Colors will appear different on this colored paper compared to when printed on a white paper.
We do not "print" white ink (although we do offer white foiling or screen print at an additional cost). Elements in your design that are white will end up being blank (hence showing the green paper).
The paper stock will also affect the way that colors appear. Colors in the green, yellow, cyan spectrum will tend to not be visible as the green color of the paper will not contrast enough with the ink. This is also the case with light and pastel colors.
As the Green Kraft is textured it does not hold fine detail.
