To give an idea of what is possible and what I created myself using a desktop printer (Epson 2100/2200 and Epson R1800) here an example.
I am using high quality acid free art canvas and the pigment inks from Trident in order to make durable and light fast reproductions.
The framed size is 32 by 42 Inch.
