I worked in the HP inkjet division they spend hundreds of millions developing the pens and films used on papers and for the transparency’s. It sounds like a cool idea but creating a uniform coating that is compatible with the ink that that will dry without smearing and provide the resolution that the printer is capable of is a tall order.

Trying to add them to the ink will probably clog the nozzles of the print head, if you have cartridges with a new print head you could give it a try but many of the refiller kits create leaks and damage the printers .

Can it be done possibly , but I doubt it as the mechanism to create the jet of ink is a simple very tiny resistor that actually boils the ink and squirts it through an orifice. A change in the viscosity will change the droplet size and the refill rate. Additional materials if particulate will quickly plug the ink Chanel’s , these Chanel’s are very tiny some of the newer ones are created with lasers, Many of the older pens were created with abrasive profiling using 25 or 50 micron sand depending on the type of pen those wafers were cleaned many times because the residue would cause failures.

So it sounds neat but probably will not really work.
