Question details
The user needs to prevent Illustrator files from appearing pixelated after being exported to PDF from InDesign using the High Quality Print setting.
- Product
- Adobe InDesign
- Device & OS
- not provided
- Scenario
- Exporting client-ready PDFs from InDesign containing placed Illustrator files.
- Observed behavior
- Placed Illustrator files appear pixelated in the exported PDF despite printing correctly.
Ensure that your placed Illustrator files are actual vector artwork and not rasterized images, and verify that all links in your InDesign Links panel are updated and not missing.
Adjust PDF Export Presets and Downsampling
Change the PDF export settings to prevent InDesign from downsampling your high-quality vector graphics.
Even when using the 'High Quality Print' preset, InDesign may apply compression or downsampling to certain elements. Adjusting the compression settings ensures your vectors remain crisp.
Go to File > Export in InDesign, choose a location, select 'Adobe PDF (Print)' as the format, and click Save.
In the Export Adobe PDF dialog, change the Adobe PDF Preset at the top to 'Press Quality' or keep your current preset to modify it.
Navigate to the 'Compression' tab on the left sidebar. Under both 'Color Images' and 'Grayscale Images', change the setting from 'Bicubic Downsampling to' to 'Do Not Downsample'.
Click Export. Open the resulting PDF in a PDF viewer and zoom in to 100% or more to verify that the pixelation is gone.
Check Link Status and Display Performance
Ensure InDesign is referencing the high-resolution original file rather than a low-resolution preview.
Adjust Transparency Flattener and PDF/X Settings
Resolve pixelation caused by transparency effects flattening during the PDF export process.
Manage and View High-Quality PDFs with WPS Office
While design software handles complex page layouts, WPS Office provides a lightweight, comprehensive suite for your daily document and PDF needs. Easily view, edit, and annotate high-resolution PDFs without heavy software.
- 1. Download WPS Office: Install WPS Office for free from the official website to access the built-in PDF toolkit.
- 2. Open Your Exported PDF: Launch WPS PDF and open the file you exported from InDesign to verify the vector quality at high zoom levels.
- 3. Annotate and Share: Use the Comment tab to add highlights, text boxes, or markup before sending the client-ready PDF.
Frequently Asked Questions
Why do my vector graphics look pixelated in InDesign before exporting?
By default, InDesign uses a 'Typical Display' setting to save system memory and improve performance. This renders high-quality vectors as low-resolution previews on your screen. You can change this by going to View > Display Performance > High Quality Display.
Does the 'High Quality Print' preset always preserve vector quality?
Not always. If your vector file contains raster effects (like drop shadows) or if the document's transparency flattener settings are set to a lower resolution, the 'High Quality Print' preset might still cause pixelation. Using the PDF/X-4 standard is generally safer for preserving vectors and live transparency.
How can I tell if my Illustrator file is actually a vector?
Open the file in Adobe Illustrator and press Ctrl+Y (Windows) or Cmd+Y (Mac) to view the artwork in Outline mode. If you see clean paths and anchor points, it is a vector. If you only see a rectangular bounding box, the image is rasterized.
