PDF Output Workflow Conformance Test to the PDF/X-4 Standard (ISO 15930-7:2010)

In today's complex digital prepress environment, application settings and RIP settings can significantly affect the results of the printed materials. However, PDF workflow systems' compliance with PDF/X settings is questionable. Many workflows are still changing the critical properties of a PDF file. This is prohibited in the ISO-15930 because the result that the creator has seen and accepted in software or on a proof will be different from the final printed product if such changes are applied in a later stage. This study identified seven critical properties and to test them accordingly. Utilizing visual indicators and reference images for indicators of errors. The test reveals that all the issues tested are real-world issues, particularly in a print production environment.
