If you’re a subscriber to our blog, you’d learn by now that PDF has various subsets available for different purposes. This has solved many industry issues such as large-scale printing, storage, viewing, and transfer. Another subset of PDF that can help many users with graphics exchange is called PDF/X. The ISO standard for PDF/X is ISO 15930 and specifications for this format include solutions for printing-related requirements. This ensures that the file is valid for professional printing.
What makes PDF/X special is not only its restrictions but also its special file identification that states what PDF/X version it is. With various PDF/X formats available, this identification will allow users to define the specific kind.
Different kinds of PDF/X standards
For every PDF/X version that has color-managed data, the graphics inserted in it also has their own color profile therefore if the file is conditioned for CMYK, every graphic may possibly be in RBG.
To ensure that the printing is accurate and has room for cutting errors, it is always recommended that the file be printed with “bleed.” This term is used for printing which basically means the area that goes beyond the edge where it will be cut and trimmed off. A BleedBox is required for bleed and must be larger than the TrimBox/ArtBox but smaller than the MediaBox. To define these three terms, MediaBox covers the size of the entire document. The ArtBox or the TrimBox meanwhile is the printable area.
Unfortunately, standard features in PDF such as forms, signatures, comments, sounds, and videos are not allowed in PDF/X. However, there are certain exemptions if it does not affect the rendering of the file. For instance, if comments or annotations are outside the BleedBox, annotations can therefore be used.
Since technology is also continuously updating, ISO is also developing further PDF/X with the new PDF/X-6. This will be based on PDF 2.0 and is expected to be the standard for new print production.
