PDF/X
★ PDF/X-1a: ★ CMYK + spot★ works★ no transparency, no layers
![Page 18: What is PDF/X-4? And how is it related to other PDF ... › ... › 7aefb497281dfec5499a3b8c6e10873d.pdfWhat is PDF/X-4? And how is it related to other PDF standards like PDF/A or](https://reader033.vdocuments.mx/reader033/viewer/2022060315/5f0bf0137e708231d432f54b/html5/thumbnails/18.jpg)
PDF/X
★ PDF/X-3: ★ CMYK + spot + ICC based color★ works, except
★ where workflows or users are not fully ICC enabled
★ where equipment is too old★ no transparency, no layers

PDF/X
★ PDF/X-4: ★ CMYK + spot + ICC based color★ allows transparency and layers★ works
★ very well if modern PDF RIPs are used★ printers without modern PDF RIPs
★ use flattening (not worse than PDF/X-1a)

A word about transparency...
★ flattening ★ destroys internal structure of PDF pages★ often makes PDFs extremely complex★ discards searchability★ impedes last minute edits
★ nobody can escape transparency★ use of transparency is rapidly growing★ modern workflows/RIPs required to cope
★ thus PDF/X-4 more adequate in the long run
