Since installing Snow Leopard and updating to Vectorworks 2011 both old and new pdf files created via export pdf are causing various printing problems (I am using an A2 Epson Stylus Pro 3800) . It is only pdfs created via Vectorworks export pdf and opened in Adobe that are problematic - those opened in Preview or created via the print dialogue box or created from other programmes such as Photoshop are fine. Both Apple and Epson have both stated that in this case it must be a Vectorworks issue.
The main problem appears to occur if the sheet layer from which the pdf file is created contains a large imported Tiff file such as an OS map typically 24-bit around 700KB. In this case printing an A3 pdf file takes about 30 minutes during which my MacPro hangs and crawls to snail space and is unusable. Other minor problems of misprinting, of small imported tiff and jpg files such as logos etc, are occurring but without affecting the printing time. These items imported as PICT files are fine Anybody any ideas? Anybody having similar problems ?
