Page layout for anything longer than a flyer, where master pages, styles, threaded text and a real preflight check turn a three hundred page book into something one person can actually produce.

About this release
Overview
InDesign is built for documents with structure. Text threads from frame to frame and page to page, so adding a paragraph on page four reflows the rest of the chapter instead of leaving you to fix it. Master pages carry the running heads, folios and grid. Paragraph and character styles, nested and applied by rule, mean a typographic decision changes everywhere at once rather than being retyped four hundred times.
For long documents the automation goes further. Tables of contents generate from paragraph styles and update on demand, indexes build from marked entries, cross references track their targets as pages move, and the book feature ties separate chapter files into one publication with synchronised styles and continuous page numbering. Data merge pulls a spreadsheet into a template for anything with variable content.
The output side is what makes it a production tool. Live preflight flags a missing font, a low resolution placed image, an overset text frame or an out of gamut colour while you work rather than at the printer. Package collects the document, its fonts and its links into one folder. Export produces PDF/X for print, interactive PDF with buttons and hyperlinks, EPUB with a proper reading order, and HTML for reuse.
What it does
Feature breakdown
Threaded text and master pages
Story based text flow across frames and pages, with masters carrying grid, folios and running elements throughout the document.
Paragraph, character and object styles
Hierarchical styles with nested and GREP styling, so complex typography is defined once and applied consistently.
Long document tooling
Generated tables of contents, indexes, cross references that follow their targets, and the book panel for multi-file publications.
Live preflight
Continuous checking against a profile for missing links, low resolution images, overset text, colour space problems and font issues.
Package and print output
Collect document, fonts and links into one folder, then export PDF/X with bleed, marks, colour conversion and transparency handling.
Interactive and digital export
Buttons, hyperlinks, animation and page transitions for interactive PDF, plus reflowable EPUB with a controlled reading order.

Release notes
From whoever packed it
- Documents saved here will not open in an older release. Export IDML if you have to go backwards.
- Missing fonts are reported on open. Install them before you start editing or the layout will reflow.
- Keep linked images in a folder next to the document. Packaging before archiving avoids broken links later.
