Illustrator or InDesign for Catalog Layout? Decision Guide for Multi-Page Print-Ready PDFs

For multi-page catalogs, stop using Illustrator and switch entirely to InDesign for layout. Once in the prepress stage, be sure to follow the 'MINDS Three-Step Checklist for Print Submission': single-page output, verifying binding edge bleed, and checking page number logic

Working with so many corporate clients and design teams every year, the files I dread receiving the most are 100+ page product brochures created in Illustrator (AI). Once opened, not only does the computer fan spin furiously, but the artboards are all over the place, and the bleed settings are a complete disaster. The printed spreads don't align, white borders appear along the binding edges, and in the end, everyone is left staring awkwardly at each other over the proofs at the print shop

I often tell designers that AI is meant for vector illustrations and single-page posters. Using it to make a dozens-of-pages manual is like using a sports car to haul bricks. From a practical production standpoint, there are several insurmountable obstacles:

・Performance Disaster: Once you place dozens of high-resolution images in AI, saving becomes painfully slow. The app constantly crashes or freezes, wasting the designer's precious time watching the spinning wait cursor

・Bleed and Spread Blind Spots: Artboards in AI lack a 'Facing Pages' concept, making it extremely difficult to handle bleeds for images that span across pages. During imposition at the print shop, if the artwork does not extend properly into the binding margin, any cutting deviation will immediately result in visible white edges

・Page Number and Table of Contents Hell: AI lacks automatic page numbering and parent page (Master Page) linking. If a client requests adding two pages in the middle, every single page number has to be updated manually. This manual labor will absolutely drive you crazy when rushing to meet a deadline

InDesign is built specifically for multi-page editing. While you might find the initial learning curve a bit steep, once you get past the first couple of days, your efficiency will multiply

・Excellent Memory Management: Since images are displayed as low-res previews via links, running a hundreds-of-pages annual report is still smooth and seamless

・Parent Pages and Paragraph Styles: Headers, footers, and page numbers can be set up once and applied to the entire document. Editing a single paragraph style updates the body text throughout the book, which is a lifesaver during revisions

・Precise Facing-Pages Layout: With native support for left-to-right or right-to-left facing pages, the software automatically calculates bleeds for large spreads, ensuring your files won't get rejected by the print shop

Actually, I also frequently recommend that teams use large language models or image generation tools as creative assistants during the early ideation and style definition phases. However, when it comes to the final page layout and file preparation, make sure to switch back to InDesign. You can refer to the hands-on experience of the consultant team at MINDS Knowledge Academy; we help companies build this type of hybrid layout workflow

Choosing the right software is just the first step; exporting to PDF for printing is where the real test lies. Print shops use their own imposition software, so if your PDF settings are incorrect, we have to manually disassemble them on our end. Please keep the following specifications in mind:

・Must be Saved as 'Single Pages', Not 'Spreads': Uncheck the 'Spreads' option and export the PDF as a continuous sequence of single pages. The print shop's system needs to rearrange single pages for imposition based on the binding method. If you provide a spreads file, we cannot impose it at all

・Bleed Must Include the Binding Margin: A minimum bleed of 3mm is required on all four sides—top, bottom, left, and right. Many people assume that since the binding margin for perfect binding is wrapped inside the spine, it doesn't require bleed. This is incorrect. If the cutting blade shifts even slightly, a white edge will appear on the inner margin

・Page Numbering Sequence Must Match the Physical Book: from the front cover (P:

・1), inside front cover (P

・2), table of contents, all the way to the inside back cover and back cover, the sequence must be continuous. If there are blank pages, you must keep an actual blank page in the PDF; never skip page numbers on your own

Once the binding method is decided, the layout preparation details change accordingly. This is also where designers most frequently run into trouble

・Saddle Stitching Page Count Must Be a Multiple of 4: This is because a single large sheet is folded to make 4 pages before being stapled. If the paper is thick or the page count is high (e.g., 64 pages), be mindful of the 'creep effect'—the innermost pages will push outward and get trimmed more, so important graphics and text must be inset further

・Perfect Binding Spreads Must Avoid Gutter Loss: Perfect binding applies glue at the spine, causing about 5 to 8mm of the binding margin to get lost in the gutter. If you have faces or large headlines spanning across a spread, you should shift the text and graphics slightly outward in InDesign so that the visual looks complete when printed

If you are unsure about your files, consider reaching out directly to the prepress team at MINDS Printing (MS). For mid-to-high-end custom commercial printing, our in-house technicians will ensure these bleed and imposition details are spot-on, saving you the worry

For multi-page manuals, ditch Illustrator; InDesign is your only remedy against crashes, freezes, and revision hell

Golden Rules for PDF Export: single-page output, no spreads, and a minimum 3mm bleed on all four sides

For saddle stitching, calculate multiples of 4 and account for the creep effect. For perfect binding, watch out for gutter loss, and keep large spread images away from the binding margin

The choice of layout tool reflects a team's productivity ceiling. If your designers are still using Illustrator to piece together hundreds of pages of manuals, it is not a lack of capability on their part, but a workflow that needs upgrading. By adopting InDesign, incorporating automation scripts, and handing over the tedious prepress checks to a professional print shop, your design team can finally dedicate their time to creativity and layout aesthetics
