You can learn a lot from the design and color of food packaging.
The colored circles on food packages can come in a variety of colors. Apparently, those colored circles are called “printers’ color blocks” or “process control patches”.
We consulted an expert printing engineer, Meg Schiraldi, to find out exactly what the colored circles mean. “When the packaging is printed, technicians need to check the colored circles.
So there you have it! Colored circles on food packages help printers to match colors when they’re printing food packaging and ensure global brand consistency.
| A．Most printers only use the four colors. |
| B．This helps them match challenging colors. |
| C．Without them, food packages would be a mess. |
| D．There’re other things printed on the back of most food packaging. |
| E．The color of a packet of M&M’s, for example, can tell you the flavor. |
| F．They do that to ensure the printing ink is the correct color and quality. |
| G．And they’re there to help the printing team who print the food packaging. |
