ASCIIHexDecode similar to ASCII85Decode but less compact.

ASCII85Decode a filter used to put the stream into 7-bit ASCII.

There should be no large advantage in using a different format unless Creo is not using a suitable compression scheme. What is confusing is that PDF supports a great number of compression schemes for raster images, including JPEG and a method used byTIFF. One feature that Pro version does have is a 30 day Free Trial period it's on the above page. If one is strapped for cash, Acrobat Standard also has the option, though it doesn't appear on the version comparison:

It's so much more productive to teach them when using the same models they are working on, and you can't demonstrate editing/creating parts from a step file.

I was hoping to load the company laptop with all the robot files from last year and kit of parts files for training demos, how to and such. The PDF issue we can work around, the bigger issue is training. If there is a way to install the student edition without requiring admin access I'm all ears. No software installation is allowed, no exceptions. I would love to install the student edition on the company laptop, but unfortunately they have a very strict policy that keeps it fully locked down. I just know from experience at work the stock Creo PDF writer makes big files. I think the individual part drawing PDF's were much more reasonable in size. These worked best to communicate design concepts, but files are too large to email to a teacher to print. Large PDF files were from shaded robot assembly drawings with muliple views and sheets. At least where I work, it could simply never happen. Thanks everyone for the responses, it's really too bad as it seems entire unrealistic a company could or would try to outsource CAD work to schools.
