Have you ever seen the different colored dots or small squares on a chip packet or a cookie box? Most people thought that these dots were printed for flavor, expiry, or food safety-related information when they saw colored dots on food packaging. When many of the colored dots are printed on a packet, it is common for people to be confused and think about it. 

But Guess what? These colored dots are not conveying any food-related information; they are printed for another purpose. So, in this blog, we will find out the real information and purpose behind the printing of these colored dots on chip packets or cookie boxes. Let’s get into it!

What Are Printer’s Color Blocks and Process Control Patches?

The colored dots on food packaging are basically the crucial sign of the printer’s color blocks or process control patches. These are the small dots, squares, or bars that are located on the edge of the packaging. They are not for people who buy those packages; instead, they are for the printing and packaging team.

These colored dots help printers ensure that every color is perfect and accurate on the packet. Most of them are called CMYK, which are cyan, magenta, yellow, and black inks that are used during printing. Additionally, you probably have seen the registration marks, which look like a crosshair, and they help to align the different colors perfectly.   

Why Are These Dots Important? 

These colored dots on food boxes packaging are crucial for brands to ensure their packaging always looks the same, no matter where you buy. Every brand depends on its color accuracy so that its product will easily be recognized when placed on the shelf. For example, a yellow signature on a bag of Lay’s chips or the classic red on a Coca-Cola can. Even a small color mistake can hurt trust and sales.

That’s why most of the companies use these packaging color marks for quality control. The printers and quality teams check these marks to identify the problems immediately, so that every batch or factory packaging always matches the original brand color consistency. This approach will help them to stop printing errors before the packaging reaches stores. 

Do These Circles Indicate Food Quality or Safety?

No, these circles do not indicate any food quality or safety. The purpose of the color dots is different country-wise, as in India, they indicate the flavor of the chips or information inside the food packaging. For example, the green color indicates that the food inside the packaging is vegetarian, and red means it's non-vegetarian. So, for American people, whenever you see these colored dots on the packaging, don’t think too much; it’s not related to you. 

What is the Meaning Behind Each Color Dot? 

It might be possible that when you see these color codes on any packaging or bags, you find it very simple and normal. But you know the real truth? Every color code has an important and specific function in the overall printing process. These color dots help printing and manufacturing to ensure design consistency, printing alignment during mass or bulk production, and color accuracy. Let’s take a look at each color in a detailed explanation: 

1. Black Color 

The black color represents the purpose of the sharp details, which include outlines, barcodes, and other small texts. The “K” in the CMYK process is called the black color, which helps the team enhance the readability and contrast of the background. 

2. Blue Color 

This color is linked with the Cyan component of the CMYK model, which is used to make the color tones in the packaging design. Blue color identifies and confirms the alignment of the Cyan plate in the printing process. If the printing team identifies that the blue control mark is not centered or shown as dim, it means there is a problem in the printing process which must needs to be corrected.  

3. Red Color

Red color means the blend of magenta, which is used to produce the attractive hues and warmer tones. These tones are used in logos, sale highlights, and other essential brand elements. The Quality Assurance team ensures that every red tone is printed perfectly. In case the color is not aligned or the ink fades in the area, it will negatively affect the branding of product boxes and visual appeal.  

4. Green Circle

Lastly, the green color dots on the food packaging are also part of the printer’s color test. It might be the blend of the yellow or cyan dot color, which is used to check the consistency in green areas of the design. 

Where do you find these Color Dots? 

The areas on packaging where you find these color dots are normally near the barcodes, flaps, seams, or along the edges of the packaging areas. These areas where color dots are placed are less noticeable. On chip bags, these color dots are placed closely with the heat-sealed edges or other bottom seam. You will see them near the glue flaps or along the fold on cartons and boxes. The placement of these color dots on the food packaging helps printers to find them without affecting the overall visual appeal of the packaging. Keep in mind that these color dots are different in size, material, or shape, and their location is consistent across various packaging types. 

Conclusion

To sum up the article, understanding the real information and purpose behind colored dots on food packaging is essential because many people think it's related to food safety, ingredients, or expiry. So, we mention everything related to the purpose and explain the meaning of each color separately.
