UV Light technology

There are a few technologies and methods to produce artificial UV light, the main purpose of this light radiation is to be used for UV Curing, which is a high speed curing process in which high intensity ultraviolet light is used to create a photochemical reaction that instantly cures or bonds inks, adhesives, resins, coatings and other materials.

The main advantage of curing with UV-light is the speed at which materials or products can be processed, this advantage is especially important since the positive effect it has on production costs, by helping reduce productions times, thus helping increase productivity and reduce costs. Decreasing the curing or drying step time in a process can help reduce flaws and errors, mainly reducing the time that an ink or coating spends wet, which is one of the most critical steps and the most likely to produce errors. This can increase the quality of a finished item, and potentially allow for greater consistency.

Types of UV radiation

Ultraviolet light is a particular portion of the light spectrum, there are different types of UV wavelengths and they have specific applications, commonly the most used ultraviolet radiation (UVR) is categorized from 200nm to 400nm for UV A, B and C; UVR can be more widely defined as light radiation between 10 and 400 nanometers as specified by a more comprehensive subdivision by the ISO Standard ISO-21348, in which the UV wavelength is categorized in 9 different ranges.

Different Types of light radiation, including the visible spectrum. (spacenvironment.net)

  • UVC is a lesser energetic UVR used for top surface curing that creates surface hardness and abrasion resistance
  • UVB is a medium energetic UVR capable of deep penetration curing that creates coating and adhesive toughness
  • UVA is a more energetic UVR used to cure the deepest layers
  • EUV or extreme UV, has a wavelength between 10 and 120nm, which is considered as ionizing radiation.
  • Types of UV curing lamps

    There are two general types of UV lamps available, broad-spectrum metal arc UV lamps and LED-based UV curing lamps. In contrast, LED UV curing lamps have a consistent output, no bulbs to replace and no warm-up time, among other advantages.

    The standard broad-spectrum metal UV lamp has been the norm within the industry for many years, and several sub-categories exist for specific applications.

    LED-based UV lamps will have a quite narrow spectral output based around a single wavelength e.g., 280nm, 365nm, 385nm, 395nm, and higher.

    High Pressure UV Curing lamps (HP-UV) (also known as Metal Halide lamps), typical HP-UV curing lamps (Mercury) have short wavelength outputs that peak at 254nm and 365nm. A basic mercury HP-UV lamp will emit energy in both these ranges, but its strongest emission is in the short wavelengths.

    To alter the spectral output and access these additional radiation peaks – additive lamps are created by dosing the lamps with heavy metal compounds, this is called “doping”. Commonly used additives for HP-UV curing lamps are Gallium- doping (400 -450 nm) and Iron-doping (350 – 400 nm). Other additives are available dependent on the specific application.

    HP-UV curing lamps are normally manufactured from high-clarity, vitreous silica, quartz crystal. (skrmengineerings.com)

    Vacuum-sealed medium pressure UV lamps (MP-UV or MP-HO) lamps are mainly manufactured for disinfection applications. MP-UV lamps are used in a variety of applications from curing (UVA) to microbial disinfection (UVC).

    MP-UV lamps are made from high-quality quartz crystal, hermetically sealed using molybdenum foil within the hard quartz capillary, later pure tungsten pin electrodes are added with an over-wind of throated tungsten, each lamp is pumped and filled with an inert Argon gas in a precise process ensuring total accuracy of fill pressure and mercury content. The lamp is then completed by the use of either a metal or ceramic base and suitable electrical termination.

    MP-UV lamps are generally used for water or air disinfection (vgepro.com)

    Low Pressure UVC Amalgam Curing lamps (LPA-UV lamps) are perfectly suited for curing cationic based inks, cationic inks are generally an epoxy based resin that is cured by UV lamps. The wavelength of UV radiation is required to stimulate the photo initiator. The cure rate for these inks depend upon the specific ink’s formulation, light source and initiator contents.

