Early UV LED systems were not powerful enough to cure at conventional sheetfed and web offset print speeds, but technological advances have made it possible to deliver sufficient peak irradiance and energy density for most commercial printing applications — including digital inkjet, spot cure, and screen.water cooling uv led curing lamp In addition, new LED lamp designs and application-specific formulations make UV LED curing systems applicable for a much wider range of printing processes than previously possible.
A water cooling system is essential for UV LED curing systems that require high intensity, as it has a higher thermal conductivity and specific heat capacity than air. It can dissipate heat more effectively, helping to maintain consistent UV curing performance and extending the life of the LEDs. It is also critical to properly monitor the cooling system, as it can help identify potential problems before they cause unexpected downtime and loss of productivity.
