myearwood Posted September 7, 2017 Share Posted September 7, 2017 Hey all Can someone confirm - if you have a UV source and do have regular ink - not uv curable ink, there is no chance of damage to the printer hoses by the UV? In other words, only if you run UV curable ink with the UV, then you must have the UV blocking hoses/lines and dampers? The concern is only the UV curable ink will polymerize in the head/lines/dampers, right? Thanks Mike Quote Link to comment Share on other sites More sharing options...
darryln Posted September 7, 2017 Share Posted September 7, 2017 yes, the ink will cure over time from ambient UV because the stock plumbing does not block UV wavelengths. Quote Link to comment Share on other sites More sharing options...
myearwood Posted September 7, 2017 Share Posted September 7, 2017 UV curable ink only will cure? The stock plumbing will not be harmed by the uv? Quote Link to comment Share on other sites More sharing options...

PITA Posted October 31, 2020 Share Posted October 31, 2020 On 3/27/2017 at 6:09 PM, UVDTG said: Good to know. Now I'm wondering if a lower wattage LED on the left side of the head to do a "pre-cure", then a strip of higher wattage LEDs on the front edge would be enough to work. I read from a professional UV printer maker that they post-cure (probably in the same way you are thinking of) to make sure all ink is properly cured. Just a little pre-curing might not be good as the ink could still flow around causing a not so accurate print quality. On the left side you have, I think, 10 mm (3/8 inch). That is enough space for LEDs of 30, maybe even 40 W. Usually that is enough to cure the ink. In some cases it might not be; then post-curing would be indicated.
