l found the company that does the Ghost whites in both laser and ink. From my research the inks only work in Espon printers. Something to do with how their ink cartridges are make and how they print. Some ink printers l did not know use heat which would turn the white ink into goo and bugger the printer. As for Laser at the moment they only have l think two printer manufacturers toner cartridges available. Trust me when l say they are expensive. l have been looking into it for myself but like a lot of you guys l am not loaded with money
here is dealers available world wide
For you USA guys it is US Cutters.
It seems to be pretty straight forward as you only have to change out the black toner, turn your artwork into an black and white image then turn it into a negative image so all those white parts are black to fool the printer.
Unfortunately for me l have a Samsung C410 laser and a Canon ink printer both that does not have these cartridges available. l would have to run the expense of getting a new printer and the cost of the toner/ink
