Do I need to use the CMYK palette?
No. Most documents and graphics submitted to print shops
use the RGB color palette. Scanners and digital cameras only produce
RGB color images.
Westside Instaprint will find the closest matching colors
between the RGB and CMYK palettes for every color in your files.
Photographs and Graphic design effects, transitions, gradients,
fades, blurs, anti-aliasing etc.. are ussually not noticablely affected
by the RGB to CMYK color transition.
You will most likely notice a color shift in large rich vibrant
color areas. Logos often have only a few colors, so you may need a
CMYK version of your logo for print media to keep you logo colors
consistent every time your logo is re-printed.
