Treat an image-resolution report as a check of specified technical properties, not a verdict on visual usefulness. Confirm the file and placed dimensions behind the measurements, then inspect the final image for legibility and accuracy. A passing value cannot prove that labels are readable or that the illustration teaches the right relationship.
Identify the measurement being reported
Read the report's definition of resolution and determine whether it refers to a source file, an embedded image, or an image at its placed size. Those measurements can answer different questions. A large source image may have a different effective resolution after being enlarged in the layout.
Record the units, file version, and scope of the check. If the tool does not explain what it measured, investigate before changing the artwork. A number presented with a green status is useful only when the author understands the property and context that the status represents.
Match each finding to the actual placement
Locate the image in the manuscript and confirm its final dimensions. The same source file may appear as a small detail in one chapter and a large illustration in another. A report that names only the source asset can hide the fact that its placements have different production conditions.
Check crops and transformations as well. A tightly cropped portion may retain less useful detail than the complete source suggests. Keep the relationship between the original asset, the selected crop, and the placed figure visible when interpreting a warning or a pass.
Compare with current format requirements
Use the current KDP guidance for the intended format when deciding whether the measured value meets the relevant requirement. Preserve that source and its verification date with the production criteria. Do not assume that a tool's default threshold necessarily matches the edition being prepared.
If the report and the requirement appear to disagree, compare their definitions before attempting a fix. The tool may be measuring a different property or inspecting a different file. Increasing a number in an image's metadata does not automatically create additional visual detail or resolve an unsuitable source.
Inspect the image for information the report cannot judge
Read labels and examine fine details at the intended viewing size. A high-resolution image can still contain tiny lettering, weak contrast, or a cluttered composition. Those problems concern the reader's ability to understand the figure and require direct inspection.
Check the content itself against the manuscript and approved references. Resolution does not establish that a diagram is accurate, a caption points to the right object, or a generated image preserves the intended structure. Keep subject review separate from the technical measurement so neither is mistaken for the other.
Review any proposed repair in context
When an image fails the relevant requirement, identify the cause before choosing a remedy. A better source, a smaller placement, or a rebuilt figure may solve different problems. Do not assume that enlarging or resampling the same file will restore information that was never present.
Inspect the repaired figure in the complete page layout. Reducing its size may improve one technical value while making the labels harder to read. A useful correction satisfies the production requirement and preserves the teaching purpose, rather than optimizing a report at the expense of the reader.
Close the finding against the final export
Run the relevant check on the selected publication file and record which placements were inspected. Confirm that late changes have not replaced an approved image with an older variant or altered its dimensions. Preserve any remaining limitations in the review record.
Save the source assets, placement information, and resolution findings with the edition materials. Later revisions can then identify which figures require renewed inspection. The report becomes a traceable part of production review while the author retains responsibility for the visual meaning and usability of the book.
Frequently asked questions
Clear answers for this publishing decision.
Does a high resolution value guarantee readable labels?
No. Label size, contrast, spacing, and composition still need inspection at the final reading size. The measurement addresses one technical property of the image.
Can I fix a low-resolution image by changing its resolution metadata?
Changing a recorded value does not create missing detail. Diagnose the source and placement, then choose a remedy that improves the actual figure and meets the relevant requirement.
Should the report be checked again after layout changes?
Yes, when those changes affect image size, crop, source, or export treatment. The previous result applies to the version and placements that were actually inspected.
What must I check, disclose, and verify myself when AI helped produce the book?
Review facts, rights, and source material yourself, record which parts were AI-assisted or AI-generated so you can answer Amazon’s disclosure question accurately, and treat every automated check as a starting point rather than a verdict.
