Image Sizes (DPI)

Danger Phoenix · 12 Aug 2014 at 10:38

I'm working on customer communications for a client, where we are designing emails, PDFs and prints (via a large scale supplier).

The print supplier has said they want all images in 600dpi to maintain the quality when they print, but this would then inflate the sizes of any PDFs we store.

I believe the generally used DPI for email is 96, but doesn't 600dpi seem overkill for print?

We are talking about printing logos and small adverts on A4 paper... nothing major really.

We will never go to A3 or A2 as these are customer letters... if anything we would go smaller to A5.

What is the difference between PPI and DPI?

We want to keep the size of PDF outputs to a minimum, so we are concerned that having a few 600dpi images in there will inflate the size.

The emails we send could be viewed on any device or even printed, so what DPI and PPI would we use for this?

I did some reading on DPI and PPI but still find it quite confusing
