Before You Start Designing
Setting up your files correctly at the start will save time and help prevent common print issues. For the best results, we recommend exporting your files as PDFs to preserve fonts, images, and layout. You can upload other file types, and we’ll convert them to PDFs.
If you use Adobe InDesign, Illustrator, or Photoshop, you can install Mixam’s .joboptions file. This preset optimizes your files for our presses by applying the correct CMYK color mode and recommended settings for bleed, transparency, and fonts.
How to Apply and Install Mixam’s .joboptions
Start by installing our preferred CMYK color profile: GRACoL2006_Coated1v2. Then download the relevant .joboptions file: Single Pages in Color or Single Pages in Grayscale. Follow the instructions for the relevant design program below:

Download Templates
One of the easiest ways to set up your files is by using a Mixam template. They’re available on all products and tailored to your print specifications with built-in guides for bleed, trim lines, quiet area, gutter area and spine width.
Templates help you:
- Avoid manual setup
- Avoid alignment issues
- Speed up the design process
- Ensure your files meet production requirements
- Reduce print errors
You can download a template from the Instant Quote Calculator after selecting your product specifications, or from the Artwork tab once you have started your order.
Pro tip: Templates are for setup only, so ensure you remove the template before exporting your final file.
Design Online
Mixam’s Design Online tool is another fast and simple way to create files for free in your browser that already meet our print requirements.
How To Use Design Online
- Choose your product and specifications, then click the Design Online option on the Instant Quote Calculator or by opening it in your pending order’s Artwork tab.
- Select which part you want to design: Cover & Body, Cover Only or Body Only.
- Add photos, text and graphics and click Save as you go. Mixam account holders can view and edit saved designs in their My Designs tab.
- Check your files to ensure they appear correctly.
- Click Finish & Upload to transfer your finished design to your Artwork tab.
Pro tip: If your design includes text and images, select the Advanced Editor option for maximum editing control.

Bleed, Trim, Quiet and Gutter Area
These are the most important parts of file setup:
Full Bleed Printing
Full bleed refers to the extra space where your design extends beyond the final trim size of your page.
Artwork that includes background colors or images must extend across the full bleed area so that even with small shifts during the trimming process, it prevents thin white edges from appearing on your final prints.
For most products, add 0.125" bleed. Hardcover Book covers require 0.8" bleed so your artwork can be wrapped around the cover boards. If your design does not reach the edge of the page, you may not need bleed. However, all files should still include bleed to prevent print issues.
Pro tip: Watch How To Set Up Bleed in InDesign, Illustrator and Photoshop for step-by-step guidance below.
Spines
The spine is the edge of a bound item where pages are joined. Its width depends on factors like page count and paper type. You can find your spine width in your cart’s order summary and order’s Artwork tab.
How To Set Up a Spine File
- Use the spine width provided and match the height to your trim size.
- Extend the file by 0.125" bleed on the top and bottom edges. For hardcover spines, add 0.8” bleed to the top and bottom edges.
- Export as a PDF with bleed settings included.
Spine Movement
Spine setup must allow for slight movement during the binding process. Tolerance movement is normal and adheres to industry standards.
- Spine position may shift by up to 0.08" left to right
- Spine position may shift by up to 0.125" up and down
Pro tips:
- Keep content 0.2” away from the top and bottom edges
- Leave 0.08” between spine text and cover artwork
- Avoid placing important content close to the edges
- Avoid using contrasting colors between the spine and covers in case movement occurs
- Avoid placing text on very narrow spines, as it may not be legible in print
Trim Lines
Trim lines mark the edge of your page after it is printed and cut to its final size. Your trim box must match your intended page dimensions. Do not include bleed inside the trim box. Any background colors or images that reach the edge of your page must extend beyond the trim line to the edge of the bleed area to prevent unprinted edges.
As a general guide:
- Position content 0.25" away from the trim line to avoid cropping issues.
- Position content 0.5" away from the binding area to ensure legibility.
Pro Tip: Watch our video guide below on setting trim boxes to ensure your pages are properly sized and aligned before exporting.
Quiet Area
The quiet area sits inside the trim line and prevents content from being cut off or appearing uneven during trimming.
General guidelines:
- Outer edges: Keep content 0.25” away from the trim line.
- Bound side (spine edge): Add 0.5” of space to prevent content from being trimmed or obscured.
- Hardcover Book cover spreads: Place content 0.6” away from the spine edge to avoid overlapping the hinge (the flexible bridge between the spine and the cover).
- Layflat binding exception: No quiet area required.
