Fix This Now

Your issue: IngramSpark PDF Rejected

Step 1 (Required)

Use the correct tool to fix the root cause.

→ Use PDF Check Tools

Step 2

Fix export settings, fonts, or page boxes.

Step 3

Upload only the validated final PDF.

Why this happens (quick explanation)

For IngramSpark workflows, this checklist is for the broader class of PDF export and file-construction problems that can block approval before or during premedia review.

IngramSpark evaluates the exported PDF structure, including scaling behavior, compatibility settings, transparency handling, and print-ready geometry.

The file may be readable in a normal viewer but still fail if the export path changed the physical page boxes or resource structure.

Example error message

A realistic IngramSpark message for this issue may look like:

IngramSpark detected PDF export settings that are not compatible with the selected print configuration.

or

The uploaded PDF contains structural or scaling settings that prevent reliable print validation.

Quick Fix

Use this fix path for IngramSpark Complete PDF Preflight Guide:

1. Return to the source file and correct the export path, compatibility setting, or scaling option causing the issue.
2. Export a fresh print PDF with one controlled preset instead of using print-to-PDF or post-export edits.
3. Verify the final PDF structure before uploading again to IngramSpark.

The safest approach is to correct the source file or publishing setup first, then export a fresh artifact and validate that exact revision before resubmitting.

IngramSpark Rejected PDF Checklist

This checklist is meant to reduce repeated upload cycles by turning common IngramSpark rejection causes into checks you can run in the same order every time. If you work through the list before re-uploading, most failures move from "mysterious premedia rejection" to a measurable bleed, trim, spine, margin, or export problem.

Use this guide when any of the following change:

• trim size
• page count
• paper selection
• binding style
• cover template revision
• source file export preset

Treat the latest IngramSpark template output for your title as the authoritative geometric source. Use formulas and planning constants to catch mistakes early, then confirm final dimensions against that template before upload.

Most Common IngramSpark PDF Rejection Causes

The most common upload failures are usually geometry and production-file issues. Review these related guides for the highest-frequency rejection patterns:

• Bleed Missing
• Barcode Area Violation
• Hardcover Spine Shift

Quick Preflight Checklist

Before uploading your PDF to IngramSpark, confirm the following:

Check	Requirement
Bleed	0.125 in (3.2 mm) on all sides
Margins	Minimum 0.25 in safe area
Images	300 DPI or higher
Fonts	Fully embedded
Color	CMYK preferred
Trim Size	Must match metadata
Spine Width	Calculated based on page count

If any of these fail, your PDF may be rejected during the upload validation process.

Numeric tolerance tables

The tables below separate three different concepts that often get mixed together:

1. platform hard specs (must pass)
2. manufacturing drift (what print can physically vary by)
3. internal QA guard bands (how much margin your design team keeps so drift does not cause visible defects)

Table A: Geometry and layout tolerances

Check class	Platform hard spec / guidance	Recommended QA target (release gate)	Why this target matters
Manufacturing variance	1/16 in (0.0625 in / about 2 mm) possible trim/fold variance	Assume full variance in both axes during layout review	Prevents type and rules from appearing too close to trimmed edge after normal production drift
Interior bleed (top/bottom/outside)	0.125 in (3 mm) for full-bleed interior art	Exactly 0.125 in exported bleed and visual overfill past trim	Any under-bleed risks white slivers after trim shift
Interior bleed (bind side)	No bleed required on bind side	Keep critical content off gutter; no fake gutter bleed compensation in export	Bind-side behavior differs from outside edges; over-correcting here can distort layout intent
Interior text safety	0.5 in (13 mm) recommended	>= 0.5 in from trim on top/bottom/outside; additional gutter allowance for thick books	Gives tolerance buffer for trim movement and reader comfort
Cover bleed	0.125 in on all outer edges	0.125 in exactly; no manual template scaling	Cover trim drift is highly visible on solid backgrounds and frames
Cover text safety (front/back)	0.25 in recommended (templates may allow tighter)	>= 0.25 in from trim and >= 0.25 in from fold zones	Reduces chance of text crowding edges when cover wraps and folds
Spine safety if spine >= 0.35 in	Keep text clear of spine edges	>= 0.0625 in clearance each side of spine text block	Spine text remains legible when fold/lamination shifts
Spine safety if spine < 0.35 in	Keep text minimal and centered	>= 0.03125 in each side (if spine text is permitted by setup)	Thin spines have less tolerance for registration drift
Spine text minimum pages	No spine text for perfect bound under 48 pages	Hard fail below threshold	Avoids unreadable or unstable spine labeling
Interior PDF page mode	Single-page pages, not printer spreads	Hard fail if spreads detected	Spread exports break ingest geometry and can trigger automatic rejection
Cover PDF type	Single-page full spread cover file	Hard fail if split cover pages uploaded	IngramSpark cover workflow expects one continuous spread
Barcode/quiet zone on cover	Keep required barcode region unobstructed	Explicit visual check against template barcode box	Missing quiet zone can cause downstream distribution scan problems

