Join Anne-Marie Concepción for an in-depth discussion in this video Creating and optimizing a cover image, part of InDesign: Creating Fixed-Layout EPUBs.
In the EPUB specification covers for your ebooks need to be called out in a special. And InDesign will take care of that for you. Now I am going to show you how it does so. There you have a few different choices. Here I have our friend The Little Red Hen ebook. All right. It's not an ebook yet. When you export it to EPUB. I'll go ahead and choose Export. You have the choice of what to do with the cover. Do you want to rasterize the first page? Do you not want any cover whatsoever, or do you want to choose a different image to be the cover? Now I exported already as none and rasterized the first page.
And here is what it looks like in iBooks. So this is none, obviously. And this is rasterizing the first page. In this case, rasterizing the first page makes sense, because it looks like the cover. But then what that means is that people will open it up. And when they go to the first page, it'll look exactly like the cover, which could be a little disconcerting. Some people like that. It's really up to you. Now the other thing to keep in mind, though, is that sometimes the cover isn't really a good choice to be the cover of the eBook. Here we have FlyAway, which is an interactive PDF that we're converting to a fixed layout EPUB.
And FlyAway was meant that the first page is the table of contents. And you could tap on each one of these buttons, and won't be looking at this in much more detail in another chapter to go directly to that section of the ebook. This could be considered a little busy, you know, too much information for the cover, so instead you might want to redesign the cover or have somebody design it for you so that it's a lot simpler. That's what I've done here as another InDesign document because simply, it was just easier for me to copy and paste and format text.
And then I exported this to JPEG by just going to the File menu and choosing Export, choosing JPEG at the bottom. And saved it out as Cover.JPEG, which is right here. When you do so, I'll go ahead and choose replace, but we're going to click Cancel here. You can export just a selection as we did before when we were talking about graphics or a number of pages, but right now we just want page one. And it's only a one page document, so All is fine as well. And you want to give it a resolution though of at least 150 pixels.
Now actually, I think. If I said at least, maybe that would be the maximum. Because you have to careful and stay within ranges of what the ebook resellers want you to keep within as far as image size is concerned. I'll show you that in a second. But I've already. As I said, I've already exported this. So if I go to FlyAway, my book right here, which is the entire thing, and I export this to EPUB. We'll export it to the desktop. And we want to export it as fixed layout. This time under Image I'm going to go ahead and choose the cover image right here.
Go ahead and export all pages, I'll click OK. This is a very common kind of alert that you get by the way when you export to EPUB if you have any groups. Saying that the image is going to look slightly different. Try exporting them to PNG. I really don't want care, so I just ignore that. And so there's our book, and that's the cover, and then that's the first page. And that kind of makes a little bit more sense. Now about those guidelines. Every ebook reseller, including the Apple iBook store, Kobo store, and so on have guidelines for ebook publishers.
And, Kobo is interesting because they recently published theirs in GitHub, which is an online repository for very geeky types. And here it's got all the specifications for how they want their ebook set up for their book store. And if I do a search for cover, you can see that they have a section on what to do with cover images. And it says, the optional ratio for coverage is 3:4, there's information about file size that content creators are advised to keep their cover images under 3 megabytes and so on.
So you definitely want to read up on these publisher guidelines, and I talk a lot about publisher guidelines and other cover considerations in my reflowable courses here on lynda.com. For example if you look up, InDesign CC: EPUB Fundamentals down here in chapter five I have one on creating a cover image with more information. As far as the cover of your ebook is concerned you can either create one yourself, have InDesign rasterize one for you, or hire it out to your favorite graphic designer.
