How to Choose the right UV LED Curing System for Printing Press?
This 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.

  • 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.
