Hi,

so I need to convert to PDFx for printing and every time I convert from PDF to PDFx (of any type) I get compression on the photos. I have tried turning the PNG up to maximum but that doesnt work. Ideally I would like to convert from the original 4 word documents (combined to make one PDF due to size) to the PDFx to avoid loss through another step but I have no idea how to do that.

The current PDF that I am trying to convert was saved from word with 330 DPI so the quality drop is minimal between WORD doc and PDF, but PDF to PDFx causes a noticeable quality drop in the photos. 

 

Please help! I cant figure out how to stop the compression and ive been googling for 2 straight days!

Since you are probably using a CMYK PDF images must be converted, since you made them in RGB. What is the quality loss you are seeing? Pixelation, colour shift, something else? Before and after screen shot may help.

I agree, it looks like pixellation. Now it would be useful

1. Can you share a problem PDF, both "before" and "after". The simpler the better, a PDF and PDF/X containing just this image would be fine.

2. How do you convert to PDF/X? And what version of Acrobat (not "latest" please)

This pixelation is due to the downsampling of the images, it is not due to the compression.
