ConTeXt just typesets text, places graphics and runs graphic creation routines which have been grafted in to TeX as libraries. The only things which should result in pixel information are: - graphics --- you're in control of their settings when they're created - internal graphic creation --- at one point in time there were issues w/ transparency, but these were resolved AFAIR So, check your settings for any graphics you're placing, and for those which you are creating w/in ConTeXt. Neither of the tools you mentioned are suited for checking pre-press-readiness of a file. Multivalent has some facilities for validating a file: http://multivalent.sourceforge.net/ as does qpdf: http://qpdf.sourceforge.net/ There are free on-line tools: http://www.pdf-tools.com/pdf/validate-pdfa-online.aspx Lots of commercial options such as Adobe Acrobat, Enfocus PitStop, http://www.fixmyprintfile.com/, &c.
