Printing from Mac Preview and black boxes are showing up

Anonymous

We are having some printing issues and we are trying to track down the source. Since the PDF is created autocad i thought we should start there. 

We are using a MAC with the latest software update. We are using autocad LT 2019. 

We are printing DWGtoPDF

When we print from the MAC preview we get black boxes around dimensions, wipe-outs and hatching.  If we print the same PDF from adobe reader the black boxes are not there. 

 

Anyone else having this issue?

Hi Joshua,

>>>>Anyone else having this issue?
Yes.

There is a bug in Preview app (in macOS High Sierra and later releases) which resulted in black areas on hard copy, when you print PDF files created in AutoCAD with solid hatches with transparency.

When AutoCAD creates PDF with its build-in PDF "printers" from drawing with such solid fills, it creates raster image with transparency areas. Such areas are invisible in PDF, but they exist and Preview app prints them as black areas.

Workaround is to print using Adobe Reader or other application which doesn't use macOS PDF engine. Or convert PDF to raster image before printing.

We are also seeing this in SketchUp Layout PDFs. Our .png Logo prints with a black background but no black exists in the file. Have you seen if MAC is working on the preview bug? It's really annoying.

No.

Just yesterday I ran into this macOS (Preview app) bug when printing PDF document with PNG images with transparent background.
