Large Format Photography to Grand Format Printing

[Print2]

Hi All, I'm glad I found this forum, looks like just the job.
We are a company that print digital Wallpaper, Canvas, Rollerblind and NOW Flooring. We have a world wide Patent Pending on a new vinyl cushion floor product. Basically my question is, if i can print a wall from a digital camera of about 12 million Megapixle, what quality am i going to get from scanning from a 4 x 5 negative? I need to shoot a series of images to use as flooring, like Grass, Sand, Water, Cobbles, snow, Etc. I'm guessing that the quality of large format photography is second to non, so is this the route i should be looking at or should i stick to digital and maybe get the images shot on a 50 + million megapixle camera?

The printer that we are printing the floor on is 5 Meters Wide, but we can tile the width with an artwork overlap, so the images could be blown up to any size".

What about 8 x 10? Could this be the way to go? Or will 5 x 4 do the job.

Kind Regards
Kristian

Whats the smallest resolvable detail you can print?

there are step and repeat camera systems which are built for digitising large carpets 5x10 meters with enough detail to see the stitching.
