UV Lamps: Everything you wanted to know about

Ir. Sugeng Endarsiwi (Printing Ink Manufacture)   In order to find out more about UV and how it works, I went to an expert who has been working with UV technology for over 20 years, Norm Fitton, President of Anniversary UV. Most printers buy UV systems, which may be supplied by the manufacturer of the equipment but made by someone else. Understanding how UV lamps work can improve their performance and save you money. There are different types of UV lamps for different applications. Low-pressure UV lamps may be used for disinfecting purposes, curing nails and dental fillings, or water purification. The type of lamp used in printing applications is usually a medium-pressure, linear (straight tubes), mercury vapor arc lamp. Medium-pressure UV lamps cure inks and coatings instantly. It is a photochemical, not a heat process. It allows the equipment to run at very high speeds for extended periods. General-use light bulbs have a filament. The electricity causes the filament to glow, prod...

Site Acceptance Test (SAT): Acceptance Criteria, Environmental Conditions & Commissioning Readiness

-
  Ir. Sugeng Endarsiwi / Printing Ink Manufacture Site Acceptance Tests (SAT)  rigorously verifies that installed systems meet defined acceptance criteria, including functional, performance, and safety benchmarks, under precise environmental conditions like temperature and humidity. This careful testing confirms operational readiness and integration within actual facility environments, preventing issues during commissioning. By controlling and monitoring these conditions meticulously, the LotusWorks team ensure systems perform reliably in real-world scenarios. Exploring our approach further reveals how we guarantee seamless commissioning and system integrity. What is a Site Acceptance Test (SAT) and Why It Matters A Site Acceptance Test (SAT) verifies that installed systems perform according to specifications under actual environmental conditions before full operation begins. Commissioning plays a crucial role in coordinating these tests to ensure reliability and compliance a...

Raman spectroscopy

  Ir. Sugeng Endarsiwi ( Printing Ink Manufacturer ) What is Raman spectroscopy? Raman spectroscopy is a chemical analysis technique which involves illuminating a substance with a laser and analyzing the light that is scattered off the surface of the substance. The scattered light can provide a lot of information about the substance and its structure, and can be used to identify, characterize, and quantify many chemical components.  Light scattering explained When light is scattered off a sample there are two possible outcomes: (1) Elastic scattering , also known as Rayleigh scattering, occurs when the scattered light has the same energy as the light that initially struck the sample. This means that the elastically scattered light will be the same frequency, wavelength, and color as the original beam of light. (2)  Inelastic scattering, or  Raman scattering , occurs when the scattered light has a different energy than the light that initially struck the sample. This ...
