What is ink coverage?
In full-color printing, colors are created using four primary colors: cyan, magenta, yellow, and black (CMYK). Each color can be used at a percentage ranging from 0 to 100%. When different colors are printed on top of each other, the total amount of ink used increases.
We refer to that total amount as the Total Ink Coverage (TIC) or maximum ink coverage.
A dark color composed, for example, of 80% cyan, 70% magenta, 70% yellow, and 100% black has a total ink coverage of 320%.
However, adding more ink does not make a color infinitely darker or more intense. At a certain point, the paper can no longer absorb the ink optimally.
What happens if there’s too much ink?
Excessive ink coverage can have various effects on the printed material. For example, the ink dries more slowly, which can cause smudging or bleeding. Colors may become less predictable, and the paper itself may react to the large amount of ink—for example, by warping.
Proper ink coverage is therefore especially important in large dark areas or images with a lot of shadows.
Not all paper reacts the same way
The amount of ink a sheet of paper can absorb depends, among other things, on the type of paper chosen. Coated paper absorbs ink differently than uncoated paper. The printing technique and desired finish also play a role.
That is why there is no single maximum ink coverage that applies to all printed materials. The correct settings are tailored to the material and the method used to produce the printed material.
The right balance makes all the difference
A high-quality print result, therefore, begins even before the file reaches the press. By taking into account color profiles, paper type, printing technique, and maximum ink coverage, we ensure that colors remain vibrant without using more ink than necessary.
At Hendrix Printing, we consider those technical details to be part of the overall printing process. After all, quality isn’t about putting as much ink on the paper as possible, but about using exactly the right amount.
