What resolution do I need to reproduce my photo in print?
The rule of thumb that most people use is to scan at twice the line screen that you will print (a quality factor of 2). Most publications (magazines, brochure etc.), use at least 150ls which means you probably need at least 300dpi for most publications.

For large format inkjet print a resolution of 100dpi is fine.


What is the difference between a drum scanner and other scanners?
Drum scanners use a technology called photo-multiplier tubes (PMT's) rather than charged coupling devices (CCD's) to convert light waves into electronic data.
PMT's capture a longer smoother tonal range than CCD's and therefore can produce an image that is much closer to the original.
Generally, drum scanners have superior optical systems with better lenses and more consistent light sources, than there flatbed counterpart. Although this is starting to change with very high end flatbeds (those over £15,000), drum scanners are still the best technology for color scanning Pevensey Scanning use Crosfield scanners.


What is the largest original we can scan?
We can scan any size original up to 710mm x 505mm in size.


Why do some colors like bright blue and bright red look different in CMYK and in RGB?
RGB (visual light) has more colors than CMYK (printed inks) this is most apparent in very vibrant reds, blues and greens. Likewise monitors which are RGB devices are not good at accurately displaying cyan and magenta.
In other words, there are, unfortunately some colors you just can not reproduce with standard four color printing.
