Composition is the process of arranging the trademarks, graphics, text, colors and some symbols on the product packaging display surface to form a complete picture. In terms of composition elements, more emphasis should be placed on green and environmentally friendly information to make it a design mainstream. Trademark design is highly valued by the design and business circles because of its highly concise graphics, rich meaning and pivotal role in business. During the trademark design process, various factors such as the enterprise, product, technology, and environment should be comprehensively considered and analyzed. The characteristics of a trademark are determined by its function and form. It's about condensing rich information into more concise terms. A more general form is expressed in a relatively small space, while ensuring that the observer can understand its inner meaning in a short period of time. Trademarks are generally divided into three types: word trademarks, graphic trademarks and combination trademarks. The following points need to be considered when designing a trademark. (1) The space occupied by the trademark on the packaging should be large enough and its location should be very obvious. (2) The trademark should have original ideas and shapes. (3) The relevant provisions of the Trademark Law must be followed. (4) The trademark must have a unique personality, be easy for the public to recognize and remember, and leave a deep impression. (5) The trademark must have a sense of the times. (6) Trademarks must also be timely and practical. As the language of design, graphics are to convey the internal and external components to consumers in the form of visual images. The dialectical unity of content and form is a universal rule that graphic design should follow. In the design process, according to the needs of graphic content, corresponding graphic expression techniques are selected to achieve the unity of form and content in graphic design. Graphic design needs to consider the following points. (1) It should be rich in national cultural characteristics. Graphics can convey certain ideas. Pay attention to the different customs and habits of different regions, countries, and ethnic groups. (2) Graphic design must grasp the main features and pay attention to key parts and details. (3) Graphics should have distinct and unique visual effects, be simple but varied, complex but not cumbersome; simple but vivid, rich, complex but simple and perfect. (4) Pay attention to adapting to consumers of different genders and ages. Color is the first visual experience you get when looking at packaging from a distance. Surveys show that customers first feel about the color of a product, followed by the shape. Within the first 20 seconds of contact with the product, customers receive 80% color feedback and 20% shape feedback. Another rule also shows that shoppers observe each product for about 0.25 seconds. This 0.25 second glance determines whether consumers will turn from unintentional to intentional, thereby generating curiosity and desire to buy. Therefore, product packaging must attract people with its "color". Different products have different characteristics and attributes. Designers should study consumer habits, hobbies, and changing trends in international and domestic popular colors, and constantly enhance their awareness of color sociology and consumer psychology. Color design should meet the following requirements. Gender. content. Harmonized. The brand name, product name, description text, advertising text, manufacturer, company or distribution unit and other text information on the product packaging reflect the essential content of the packaging. When designing packaging, these words must be considered as part of the overall packaging design. The key points of text design on packaging are as follows. (1) The text content is concise. Real, vivid, easy to read and easy to remember. (2) The text design should reflect the attributes and characteristics of the packaging contents. (3) The arrangement of text and the overall design style of the packaging should be harmonious. (4) The text design should be sensitive to the times and regional. In addition to the above four elements, some other symbols should be used in packaging composition. Some are about transportation, such as moisture-proof, shock-proof, anti-inversion, waterproof and other storage and transportation signs; some are about safety of use, such as safety signs; some are about product categories, such as green environmental signs, recyclable signs, etc.: and convenience Commodity identification and circulation, such as barcodes, etc. Symbol design can be considered from the following aspects. (1) The printing size must comply with national standards. For example, when printing barcodes, the basic size (37.29mmx26.26mm) should be enlarged or reduced within the range of 0.80-2.09 times. (2) The colors of various symbols must comply with national standards and be consistent with the overall design style. (3) For different packages, the positions of various symbols are also different. Please check the relevant information to be foolproof. (4) The color of product packaging can be accepted by its consumer layer. (5) Color design should conform to the color preferences and habits of different sales regions. (6) The color design should be consistent with the texture and texture of the packaging materials used.