Table B: PDF resource and standards tolerances

Resource class	Platform expectation	Recommended QA threshold	Pass/fail action
PDF standard	PDF/X-1a:2001 or PDF/X-3:2002 accepted	Export directly to approved PDF/X profile	Fail if output intent or conformance flag is missing
Font embedding	All fonts embedded	100% embedded, zero substitute fonts	Fail if any font is unembedded or substituted
Image resolution (continuous tone)	Sufficient for print	Effective PPI near final size >= 300 preferred	Warn below 300; fail below 200 unless intentionally stylized
1-bit line art resolution	Sufficient for sharp edges	600-1200 PPI target for monochrome line work	Warn below 600 for technical diagrams
Transparency handling	Flattened or properly preserved per PDF/X workflow	No unexpected rasterization of small text/vector art	Fail if flattening introduces artifacting
Color intent consistency	Predictable print conversion	Consistent profile strategy across interior/cover assets	Warn on mixed unmanaged sources; fail on obvious profile corruption
Page box integrity	MediaBox/TrimBox/BleedBox coherent	Box values numerically match trim + bleed rules	Fail on dimension mismatch

Table C: Suggested severity model for automation

If you are building a scripted preflight validator, use a severity model so teams know which issues block release immediately.

Severity	Meaning	Example triggers	Required action
Blocker	Guaranteed reject or high-probability production defect	Wrong page size, missing bleed on bleed pages, spread export, missing fonts	Stop release; re-export source
Major	Might pass ingest but likely to print poorly	Text too close to trim, risky spine placement, low effective image PPI in key pages	Fix before submission
Minor	Acceptable with known tradeoff	Slightly aggressive but still compliant type safety, non-critical image softness	Product owner sign-off required
Info	Non-blocking metadata	Producer note, profile naming mismatch with equivalent values	Track only

Spine width calculation formula table

IngramSpark's template generator is the final authority for spine width. Still, an explicit formula is useful as a pre-check so layout and cover design are not started from wrong assumptions.

Use:

spine_width_in = page_count * caliper_in_per_page

Where:

• page_count is the final interior page count in the title setup
• caliper_in_per_page is paper thickness per page (inches), selected from your print option/paper class
• Result is in inches; convert to mm by multiplying by 25.4

If your internal documentation stores thickness as "per sheet" instead of "per page," convert first:

caliper_in_per_page = caliper_in_per_sheet / 2

Then apply the main formula.

Formula variable table

Variable	Definition	Unit	Validation rule
page_count	Final approved interior pages	pages	Must match title metadata and exported PDF page count exactly
caliper_in_per_page	Paper thickness per page for selected stock	inches/page	Must match current print option; do not reuse from prior edition
spine_width_in	Computed spine width used in planning	inches	Must be reconciled against latest generated template
spine_width_mm	Metric equivalent	mm	spine_width_in * 25.4

Worked spine calculations

Scenario	Inputs	Calculation	Output
Example 1: 240-page B&W book	page_count=240, caliper=0.00230 in/page	240 * 0.00230	0.552 in (14.02 mm)
Example 2: 320-page cream stock book	page_count=320, caliper=0.00250 in/page	320 * 0.00250	0.800 in (20.32 mm)
Example 3: 120-page premium stock book	page_count=120, caliper=0.00280 in/page	120 * 0.00280	0.336 in (8.53 mm)

Engineering notes:

• A one-step page-count change can shift spine centerline enough to misalign spine text. Any page-count change requires regenerating the cover template.
• Never manually stretch an old cover spread to "fit" a new spine width. Rebuild from source with updated guides.
• Thin spines magnify rounding errors; keep at least four decimal places in inches during calculation, then round only for display.