    High-efficiency low-pressure mercury lamps offer 30% to 60% higher output at a spectral output of 254 nm and do not emit ozone. (heraeus.com).

    UV Light-emitting diodes (LEDs) can be manufactured to emit radiation in a specific wavelength range. LED UV curing lamps offer many advantages over conventional UV curing systems including long-life, cool temperature cures, no warm up times, constant intensity and reduced power consumption.

    Curing equipment based on LEDs can achieve uniform frequency and intensity output for consistent cures, facilitating superior process control, increased manufacturing throughput and lower operating costs. LED UV light curing offers several significant advantages over conventional arc UV sources, however LED UV curing lamps feature narrower wavelength spectrum emission than that of conventional equipment, so non-standard or special wavelength requirements may not be cheap to manufacture or sometimes even possible to find.

    LEDs are cheaper than mercury bulbs, lasting for several years and consuming less power (flaar archive)

    By having a clear understanding of the UV curing process and the technology already available, manufacturers can make educated selections to optimize their process.

    The majority of UV curing inks begin curing when exposed to the correct light, and will stop if the light is removed, so it is important to ensure a full cure is achieved in the exposure process.

    UV lamps can be specifically matched to special or "non-standard" inks or coatings with different photoinitiator sensitivities and activation wavelengths such as UV LED inks.

    If you thinking of purchasing a UV-curable inkjet printer, you might like to know what kind of technology is inside.

    Digital printers, screen printers, offset press commercial printers, sign shops, and photo labs primarily want to produce images that satisfy their clients and thereby bring in a profit for everyone concerned. So the results of the printing are what count. It is rare that a print shop owner or manager has time to learn what is going on inside the machine, other than the obvious need to know enough to properly operate the printer.

    But all kinds of interesting technology are inside a UV-curable flatbed printer. If you are seriously thinking of purchasing a UV-curable inkjet printer it is expected that you will visit trade shows and a manufacturer’s or distributor’s demo centers too. Before you make your actual purchase it is essential that you visit companies that have UV-curable inkjet printers at work.

    So let’s look at a UV-curable printer from the point of view of what an end-user, who is thinking of buying this printer, needs to know.

    efi VUTEk 3r UV printer. Photo: FLAAR-REPORTS archive.

    What features and factors to look for when making your Short List of brands and models to consider buying

    Printheads as one factor of Print Quality

    There are subtle differences between some printheads; dramatic differences among others. So a printhead is a crucial component in a UV printer.

    If you are a print shop owner, manager, or operator, it definitely helps to know the pros and cons of the printheads that are inside the printer(s) on your short list. You do not need to know whether it is a side-shooter or top-shooter or shared-wall (leave that to the engineers). What you need to know is how robust they are, how often will they fail, how long does it take to replace them, how long the warranty is.

    efi VUTEk 3r printhead alignment. Photo: FLAAR-REPORTS archive.

    What part of the Printer System Moves?

    When you visit a major trade show you may notice that the relationship between the positions of the printhead and the media vary. There is no one single technology of media-feed that has become de-facto standard. Each printer integrator has done their best to maximize the benefits of whatever feeding mechanism they have decided on. There is no one system, which is perfect, and no system (so far), which has enough serious downsides so as to suggest that you should always avoid it.

    Holding stationary materials or transporting moving substrates impacts on image quality. In a regular solvent or aqueous printer the printheads go back and forth on the X axis. The media is transported incrementally by being pushed or pulled along the Y axis. Most of these printers have optional settings for bi-directional printing (faster) or uni-directional printing (tends to be higher quality, but slower).

    Anatomy of the flatbed feeding and take-up system

    When you print with a water-based or solvent ink printer, the media or substrates are made for feeding through such a printer. The solvent printer manufactures know more or less what kinds of materials will be fed through their printers, so they can arrange the pinch rollers and all the rest of the feeding system to accommodate these materials.

