Whether you are using a single or multi-lamp UV Flexo system, it is crucial that your UV lamps have a consistent UV intensity output. An uneven intensity distribution can lead to hot and cold spots in your curing, causing spoiled product.

LEARNING OBJECTIVE

4. https://www.stafix.eu/blog/different-uv-curing-methods-in-offset-
printing/
The sun is a source of the full spectrum of ultraviolet radiation, which is commonly subdivided into UV-A, UV-B and
UV-C. Wavelength, a fundamental descriptor of electromagnetic energy.
Typical UV light source emission wavelengths range from ultraviolet (UV-C: 100 to 280nm; UV-B: 280 to 315nm;
UV-A: 315 to 400nm) to visible light (400 to 700nm) and infrared (700 to 3000nm).

What is ultraviolet wavelength?

5. Benchmark / Uniformity
UV Lamp
Performing benchmarks :
to identify areas for improvement to get the UV Lamp better power and correct UV
Dosage to Cured ink on press.
Uniformity ;
1. a state or condition in which everything is regular, homogeneous, or unvarying.
2. lack of diversity or variation, sameness.
By assessing what proper UV Dosage after performance and take specific action as
well.

6. Jumlah Unit UV Lamp
• Unit Ink and Coating on
Printing Machine (Flexo)
• CMYK = 4 Units
• Spot Color 1,2,3 = 3 Units
• Coating Unit = 1 Unit
• Total = 8 Units

13. 4. Test on run press as proposed speed target
5. Collect the exposed label Fast-check and observe to UV Dosage Chart
(mJ/cm2)

14. UV Dosage Analyze
- Speed
- Each Unit
- etc
• Continue the process for
other UV Lamp in each
unit
• Examine the expose
label and analyze the
pattern
• Reflector clean
• New/Old Lamp

15. PERLENGKAPAN

17. Faktor yang mempengaruhi
Kerja UV Lamp
• Intensitas listrik Power supply (watt / inch) : 400 W/Inch , 500
W/Inch, etc
• Umur Lampu (1000 jam decreased power of dosage +/- 30%)
• Reflector (new, shiny, dirty, dusty, burned)
• Setting Lampu (conector
• Ideal Checking, Awal pasang dan setiap 1000 jam

18. UV Dosage Optimize
• Power Intensity : 200 W/cm
• 137 mJ/cm2
• 100 m/min
• Fakta hasil test :
• 75 m/m = 30 – 40 mJ/cm
• 50 m/m = 40 – 50 mJ/cm2
• 30 m/m = 70 – 80 mJ/m
