There are no restrictions on the amount of printing on your letterhead, however we do offer the following suggestions.
Please note that uncoated stocks do not hold ink colours as well as the ink soaks into the paper. This can make colours appear less vibrant when compared to the same colour printed on a coated paper. We are not able to offer colour matching.
Solid colour coverage on uncoated paper can cause inconsistency on the colour, especially in dark colours and greys. This is a restriction of the paper that cannot be avoided.
If you are printing on one of our coloured letterhead products (such as Pulp), please see the design considerations for this card stock also.
Papers with texture can also cause thin lines and detail to not print correctly.
