The second advantage of using PDF, is that all good PDF makers (export, distiller, or others) are able to downsample the pictures to eliminate all unuseful pixels and make lighter files, without the need of wasting much time to manually adjust exactly the resolution and size of each picture.
So, if you want files with text curved and pictures "as is", or if you are not able to handle PDF correctly, go back 15 years earlier and ask for EPS! or make another job...
From Indesign you can either export to pdf or make a postscript file then you can use Adobe distiller, sitting pdfx-1. If you are using Illustrator as design software, it is recommended to save as eps then use Adobe distiller as above mentioned.
I think that the PDF Format seems to be a unanimous response. I would ad that we began requiring our customers supply only PDF/X-1a:2001 format a few years ago and have reduced the majority of problems we used to have. I think it is the way to go, and since all major publishing software has the ability to export in this format, it is easy to teach your customers how to do it.
If the printer wants a distilled PDF, you better create a PS file and distill this PS file, but not an EPS.
It's better to make the PDF directly from Illustrator, with the "Save as PDF" command.
(and for a "ready to print" PDF, in most cases it's better to uncheck the option "Keep Illustrator editing fonction").
And for those who use Illustrator as a layout software (which it is not, so it's a very bad habit!!!), the "Save as PDF" fonction will also allow to output multi-pages PDF.

PDF x/1-a is the format of choice in our shop. Also look into enfocus instant pdf for your regular clients as a tool to help them create consistent pdfs everytime.
PDF/X-4 would be my choice now.
how about Postscript?many people say that postscript image better than pdf image..
This is more complicated than initially thought and depends largely on what process and RIP's your files will go through.
PDF with No compression, No downsampling, and embedded Font's is a good start.
Layer support can cause issues for some RIP's so its sometimes a good idea to send the source document as well.
Depending on who you are submitting to, they should be able to provide you with color management settings they prefer. Get them from the printer if you can.
As a generalization I turn color management off in Indesign and Acrobat, letting the RIP handle this based on the printers profiles
In this day and age there is really no longer a question on this.
PDF with embedded fonts is the only way to go
PDF -> Wikipedia the best standard for your shop, but x/1a is great!!
As said above PDF X/1-a and a quick glance with pitstop in order to check any client side errors... and ready to go
PDF is the optimal format for prepress, beacuse this is editable (eg. PitStop) and platform independent (PC, MAC, WIN, MacOS, Linux, etc).
But there are some important thing to know, and makes PDF:
- without ICC Profile
- with embedded font or outline fonts
- without OPI
- without low resolution images
- without RGB and LAB images
- without white overprint
And another important think is: DON'T USE the built in PDF generators from Illustrator or Indesign, USE Adobe Distiller to makes PDF files!
Pdf. We are trying to educate our customers how to do a perfect pdf. We offer support how to install our pdf output presets.
