PDF Standart 3:2002 not available in Publisher

[Uwe367]

Hi Folks,
I let Flyeralarm print my print media and they want PDF´s to have the standard PDF 3:2002, but this Standart is not available in the choose options.
My question now is whether it is absolutely necessary to use this standard and if so, when will it be implemented?

Found this explanation on the web, these are from an indesign PDF export document.

PDF/X-1a:2001: Both PDF/X-1a:2001 and PDF/X-3:2002 presets set Acrobat 4 compatibility which flattens a file’s transparency. (Therefore, if you choose either of these choices, be sure to visit the Advanced panel and select the High Resolution Transparency Flattener Preset to retain the quality of your type and vectors.) PDF/X-1a supports CMYK and spot colors but doesn’t allow color management. RGB images are converted to CMYK; CMYK values are preserved. Image resolution settings are the same as the Press Quality preset.

PDF/X-3:2002: This PDF/X preset is similar to PDF/X-1a except that it also supports embedded RGB profiles and color management. This standard is more widely used in Europe than in North America. Choose this option for color-managed environments where you expect the printer to optimize color reproduction for the specific printing environment.

PDF/X‑1a (2001 and 2003)

PDF/X‑1a requires all fonts to be embedded, the appropriate marks and bleeds to be specified, and color to appear as CMYK, spot colors, or both. Compliant files must contain information describing the printing condition for which they are prepared. PDF files created with PDF/X‑1a compliance can be opened in Acrobat 4.0 and Acrobat Reader 4.0 and later.

PDF/X‑1a uses PDF 1.3, downsamples color and grayscale images to 300 ppi and monochrome images to 1200 ppi, embeds subsets of all fonts, creates untagged PDFs, and flattens transparency using the High Resolution setting

PDF/A
The “A” stands for “Archive.” This standard is intended for the digital preservation of electronic documents, and prohibits features ill-suited to long time archiving.

PDF/X
The “X” stands for “Exchange.” This standard is intended to facilitate graphics exchange between clients and print providers. This would seem to be a good choice for commercial print, but unfortunately it features strict restrictions that may serve to frustrate less-technical designers. In addition, it forces color profiles and other data like “output intent” that may simply be discarded by your print provider. In short, don't use this unless it is specifically required by your print provider or prepress workflow.
