In general, PDF/X standards can be used in printformer to generate print data.
However, it is important to note that the standard with which the print file is to be created later must be compatible with the assets used in the template (PDF or EPS or SVG files) and any assigned page and article templates. (Otherwise no print file can be created later from a draft).
The print data is created analog to the background PDF stored in the template.
(The standard is automatically read from this and applied, no conversion is done in the printformer).
However, if no PDF/X standard (PDF/X: none) is set in the master template, both assets and page/article templates with (different) standards can be inserted or used.
Special aspects of using PDF- EPS- or SVG in image blocks
If PDFs are used (placed) as assets in the template, the inserted PDFs must have the same standard as the background PDF stored in the template. (Exception: PDFX/3: X1 also possible; PDF/X4: X1 and X3 also possible). PDFs without an X standard cannot be placed in the editor, regardless of which X standard is stored in the background PDF.
However, if the background PDF does not have a PDF/X standard there is no restriction on the PDFs placed in the editor.
EPS files can generally only be loaded as assets in templates with a background PDF without an X-standard and a compatibility of max. PDF 1.3.
(Since the EPS file format has largely been replaced by the PDF format, EPS files are converted in printformer to a PDF without standard.) We generally recommend against using EPS files, since the format is considered obsolete and is also no longer supported by other applications (e.g. Microsoft Office).
SVG (RGB color space)
If SVGs are to be placed as assets in the template, at least PDF 1.4 (X4) compatibility must be used for generating the print data (or the background PDF).
