What should I do if scanned documents in TIFF format, which appear to be black and white, are still very large after being processed with PdfCompressor?
Sometimes scanned files are saved as color or greyscale files even though the actual document being scanned is black and white. We have seen this occur quite frequently using various capture devices including digital copiers and digital senders. While PdfCompressor in auto-segmentation mode can sometimes correct for this misleading image type, at least partially, it can often result in significantly larger file size. If the input document appears to be bitonal but the file size in TIFF format seems excessively large, e.g., exceeds 100 KB per page, there is a reasonable chance that these files are mapped as color or greyscale. To correct for this, go to the Image Processing page. In the Greyscale Images column, select the Remap images to bitonal option. Similarly, in the Color Images column, select the Remap images to bitonal option.
