The maximum ink coverage we allow is 300%.
This means that the total of the percentage values in any part of your design should not total more than 300. For example, a navy blue colour with values C: 100, M: 50, Y: 10, K: 40 has a total coverage of 200 (100 + 50 + 10 + 40).
Any coverage heavier than this may not dry correctly, or cause "rub-off".
