What are the advantages of UV curing technology? How does UV curing reduce print downtime? In the printing and packaging industry, equipment maintenance and press downtime control are important to increase business profitability and increase return on investment (ROI). This is mainly because most of the equipment in the enterprise is in a few shifts, and if it is stopped for a few hours when it is not appropriate, it will cause a big loss. Is there a solution to reduce downtime in printing equipment? The answer is yes, UV curing technology is one of its solutions.


Of course, to improve UV light curing, it is a strange word. Because UV curing is a highly reliable curing technology that can replace hot air dryers and other drying technologies, it has been widely used in the printing and packaging industry.


Advantages of UV curing technology:


One of the main advantages of UV curing technology is that the initial capital investment of the UV curing system is less. Compared with the investment in hot air drying equipment, the UV curing system can save 80% of the investment in equipment investment. Other advantages of UV light curing are increased production efficiency, improved print quality, and diversification of prints. In addition, the most prominent advantage is that UV light curing does not emit VOCs (organic volatiles) in the pressroom and in the surrounding environment.


The UV light curing system is simple to repair and operate, which is also an advantage of UV light curing. UV curing systems are advanced technologies that may be somewhat complicated to maintain and control when used in the first place. However, in reality, the operation and maintenance of a UV curing system is simple, the downtime is optimized to a minimum, and the UV curing system is easy to maintain and simple to operate.


The key to maintaining a UV system is to develop a preventive maintenance program and maintain a UV curing system in accordance with the plan. This means that the UV light curing system needs to be thoroughly inspected frequently, including a thorough inspection from top to bottom. Inspections include UV bulbs, lampshades and mirror pads, as well as inspections of mercury relays, capacitors and other electronic components.


Maintenance of the UV system:


UV bulbs are at the heart of any UV system. Properly maintaining and handling the UV bulb not only increases the life of the UV bulb, but also ensures that the UV bulb operates at maximum luminous intensity. A UV bulb inspection is performed once a week, mainly to find out if there are any of the following bad signs:


·The end of the UV bulb expands


·The end of the UV bulb is curled


·UV bulb ends whitish


· Dust and waste are deposited on the quartz glass


·The end of the UV bulb is inked


In the case of one of the first three items, the UV system requires air conditioning or water conditioning (the cooling of the UV curing system is incorrect).


In addition, it is also necessary to properly put the UV bulb. You should not hold the glass of the UV bulb yourself, but only hold the end of the ceramic or wear a pair of linen gloves. The oil on the skin will stick to the quartz glass. After a while, the oil will burn the UV lamp under the action of heat. Whenever you need to touch the UV bulb, you can remove the grease from the bulb by scrubbing the UV bulb with an alcohol cleaning solvent after contact.


The UV lamp cover itself also requires weekly cleaning and inspection. Carefully inspect the UV screen unit to ensure that no excess UV light leaks while ensuring that air can flow into the UV curing system. The air intake filter should be kept clean and free of dust and debris on its surface. If a quartz plate is used in the UV curing process, the quartz plate should be periodically cleaned to ensure that the properties of the transmitted UV light are still effective.


A good UV lampshade should use an air filter and valve working mechanism to maximize the effectiveness and reliability of the UV curing system. The filter should be clean and free of dust so that the airflow is not restricted.


Inspection and maintenance of UV mirrors is another simple way to ensure maximum efficiency in UV curing systems. For printing and finishing applications, UV mirrors are primarily used for focusing and subjecting the dried print to be cured to maximum UV light. Since 75% of the UV light reaching the surface of the print is reflected UV light, it is important to keep the liner clean and replace it as soon as the finish of the mirror finish is reduced.


There are many shapes, sizes, and configurations of UV power supplies. Most power supply transformers have mercury relays and capacitors to control the power output. The more advanced the power output technology provided by the UV curing system manufacturer, the more powerful the UV light curing system can provide. A PLC equipped with an HMI provides a graphical interface that enables control and tracking of the UV curing system.


  Precautions


When you buy a UV curing system, consider the following factors:


· Can your factory maintenance staff easily handle electronic components?


· Is the transformer compatible?


· Can the electric box cool down and does it have a lot of filtered air?


Considering the above issues before purchasing a UV curing system can save time and money.


The above mentioned work steps for using and maintaining a UV curing system may sound a bit cumbersome, but they are indeed a good way to save time. Weekly free time to do some preventive maintenance work, record the maintenance log, printers and finishing staff can make their UV curing system work optimally, and the equipment will be repaired and shut down. Time is reduced to a minimum. In order to facilitate troubleshooting, operation and maintenance of UV curing systems, UV curing systems manufacturers will provide a control platform that gives users full computer control.


In the printing and finishing industries, press downtime is unavoidable. Preventive maintenance is an easy way to avoid presses at the wrong time when UV light curing will increase productivity, improve print product quality, and diversify print services for printing and finishing. Before purchasing a UV curing system, keep in mind that the system's repair characteristics are in accordance with the UV curing system standards, so your company's press downtime will be minimized.
