Designing publications for the iPad isn’t much different than for print— knowing the basics of InDesign for page layout allows you to jump right into interactive tablet design by using the Folio Producer Tools. You can publish engaging brochures, magazines, portfolios and books using the Overlay Creator, Folio Builder and Adobe Content Viewer. Overlay Creator allows you to add iPad interactivity such as slide shows, links, pinching and zooming, movies and sound. Folio Builder uploads your pages to the Adobe cloud server, and the Adobe Content Viewer app allows you to view the publication on the iPad.

This tutorial will give you an overview of the process, instruct you how to get set up, and summarize the tools to add interactivity.

Software Setup

InDesign 5.5 includes the Overlay Creator and Folio Builder, both found under the Windows>Extensions menu. Adobe frequently updates the Folio Builder, so you may find that you’ll need to update first (Figure 2). In addition you will need to download and install the free Adobe Content Viewer app on the iPad to view the publication. The Adobe cloud service is free for single user distribution, but if you want to distribute your publication app through the Apple App Store, you will have to subscribe to Adobe’s Digital Publishing Suite (DPS). A free Adobe.com account is all you need to get started with the free single-user cloud service.

Note: For InDesign CS5, you will need to download and install Folio Builder from Adobe.com.

Design Specifications

To view documents horizontally and vertically on the iPad, you will have to design for both orientations. You can publish a single page (i.e. flyer), multiple pages in a single file (i.e. brochure) or have multiple files with multiple pages (i.e. magazine). Note that the specifications below are for the iPad2. For the new iPad, you just double the pixel measurements. This is what you’ll need:

• A horizontal page layout measuring 1024 x 768 pixels saved as a native InDesign file named as: yourfilename_h.indd

• A vertical page layout measuring 1024 x 768 pixels saved as a native InDesign file named as follows: yourfilename_v.indd

• A folder containing these files and any linked/imported images (Figure 3).
Note: Image files need to be saved as PNG.

• In the case of a large publication with a table of contents, such as a magazine, each article needs to be saved into a separate folder (Figure 4).

publication such as a brochure or a portfolio.

In addition, provide a thumbnail view for the app icon on the iPad created with these specs:

• A vertical thumbnail image saved as a PNG measuring 125 x 166 pixels named as: thumbnail_v.png

• A horizontal thumbnail image saved as a PNG measuring 221 x 166 pixels named as: thumbnail_h.png

As with all screen design, all images must be in RGB color mode. It’s in your best interest to not use high resolution images that you would use for print. If you plan ahead and save your image files no larger than 2000 x 2000 pixels as JPEG or PNG, that will save on processing time and potential flattening and conversion errors.

Working in InDesign

Create a new InDesign file for your publication:

• File> New Document and select Web with a 1028 x 764 option for iPad2 (Figure 5)

• Change your workspace set up in InDesign to Interactive (Figure 6) so you will see Media, Object States, Buttons, Overlay Creator and Folio Builder (Figure 7). If they are not displayed, you will also find them under Windows>Extensions and Windows>Interactive. In addition, the Hyperlinks panel found under Windows>Interactive offers other options for linking.

Listed below is a brief summary of what features each tool offers:

Media: Embed a small video and designate any frame to be the poster (the still preview frame displaying in the layout) along with a controller. Note that you can’t use Flash .swf files as iPad does not play that format. Quicktime (.mov) and MPEG files will work.

Object States: Set up slide shows, rollovers and destinations for hyperlinks.

Buttons: Create your own buttons or select from the sample buttons, then add a hyperlink. You can also create rollover states.

Overlay Creator: This is the last step before you upload your files to the cloud. There are seven options as you click on each one, a brief instruction will direct you how to set it up. For instance, when you click on Hyperlink, it instructs you to use either the Buttons panel or the Hyperlink panel to set one up. The Overlay Creator is specifically for setting up your interactive features for the iPad. There is a preview link at the bottom of the panel that will launch your document into the Adobe Content Viewer so you can check for proper set up.

Folio Builder (Figure 8 ): Uploads your files to the cloud for viewing and testing on the iPad using the Adobe Content Viewer app. You can also preview your document before uploading from this panel. The Viewer is also accessible from File>Folio Preview. In future tutorials, we will cover how to use buttons, set up a slide show, insert a movie and use the pan and zoom feature.
