Callas underpins Quark PDF/x-4 output

Callas has pointed out that the 2015 edition of QuarkXpress, expected to be released at the end of March complete with PDF/X-4 support, will use its pdfToolbox software to verify the PDF output, the same technology used in Adobe Acrobat.

Matthias Günther, Global Director of the Desktop Business Unit at Quark Software, explained: “QuarkXPress has long been able to export PDF files, including options to export using the PDF/X-1a and PDF/X-3 standards. We already use callas software’s technology to do so”

callas offers pdfToolbox as a software development kit (SDK) which Quark integrated into its software, allowing it to run in the background. When the user chooses to export a file in PDF/X format, QuarkXPress allows them to select from PDF/X-1a, PDF/X-3 and PDF/X-4. If they choose PDF/X-4, pdfToolbox then checks to ensure the new PDF/X-4 file really does meet the ISO standard. If it fails the test, perhaps because of specific elements within the file, the user will receive a notification to this effect. Otherwise, the result is a valid PDF/X-4 file, with all the advantages for further processing which the format brings.

PDF/X-4 offers features such as unflattened transparency, media-independent colours, and layering.
