What is a color space?
Color space is the range of colors that can be
accurately represented by a given process.
The human eye is limited to a certain range of color wavelengths
it can see. Most monitors and printers are even more constrained
in what colors they can reproduce.
If you have a calibrated monitor, it has been
standardized so that the colors you see match colors in your file
provided you are working in a defined color space.
Digital cameras and image editing software like Photoshop
have defined color spaces. If you are not working in a defined color space,
it is possible to make changes to the colors represented digitally
in your file that will not be displayed on your screen. You might push the colors in your file beyond what your monitor
is capable of showing you, and you’d have no way of knowing what
colors are actually in your file.
We recommend that you work on your files using
Adobe RGB 1998 color space. You
must have a defined color space for your ready-to-print files,
so that what we receive and print matches what you expect to see
from your file.