    But with a UV flatbed, people may run ceramic tiles, glass, or wooden doors through the printer. The manufacturer can’t be expected to design a special feeding system for each coefficient of friction of the surfaces of these often radically diverse materials. So some materials feed better than others

    But even once the material is printed, it has to move all the way through the system and out the other end. A 9-foot length of wood, Styrene, Sintra, foamcore or whatever needs somewhere to go. This somewhere is the take-up table.

    How is the Material Held Flat?

    There are several ways to hold rigid material flat:

    • A vacuum table
    • Pinch rollers

    Pinch rollers are as much for feeding the material as they are for holding it flat. Pinch rollers usually work in unison with a grit roller. The pinch roller is on top; the grit roller is at the bottom. But there are many variations and size differences of these roller systems.

    Vacuum tables can be very expensive, as in five to fifteen thousand dollars, or more, depending on size. Vacuum tables are not as effective as you might wish; a vacuum table can keep a piece of foam-core from sliding, but a vacuum table can’t hold a warped foam-core totally flat. In other words, a vacuum table does not suck most materials totally flat; at best it holds them relatively flat, and keeps them from sliding around.

    UV-cured Ink

    UV-curable ink has been used for many years in the screen printing industry. But getting the ink to jet through a piezo printhead, accommodating the speed, and a host of other factors, was not easy.

    When hit by UV radiation, UV-curable ink becomes a solid instantly. Once it is no longer a liquid, it can’t enter the pores of the material. Since the material usually is solid, and has no ink receptor layer, the ink stays on top of the material. Indeed you can run your fingers over the image and feel the ink.

    LED and Mercury Arc Lamp on the field

    Production expectations as much as the technology dictate the uptake of LED and the speed with which it replaces Mercury Arc curing.

    But its just a matter of time before LED technology can match Mercury Arc curing’s performance. When it reaches that point it will cease to be viable, but that point is still on a far horizon.

    Mercury Arc lamps are ideal light sources for applications that require high intensity spectral lines emitted in the deep UV to visible light regions. Their unique UV emission spectra make them popular for unique applications that need enhanced UV output such as UV spectroscopy, UV curing and other industrial processes, and environmental and medical applications.

    LEDs are based on semiconductor technology. Specific wavelengths are directly emitted by the current input. The spectrum is a quasi-monochromatic radiation in defined wavelengths, e.g. 365nm, 385nm or 405nm.

    Protecting against Static Electricity

    When the material receives a static charge then the entire surface of the printer attracts ink. The ink is drawn to the entire surface of the material, even outside the area of the intended design.

    Static charge will be worse in dry environments (such as during winter with central heating), or in an area with rugs, or if the material itself comes with static charge because it is rubbed (while cleaning, for example).

    To protect against build-up of static charges on the material most printers are grounded and some printers have static bars.


    Every aspect of UV-curable ink printers has advanced in the last years. Ink formulations and printhead engineering are leading the way. In other words, the ink used today is dramatically better than the ink first offered in 2001 and 2002. Manufacturers now see a growing market for their products and are willing to devote R&D dollars to make products tailored for the needs of inkjet printers, such as smaller size, drastically lower prices, and less heat emission.

    Traditionally, UV inkjet printing on clear vessels requires a stuffing agent known as a “foxtail” to block the UV light from curing the ink and damaging the print heads. Recently Inkcups introduces a new feature for Helix digital cylinder printers: Transparent Pin Curing.

    Transparent Pin Curing (TPC) is a specialized system that enables UV inkjet printing on clear products such as plastic bottles, glassware, spirit, and wine bottles without the need to add a UV-blocking agent into the vessel. With this new patent-pending technology, containers remain uncontaminated and sterile on the inside and print head life is protected. As an added benefit, removal of this extra step thanks to the TPC system also streamlines the production process.

    The TPC system is available as a field-upgradable retrofit for existing Helix printers or on new Helix machines. These include the Helix Digital Cylinder Printer and Helix Hi-Fi Photorealistic Rotary UV Printer.

