In regards to what Test Screen Name is asking from you, that brings me to partially suggest some additional tweaks in your Windows 7 computer: You can (and should) create data collector sets through the performance monitor like shown here: https://www.computerperformance.co.uk/windows-7/data-collector-set/ https://www.thewindowsclub.com/how-to-use-perfmon-performance-monitor-windows And you can also use the same technique to activate all the cores in your processor plus increase your RAM as I found in two videos titled "Double Your Computer CPU Speed for Free" and "Double your Computer RAM for Free" posted by youtuber ThioJoe back in July 15, 2016 and March 23, 2016 respectively ----------------------------------------------------BREAK------------------------------------------------- On the other hand, I have very limited to no-experience in the tools that you are using, but I have to ask: Are you saying that you were able to use the Pitstop software to do the DXF file to PDF conversion and also open it and edit the converted PDF file with Pitstop and had no issues? OR, is it that when you open the same converted to PDF file with Adobe Acrobat you get the issue? What if an important step was missed while changing the preflight settings in your Pitstop software before the file is converted? So I went ahead and read a little more and I think I found the following links to be of interest: Here is an Adobe Help guide on removing page or object, resetting printer settings to defaults, combining fragmented images, merging/flattening layers, adjusting transparencies, changing Postscript option and error handling in Windows https://helpx.adobe.com/acrobat/kb/printing-complex-pdfs-acrobat.html This link on how to set andvanced printing options and the next one on how to troubleshoot Postscript errors: https://helpx.adobe.com/acrobat/using/advanced-pdf-print-settings.html https://helpx.adobe.com/x-productkb/global/troubleshoot-postscript-errors.html This last two are a little redundant, but I am linking them here if other members of the community are reading and want to learn some basics about the CAD environment you are using: https://www.piworld.com/article/rips-directing-imagesetter-16778/all/ https://www.dalesway.co.uk/blog/benefits-of-using-a-screen-printing-rip/
