Heres a copy of whats on their site;
Photographic process prints are made using our Chromira. Known as digital C-Types, it produces digital C41 process prints up to 30" wide. Taking up the area of a small room, it is considered by those in the know as the cutting edge in digital photographic printing. Since a digital C Type is a true photographic process print, the colour integrity and ability for C Types to produce subtle variance of tone is unparalleled.
C-Types also have an outstanding capacity for longevity - which is why digital c types are considered by the industry as true archival quality. Using LED diodes to expose the paper, digital ctype technology means that for each red, green and blue channel, 256 levels of tone are able to be produced per pixel. The result - over 16.7 million possible variations of colour for each of the 300 points in an inch!
With the addition of a stunning array of paper types available, digital C Types are truly a revolutionary step in the ability for photographers, graphic designers, and visual artists to produce truly beautiful prints. Theprintspace use Fuji Crystal Archive papers to ensure prints are of the utmost quality.
From the examples I saw on a variety of different papers (Fuji Crystal Archive Matt & Gloss, Kodac Metallic and Fuji Transparent) and the prints just seemed richer/more detailed/more life like.
Heres the best part specifically about these guys (now I might not be in the know so I maybe getting over excited about this.)
30" x 40" = 40 quid (on any of those papers I mentioned)
30" x 90" = 90 quid (once again any paper) - thats 2.2,m x 0.75m ! Perfect for my panoramics.
Seems quite reasonable to me considering the sheer size of em.
