I have been asked to design a huge shop window wrap. The exact dimensions are 16640mm x 2400mm (yes thats 16m!). As a spec the printers have recommended working at 300 DPI, but making the image 50% or 25% of the size. So that makes it 150/75 DPI if I understand correctly.
Anyway, the graphic is to feature 5 product box images and a logo spaced equally along the length, so each product image is around 2773mm x 1200mm. The product images I currently have were shot by me with a Nikon D5100 at 16.2 mega pixels.
I am finding I am experiencing two major issues:
- The high res images of the product boxes are grainy. You can actually see the dots that have been printed.
- The image just doesn't blow up to the required size well. Colours begin to merge and definition is seriously lost. The white writing on the pack merges into the pink due to up sampling.
- How can I avoid the graininess of the photos of a printed box?
- Is there any way to negate the effects of enlarging the image? Would using a higher resolution camera make much difference with such a large image?
- How do professionals do this? I am guessing some sort of 3D modelling of vectors?
