Saving you time and money and kinder to the environment, the list of benefits goes on…


As end-users become more aware of the impact of environmental issues, whilst striving to reduce operating costs, a fuller understanding of the use of LED UV lamps in today’s printers can be highly beneficial. Becoming aware of the significant differences between LED UV ‘cold’ lamps and Metal Halide (MH) ‘hot’ lamps can help you make an informed choice.


The majority of UV cure printer manufacturers currently employ short life ‘hot’ Metal Halide (MH) lamps. Mimaki however, has been pioneering more technologically and ecologically advanced long life ‘cold’ LED UV lamps for some years now, and has thousands of Mimaki produced LED UV printers operating worldwide, to the benefit of their users and their users customers. As LED technology has progressed and become more effective and affordable than the short life ‘hot’ metal halide lamps, the benefits have become ever clearer.


LED UV lamps use 75% less electricity. A combination of LED reduced ‘on time’ and lower power requirement leads to an overall lower consumption. These lamps produce minimal heat, effectively running ‘cold’ (room temperature). This allows printing to sensitive media and avoiding any potential distortion or discolouration of media. Maintenance can be carried out immediately, thereby increasing productivity.


LED UV Lamps carry a 5000 hour lamp warranty which equates to over 5 years of typical daily use. LED UV lamps’ expected life is between 10,000 to 15,000 hours, while MH ‘hot’ lamps expected life is only typically 500 – 1,000 hours (*requiring change every 3 – 6 months). It could cost approximately £2-4k extra per year running costs for MH ‘hot’ lamps, as well as the consequent machine ‘down-time’ and loss of productivity. The UV intensity of MH ‘hot’ lamps deteriorates over a relevantly short period, whereas LED UV lamps have a much longer life, providing more consistent curing.


LED UV lamps produce significantly less CO² than MH ‘hot’ lamps and have a fully adjustable lamp intensity. MH ‘hot’ lamps have a restricted light intensity control and this restriction can cause inconsistent cure rates when print speeds are varied. LED UV cure lamps are physically smaller than MH ‘hot’ lamps, allowing for a more compact printer design.


Graphix Supply World carries a range of Mimaki UV printers including the UJF-6042, JFX200, JFX500-2131, UJV500-160, UJV-160, UJF-3042HG and the UJF-3042FX.
