The new HP Stealth Inkjet Printer Series allows users to add invisible "Stealth" content (text, graphics, barcodes, watermarks, signatures, etc.) to any pre-printed or blank document for a new advanced level of protection & authentication.
Stealth UV content is completely invisible until exposed to UV light source.
Stealth UV barcodes are completely invisible but can be scanned, registered, and validated using a UV scanner.
Add a layer of cutting-edge and uniquely specialized security & protection to anything that can be passed through a printer.
For best results both the black and the color cartridge would need to be replaced. Use Stealth iX Invisible Ink Enhanced Paper for a high quality print out. Use Stealth iX Invisible Ink Display Lights for the best viewing experience.
