HP Invisible Inkjet Cartridges

XNiteHP60-UVBlue

XNiteHP60-UVRed

XNiteHP60-IR1

XNiteHP60-IR2

We have developed invisible Ultraviolet (UV) and Infrared (IR) fluorescent inkjet cartridges.  We start with the HP60 high capacity cartridge and add specially purified versions of our invisible ink.  In UV, we have invisible blue and invisible red inks.  In IR, we have two different invisible inks that can be seen either with an IR camera and special filters where it absorbs light, or in another IR band as infrared fluorescence.  To see IR fluorescence you need an IR sensitive camera, special filter and an excitation source.

We are currently offering only the HP60 cartridges to replace the normal black cartridge in the printer.

Invisible inkjet printing is a great way to protect and verify documents.  Anything that can normally be printed with an inkjet printer can also be printed with an invisible UV cartridge such as checks, labels, tickets, tags, labels and regular paper.  Once printed, the UV ink is invisible until the document is held under a longwave UV fluorescent light source.  We have a wide variety of UV handheld light sources that are compatible with these inks.

Using the invisible inkjet cartridge is as simple as replacing the inkjet cartridge and proceeding with the printers alignment routine except that, since the alignment page is invisible, you will want to keep a normal black page if your printer is the type that expects to scan the alignment page.

When cartridge is not in use, we recommend that you remove the cartridge and snap-on supplied protective print head cap.  While all print cartridge slowly evaporate through vent holes and the print head nozzles.  Because the UV ink is more volatile than the normal water based ink, the cartridges lose ink more quickly unless you keep the cartridge capped when no in use.

When printing with invisible blue, please be aware that most white copy paper has fluorescent brighteners to make the paper look whiter.  These brighteners also fluoresce blue, so the invisible blue ink can be hard to detect on bright white paper.  We have special white paper available that does work with the invisible blue.  The special what paper also is non-acidic and can be used for archival purposes.

The invisible red UV ink is a much more difficult ink to make than the more common UV blue, and, because of this, the UV red is a much more secure ink.  If you need higher security, we suggest the UV Invisible Red inkjet cartridge.

Because these cartridges contain the print head, you don't have to worry about the ink destroying your printer.   Many of the UV invisible inkjet cartridges use printers integrated print heads that have large inkjet nozzle sizes such as Lexmark printers.  Typically, they are using inks that have very small particles of non-soluble UV material.  The problem with this approach is that some of the particles will eventually cause the print head to clog.  Once the print head clogs on such a printer, you have to throw away the printer because the print head can't be replaced.

With our HP inkjet cartridge system, the print head is part of the cartridge  We have also created special invisible UV inks that are solutions - not particle suspensions.  In normal light, our ink looks water clear versus the typical suspension systems that look like milk.
