If the positioning is good, the cutting length can be ensured to be appropriate; On the other hand, toothpaste needs a color code when filling, which can ensure that the patterns and characters printed on the package are correct when filling and sealing toothpaste.
2. In order to accurately locate the color code, when making toothpaste, the color bar at the bottom of toothpaste will be used, and the color bar will generally choose a color that is obviously different from the background color; In order to save the printing cost, the color of this color bar is usually selected from the existing colors on the toothpaste pattern, such as red, blue, green and black.

So generally, either the date of production or the date of production and the date of restricted use are written at the end of toothpaste.
