|PDF Standards (PDF/A/X)|
BCL ALLPDF Converter supports PDF creation of PDF/A-1b, PDF/X-1a and PDF/X-3 file formats. PDF/A, PDF/X-1a and PDF/X-3 are subsets or types of PDF. PDF/A is obtained by retaining the PDF features that are suited to long-term archiving, while PDF/X (PDF/X-1a and PDF/X-3) is created to facilitate graphics exchange. BCL ALLPDF Converter enables users to easily create 100% PDF/A/X compliant documents.
PDF/A-1b has the goal of reproducing the visual appearance of the original document accurately. PDF/A-1b falls under ISO 19005-1 Level B conformance which ensures that the rendered visual appearance of the file is reproducible over a long-term.
BCL ALLPDF Converter supports the following standards:
PDF/X file formats are a group of ISO standards for digital document exchange in PDF. The objective of PDF/X file format standards is to confirm that the content prints predictably, irrespective of the document type and the printing service provider. The standards are a subset of the Adobe PDF Specification 1.3.
We support the two most widely used PDF/X standards:
PDF/X-1a is a CMYK-based document format compatible with PDF-1.3. It requires that all font files used be embedded, and the document shall not be encrypted.
PDF/X-3 adds color management features to the PDF/X-1a standard.
If you are unsure about which PDF/X standard to use, you should ask your printing service provider. Generally speaking, currently PDF/X-1a is the most common format in North America. In Europe PDF/X-3 is the preferred choice on digital presses, but PDF/X-1a is commonly accepted as well.
Note that once you convert a PDF document to PDF/A/X, PDF/A/X will lose elements such as hyperlinks, bookmarks, metadata, etc.
CMYK Color Space
How this property behaves depends on whether PDF/A, PDF/X, or dual standard (both PDF/A and PDF/X) output is specified.
For PDF/A, the color space can be either RGB or CMYK. If no CMYK profile is specified, then "sRGB", the standard color space of the Internet, will be used. A CMYK profile must be explicitly specified in order to generate CMYK based PDF/A output.
For PDF/X, the color space is always CMYK. If no CMYK profile is specified, then a default will be chosen. For PDF/X-1a:2001, the default is "USWebCoatedSWOP" and for PDF/X-3:2002 it is "CoatedFOGRA27".
For dual standard output, the same rules as for PDF/X apply.
If the output is neither PDF/A nor PDF/X, then the color space will always be DeviceRGB and any CMYK profile specified here will be ignored.
Below is a list of the CMYK files:
