IngramSpark File Creation Guide

Yeah… this part frustrates almost everyone.

You upload what looks like a perfectly fine PDF, hit submit, and then IngramSpark comes back with “File Not Approved” and some vague note like “margins too small” or “cover size incorrect.”

Feels like guesswork.

It’s not. There’s a pattern to every rejection I’ve seen. Once you understand how their system “thinks,” this becomes predictable.

Let’s fix that.

The #1 Reason Files Get Rejected (And How To Check It Fast)

It’s almost always wrong trim size or wrong PDF dimensions.

People assume:

“I selected 6×9, so my file must be fine.”

Nope. Ingram doesn’t care what you selected. It checks the actual PDF dimensions down to the decimal.

Here’s what I check immediately:

  • Open your PDF in Adobe Acrobat
  • Press Ctrl + D → Description tab
  • Look at Page Size

If it doesn’t say exactly something like:

  • 6.000 x 9.000 inches
    or
  • 8.500 x 11.000 inches

…it’s wrong.

Even 6.02 x 9.01 can trigger rejection.

Why? Because their print system is automated. No human eyeballing your file.

The Hidden Killer: Bleed Settings (Most People Miss This)

If your design goes to the edge of the page (background color, images, etc.), you need bleed.

No bleed = white edges after trimming = rejection.

Here’s the rule:

  • Add 0.125 inches bleed on ALL sides
  • So your file size becomes:
    • 6×9 book → 6.125 x 9.25 inches

Inside Adobe InDesign:

  • File → Document Setup → Bleed → set 0.125 in

Inside Microsoft Word:

  • Honestly? Don’t rely on Word for bleed. It’s messy.
  • Export → fix in Acrobat or switch to InDesign if possible.

This is the part everyone overlooks.

Interior File Setup That Actually Passes First Time

Let me simplify what Ingram expects.

Your interior PDF MUST be:

  • PDF/X-1a:2001 (this matters more than people think)
  • Embedded fonts (no exceptions)
  • Black text = 100% K (not rich black)
  • Images = 300 DPI minimum
  • No crop marks, no registration marks

If you’re exporting from InDesign:

  • File → Export → Adobe PDF (Print)
  • Preset → PDF/X-1a:2001
  • Compression → 300 DPI
  • Marks → unchecked everything
  • Bleed → checked (if needed)

If you skip PDF/X-1a, weird stuff happens:

  • Colors shift
  • Fonts substitute
  • Transparency breaks

And then… rejection.

Margins: Where Most People Get Burned

You think your margins are fine because they “look okay.”

Ingram doesn’t care how they look.

They calculate based on page count + binding type.

Here’s the quick reality:

Page CountMinimum Inside Margin (Gutter)
24–1500.375 in
151–3000.5 in
301–5000.625 in

Outside margins? Keep at least 0.375 in.

Critical rule:
Text too close to the spine = instant rejection.

I’ve seen perfect books fail just because page numbers were 0.2 inches too close.

Cover File: Where Things Get Messy

This is where most people spiral.

Your cover is not guesswork. Use their calculator.

Go to:

  • IngramSpark Cover Template Generator

Enter:

  • Trim size
  • Page count
  • Paper type

Download the template.

Do NOT design without this. Ever.

What That Cover Template Actually Means

When you open it, it looks confusing. Let me decode it:

  • Pink area → Bleed (extend background here)
  • White area → Safe zone (keep text inside)
  • Center lines → Spine width (depends on page count)

The one rule that saves you:

Keep ALL text inside the safe zone. Ignore your instincts.

Spine text?

  • Only if your page count is high enough (~80+ pages minimum)

File Naming Mistakes That Trigger Weird Errors

This one’s stupid but real.

Avoid:

  • Spaces
  • Special characters (#, %, &, etc.)

Use:

  • book_interior_v1.pdf
  • book_cover_final.pdf

I’ve seen uploads fail silently because of filenames.

Color Issues (Why Your Book Looks “Off” in Print)

Screen ≠ print.

If you designed in RGB:

  • Colors will shift during conversion

Ingram prints in CMYK

Inside InDesign:

  • Edit → Convert to Profile → CMYK

Inside Acrobat:

  • Tools → Print Production → Convert Colors

Deep blacks especially get ruined if you don’t control this.

The “Fonts Not Embedded” Error (Quick Fix)

Classic one.

Even if you think fonts are embedded… they sometimes aren’t.

Check in Acrobat:

  • File → Properties → Fonts tab

Every font should say:

  • Embedded or Embedded Subset

If not:

  • Re-export with:
    • “Embed all fonts” checked
    • Avoid system fonts like Calibri if possible

Still Getting Rejected? Run This 2-Minute Checklist

Before you upload again, scan this:

  • Page size EXACT match to trim size
  • Bleed added (if needed)
  • Margins meet minimum gutter requirements
  • PDF/X-1a export used
  • Fonts fully embedded
  • Images 300 DPI
  • Cover built using Ingram template
  • File names clean (no weird characters)

If all of that is correct, your file goes through. Every time.

The Weird Edge Case Most People Never Figure Out

Transparency.

If you used:

  • Drop shadows
  • Transparent PNGs
  • Effects in InDesign

…and didn’t flatten properly, Ingram can reject the file or print artifacts.

Fix:

  • Export using PDF/X-1a (it forces flattening)

This alone fixes a surprising number of “mystery” errors.

When You’re Done (And It Actually Works)

You upload.

No errors.

File gets approved.

That moment? Relief.

And here’s the thing—now you understand the system.

Next book will take half the time.

And if someone else is stuck staring at “File Not Approved”… you’ll know exactly where to look.
