Pitch Test
How does a pitch test work?
A pitch test consists of a number of horizontal lines that consist of very thin vertical lines. In each horizontal line the vertical lines are arranged differently. They are thicker or thinner. This fits exactly with the LPI value shown next to the lines.
The lenticular lens also consists of many lines. These lines must match the printed file perfectly. One of the lines will work perfectly if you place the lens over it.
Application of the pitch test
Lenticular lenses have a certain LPI value, or pitch . Then you're probably wondering: why should you still take a pitch test?
The pitch can differ due to a number of elements. First, the lens itself is almost never exactly the right value. So you will have to test each lens.
The print material also influences the pitch . Paper consists of fibers and comes in many different forms. This all changes how the ink ultimately ends up on the paper.
In addition to all this, the viewing distance can also change the pitch. The further away you look, the higher the pitch becomes. This also means that there is an ideal viewing distance for some lenticular prints depending on how the pitch is measured.
This all affects the pitch.
Even after a pitch test has been exposed to different temperatures and humidity for a long time, the pitch test can indicate incorrect values!
The pitch test is useful for every lenticular print. Every time this, quite a simple, file is needed to get a beautiful result.
