Thank you very much for your speedy reply, Thomas! That's all very good news. There's no problem with training, or training data, we have lots to work with. The existing OCR engine (OmniPage) seems not to want to work with the old Irish script at all, so there's no existing output. Is there facility or necessity for training on multiple different typefaces, and keeping them in separate models? There exist different forms of this script, from different publishers etc.
I'll give OCRopus a try at home tonight, see if I can get it working on OS X. We're working on Windows here in the office (sadly), is there a plan for a Windows version?