Quick Reference: Bleed, Quiet Area, and Binding Area
Use this quick guide to help set up your files correctly. For more details on binding options, visit our binding support page.
| Binding Type | Bleed | Quiet Area | Binding Area (Gutter) |
| Staple (Saddle-Stitch) | 0.125" on all edges | 0.25" away from the trim line | 0.5" |
| Perfect Binding (PUR) | 0.125" on all edges; top & bottom of spine | 0.25" away from outer edges | 0.5" |
| Wire-O Binding | 0.125" on all edges; top & bottom of spine | 0.25" away from outer edges | 0.6" |
| Spiral (Coil) | 0.125" on all edges; top & bottom of spine | 0.25" away from outer edges | 0.6" |
| Hardcover | 0.8" on all edges, include 0.2" hinge on each side of spine | 0.25" away from outer edges | 0.6" |
| Layflat | 0.8" on all edges, include 0.2" hinge on each side of spine | 0.25" away from outer edges | None required |
How to Create Single Pages
Single-page files are a common format for print. They work well for single-sided items like posters and bound items with small page counts. Clear file naming will also help keep your pages organised. Use simple names such as page1.pdf, page2.pdf, etc.
To prepare single pages:
- Set your page size to the final trim size
- Add 0.125" bleed (or 0.8" for Hardcover covers)
- Keep all important content away from the quiet area
- Export as a print-ready PDF with bleed enabled
Example (Perfect Bound):
Trim size: 8.5" × 11"
Add 0.125" bleed to each edge (0.25" total per dimension)
Final file size: 8.75" × 11.25"
Pro tip: If you use InDesign, make sure Facing Pages is turned off for single-page documents.
How to Create Double-Page Spreads
Double-page spreads allow content to run across two pages. They’re easy to organize and fast to upload.
To prepare spreads:
- Set your document width to double the width of a single page
- Add 0.125" bleed (or 0.8" for Hardcover covers)
- Keep content away from trim lines, quiet areas and the binding area.
- Offset images slightly on each page to account for the binding.
To offset images:
- Place each page’s content in its own frame or canvas. Do not use a single image spanning both pages.
- Shift the left-hand page image left by 0.125" and the right-hand page image right by 0.125".
- Make sure all backgrounds or edge images extend past the trim edge into the bleed area, with important content away from the binding area.
- Export your file with bleed included.
Pro tip: Watch How to Create a Double Page Spread below for a visual step-by-step tutorial.
How To Create Cover Spreads
Cover files are set up differently from interior pages. They include a front cover, a back cover, and a spine (if applicable). The front cover is positioned on the right, the back cover on the left, and the spine in the center. You can upload individual files for each component, but we recommend uploading a single cover spread for accuracy and design continuity.
When designing your cover:
- Place the spine in the center of the spread
- Leave a 0.125" gap on both sides (glue area)
- Keep important content away from trim lines
Items like staple-bound products do not require a spine design. If you print an item that includes a spine but you do not supply a spine artwork file, no printing will appear on the physical print, and it will be blank.
Fonts and Print Quality
Fonts can appear differently in print than on screen, and web fonts may not embed correctly. Additionally, TrueType and Type 1 fonts can sometimes cause embedding issues, so it’s best to convert text to outlines (shapes) before exporting to preserve their appearance. Always review your files to ensure characters display correctly.
How To Convert Text to Outlines
Adobe InDesign
- Select the Type Tool (T) and highlight all text.
- Go to Type > Create Outlines.
- Check that all characters appear correctly.
- Save your file with a new name to avoid overwriting the editable version: File > Save As.
Adobe Illustrator
- Select all text (Command/Control + A).
- Press Command/Control + Shift + O (or go to Type > Create Outlines).
- Check that all characters appear correctly.
- Save a new copy: File > Save As.
Adobe Photoshop
- Right-click the text layer in the Layers panel.
- Choose Convert to Shape.
- Check that all characters appear correctly.
Save a new copy: File > Save As, and select Photoshop PDF.
Pro Tip: Always keep an editable version of your file before converting text. Once outlined, text is no longer editable, only as vector shapes. You can also learn more about fonts in our blog post: Best Fonts for Books.
How To Upload, Add Blank Pages, Remove and Reposition Files
There are multiple ways to prepare and upload files you’ve created yourself. You can:
- Drag and drop files into the thumbnails in your Artwork tab
- Upload files from your desktop
- Upload from cloud-based platforms like Dropbox and Mixam’s WeTransfer account.
- Upload from a web URL
To add a blank page, click the three-dotted button under a thumbnail and click Insert Blank Page. A blank page will appear, and your quote will update.
To remove artwork files, click the three-dotted button underneath a thumbnail in your order’s Artwork tab and click Delete. You can then reupload a new artwork file.
To reposition a file, all artwork thumbnails must be filled first. Once they’re filled, you can either:
- Drag the file into a new position
- Click the three-dotted icon under the specific page, then under Move page to, enter the page number in the field and click Move. Your page will automatically appear in its new position. Ensure to double-check your page order so that your files are in the correct order before confirming.
Pro tip: Always remove old files before uploading updated versions. This prevents duplication and ensures the correct files are used for printing.
