If you have CMYK images on your kraft product, when printing only 4-color, (ie: 4/0, or 4/4), colors will appear different to when printed on a white paper. CMYK images cannot be printed "true to color" on kraft cardstock without using a 5th Color White as a backer to your CMYK images(s). If you are color critical, please make sure to select Optional White Ink (ie: 5/0, or 5/5 if your job has double sided printing).

In addition, if you do not use a 5th Color White, elements in your design that are white will be blank (hence show the brown paper). The paper stock will affect the way that colors appear due to the slightly translucent quality of the ink (you will see the brown paper through the ink, especially in lighter shades). Colors in the orange, yellow, brown spectrum will tend to not be visible as the brown color of the paper will not contrast enough with the ink. This occurs with light and pastel colors as well.
