How do I edit a PDF?

[bungiefan89]

Your post suggested that my advice was irrelevant, or at least less useful, because it doesn't have its roots in graphic design.

Let's address the "off-topic" part - where in the OP does he even mention graphic design? He asked why his graphics looked blocky; I gave him an answer that works for me. That's entirely ON-topic.

And again, nowhere in the OP is filesize mentioned as a concern, nor is printing. 600 dpi is an entirely workable format.

Again, we're not talking about graphic design, we're talking about making saved images less blocky. Go back to my reply to the OP (where I suggested using PNG instead of JPG).

Yikes! Alright, everyone let's calm down a little here.

Firstly, yes this is about Graphics Design (from my perspective), although I did not specify such a thing in my posts, so I don't fault anyone for any confusion there, although an argument about it seems rather unproductive.

Secondly, after trying 600 Pixels/Inch and 150 Pixels/Inch with PNG, I did not find any difference as the pictures displayed in InDesign. And this whole subject is a little redundant now as I am no longer making a pixel-perfect recreation of the PDF I was sent.

I am now taking a different approach to this project and just using InDesign to re-create the Newsletter as it's displayed in the PDF I received, but I will not do so with quite so much precision as researching how to edit a PDF file has taken up a significant chunk of the time I could have spent actually working.

I appreciate everyone's input on this subject, but for now I'm just going to continue re-creating the Newsletter as best I can using InDesign.

It never ends...

I really hate these internet p-ing contests. But, here goes.

Exactly.

Let's address the "off-topic" part - where in the OP does he even mention graphic design? He asked why his graphics looked blocky; I gave him an answer that works for me. That's entirely ON-topic.

Let's see, his third post? And I quote:

I've got to move some text around, change a logo, insert a new picture, replace some text with a picture, remove some 'filler' text... not a whole lot to do over all, but the work is varied.​

Sounds like graphic design to me.

nowhere in the OP is filesize mentioned as a concern, nor is printing. 600 dpi is an entirely workable format

You suggested the resolution. My concern is that the OP follows your advice. Workable is not the same as best practice. e.g., an average magazine cover will be about 18-24 Mbytes at 300 dpi. At 600 dpi, the image weighs 72-96 Mbytes, and 54-72 Mbytes of that data is thrown away at the RIP. It also takes 3-4 times longer to transmit, and 3-4 times as much space to store. Still seem "workable"?

...we're not talking about graphic design... ...I suggested using PNG instead of JPG.

I think we already determined that we ARE talking about graphic design. And yes, you suggested the switch to PNG, but for the wrong reason - because it "Seems to handle vector images better than JPG", which is erroneous - both are pixel-based formats and neither have any inherent ability to "handle vectors" better than the other - that's a function of the RIP software that creates the pixels in the first place.

I'm just trying to steer the OP in the right direction, not denigrate or belittle you. I hope you have learned something along the way. I'm sure if I had any questions about your particular expertise, you would be a great source of info, but please, let's remember what these forums are for?

Cheers,

I used Adobe Acrobat to edit PDF files before, but I think it's not so good.
