Why Blue Light Fails UV Flatbed Printer Curing: Test UV-C Power?

Blue light (405-470nm) in UV flatbed printers is visible but ineffective for curing; true germicidal UV-C (200-280nm, peak 254nm) polymerizes ink by damaging bonds. Test with UV-C strips under the lamp—if no color change, output is low, causing tacky prints....
