The forms of精装书封皮 are divided into soft and hard types, with differences in material selection. Soft精装封皮 materials are mostly composite materials, which offer good strength and moderate hardness, but are not suitable for fine printing, only for embossing, screen printing, and hot stamping.

Only text and simple line patterns can be printed on the cover. Among several materials, leather composite materials have the highest cost and are primarily used for higher-end books; next are fabric composite materials (prices vary significantly within fabric composites due to different fabric types); plastic film has the lowest cost. Soft精装 covers are only suitable for smaller formats (typically books smaller than 32mo) and elongated formats.

Hardcover bindings are typically made by laminating a base material with a cover material. The base material for hardcover bindings is mostly cardboard.

Using cardboard to make book covers offers advantages such as good rigidity and low cost. However, the drawbacks include poor flexibility, prone-to-damage corners, and susceptibility to warping. These shortcomings can be mitigated through specific processing techniques during cover production. For instance, wrapping with fabric can enhance flexibility, while corner reinforcement prevents paper corner damage. Aligning the cardboard's grain direction with the spine and implementing heat-press drying treatments, along with selecting appropriate adhesives, can all help prevent cover warping.

The book cover is made of thicker white cardboard, which has less rigidity than strawboard but offers better wear resistance, folding resistance, and is less prone to warping. However, it is more expensive than strawboard and is suitable for mid-range精装 books. The cover paperboard specifically designed for book covers has excellent rigidity, wear resistance, folding resistance, and warping resistance, though it comes at a higher cost. It is an ideal material for producing high-end精装 book covers.

The outer covering materials of精装书壳 can also be divided into several different grades. The most economical type is the "cloth spine and paper cover," where the spine is made of materials like flexible painted cloth to create a "book waist," while the front and back covers are laminated with paper. Some books may use the same material as the spine for corner reinforcement to enhance durability. Another advantage of paper-covered精装 is the ability to print fine images and colors, enhancing the artistic appeal of the book's exterior, making it suitable for children's books and general reading materials.

Full-wrap book covers are also categorized into several grades based on the covering materials. The durable and cost-effective fabric covering material is coated synthetic fiber fabric, which offers excellent strength and resistance to acids and alkalis while retaining distinct fabric texture. A superior covering material is paint cloth, known for its dimensional stability, abrasion resistance, folding endurance, and moisture resistance. It is ideal for long-term storage and resistant to insect damage, making it a common choice for hardcover book covers. In recent years, a growing variety of synthetic fabrics specifically designed for book covers have emerged, with some materials outperforming paint cloth at a lower cost, providing better options for hardcover cover materials. Therefore, designers working on book covers should stay updated on developments in these new materials.

The cover materials of high-end精装 books often feature premium fabrics, aiming for a luxurious feel. Commonly used silk textiles include satin, brocade, satin, brocade, and chiffon. The choice of fabric colors and patterns can be tailored to the book's content and intended usage. Some designs boast vibrant hues, while others exude an antique charm or simple elegance. Only when these elements harmonize with the content and purpose can the design be considered ideal.
