The invention relates to artificial intelligence, and provides an OCR image sample generation method and device, a printing form verification method and device, equipment and a medium, and the methodcomprises the steps: receiving an image generation instruction, and obtaining an image sample; inputting the image sample into a preset font typesetting generation model, obtaining first annotation information by performing text detection and character recognition on the image sample, and obtaining a simulation result generated by reconstruction of the font typesetting generation model; inputtingthe image sample and the simulation image into a preset style synthesis model, extracting style features and content features by the style synthesis model, and generating a synthesis result by the style synthesis model; and obtaining an OCR image sample label, recording the synthesized image as an OCR image sample corresponding to the image sample, and associating the OCR image sample with the OCRimage sample label. In addition, the invention also relates to a blockchain technology, and the information can be stored in the blockchain node. According to the invention, the OCR image sample withthe same texture style as the image sample is automatically generated, and the sample label is automatically labeled.
