I received a project in pdf; the files are quite large and my client doesn't have the original files, additionally she told me to edit the files a little bit so I'd have to do a little bit of DTP.
1. You cannot do DTP on a PDF unless you have the original DTP format.
2. Exception: you can do emergency DTP on PDF if you have a powerful (read: expensive) PDF editor, but that is like editing an image.
3. Exception: you can do DTP on a PDF if you convert it to a very, very large JPG, then embed the JPG in a DTP file, and then do your DTP over it, and export to PDF again. I know this is possible because I've worked at a newspaper's advertising department and clients' own DTP departments tend to ignore crucial page make-up instructions and then the newspaper's graphic department has to fix it with 10 minutes to spare before it goes to print.
However, both methods #2 and #3 will introduce colour shifts that are often not visible on screen... only in print do you see the horrible effects of such editing.
I know that jpeg pixelizes the photos and that can create a problem.
Not if the JPG uses zero additional compression and if the JPG file is large enough. If you're in the printing business, you'll be fine with such size limits. I suspect you are not. I suspect the client thinks you are.
Some of the images on the pdf files are quite complex so I prefer to use the best quality possible without really creating huge files...
Unless you're printing high-resolution indoor posters or wallpaper advertisements, no-one will notice the difference between a good JPG and whatever else. For newspaper, magazines, hoardings/bill boards etc, JPG is good.
I would be using Adobe's screen-shot tool.
If you create images using a screen capture method, you're essentially creating BMP files (or similar, depending on your operating system) that have the same resolution as your screen, which is less than 100 DPI. Your capture tool then converts the BMP file to another format. Home-based printing works on between 300 and 600 DPI for printing, so even if your client is a mom-and-pop print house, your very best screen captures will look like utter cr&p on paper.
So my question is which format should I use?
For your situation? Notepad, and nothing else.
