PdfSaveOptions pdfSaveOptionsA1B = new PdfSaveOptions();
pdfSaveOptionsA1B.setCompliance(PdfCompliance.PDF_A_1_B);
pdfSaveOptionsA1B.setImageCompression(PdfImageCompression.JPEG);
pdfSaveOptionsA1B.getDownsampleOptions().setDownsampleImages(false);
// Use JPEG compression at 50% quality to reduce file size
pdfSaveOptionsA1B.setJpegQuality(100);
pdfSaveOptionsA1B.setImageColorSpaceExportMode(PdfImageColorSpaceExportMode.SIMPLE_CMYK);

doc.save(getArtifactsDir() + "PdfSaveOptions.ImageCompression.PDF_A_1_B.pdf", pdfSaveOptionsA1B);
