    Re: Custom PDF Settings...

    PDF/X-4 supports live transparency. I don't understand the post that implied otherwise.

      PDF exported from InDesign 5 or Illustrator 13 using the PDF/X-4 settings saves live transparency. No "ifs", "ands" or "buts" about it.

        Re: Custom PDF Settings...

        Hi everyone,

        Thanks for the ongoing conversations... the knowledge of people on this site always astounds me!! Its nice to get a variety of opinions though on how others are implementing ideas and the pros and cons for each.

        I think for now I'll stick to advising people to use the "Press Setting" and see how we go. Hey, that's what we have been doing for the last while anyway and no major issues have cropped up!!

        I will do some inhouse testing though with my own created jobs and see if I can develop a good set of rules to send out. I just fear though that if I do supply a PDF preset some customers are going to think that their job will print fine with us no matter what they include as long as they export to our setting!!

        Cheers, Tony

          Matt,

          I've thought about it again, and if High Quality Print IS NOT creating 4C black, but PDF/X-1a or Press Quality IS creating 4C blacks, it's OBVIOUS (just as I've said before) that Adobe's 'Preserve Numbers (Ignore Linked Profiles)' is NOT doing what it is saying, and color management is happening.

          I determined this long ago without ever going to PDF. And this is why I've said all along that I turn my color management policy for CMYK to Off for this reason - to make SURE that I'm not changing incoming CMYK numbers.

          How the hell is the usual operator going to know that there sRGB images (untagged) are getting assigned the wrong profile in Quark (or Adobe if using prepress defaults)? How the hell is the usual operator going to know that there CMYK numbers are changing when Adobe is telling them they are not (by the color management policy)? This is f'd up as a football bat.

            PDF 1.3 flattens transparency. PDF 1.4 and greater keeps tranparency. All PDF /X standards use PDF 1.3 except PDF/X-4:2007 which uses 1.4 and keeps transparency.

            We currently use custom PDF settings. I actually supply customers with our PPD, Quark Print Style, InDesign Print Preset and Acrobat Distiller Job Option.

              Not true. PDF/X-1:2001 and PDF/X-3:2001 use PDF v1.3. But PDF/X-1a:2003 and PDF/X-3:2003 use PDF v1.4. And now PDF/X-4 and X-5 should both be on PDF v1.4.

                You'll have to go through and look at what the PDF/X settings are and reconcile those with your observations.

                And people think *I'm* crazy...

                    Matt,

                    "You'll have to go through and look at what the PDF/X settings are and reconcile those with your observations."

                    I did. But the PDF/X settings aren't the problem I mentioned in my last email. But the PDF settings do show the problem.

                    The problem is that the 'Preserve Numbers (Ignore Linked Profiles)' does not do what it says. And by making a PDF with High Quality vs. PDF/X-1a, I can see that. Why? Because High Quality joboptions' 'Leave Color Unchanged' does just that, so one-color black type stays one-color black. But PDF/X-1a joboptions' 'Convert All to CMYK' CREATES four-color blacks when they were one-color blacks before. How? Because Adobe's 'Preserve Numbers (Ignore Linked Profiles)' is not doing as it says it does. If it did, then four-color blacks wouldn't be created from one-color blacks. Any differing CMYK profiles would be ignored (like the settings says) and not color managed (which they are getting converted or they wouldn't change CMYK numbers). No need for me to reconcile this any further. I knew beforehand about this problem (and have said so on the forums multiple times at least, and why I use CMYK color management policy Off, which keeps this problem from happening of four-color blacks getting created from one-color blacks). This is just another way to show the problem.

                    Screw the PDF settings. They just show the problem. The problem (as I said before and you obviously didn't get, or wouldn't have mentioned me having to look over the PDF settings again) is the CMYK color management policy not doing what it's name implies.

                    "And people think I'm crazy..."

                    OK. Never said you were or I wasn't. But OK.

                      Nope, pdf/x-1a:2003 was basically just an update to pdf/x-1a:2001 to support pdf v1.4. But that's basically all it did.

                        No Don, I got it and you never said that I was crazy. I wanted someone else to verify. And I wasn't particularly meaning you. I was trying to lead people down a path of discovery so that they could evaluate it for themselves.

                          Just to be clear, the export presets built into Adobe CS3 for PDF/X-4 uses PDF version 1.4, but the specification for PDF/X-4 allows up to PDF version 1.6 (Acrobat 7). If you want to create PDF/X-4 files that are PDF version 1.6 from Adobe CS3, then you need to create your own presets and use the built-in preflight in Acrobat, Pitstop, or some other tool to verify/make the PDF conform to PDF/X-4. That is the method we currently use.

                              The trouble with sending PDF settings to customers is getting them to use them. Personally I prefer the open file and the PDF with every job.

                                There is one thing that PDF will never compensate for and that is for people who don't know what they are doing. If you're fixing a PDF then you're only fixing the symptoms, not the cause. Get the open files along with your PDF's and you'll make fixing a lot of PDF's, much easier.
