his guide provides a step-by-step process to determine the appropriate UV-LED curing equipment for your printing setup. Considering factors such as production process, efficiency, and equipment specifications. It includes a formula to calculate the required width of the UV-LED curing lamp based on energy requirements, conveyor belt speed, and lamp power.
First Of All: Assess Your Production Process
The first step is to identify the specifics of your existing production process, including:
- Type of printing equipment (e.g., flexographic or offset)
- Brand and model of the printing equipment
- Printing width
- Current printing effect
- Desired outcomes
Communicate with UV-LED Equipment Manufacturers
When consulting UV-LED equipment manufacturers, provide essential information such as:
- Required UV wavelength
Specify the UV wavelength required for your ink curing process.
- UV radiation energy for ink curing
Provide the UV radiation energy required to cure your specific ink.
- Desired production efficiency
Communicate your desired exposure time for efficient production.
- Area to be illuminated
Communicate your desired exposure time for efficient production.
Communicate with UV-LED Equipment Manufacturers
- Radiation Illumination
Production efficiency directly impacts the required radiation illumination (mW/cm²) of UV-LED curing equipment. Calculate the necessary irradiance based on the UV energy required for curing and desired exposure time.
- UV Energy Requirements
Consult your UV ink supplier for UV energy requirements and select the appropriate UV wavelength (e.g., 365nm or 395nm).
Calculate UV-LED Curing Lamp Width
Utilize the following formula to calculate the width of the UV-LED curing lamp:
- Width (L) = Q * V / W
Where:
- Q: Energy required for ink curing
- V: Conveyor belt speed
- W: Curing light source power
For example, if an ink requires 4000mJ for curing, and the UV LED curing lamp power is 10000mW/cm² with a conveyor belt speed of 0.1m/s, the calculated width of the UV LED curing lamp would be 40mm.
Consider Additional Factors
- Lamp Length
Generally, the length of the UV light source corresponds to the width of the conveyor belt.
- Equipment Stability
Consider leaving a margin for equipment stability and opt for slightly wider equipment or higher intensity options.
- Additional Requirements
UV-LED equipment manufacturers can provide a rough quotation based on these parameters, and additional requirements such as cooling options and control preferences can be discussed to tailor the solution to your needs.
