I was so scared that I quickly looked at the toothpaste on the washbasin. It didn't matter at first glance,

Why is the facial cleanser also labeled in black? Is it also toner? Is it also on tissues? Is the small snack in your hand also included?

In fact, in production, machines use these positioning points to identify where the packaging needs to be cut, folded, or flattened.

So these color bars are positioned and identified during the production process. After the facial cleanser/toothpaste filling is completed, the hose is placed in the automatic tail sealing machine. The machine senses the relevant color points and starts to automatically seal the hose to ensure that the packaging is in the correct position during tail sealing.

Therefore, the color of the tail of toothpaste may not have practical significance for end users from above, but it plays a significant role in the production process. There are two main points:

Toothpaste tubes are mass-produced. Initially, the entire roll of hose material is automatically cut into the required size for each tube by the machine. In the automated cutting process, the positioning is tracked based on the color markings on the hose. As long as the sensors on the equipment scan the color cursor in sequence, it will be automatically cut; If this cursor is not designed, it is easy to have inconsistent cutting sizes.

The color cursor line at the bottom can also be used for identification, positioning, and measurement when sealing at the bottom of the paste tube, providing a reference line for centering the seal during sealing. Using this line as a baseline reference, there is almost no deviation from the centerline layout when printing toothpaste. Otherwise, without the color lines at the bottom of the toothpaste tube as a reference, the rate of defective and unqualified products on the toothpaste production line will greatly increase, affecting the production efficiency of the enterprise.

Generally, black schemes are used for calibration. However, in packaging design, there are still many complex situations, such as the appearance of calibration blocks in multiple colors or calibration blocks that are similar to the packaging color for overall aesthetics. In this case, a color code sensor that can stably detect and calibrate any color is needed. The Meiji ESE-10N color sensor, which can recognize even slight color differences, demonstrates its powerful performance in this regard.