Paper type vs thickness table

The exact value used in production depends on your configured print option and IngramSpark's current manufacturing mapping. Use the table below as a planning aid for early layout estimates, then override with template-provided geometry for final files.

Paper category (planning label)	Typical use case	Typical caliper range (in/page)	Planning midpoint (in/page)	Effect on spine and cover planning
B&W standard white	Text-heavy novels, manuals	0.00220-0.00240	0.00230	Narrower spine; easier to keep front/back panel widths stable
B&W cream	Trade fiction and literary titles	0.00240-0.00260	0.00250	Moderate spine expansion vs standard white at same page count
B&W premium white	Higher-opacity interiors	0.00260-0.00290	0.00275	Thicker spine; higher chance spine text alignment drift if page count changes
Color standard	General photo/text color books	0.00250-0.00290	0.00270	Cover spread grows noticeably on long books
Color premium/heavy	Art/photo-forward products	0.00290-0.00340	0.00315	Largest spine growth; demands strict template refresh discipline

How to use this safely:

1. During concept stage, estimate spine using midpoint values.
2. At title setup freeze, replace midpoint with option-specific value from the generated template workflow.
3. If your team stores paper profiles in code or spreadsheets, version them by date and print option so stale values are traceable.

Common failure mode: teams update page count and keep the same paper label, but the print option actually changed between proof rounds. That silently changes caliper and breaks spine alignment even when page count is unchanged.

Bleed math examples

Bleed errors are usually arithmetic errors, not design errors. The safest approach is to calculate expected PDF page geometry before export, then verify it in Acrobat page boxes after export.

Example 1: Interior bleed page geometry (6 x 9 trim)

Given:

• trim width Tw = 6.000 in
• trim height Th = 9.000 in
• bleed b = 0.125 in
• IngramSpark interior bleed applies to top, bottom, outside only

Expected exported page size for a right-hand bleed page:

• width Pw = Tw + outside_bleed = 6.000 + 0.125 = 6.125 in
• height Ph = Th + top_bleed + bottom_bleed = 9.000 + 0.125 + 0.125 = 9.250 in

Target checks:

• TrimBox = 6.000 x 9.000 in
• BleedBox extends 0.125 in beyond trim on top/bottom/outside
• no critical text inside the outer 0.5 in safety region

Failure signatures:

• White sliver on outer edge after trim indicates missing/insufficient outside bleed.
• Content clipped at top often means trim was set correctly but BleedBox/export bleed was not.

Example 2: Interior non-bleed page geometry (6 x 9 trim)

Given non-bleed content:

• page art does not touch trim edges
• no bleed needed visually

Expected exported page size usually remains trim size:

• Pw = 6.000 in
• Ph = 9.000 in

QA checks:

• confirm no objects extend to trim unintentionally
• confirm master margins keep text at or beyond recommended safety zones

Failure signature:

• Decorative rule that appears to touch edge but has no bleed extension can be trimmed unevenly and look misregistered.

Example 3: Full cover spread math

Given:

• trim width per panel Tw = 6.000 in
• trim height Th = 9.000 in
• spine width Sw = 0.800 in
• bleed on all outer sides b = 0.125 in

Cover spread dimensions:

• cover width Cw = back + spine + front + left_bleed + right_bleed
• Cw = 6.000 + 0.800 + 6.000 + 0.125 + 0.125 = 13.050 in
• cover height Ch = Th + top_bleed + bottom_bleed
• Ch = 9.000 + 0.125 + 0.125 = 9.250 in

Spine centerline from left edge:

• left_panel = 6.000
• left_bleed = 0.125
• centerline = 0.125 + 6.000 + (0.800 / 2) = 6.525 in

QA checks:

• template overlay should show panel/fold lines matching exactly
• spine text frame centered on template spine, with required side clearances
• barcode zone remains unobstructed

Example 4: Bleed budget for framed cover designs

Framed designs (borders near edges) are high risk because normal manufacturing variance plus trim/fold tolerance can make one side visibly thicker.

