Shen Hua: Special knife pad for hardcover books, periodicals and albums. With precise and seamless design, it enables the upgrade of publishing and printing quality, as well as cost reduction and effi
The die-cutting processes for hardcover books, art albums, children's picture books, and cultural and creative publications focus on non-scarred printing, precise smoothness, stable long sheets, and environmental safety. The core requirement is that the die-cutting process should be flawless, precise, smooth, and stable. The die-cutting tooling pads, as the core consumables in the die-cutting process, directly determine the quality of the finished products and the reading experience - they must perfectly fit the round corners of the spine, special page numbers, and die-cut hollows, while also protecting the printed patterns on coated paper and matte paper, preventing scratches, smears, and frayed edges. They must also meet the batch consistency requirements for long-sheet printing and the food-grade environmental protection requirements for children's picture books. Shenhua has been deeply engaged in die-cutting consumables for 22 years, accurately understanding the core pain points of the publishing and printing industry and focusing on the specialized research and customization of die-cutting tooling pads specifically for hardcover books and picture books. With the core concept of "non-scarred printing, precise smoothness, long-term stability", Shenhua has developed a dedicated die-cutting tooling pad solution for hardcover books and picture books, becoming a core supplier for dozens of leading publishing houses and large printing factories in China, and enabling the upgrade of publishing and printing quality.
Precision攻坚， solving the core pain points of die-cutting in publishing and printing
During its deep research in the die-cutting field of hardcover books and picture books， Shenhua discovered that the industry generally faces four core pain points， which directly affect the quality and reputation of the publications：
Insufficient protection of the printing surface： The printing patterns on coated paper， matte paper， and special papers are fragile. Traditional die-cutting tooling pads have rough surfaces and uneven hardness， and during die-cutting， they are prone to scarring the patterns， smearing the ink， and scratching the coating layer， damaging the visual effect of the publication；
Poor adaptation to fine processes： The round corners of the spine， special page numbers， hollow die-cutting， and the page-turning structure of picture books have extremely high requirements for die-cutting precision. Traditional tooling pads have insufficient cutting precision and are prone to edge roughness， uneven die-cutting， and missed cuts， unable to present the design effect；
Poor stability in long-sheet production： The printing of book and picture book publications is large in batch size and long in editions. Traditional tooling pads have a rapid decline in rebound performance， resulting in inconsistent die-cutting effects in the early and later stages， batch defects， and even complete batch scrapping， causing huge cost losses；
Difficult to meet the environmental protection requirements for children's picture books： Children's picture books and early education reading materials need to come into direct contact with children and even be chewed and bitten. Traditional tooling pads are prone to releasing harmful substances， generating odors， and not meeting the safety standards for children's products， posing serious safety hazards.
Based on 22 years of precise die-cutting consumables technology accumulation， Shenhua has established a specialized research team for die-cutting tooling pads for publishing and printing， and collaborated with leading publishing houses and large printing factories to conduct joint research， overcoming core technologies such as non-scarred printing， precise shaping， long-term stability， and children's-level environmental protection. Over the past 22 years， the technology has continuously evolved： In 2020， it launched a dedicated die-cutting tooling pad for non-scarred printing， with a smooth and dense surface that does not scuff the printing surface or smear the ink； In 2022， it developed a round-corner and special-shaped model， with smooth and round-cut edges that perfectly fit the fine processes； In 2023， it optimized the long-sheet stability structure， with continuous die-cutting of 1 million times without performance decline， and 100% batch consistency； In 2024， it launched a children's picture book-specific food-grade and environmentally friendly model， which passed the GB 6675 children's toy safety certification， has no formaldehyde， no odor， and no harmful substances， serving over 40 leading publishing houses and printing factories， reducing the defective rate by 95% and significantly improving the stability of long-sheet production.
Core product matrix， suitable for all scenarios of publishing and printing
Shenhua focuses on the full-scenario needs of hardcover books and picture books， creating four series of dedicated die-cutting tooling pads. Each product has undergone rigorous non-scarred printing tests， precision tests， and long-sheet stability tests to ensure it meets the high-quality requirements of the publishing and printing industry. "Shenhua's special knife pad for book and magazine printing is the designated consumable material for our hardcover book project. Its most prominent advantage is excellent print protection, completely preventing any scratches on the printed patterns of the booklets. The rounded corners of the spine produced by the die-cutting are particularly smooth and slippery. Moreover, the long-run production process is stable, with consistent results both in the early and later stages. This has helped us solve many difficult problems in die-cutting of hardcover books, significantly improving the quality of our finished products." A production manager from a large state-owned printing factory commented.
Print protection without marks special knife pad: It focuses on protecting the print and preventing scratches, using a high-rebound and dense polyurethane substrate. The surface is treated with ultra-smooth processing, with hardness ranging from 25°A to 35°A. The elasticity is uniform and gentle. During die-cutting, it completely does not scratch the printed patterns, does not smear the ink, and does not scratch the coating layer. It perfectly protects the visual effect of the publication. It is suitable for various types of publishing paper such as coated paper, matte paper, lightweight paper, and special paper. The die-cut edges are smooth without burrs, eliminating burst lines and paper layer separation. It is the core standard model for hardcover albums, art publications, and photography collections.
Round corner special die-cutting knife pad: Focusing on precise forming and round, smooth edges, it adopts micro-nano precision cutting technology. It can precisely customize the curvature, width, and thickness of the knife pad according to the design requirements of spine round corners, special page numbers, and hollow die-cutting. The cutting accuracy reaches ±0.02mm. It has high rebound and anti-tear resistance, with smooth and round edges without saw teeth or gaps. It perfectly presents the design details of the publication, suitable for the special die-cutting needs of hardcover books, children's picture books, and cultural publications, solving the problem of traditional knife pads not being round and rough edges.
Long-run stable production special knife pad: With long-term rebound and consistent batches as the core, it uses a high-fatigue-resistant polyurethane formula. The rebound rate does not significantly decline after 1 million continuous die-cutting cycles. The die-cutting effect is consistent throughout the long-run production process, completely solving the problems of poor quality and batch differences in the early and later stages. It is resistant to wear and aging, with a service life more than 4 times that of traditional knife pads. It significantly reduces the frequency of machine shutdown and replacement, lowers the overall cost of long-run jobs, and is suitable for stable production of textbooks, best-selling books, and large-scale albums.
Children's picture book eco-friendly special knife pad: It focuses on being child-safe, odor-free, and anti-biting. It uses food-contact grade eco-friendly materials and passes GB 6675 children's toy safety certification and GB 4806 food contact certification. It has no formaldehyde, no heavy metals, no odor, and no harmful substances. Even if children bite and come into contact with it, there are no safety hazards. It is soft for print protection, does not scratch the patterns of the picture books, and the edges of the die-cutting are round and smooth without burrs. It prevents sharp corners from scratching children, perfectly meeting the die-cutting needs of children's picture books, early education reading materials, and启蒙 cards， and protecting children's safety from the source.
