternative PLC platforms, including Siemens and Allen-Bradley, are available where required for existing plant or OEM controls.
Remote maintenance access can also be enabled, allowing Prime technical personnel to review operating conditions and assist with troubleshooting.
Remote Access Available
Remote system access can support troubleshooting and technical review without requiring every service interaction to begin onsite.
Where RADMAX Fits
Applications
-
UV arc-lamp curing for packaging lines where web width, production speed and UV dose requirements demand a large-format curing system.
-
RADMAX can be configured for converting applications where wide-web substrates, coatings and production speeds require application-specific UV system design.
-
Applicable to newspaper, magazine, direct-mail and book-production environments using compatible UV-curable inks and coatings.
-
RADMAX can also be evaluated for industrial processes requiring UV curing across wide substrates or continuous production lines.
-
Applications with large web widths, demanding process speeds or specialized coatings can be evaluated through Prime’s application-engineering process.
