Description

Technical Field

[0001] The present invention relates to the technical field of packaging identification, and particularly to a composite label structure combining high-contrast color blocks and large character codes, which is applicable to improving the recognition efficiency of workers in the manual sorting scenario. Background Art

[0002] Currently, labor-intensive industries (such as footwear, clothing, and toy manufacturing) face the following pain points.

[0003] Aging workforce: The average age of practitioners exceeds 45 years old, and there are problems such as low educational level, deteriorated eyesight, and decreased reaction speed.

[0004] Difficult label recognition: Traditional sub-variety labels rely on small-sized pure character identification. Middle-aged and elderly workers need to observe closely for 3 - 5 seconds to recognize them, especially some foreign language markings are even more difficult to recognize.

[0005] High misloading cost: The manual sorting error rate generally reaches 5% - 10%, resulting in rework losses and customer complaints.

[0006] Existing solutions (such as enlarging the font size and adding barcodes) fail to balance the requirements of fast recognition and low-cost implementation. Summary of the Invention

[0007] The present invention provides a composite identification label with visual features, which realizes fast recognition at a distance of 1 meter through a dual design of a color identification layer (2) as the dominant and character assistance. Technical Solution

[0008] A composite identification label for preventing misloading of product packaging, comprising: a base layer, a color identification layer covering the surface of the base layer, and a character identification layer printed in the central area of the color identification layer.

[0009] Preferably, the base layer is made of ordinary self-adhesive material.

[0010] Preferably, the color identification layer is assigned a dedicated color system according to product categories / specifications.

[0011] Preferably, the characters of the character identification layer have a height ≥ 5 mm, and the color difference contrast with the color identification layer ≥ 2.5:1. According to some embodiments of the invention, such a design can effectively increase the probability of correct recognition at a long distance.

[0012] Preferably, the area ratio of the character identification layer is 60% - 80% of the color identification layer, and a solid color margin of more than 2 mm is reserved at the four peripheries.

[0013] Preferably, the composite identification label is pre-cut into independent sticker units and can be manually peeled off.

[0014] Beneficial effects: |Comparison dimension|Traditional pure character label|This invention| |Recognition distance|≤0.5 m|Color identification layer visible beyond 10 m| |Daily average efficiency|800 pieces / person (error rate 8%)|1200 pieces / person (error rate ≤2%)| |Training cost|2 hours per day to familiarize with character encoding|5 minutes to master the color system| Description of the drawings

[0018] The following describes the implementation manners of this invention with reference to the drawings.

[0019] The embodiment of this invention is for the scenario of manual sorting of shoes.

[0020] Label preparation: As Figure 1 shown, the base layer (1) uses 70 g / m² self-adhesive paper, and the front side is pre-cut into rectangular units and / or oval sticker units (4); As Figure 2 shown, the color identification layer (2) selects high-saturation color systems in the Pantone color card (such as Yellow 012C = 22.5 code, Blue 072C = 23.0 code, etc.); The character identification layer (3) uses the opposite color of the color identification layer (2), that is, when the color identification layer (2) is dark, the character identification layer (3) uses light-colored characters, and when the color identification layer (2) is light, the character identification layer (3) uses dark-colored characters.

[0021] In this embodiment, the color identification layer (2) is yellow, the character identification layer (3) is black, and the character 22.5 is printed on the character identification layer (3).

[0022] Structural parameters: The size of the pre-cut independent sticker unit (4) for shoes is 25mm × 18mm, oval in shape, and the size of the character identification layer (3) is 17mm × 8mm; The size of the pre-cut independent sticker unit (4) for the outer box is 50mm × 20mm, rectangular in shape, and the size of the character identification layer (3) is 30mm × 12mm; The distance between the color identification layer (2) and the character identification layer (3): The character identification layer (3) is printed in the central area of the color identification layer (2), with a solid color margin of more than 2mm reserved around.

[0023] Usage process: Workers manually peel off the pre-cut independent sticker unit (4) and paste it on the corresponding positions of the shoe packaging bag and the outer box respectively; During sorting and packing, first quickly classify by matching through the color identification layer (2), and then check the characters to confirm the accuracy.

[0024] Usage scenarios: As Figure 3 shown, after workers confirm the color identification layer (2) on the shoe packaging, they can distinguish the outer boxes with the same color from a distance.

[0025] According to some embodiments of the present invention, verify the influence of the area ratio (60%-80%) of the character identification layer and the color difference contrast ratio (≥2.5:1) on the manual recognition efficiency.

[0026] Experimental method: Sample grouping: Recruit 50 workers aged 45-60 years old, divide them into 5 groups, with 10 people in each group.

[0027] Test labels: Area ratio group: The area ratios of the character identification layer are 50%, 60%, 70%, 80%, and 90% respectively; Contrast ratio group: The color difference contrast ratios are 1.5:1, 2:1, 2.5:1, 3:1, and 3.5:1 respectively.

[0028] Test process: Workers need to identify the color of the color identification layer (2) at a distance of 10 meters; Record the single recognition time and error rate, and each group is tested 100 times.

[0029] Experimental results |Parameter type|Optimal range|Average recognition time (seconds)|Error rate (%)| |Area ratio |60%-80%|1.2-1.5|≤2.0| |Color difference contrast ratio|≥2.5:1|≤1.3|≤1.8| Key conclusion: When the area ratio of the character identification layer is less than 60%, workers need to observe closely, the recognition time is extended to more than 2.0 seconds, and the error rate rises to 5%; when the area ratio exceeds 80%, the lack of solid color margin leads to a decline in the color-dominated recognition effect. When the color difference contrast ratio is less than 2.5:1, the character recognition rate is significantly reduced, and the error rate reaches 4.5%; when the contrast ratio exceeds 3.5:1, the visual balance between color and characters is broken, and there is no significant improvement in recognition efficiency.