If your visible frame inset is 0.300 in from trim, effective minimum visual margin under worst-case movement is:

• 0.300 - 0.0625 = 0.2375 in

If you additionally allow lamination/fold visual shift near hinge regions, practical perceived margin can fall lower. For symmetric frame aesthetics, use larger insets (often >= 0.375 in) unless brand standards require tighter borders.

Validator decision-tree logic explanation

When a validator reports "not print ready," teams lose time because they fix issues in random order. The tree below forces a stable triage order: geometry first, then document structure, then resources, then color/metadata.

Why this order works

• Geometry defects (wrong size, wrong boxes, wrong spread mode) cause immediate reject regardless of font or color correctness.
• Structure defects (page count mismatch, unexpected blank pages, wrong file type) can invalidate otherwise compliant assets.
• Resource defects (fonts/images/transparency) are meaningful only after geometry is valid.
• Metadata/profile cleanup should happen last; it rarely compensates for hard geometry errors.

Decision tree (human-readable)

1. Geometry gate

• Do page dimensions, trim, bleed, and spread mode match expected numeric values?
• If no: rebuild export settings from source and regenerate PDF.
• If yes: continue.

2. Template reconciliation gate (cover only)

• Does cover overlay align with current template including spine and barcode zones?
• If no: regenerate template for current page count/paper/binding and rebuild cover.
• If yes: continue.

3. Structure gate

• Is interior single-page PDF with correct page count and expected blanks?
• If no: repair pagination/export mode.
• If yes: continue.

4. Resource gate

• Are fonts embedded and image resolutions acceptable at placed scale?
• If no: re-export with corrected assets and embedding controls.
• If yes: continue.

5. PDF standard/color gate

• Does file pass required PDF/X profile with consistent output intent?
• If no: convert/export to valid PDF/X and re-check.
• If yes: continue.

6. Submission gate

• Upload only checksum-verified files that match audited outputs.

Tool-by-tool correction workflow

1. InDesign (source geometry control)

• Start with latest IngramSpark template package.
• Lock units and avoid scale-based shortcuts at export.
• Export single pages for interior; export one full spread for cover.
• Set bleed numerically; avoid manual drag-only bleed adjustments.

2. Acrobat Pro (compliance control)

• Run All tools -> Use print production -> Preflight.
• Validate PDF/X conformance profile.
• Confirm all fonts embedded and inspect MediaBox/TrimBox/BleedBox values.

3. Template overlay validation

• Overlay exported cover on template guide layer.
• Confirm panel widths, spine width, fold alignment, and barcode quiet zone.

4. Submission control

• Upload audited interior and cover only.
• Archive checksum, preflight report, and title settings snapshot together.

Why This Happens

IngramSpark Complete PDF Preflight Guide usually appears when the file exported from the source document no longer matches the production rules for print geometry, export settings, or platform validation rules. A late trim change, incorrect template, stale page count, or PDF export override can all create the mismatch that the platform detects at upload time.

How to Detect It

Review the validator message, compare the uploaded PDF against the final trim and export settings, and inspect the affected pages in preview. If the source values, exported PDF size, and platform settings do not agree, the mismatch will usually become visible before the file is re-uploaded.

How to Prevent It

Lock one production specification for trim, bleed, page count, and export settings before the final upload cycle. Re-run the relevant calculator or checker whenever the source file changes so IngramSpark Complete PDF Preflight Guide does not return in a later revision.

Summary

IngramSpark Complete PDF Preflight Guide is a production validation issue caused by a mismatch in print geometry, export settings, or platform validation rules. The fastest fix is to correct the source layout or export setting, regenerate the PDF, and verify the updated file before uploading again.
