Here’s another tip for you!
When you’re printing a comic, you have to account for all of the pages. The number of pages has to be divisible by four.
Your 22 page book? That’s only story pages. You also have to account for the cover. That adds another four pages to the book. Ah, but 26 isn’t divisible by four, either. One way or the other, you have to add two pages in order to be divisible by four. And in adding two pages, you’ve got five pages to provide content for.
Stay with me.
22 pages of story for your book. That’s a given. (Your story pages will always be the base of your equation. Everything else you do will be based on that.)
Your cover will always be four pages: the front cover, inside front, inside rear, and rear. You will have to find content for three of those pages, because you already know that the front cover will be the image that entices someone to buy the book.
You now have at least two more pages of content to fill, in order to make the numbers turn out right.
With those two pages comes a decision: are you going to extend the story out another two pages, making it 24 pages of story, or are you going to create backmatter for the book? That backmatter can be anything: talking about the book, sketches, pages of script, whatever.
If you use these two pages for ads, I suggest reconsidering that, and suggest using the unused cover pages for ads. It’s only a suggestion, though. The reason is about aesthetics: even though comics you find on the stands have ads throughout the book, like commercials, your ads are going to be concentrated at the back, and they more than likely won’t look very good. (There are lots of reasons to sell ad space in your books, but more than likely you’re going to be doing an ad swap of some kind, and the books you swap ads with may aesthetically clash with yours.)
If you decide to use fewer pages (such as cutting off two pages of story to bring the total count to 24), then you have to do that for every subsequent issue. You have to turn the lessened amount of pages into a boon for you and your series.
There are many ways to make the page count work for you, but it is something you must always be mindful of. Figure it out now, before trying to figure it out at the last minute. You’ll be glad you did.
