<p>I was at an art gallery in California and the walls were occupied by huge metal prints. They looked stunning so I went home and got on printed. They look different to me though. The prints at the gallery had no visible dots as if an inkjet was not used. The images' resolution looked "true to life". The metal print I got back from B&H or something (cant remember exactly where I got it from) looked like they took an aluminum slab and put it through and inkjet printer. I can clearly see the dots from the inkjet printer. Google doesn't really seem to be of much help to me, probably because I don't know exactly what to search.</p>
