Export settings to save a psd to a print ready pdf

[jezjsa]

Hi all,
wondered if someone could help me?

I have been asked to create graphics for an exhibition panel.

The final artwork has to be full size at 65dpi.
I have created the psd file at 1/4 size at 300dpi which should be ok i believe (cmyk).

My question is this...
What settings should i have the pdf export set to to make sure the resulting pdf file is good enough for a printer to use???

Should i choose 'High Quality Print' or 'Press Quality' from the preset settings? And should i be doing anything else other than selecting one of these?

My flattened psd file is 293Mb/254Mb.
When i export as 'High Quality Print' the resulting pdf file size is only 25.9Mb.
And when i export as 'Press Quality' the resulting pdf file size is only 25.6Mb.

This seems way too small - or is this OK/normal???

Thanks in advance,
Jez

Hi
300dpi will make 75dpi print when blown up 4 times.
Save as Photoshop PDF. High Quality Print will be OK.

The file size reduction is normal.

tommy1957 is correct. 75ppi should be fine.
What I always do is contact the producer of the final item and ask what resolution they suggest.

It really depends on the producer, the material being used, the viewing distance, and a lot of other items.

If viewed from 10 feet, then even 40 or less ppi could be satisfactory. If viewed from 1 foot then 65 could be ok.

Always find out, before starting a job what the final product will be, how it will be used and who will manufacture it.

As a prepress provider for over 10 years this has been my working method.
