Meticulous Craftsmanship, Quality Assurance – A Chronicle of Xinsen Packaging's PS Plate Self-Adhesive Label Printing Production

In the current transformation of the self-adhesive label printing industry towards refinement and quality, PS plate printing, with its advantages of clear images and text, stable colors, and wide adaptability, has become the preferred choice for customized labels across multiple industries. Shandong Xinsen Packaging, deeply rooted in the packaging printing field, relies on professional PS plate printing equipment and a standardized system to meticulously create high-quality self-adhesive labels. Recently, we visited their production workshop and documented the entire production process of PS plate self-adhesive labels, experiencing the fusion of technology and craftsmanship.

Xinsen Packaging has focused on the R&D and production of self-adhesive labels for many years, assembling a senior technical team and strictly adhering to the ISO9001 quality management system. It has built a comprehensive quality control system from raw materials to finished products, and its products are widely used in food, electronics, clothing, wine, and other fields, enjoying widespread market recognition.

Xinsen Packaging's production workshop is orderly, and standardized operating procedures demonstrate its professional strength. The PS plate self-adhesive label printing process is meticulous, involving six core stages from initial preparation to final molding, each step embodying the rigor and focus of Xinsen's employees.

The first step is design and plate-making, which directly determines the label's appearance. The design team, combining client needs and industry standards, completes the graphic, color, and size design, including bleed areas. Technicians output the graphics to film, expose it with the PS plate, and then perform developing and fixing processes to achieve oil-water separation. The entire process is professionally controlled to ensure accurate printing and clear images.

The second step is raw material selection and pretreatment. Xinsen Packaging selects environmentally friendly self-adhesive substrates and uses environmentally friendly adhesives with significantly reduced VOC emissions that meet food contact standards. After rigorous testing, the raw materials are pretreated using specialized equipment to remove impurities and adjust tension, laying the foundation for printing.

The third step is the core PS plate printing process. Staff install the substrate and PS plate onto the printing press, precisely setting the printing parameters and using the oil-water separation principle to achieve image transfer. Technicians monitor the entire process, adjusting parameters promptly to ensure uniform label color, clear images, and no defects such as missing prints or ghosting.

The fourth step is post-processing, offering customized services such as lamination, hot stamping, and die-cutting according to client needs. Lamination enhances label durability, hot stamping elevates the premium feel, and die-cutting ensures precise shaping to specified dimensions. Xinsen Packaging is equipped with specialized equipment to guarantee precise and efficient post-processing, meeting diverse needs.

The fifth step is quality inspection. Inspectors employ a combination of fully automated and manual methods to comprehensively test label dimensions, color, adhesion, and other indicators. Substandard products are destroyed, ensuring a product pass rate of over 99.9%, upholding our quality commitment.

The sixth step is finished product packaging and shipping. Qualified labels are packaged in rolls or sheets according to customer requirements, with proper moisture and dust protection. A traceability system is established for precise delivery, ensuring comprehensive service quality control.

Mr. Ou, a representative from Xinsen Packaging, stated that they will continue to upgrade PS plate printing technology, introduce advanced equipment, optimize processes, and develop environmentally friendly material
