Question: I have been testing PdfCompressor with OCR, I OCR’d a RAW TIFF files and the results were good on the super accurate (not on the balanced). My colleague claims that you obtain better results when you OCR scanned documents with lower resolutions, I never heard of this. What can you tell me?

Answer: The lower DPI statement is not correct. The ideal DPI is 300 for good OCR accuracy. Also if the input file is a PDF try running the file in raster mode to see if you get better results.

If you would like to retest PdfCompressor, I have attached the link for the free trial below:
