document glass造句

Some tips for improving the result are : scan at the highest resolution you can; make sure the document glass on your scanner is entirely clean; put a sheet of black paper behind the scan to minimise the transmission of light reflected off the back of the scanner shining back through the paper ( so you get a ghost of the text on the reverse surface of the page ); make sure the scanning software is using a loss-less image format ( like TIFF ), or if it must use JPEG make it use the least ( ideally no ) compression; experiment with contrast settings in the scan software ( the OCR program should be able to do this itself, but some don't do a good job ) .-- Talk 14 : 57, 18 February 2010 ( UTC)
