CMYK Color vs. RGB Color

cmyk color

Before submitting your files for printing, graphics and colors should be converted to CMYK color. Often, photos are in RGB color and will need to be converted. Many people also design using Pantone colors, which should be converted to CMYK color. If you do not convert to CMYK color, there may be some color shifts when we convert the files before printing. These color shifts are more noticeable in background colors and less noticeable with photographs.

We do not match Pantone or PMS colors. Our prices are low because we use digital presses based on a pleasing color standard. A pleasing color standard means that the average person looking at the photo will find the photo pleasing — the sky is blue, leaves on trees green, a person’s face a normal skin tone. They will not notice anything out of the ordinary.

When working with colors, please be aware of two issues:

Blues — Often, a color that looks blue on your computer screen will have a purple tint when printed. To deal with this potential issue, set up the cyan and magenta values in that color so that there is at least a 30% difference.

Black — If your document contains large areas of black, please consider using a rich black (if your document is being printed in full color). Using 100% black for large areas tends to result in a muddy gray color when printed. Rich black contains values for cyan, magenta, yellow, and black, so it is really a full color process.  Our recommendations for values to use in rich black are:

Cyan 60, Magenta 40, Yellow 40, Black 100

Also, make sure that the black used in graphics and background colors use the same values. This is especially important when placing a photo with black around it on top of a solid black background. You may not see any difference on your computer, but often the blacks will look different when printed, unless the same values are used.