    “We have been developing and testing this new feature for some time and are excited to bring it to market. The revolutionary transparent pin curing system will simplify production, improve efficiency and is completely retrofittable to our fleet of Helix® Digital Cylinder printers. It makes a significant difference for transparent items,” Ben Adner, CEO of Inkcups.

    There are tons of UV curing applications, its constant innovation has led to consider that UV curing is one of the most versatile market in the world, this without mentioning that its characteristics provide multiple advantages and great results over many different materials.

    Faster production and lower costs are some of the most common challenges for automotive manufacturers and suppliers face.

    UV Curing is a great potential solution when it comes to industrial coatings and to transform automotive parts and body manufacturing.

    Here are some of the many benefits of using UV Curing coatings instead of heat:

  • Reduce floor space and utility costs, UV Curing doesn’t require large ovens to execute the process.
  • Coating process time. UV-cured coatings can take a few seconds to cure, so there is no comparison with the 30 minutes baking cycles. This also helps reducing sag, dirt defects and oven cleaning processes.
  • Reducing volatile organic compounds (VOCs) which can be harmful chemicals. UV curing operations ranges from 0-15%, while traditional baking processes ranges from 40-60%.
  • Improving resistance to scratch and marks.
  • Durability and resistance to chemical degradation.
  • The filter effect of UV absorbers protects the substrate against color change and photochemical degradation, which can lead to delamination.

    UV-Degradation in Plastics

    Some plastics can be susceptible to damage when they come into contact with Ultraviolet (UV) rays for a prolonged time, leading to cracks or color fading and even the disintegration of the plastic. This raises the question; Which plastics are UV stable or can withstand UV exposure better?

    Ultraviolet radiation consists of photons with high energy relative to visible light, this radiation is split into three types, these are UV-A, UV-B and UV-C.

    UV-A has a wavelength range of 400-320 nm, while UV-B has a range of 320-280 nm. Meanwhile, UV-C’s range stands at around 280-200 nm.

    UV-C is not present in our perceived sunlight, because wavelengths lower than 300 nm are absorbed by the ozone layer in the upper atmosphere, the general effect of UV-C is killing bacteria and microorganisms by disrupting their DNA, so we can focus on UV-A and UV-B.

    UV effects on different types of plastics

    UV energy can excite photons, when absorbed by plastics, in turn, can create free radicals. This is the beginning of degradation. As a matter of fact, several pure plastics simply cannot absorb UV radiation.

    The most common ways you can detect if a plastic is being affected BY UV are:

  • You may notice a pale appearance or color fading on the surface of the material
  • The plastic’s surface becomes brittle or cracked

  • UV-Degradation-in-Plastics

    Notable color fading in exposed to sunlight (UV radiation) Nylon rope. (quora.com)

    The most widespread UV damage mechanism in plastics is called chain scission by photolysis, this is the breaking of long chain polymers into shorter ones. This almost always results in a degradation of physical properties such as strength or degradation of visual properties such as color and texture.

    UV resistant plastics

    Some polymers are more stable to UV exposure than others, there is a class of high-performance polymers called fluoropolymers that exhibit excellent UV resistance. Teflon has become a genericized name for all fluoropolymers. fluoropolymers are exceptionally resistant to UV degradation. Accordingly, PTFE or FEP are almost always used for wire insulation on UV lamps or in UV equipment.

    Here is a short list of them:

  • Polyethylene
  • Polytetrafluoroethylene (PTFE)
  • Fluorinated ethylene-propylene (FEP)
  • Polyvinylidene fluoride (PVDF)

  • UV-Degradation-in-Plastics

    With their high performance against UV come high prices, fluoropolymers are among the most expensive polymers.

    UV coatings and other protection

    UV protective curable coatings are composed of acrylate functionalized resins, which polymerize or cure instantaneously upon exposure to UV light, thereby being easy to apply and efficient. Energy-curable resins can be 100% solids materials or can be diluted with solvents for ease of application, since coatings on plastic parts are mostly spray-applied, solvents are used to reduce viscosity.

