MediaCheck compares a PDF reference and a sample pixel by pixel. This means security independent of the language, the font and the kind of content. It does not matter, if the data in the PDF file is a raster image or vector or text. We compare the resulting visual appearance of everything: text, images, line-art. This allows us to find deviations in text of any language and font, in codes of any kind, in drawings or in images. You can do artwork inspection and text inspection in one tool with one step.
