What are the principles of label design? Design tips to enhance brand image

The Underlying Logic of Label Design

A good label design is not primarily about "looking good," but about whether it can convey information within 0.3 seconds. There is a rule of thumb in the packaging industry: the average time a consumer spends scanning a product on the shelf is 3 seconds, with labels accounting for nearly half of the attention weight. A well-designed label can significantly reduce the consumer's choice cost.

The underlying logic of label design includes three levels: information readability (can it be clearly seen) → brand recognizability (do you know who it is) → emotional connection (do you want to buy it). These three levels progress sequentially and are indispensable. Many design problems arise from skipping the first level and directly pursuing the third.

Information Hierarchy and Layout

Golden Triangle Principle: Information on the label decreases in importance. The brand logo or product name is the first level of the information pyramid and should be most prominent. Core selling points (such as "alcohol-free", "contains hyaluronic acid") are the second level. Ingredient lists, net weight, and production information are the third level. This hierarchical relationship is achieved through a combination of font size, weight, color, and placement.

Font Selection: It is recommended to use custom fonts or standard sans-serif (Hei) series for brand names to ensure legibility at different print sizes. For body text and regulatory information, use highly readable Song or FangSong fonts with a font size no smaller than 7pt. Pay attention to the coordination between English and Chinese fonts—when using sans-serif fonts for Chinese, it is also recommended to use sans-serif fonts for English.

Whitespace and Information Density: A common mistake in label design is trying to enlarge and highlight all information. In fact, appropriate whitespace (20-30% blank area of the label) can actually improve the recognition of key information. However, whitespace needs to be adjusted according to the product type: minimalist whitespace for high-end skincare conveys a sense of sophistication, while excessive whitespace on drug labels with dense information may make the information appear incomplete.

Color Application Techniques

Color is the fastest emotional trigger in label design. Warm colors (red, orange, yellow) convey passion and appetite, suitable for food and snack labels. Cool colors (blue, green, purple) convey professionalism and refreshment, suitable for skincare and medical products. Black and white convey simplicity and high-end feel, suitable for boutique and premium product lines.

A practical color ratio: main color accounts for 60% (brand color), secondary color accounts for 30% (functional areas or category distinction), and accent color accounts for 10% (promotional copy or logo highlight color). The number of colors on a label should not exceed 4. Too many colors will distract attention and increase printing costs (spot color printing incurs additional plate fees for each extra color).

Impact of Materials and Processes on Design

A design draft may look great on screen, but when printed on an actual label, it can look very different—this is a common 'design failure'. The reason is that the limitations of materials and processes are not considered during design.

Transparent PET labels: When designing, consider the effect when applied to colored bottle bodies. White base color may require an opaque layer to improve opacity after labeling. Partial cutout designs that utilize the bottle body color as a design element often achieve a more premium effect than full-color printing.

Synthetic paper labels: They have strong ink absorption, and color saturation is 10-15% lower than coated paper. It is recommended to increase color saturation and contrast during design to compensate for color differences after printing.

Coated paper labels: Best color reproduction, suitable for fine graphics and text design. Lamination can improve color saturation and tactile feel. Matte lamination is soft and elegant, while glossy lamination is bright and eye-catching.

Impact of finishing processes on design: Hot stamping is suitable for line-type logos, with fine lines achieving a clean and crisp effect. Embossing requires sufficient paper thickness (no less than 300g/m²); paper that is too thin will not produce a noticeable raised effect. Partial UV areas should not be designed too small; the minimum line width should be no less than 0.5mm.

Barcode and Information Compliance Considerations

The barcode (EAN-13 or UPC-A) on the label should be placed on a flat surface, avoiding folds or rounded corners. The barcode color should be black bars on a white background for best readability. Gold, silver, or colored barcodes are not recommended—although they can be printed, the scanner's red light may not be able to read through certain colors.

Information required by regulations (production date, ingredient list, net weight, etc.) must not use materials that can be covered or wiped away. During proofing, check item by item whether the label content complies with the regulatory requirements of the target market—different countries have differences in font size, language, and warning statement placement.

Design Process Recommendations

Step 1: Determine the label size and shape, designing in conjunction with the bottle body or packaging structure. Step 2: List mandatory and optional information, sorted by importance. Step 3: Create a draft design in AI or CorelDRAW, marking process areas. Step 4: Digital proofing to confirm color and text details (3-5 working days). Step 5: Before mass production, conduct on-machine labeling tests to check labeling speed and positional accuracy.
