More often than I'd want to, I have to OCR considerable volumes of something that can be called "punched" text. It looks like this:
So far, I tried:
1. Training FineReader 15 on this, but the OCR result could not be improved to a level justifying further editing of the result.
2. Manipulating the image before OCR in graphics-editing software to improve the structure of the font for OCR. The things I used were a descreen filter in GIMP, converting to black&white, erosion in Corel PSP. All to no avail with this particular sample.
Has anyone come across this type of "font" and found a way to get a decent OCR result with it?
Thanks in advance for any suggestion!
