Which Lucinda font do you think this is? All Lucinda fonts I see in a Google Image search are nothing like this.
You're right, this does not OCR well. In fact, if you just crop out a part of it to remove other noise, say, 09:43 AM, even with lots of margin Tesseract isn't even finding anything it thinks looks like text in normal page segmentation. The best I got (for the cropped out time) was: 39:43 HH So 28% incorrect. The definition of the 'M' is quite eroded already which is not great.
