I do all of my printing in house on a HP Designjet Z2100 Photo with HP Archival ink.
The paper I use is HP Premium grade Satin Photo.
The standard size is 30x45cm with a 5cm white border. The price for this is 75.00€
The price for a print in 50x70cm is 100.00€, this also comes with a 5cm white border.
If you want different sizes or to have the print framed, I suggest you go to my printservice at
