Watercolor with line drawing rendering- issues when exporting to pdf

[Charbonneau]

I primarily use watercolor renderings with the line drawing overlay and I often run into issues with the lines disappearing from the pdf when exported. I am currently using Interiors X13 but had this issue with X12 as well. I usually have multiple watercolor images on a layout and it will randomly remove portions of the line drawing when I export the layout to a pdf. The first image is how it looks on the layout page and the the second image is how it appears on the pdf page. I am running the software on a MacBook Pro and wonder if it is software glitch or some computer issue (lack of memory etc)

What printer do you use for the PDF export? Are you using the one native in Chief?

Yes, I use the "Chief Architect save as pdf"  option. Everything generally looks fine on the the preview screen but when the pdf generates there will be lines or areas missing. I do use the Mac Preview to view and print pdfs and I am aware there is a know issue with black boxes appearing instead of the images when printing so it wouldn't surprise me if this was also a Mac Preview issue.
