Barcodes are more than just a series of patterns; they are standardized symbols that require precise printing to ensure their functionality and readability. The quality of printed barcodes is crucial, as it directly affects the accuracy of scanning and data retrieval. To achieve high-quality barcode printing, it's essential to implement a comprehensive and scientifically-based quality control system. First, the design of a commodity barcode must follow strict guidelines. Key factors include the uniqueness of the code, the contrast between bars and spaces, the width of the quiet zone, the height of the bars, the magnification factor, and the optical properties. These elements must align with national standards while also considering the aesthetic appeal of the product packaging. Next, the choice of printing medium plays a significant role in barcode quality. Common materials like paper, cardboard, plastic films, aluminum foil, and corrugated boards can be used, but care must be taken to avoid reflective, transparent, or poorly colored surfaces. If such materials are necessary for design purposes, surface treatments should be applied to the barcode area to enhance readability. It’s also important to select materials with good dimensional stability, minimal ink absorption, and smooth surfaces to ensure accurate printing. When ordering barcode films, it's essential to check details such as the type of barcode (EAN-13 or EAN-8), the film’s orientation (positive or negative), and the type of developer used. The selection of the film depends on the printing method and plate-making process. For example, negative films are typically used for relief and flat printing, while positive films are used for gravure and screen printing. Before mass production, a printability experiment should be conducted to assess how well the printing conditions—such as equipment, material, ink, and environment—work together. This test helps determine the necessary adjustments to the barcode film and symbol design, following the guidelines set by GB/T 18805-2002. The printing method also influences the final result. Lithography and gravure printing offer better stability and precision, making them ideal for various magnification factors. Traditional letterpress printing, however, is less reliable due to its inconsistency. If relief printing is required for other parts of the package, it’s advisable to use lithography for the barcode first, then apply relief for the rest of the design. Screen printing is suitable for medium magnification barcodes. Finally, quality inspection is a critical step in ensuring that the printed barcodes meet all required standards. Before trial runs and after final production, inspections should be carried out according to GB/T 18348-2001 to verify the quality and performance of the barcodes. This process ensures that the final product is both functional and visually correct.

Zipper Printing

Zipper Printing

Zipper Printing is the process of printing designs or logos on zippers. This is usually for promotional or branding purposes, such as adding a company logo to the zipper of a jacket or backpack. The printing process usually involves the use of a special ink that is applied directly to the zipper material. The ink is then cured or dried with heat or UV light to ensure the design is permanent and won't rub off over time. Zipper printing can be performed on a variety of zipper types including metal, plastic and nylon zippers.
