Standard Product

Standard images are produced with bitonal text and, if graphical elements are present (illustrations, photographs, etc.) they will be segmented within the TIFF in color or grayscale.

Processing includes automatic deskewing, despeckling, cropping, removal of specks and other artifacts outside the textblock, centering, automatic image segmentation and conversion of text to bitonal. Manual image segmentation and deskewing may also be needed.

Images are delivered as uncompressed TIFFs at 300 dpi. Files of text pages are small in size (<100K); files with graphics are larger, depending upon the size and density of the graphics.

OCR is highly accurate when applied to these images to produce fully-searchable PDFs, which are ideally suited for online viewing. Non-searchable PDFs can also be produced. Printing of reproductions from PDF also yields excellent results.

Resolution Options

Images may optionally be produced at native resolution or at 400 dpi or 600 dpi. Multiple sets of output, produced at different resolutions, may also be generated from the same original captured images.

Other Options

Images may be produced entirely in color or grayscale. Processing includes automatic deskewing, despeckling and cropping; manual deskewing and despeckling may also be done.

Images are delivered as uncompressed TIFFs or JPEG at 300 dpi. Files will be fairly large (1 MB to 15+ MB per page). These images can be used to produce fully-searchable PDFs, which would be suitable for online viewing from a quality perspective; file size may inhibit practicality. OCR can also be performed but printing is not recommended for images produced in this manner.
