YA and I had some Subway last week and we each got a bag of chips to accompany our feast. We’ve had chips plenty of times but last week was the first time I noticed that there is are lines of colored dots along the bottom of the bags. I checked other bags in my house and about half had dots similar to these, although they weren’t exactly the same colors.
Didn’t take me to long to research this. These dots (apparently sometimes squares) are called “Printer’s Color Blocks” and they are used as quality control markers for the ink used to print on the bag. If there is too little or too much of a particular color, it affects the colors on the dots and the printer (human or machine) and adjust as needed.
The reason that I didn’t see these color blocks on all my chips bags is that it’s completely voluntary. Some manufacturers don’t use them and some manufacturers trim off the numbers after printing.
According to online articles, the most common colors are the four major colors used in printing: black, magenta, yellow and cyan, although depending on the manufacturer (like my bag above) can use more if they want/need.
This was a much more pedestrian explanation than I was hoping for and has absolutely nothing to do with the food inside the bag. I was really looking forward to some secret code that I could learn and apply when shopping. Oh well; if it had, I’d be spending way too much time standing in the chip aisle at my local Cub!
What’s your favorite salty treat?
