A sharp photo can look blocky in InDesign because the document window is displaying a lower-quality preview. Compare the original file and a deliberate PDF export before sharpening or regenerating the picture. A display change can improve the working view, but it cannot recover detail missing from the actual source.
Identify where the softness begins
Use three named views: the original image, the placed image in InDesign and the exported PDF. Inspect the same recognizable feature, such as the edge of a product label or a person's eye. Keep a record of the actual source filename so that an unrelated high-quality version does not become a misleading comparison.
Adobe explains that reduced display quality can make graphics appear pixelated in the layout and provides View > Display Performance > High Quality Display. It separately warns that pasting may provide preview data rather than a proper placed source. Adobe: Pixelated graphics in InDesign.
Change only the working preview
The following is a proposed diagnostic comparison, not a completed test. On a saved working document, record the current display setting and one problem detail. Change to High Quality Display, then inspect that same detail without replacing the photo, changing scale or applying sharpening.
If the working view improves while the source and exported PDF were already clear, the evidence supports a preview issue. If the exported PDF is also soft, continue investigating the actual placed file, links, scaling and export settings. Do not announce success merely because the editor now looks better.
Object-level display settings can complicate the comparison. If one image remains different from neighboring pictures, inspect that object's display state rather than repeatedly changing every document preference.
Keep image replacement as a separate decision
A layout assembled by pasting images from another application needs a source check. When appropriate, place the intended original file through the external application's supported workflow, retaining the approved framing. Then compare the new PDF with the previous one.
This is distinct from automatically buying a larger generation tier. If the intended full-size source already exists, resolving its placement may be the necessary step. If the source genuinely lacks detail at the planned reproduction size, a preview preference cannot fix that separate limitation.
Use a three-view acceptance record
| View | Record | Pass condition |
|---|---|---|
| Original | Exact file and selected detail | Adequate source detail |
| InDesign | Display mode and same detail | Usable working preview |
| Actual exported file | Required final clarity |
Pass when the accepted source is correctly placed, the working view is understood and the final output meets its intended viewing requirement. Fail if a screenshot of High Quality Display substitutes for checking the exported file, or if sharpening creates halos around an already correct source.
Imagild can supply an approved artwork file for placement. InDesign display performance and source-link management are external controls; changing them is not an Imagild generation feature.
