In today’s global market, EVA tool bags are favored by all kinds of wholesale buyers because of their lightness, durability, shockproof and other characteristics. As a key link in the production of EVA tool bags, printing operations can not only improve the beauty of the product, but also meet the personalized needs of customers.
1. The importance of EVA tool bag printing operations
The printing operation of EVA tool bags is an important link in increasing the added value of products. Through printing, brand logos, patterns, text and other elements can be added to the surface of the tool bag to enhance the recognition and attractiveness of the product. For wholesale buyers, customized printing can meet their needs for different markets and customer groups, thereby improving the market competitiveness of products.
2. Common methods of EVA tool bag printing operations
(I) Hot press printing
Hot press printing is one of the commonly used printing methods in the production of EVA tool bags. It uses high temperature and pressure to print patterns or text on the surface of EVA materials. The advantages of hot press printing include:
Clear pattern: It can achieve high-resolution pattern printing with strong detail expression.
Bright colors: It can be printed in a variety of colors to meet the needs of different customers.
Good wear resistance: The printed pattern has good wear resistance and is not easy to fade or wear.
(ii) Pad printing
Pad printing is an indirect printing method that transfers the pattern from the steel plate to the surface of the EVA tool kit through a silicone head. Pad printing is suitable for printing complex shapes and small areas, and has the following characteristics:
High flexibility: It can be printed on surfaces of various shapes and sizes, without being restricted by the shape of the product.
Low cost: It is suitable for small batch production, and the mold cost is relatively low.
(iii) Silk screen printing
Silk screen printing is a printing method that leaks ink onto the surface of the EVA tool kit through a silk screen. The advantages of silk screen printing include:
Rich colors: It can achieve multi-color printing, bright colors and long-lasting.
Strong adaptability: It is suitable for large-area printing, and the size of the pattern and text can be adjusted as needed.
Controllable cost: It is suitable for mass production and can effectively reduce unit costs.
(iv) UV printing
UV printing is a printing technology that uses ultraviolet rays to cure ink. It has the following advantages:
Environmentally friendly and pollution-free: The ink used does not contain volatile organic compounds and meets environmental protection requirements.
Fast printing speed: The ink solidifies instantly under ultraviolet light, and the production efficiency is high.
High pattern quality: It can achieve high-precision pattern printing, which is suitable for products with high requirements for printing quality.
3. Process of EVA tool kit printing operation
(I) Design stage
Before the printing operation, detailed design work is required. The key steps in the design stage include:
Demand communication: Fully communicate with customers to understand their needs and expectations, including patterns, text, color, size, etc.
Pattern design: According to customer requirements, design patterns and text that meet product characteristics and market demand.
Proofing confirmation: Make samples for customer confirmation to ensure that the design effect meets customer expectations.
(II) Material preparation
EVA material selection: According to product requirements, select suitable EVA materials, including its thickness, hardness and color, etc.
Printing material preparation: Prepare corresponding printing materials such as ink, glue, screen, steel plate, etc. to ensure that their quality and performance meet printing requirements.
(III) Printing process
Equipment debugging: According to the printing method and material characteristics, debug the printing equipment to ensure the stability and accuracy of the printing process.
Printing operation: Carry out printing operation according to design requirements, control printing parameters such as speed, pressure and temperature, and ensure printing quality.
Quality inspection: During the printing process, check the printing effect in time, find and solve possible problems, such as blurred patterns, color deviation, etc.
(IV) Post-processing
Drying treatment: For printed products that need to be dried, carry out appropriate drying treatment to ensure that the ink is completely cured.
Surface treatment: According to needs, the surface treatment of the printed EVA tool kit is carried out, such as spraying a protective layer, hot stamping, etc., to enhance the beauty and durability of the product.
4. Quality control of EVA tool kit printing operation
(I) Printing quality standards
Pattern clarity: The pattern and text should be clear and discernible, without blur, ghosting or defects.
Color accuracy: The printed color should be consistent with the design color, without obvious color difference.
Position accuracy: The position of the pattern and text should be accurate, meet the design requirements, and there should be no offset or skew.
(II) Quality inspection method
Visual inspection: Through manual visual inspection of the printing effect, obvious defects and problems are found.
Instrument testing: Use professional testing instruments, such as color analyzers, densitometers, etc., to accurately test the printing quality.
(III) Quality improvement measures
Process optimization: According to the quality test results, optimize and improve the printing process to improve the printing quality.
Equipment maintenance: Regularly maintain and service the printing equipment to ensure the normal operation of the equipment and the stability of the printing quality.
Personnel training: Strengthen the training of printing operators to improve their technical level and quality awareness
