CMYK color space VS PDF/A-1b

Aspose.Words Product Family
1

I got the requirement to have any pictures in my PDF in a CMYK color space.

When saving a pdf with PDF/A-1b and CMYK color setting, the document doesn’t seem to be valid PDF/A-1b: Checking with Apache PdfBox I get the following error: “Invalid Color space, DestOutputProfile isn’t CMYK ColorSpace”

PdfSaveOptions example:

PdfSaveOptions pdfSaveOptions = new PdfSaveOptions();
pdfSaveOptions.setCompliance(PdfCompliance.PDF_A_1_B);
pdfSaveOptions.setImageColorSpaceExportMode(PdfImageColorSpaceExportMode.SIMPLE_CMYK);

Please advice how we can generate a PDF/A-1b compatible PDF with CMYK?

Yes, the problem persist. Please find attached: Example docx, resulting pdf and the report generated by adobe acrobat reader.

The code to reproduce it:

public static void main(String[] args) throws Exception {

    final Document nodes = new Document(“cmyk.docx”);
    final PdfSaveOptions pdfSaveOptions = new PdfSaveOptions();
    pdfSaveOptions.setCompliance(PdfCompliance.PDF_A_1_B);
    pdfSaveOptions.setImageColorSpaceExportMode(PdfImageColorSpaceExportMode.SIMPLE_CMYK);
    nodes.save("cmykxxx.pdf", pdfSaveOptions);
}

I know this may be a limitation of aspose - but how to fix it?
