You are losing out on a wealth of information that is listed on the packaging of various items at the grocery store if you haven’t recently given it a closer inspection. The bright variety of dots you’ll find at the bottom of many boxes and bags is one of those ambiguous symbols that might be a bit confusing among the other symbols and signs you’ll notice on the packaging. Although many customers consider those dots redundant, they are there to ensure package quality control.
The coloured circles on food packaging can be pink, yellow, blue, black, purple, orange, or green, in a variety of light and dark tones. These colourful objects are apparently “printer’s colour blocks” or “process control patches,” and their purpose is to aid the printing crew responsible for producing the food packaging.
Technicians utilize colored circles to verify that the printing ink is the right [color] and quality before printing the package. To guarantee uniform brand colors, they compare the color to boxes printed all across the world. The majority of printers just employ cyan (blue-green), yellow, magenta, and black. Yet, some printers provide other colors including orange, green, and violet. This enables them to match difficult colors like FedEx purple and Home pot orange. Due to the requirement to test each ink color, some packages may have more circles printed than others.
The available colors must then be mixed by these printers to match the companies’ distinctive hues. These vibrant circles are printed on the backs or bottoms of packages so that anybody working on packaging can verify that the colors are accurate and printed on boxes in all packaging plants. Therefore, when you see those circles of color the next time, remember that they are there to make sure your product has the proper shades and hues.
