The success of the hardcover binding process largely depends on how effectively the book block is attached to the hard case, ensuring the final product can withstand long-term storage. While wireless binding and hardcover finishing may seem less cost-effective compared to digital printing for short-run jobs, they are not mutually exclusive—they can actually complement each other when properly integrated.
To achieve a seamless workflow between printing and post-press operations, it's essential to plan and design carefully from the start. Here are some key considerations during production:
1. **Folding**
Since digital prints only adhere ink to the surface of the paper, folding can cause cracking or tearing. To prevent this, it's recommended to crease the paper before folding, which helps maintain the integrity of the printed material.
2. **Lamination**
Applying a laminate to the surface of digital prints—especially after large-area printing—can protect the finished product during cutting or packaging. However, applying a single-sided coating on a double-sided print might not be ideal, as the uncoated side could lose color due to friction during further processing.
3. **Saddle Stitching**
This is a popular choice for many digital prints, particularly for thin publications like brochures or guides. It’s cost-effective, efficient, and can be done online alongside other processes such as collation, folding, and cutting. This makes it well-suited for fast turnaround times in digital printing.
4. **Perfect Binding (Flat Booklet)**
When designing a flat booklet, it's important to leave sufficient space for binding between the staples and the text. For example, with an O-spiral hole ratio of 3:1 (three holes per inch), leave a 3/8-inch margin; for a 2:1 ratio, leave a 1/2-inch gap. Many design programs don’t account for changes in paper thickness after printing, which can affect binding accuracy, especially with multiple sheets.
5. **Wireless Glue Binding**
Similar to offset printing, wireless binding for digital prints should consider the amount of glue used. A 1/8-inch margin should be left on the back of the book, and a 1/8-inch cutting space on the other sides. Additionally, a 1/4-inch glue area at the bottom of the cover helps prevent glue from seeping into adjacent books. The cover should also extend slightly beyond the text to allow for proper bonding.
6. **Wireless Binding with Hardcovers**
The main challenge in hardcover binding is securely attaching the book block to the case for long-term durability. Although wireless binding and hardcover finishing may appear less efficient for short-run digital jobs, many post-press companies now offer pre-made hardcover cases in various colors, styles, and sizes tailored for digital printing. This has made wireless glue binding and hardcover finishing a common and viable option for digital printers.
