The success of the hardcover binding process depends on effectively bonding the book block to the hard cover, ensuring the finished product is durable and suitable for long-term storage. While wireless binding and hardcover finishing may seem less cost-effective compared to digital printing for short-run jobs, they are distinct processes that can complement each other when properly integrated.
To achieve a seamless workflow between printing and post-press operations, careful planning and layout design from the start are essential. Here are some key considerations during production:
1. **Folding**
Because digital ink sits only on the surface of the paper, folding can lead to cracking or breakage. To prevent this, it's recommended to crease the paper before folding. This helps maintain the integrity of the printed image and ensures smoother handling during subsequent steps.
2. **Laminating**
Applying a laminate to digital prints—especially after large-area printing—offers added protection during post-press processes like cutting and packaging. However, it’s not always beneficial to apply a single-sided coating to a double-sided print. The uncoated side may be more prone to color loss due to friction during later stages.
3. **Saddle Stitching**
This method is ideal for most digital prints, particularly for thin publications such as guides, brochures, and pamphlets. Saddle stitching is both cost-effective and efficient, allowing for online integration with other finishing processes like collation, folding, and cutting. It supports fast turnaround times, which is crucial in digital printing.
4. **Flat Booklet Binding**
When designing a flat booklet, it's important to leave sufficient space for binding. For example, if using an O-spiral with a 3:1 hole ratio (three holes per inch), a 3/8-inch margin should be left near the spine. For a 2:1 ratio, a 1/2-inch margin is needed. Most design software doesn’t account for slight changes in paper thickness after printing, but digital ink can alter the sheet’s thickness, affecting the final binding accuracy.
5. **Wire-O Binding**
Similar to offset printing, wire-O binding for digital prints requires attention to the binding amount. A 1/8-inch margin should be left on the back of the book, and a 1/8-inch cut margin on the other sides. Additionally, a 1/4-inch glue area at the bottom of the cover helps prevent glue from seeping into adjacent pages. The cover should also extend slightly beyond the text to ensure proper alignment.
6. **Hardcover Binding**
The main challenge in hardcover binding is securely attaching the book block to the case. Although wireless binding and hardcover finishing might appear time-consuming and costly for short runs, many post-press companies now offer pre-made hardcovers in various colors, styles, and sizes tailored for digital printing. This makes wireless glue and wire-O binding popular choices for digital printers, offering both durability and flexibility.
