The color of the pdf proof that you view on your computer monitor is only an approximation as colors vary slightly from monitor to monitor and from the color printing process that we use. If you are concerned about color, we can provide a hard-copy, high quality proof for an additional fee that will closely resemble the finished product. Any images or artwork provided in RGB will appear differently when printed. If you are concerned about color, we recommend converting your colors to CMYK before printing.
