I can't stand PowerPoint files. Even the PDFs generated by PowerPoint are often garbage. We get quite a bit of work from Fort Sill as well as other military posts/bases in this region. They do love PowerPoint. And MS Word. It's rare we can take a PDF generated by either application and go straight into production. Usually we have to ask for other copies of the assets used in the document, such as better quality versions of photos embedded inside the document. We've re-created a lot of unit crests through the years. But we still get new ones to convert. I had a whole pile of them to convert recently for an interior signage project in the building of a field artillery training battalion. We made pretty good money on the job though.
Funny thing, when someone from Fort Sill (or another post) gives us better quality assets to use in a project they often have to bring a CD-R they burned to our shop in person. Most of these guys have
computer systems that will not allow anyone to plug a flash memory stick into a USB port. And they're pretty restricted on what they can email to other people. Obviously it's all about security.
