For English, most of the times, preprocessing your images and using official traineddata will give better results than trying to do training.
For finetuning, ( https://tesseract-ocr.github.io/tessdoc/TrainingTesseract-4.00.html#fine-tuning-for-impact) what is recommended is using the existing training text and a new font, so that there are minimal changes to traineddata. Using your own training data will not give you good results. > train tesseract on my documents Use the Makefile based training from tesstrain repo.
