pdf transparency causing print artifacts

jdfnnl — Thu, 12 Feb 2026 20:34:53 GMT

I have having an issue with pdfs that have partial transparency when imported into AutoCAD. Although this transparency is not apparent when placed over the white background of a sheet in paperspace, the pdfs are still printed with noticeable artifacts that correspond to these transparent areas.

I would reprint/convert the PDFs to a new PDF without transparency.

does this mean I need adobe photoshop to convert the pdfs to a non-transparent format?

I looked at the pdf in Photoshop and it has only one layer but is apparently still placed over a transparent background.

If you have a pdf editor like Adobe Acrobat then you can open your pdf file using Acrobat and then flatten it before saving

I tried using photoshop to flatten the pdf into one background layer then save but autocad still recognizes the transparent parts .. maybe I just need to convert the pdf to a raster image.

I searched the Whisper Ceiling fan spec sheet. It comes in clear for me.
