An output intent is created where necessary. Matching color profiles are created for device-dependent color spaces. The conversion process embeds missing fonts and optimizes them by forming subsets. There is also an option to carry out an analysis of the output document. Conversion to the highest possible level of conformity is then carried out with the aid of the result from the analysis. The 3-Heights® PDF to PDF/A Converter first analyzes the input file based on the level of conformity (Level A, B or U).
