What to consider before your wire-o bound book printing?

Book printing technology has evolved quite a bit over the past few decades. But one thing remains unchanged-- wire-o binding is still the most popular method for attaching your pages together. Here are some important things to consider before your wire-o bound book printing begins:

1)Who’s your target audience?

What are the books for? If you know who your target audience is, you will be able to better meet their needs in the project. Make sure this is clear before continuing with your printing project.

2) What size of wire-o bound book will you print?

There are two standard sizes of wire-o bound book. The larger one is 6" x 9", while the smaller one is 5.5" x 8.5". Of course, you can always make them in any size that satisfies your needs or fits your printing specs, but it's important to remember that wire-o size limits how many pages you can put in each book.

3) What wire-o material will you use?

Wire-o can be made from a variety of different materials, such as plastic, metal and even fabric - such as cotton and silk . Commonly used plastics include polypropylene and PVC. Polypropylene is the more economical option, but it is not as durable or recyclable.

On the other hand, PVC wire-o has a higher melting point, so publications printed on it last longer. But because of its chemical makeup, these books are harder to recycle and have a shorter lifespan overall. Metal wire-o is often more expensive, but it's just as durable as PVC wire-o. And lastly, fabric wire-o books are also fairly durable, but they are more expensive than polypropylene or metal options. They're not recyclable either.

Of course, it's also important to consider which materials fit within your budget and meet your printing specifications.

4) How do I know what size of wire-o hole punch I'll need?

Well, if you're using the standard 6" x 9", there's no need to get a special size (which would be expensive). You can use the same hole punches that you'd use for books.If you're printing a different size of wire-o bound book, you'll have to measure your spines and get a custom punch.

5) How thick should my wire-o bound book be?

In general, books with more pages are thicker-- so if you print a lot of pages (say 100 or more), then your wire-o bound book will be thicker. But chances are that people will be more interested in getting a thin wire-o bound book than something bulky and heavy.

6) What kind of paper do you want?

The thickness of your paper will influences how thick or thin your wire-o binding is. Generally, thicker paper need thicker wire-o binding, but both of these things depend more on the number of pages and covers than anything else.

7) How should I plan for bleed?

This depends on what kind of printing you're doing. Offset printing is the most common, but digital wire-o bound books are becoming more widely available. For offset printing, margins are different depending on what kind of paper you choose. If you select a thicker paper stock for your wire-o bound book, you'll have less margin-- which means it needs to bleed more so that no ink gets onto the spine.

8) How should I organize my images for printing?

Wire-o Bound Book Printing

Whether you're printing offset or digital wire-o bound books, make sure that all of your images are in the correct spot. Every image needs to be in a separate folder-- if it's not, your wire-o bound books will show an error or crash when you try and print them. Also make sure that all the images you include are well lit, professional and high resolution. Any image resolution in a printed project should be at least 300 DPI.It's also recommended break up large amounts of text with fascinating images or interesting graphics.

9) Who can help me design my wire-o bound book?

The best way to go about designing wire-o bound books is through programs like Adobe InDesign and Illustrator-- but both require some training before you can use them. If you're not a designer, you'd better ask your future printing company if it can help with design.

10) What's the difference between hardcover and soft cover wire-o bound books?

Wire-o bound hardcovers are printed on thick paperboard that is sturdy enough to stand up on its own. While wire-o bound softcovers can be opened more easily than wire-o bound hardcovers, but aren't as durable.

11) What's the difference between offset and digital wire-o bound book printing?

Offset wire-o bound book printing uses the same process as when books are printed on presses-- so when you print wire-o bound books, your files go through a press. Digital wire-o bound book printing produces your wire-o bound books in a different way, using digital printing technology that saves paper and is quicker than offset printing.

12) Is it necessary to print wire-o bound books on recycled paper?

If you want your wire-o bound book pages to be as durable as possible, it is best if they are printed on 100% recycled and acid free paper.
