Inside my can of Pringles Prints was a potato chip that had the words “Printed fun on every one” and a weird pattern. At first I just thought it was just a fun different chip, but then I realized that this was no normal chip, oh no.
When pringles is printing their fun facts on their potato chips, every now and then they will print this pattern on a chip to indicate how much ink is printing on their chip during that run on the printing press. Those press machines are very delicate and complicated machines that have to run very large quantities of chips in a small amount of time. Pair that with the variables in the air (humidity and temperature), and the varying qualities of the chips, and you need a system that will ensure the right amount of ink is being printed on the potato chips.
Too little ink and the lines on the top and bottom would not show up on the
registration ink density chip. If there’s too much ink, then the lines in the middle would get all clogged up and you wouldn’t be able to see the space in the middle. It looks like the press at this time was running with a bit more ink than ususal, because the middle lines were appearing slightly clogged.
In the graphic design field these use similiar test patterns on paper to see how much ink the press is running so images don’t appear too dark or too light. It’s fun to see that it translates over to the field of potato printing. Certainly, it’s a work of art–a work of spud art, if you will.
