UV Printing apply on stainless steel cutlery

UV printing is a unique method of digital printing utilising ultraviolet (UV) light to dry or cure ink,
adhesives or coatings almost as soon as it's hit the paper, or aluminium, foam board or acrylic - in fact,
as long as it fits in the printer, the technique can be used to print on almost anything. Hereby the photos:

And we try to apply it on our cutlery set:

Is it food grade safe:
No, the handle is clear ink but it's not for your mouths, only the top part: functional part is safe without printing. 

Is it dishwasher safe:
It can pass 30 cycle dishwaser testing, but can't not be treated violetly after washing.
