Resolution issues with Photoshop CS2

Question

I work for a fashion wholesaler. I am currently in the process of completely a line list to sent out to our clients. The producer of our product has sent me their complied line list, but because we are the canadian distributor we have to edit the line list. I have gone through changing prices and images. I have saved the file the exact same way our the last girl (doing this job) would save the file (as a PDF 1a. 2001) and the image becomes pixellated when viewing in Reader. The original file is also a PDF. I have tried changing the resolution, saving the file different ways and nothing works. I even tried opening the file, not changing a thing, saving it, and opening it in reader to have the file pixelated. The original file is crystal clear when opened directly in reaer. I do not understand what I have done in order to cause such poor image quality. Any suggestions?

Answer 1

The OP probably has the suite that includes Acrobat and Photoshop. I believe only the images can be altered using the Photoshop Application. I don't know if this can be done in Elements. I've never done this which is why I didn't try to answer the OP directly.
Here's an article I found about editing PDFs in Arcrobat + Photoshop CS3...Photoshop CS3 steps are on Page 2.