    In terms of the components more likely to be at risk of UV damage, automotive parts are high on the list. The effects will predominantly result in a change of the material’s surface layer – and some plastics, if damaged by UV, will ultimately lead to the component failing altogether.

    The best coatings are multi-layer systems. The coating of plastics begin with the application of a primer, which has a binding effect on the basecoat, that is then applied over the primer. Finally, a clear-coat containing the light stabilizers for UV protection seals the coating system protecting the plastic.

    Fighting COVID-19 using UV

    In light of the new COVID-19 spread (pun intended) scientists are not only looking for a cure but also ways to prevent the virus form spreading.

    So far we know that alcohol can eliminate COVID-19 from surfaces and that antibacterial soap is also a great way to disinfect.

    People are now speculating UV lights can kill the COVID-19 virus, but are they really effective? Even US President Donald Trump suggested using strong UV light to treat COVID-19 Patients. But that won't prevent or treat any cases of the disease, since UV lights can cause skin cancer.

    The premise is not completely wrong or incorrect. For decades, scientists have known about the disinfection ability of ultraviolet wavelengths, specifically germicidal UV (also known as UV-C). This is where the main difference relies; regular UV lights are not the way to go, but what about UV-C?

    What is the difference between UV and UV-C?

    Let´s start from the beginning, sunlight contains three types of UV: UV-A, UV-B and UV-C.

  • UV-A, which constitutes the majority of the ultraviolet radiation that, reaches the Earth´s surface and can penetrate the skin deeply, cause skin-aging, wrinkles and age spots.
  • UV-B can damage the DNA of the skin provoking sunburn and skin cancer, also caused by UV-A.
  • UV-C these are the shorter and more energetic wavelength lights, that can destroy genetic material in humans or viral particles. UV-C lights are filtered by ozone in the atmosphere
  • Use of UV-C for disinfecting

    According to Air Science website: “Ultraviolet light is proven to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. In light of the current Coronavirus outbreak, UV germicidal lamps are being used to aid in disinfection of air, surfaces and equipment within hospitals and healthcare facilities, to help reduce and control the spread of the virus”.

    The use of UV-C lights on different surfaces as a cleanser is well established in hospitals, it eliminates 95% of aerosolized H1N1 influenza, the flu and superbug.

    UV-C is used for disinfection with applications in water treatment, air systems, and surfaces. DNA and RNA (genetic code for all life forms) absorb UV-C radiation by changing its structure and inhibits the affected cells´ ability to reproduce, so they are no longer dangerous. Although the quantity of UVC lights to inactivate different microorganisms varies and some are immune to this treatment.

    UVC´s ability to inactivate bacteria and viruses is the same principle that makes it damaging to human cells that also contain DNA. And it is why exposure to UVC is regulated globally, with the common agreement that it is harmful and presents a risk for human health.

    Some of the recommended precautions when handling UCV radiation sources include: wearing appropriate PPE (long sleeve clothing, gloves, opaque face shield), and to avoid this type of radiation on the skin, eyes, or any body part.

    These are some of the reasons why UVC lighting is not recommended to the used on humans to disinfect or to treat the virus. It is useful however to disinfect surfaces but not to be used on people. It is very important to take into consideration the opinion of experts in the field before exposing yourself to UV lights, that might kill COVID-19 but are not safe on humans.

    The International Ultraviolet Association (IUVA) and RadTech North America are educational and advocacy organizations consisting of UV equipment vendors, scientists, engineers, consultants, and members of the medical profession, states: “We would like to inform the public that there are no protocols to advise or to permit the safe use of UV light directly on the human body at the wavelengths and exposures proven to efficiently kill viruses such as SARS-CoV-2. UV light under the conditions known to kill such viruses are also known to cause severe skin burns, skin cancer, and eye damage. We strongly recommend that anyone using UV light to disinfect medical equipment, surfaces, or air in the context of COVID-19, applications that are supported by sound scientific evidence, follow all recommended health and safety precautions and to avoid direct exposure of the body to the UV light.”
