How to Choose the Right UV Curing Lamp for Your Printing Machine?

Choosing the right UV curing lamp is essential for maintaining print quality, reducing downtime, and extending the life of your printing machine. With hundreds of lamp types available in the market, making the correct selection can feel overwhelming — especially if you're dealing with urgent production timelines. This guide will walk you through the key factors to consider when selecting a replacement or new UV lamp for your press.

1. Know Your Printing Machine Model

The first step is to identify the make and model of your printing machine. Most manufacturers design their UV curing systems to work with specific lamp specifications. Check your machine’s manual or nameplate for:

• Lamp part number (OEM code)

• Wattage and voltage requirements

• Lamp length (arc and total)

• Type of connector (e.g., ceramic, metal caps)
  
  

If your machine is a Komori, Heidelberg, KBA, or Ryobi, you can often find direct-fit compatible lamps without needing the expensive OEM version.

2. Match the Electrical Specifications

Choosing a UV lamp with incorrect wattage or voltage can result in poor curing or even damage to your system. Pay close attention to:

• Wattage per cm/inch (commonly 200–500 Watts/Inch)

• Operating current and voltage

Always consult your technician if you're unsure or you can call us and we can help you out with it.

3. Choose the Right Wavelength

Not all UV lamps emit the same wavelength. Different inks and coatings require different curing profiles:

Mercury (Hg). 365–370 nm wavelength For Standard UV curing

Iron-doped 380–420 nm wavelength For Thick coatings

Gallium-doped 400–450 nm wavelength. For Pigmented inks, varnishes

If you're switching to a new ink type or coating, your UV lamp may need to change too.

4. Consider the Build Quality

Cheap, low-quality lamps may seem like a bargain— but they often lead to:

• Shorter lifespan (less than 500 hours)

• Inconsistent curing

• Higher replacement frequency

Always go for Lamps that are made of High Quality Components. Lamps from reliable suppliers like UV Lamps India are manufactured to match OEM performance but at a better price point.
