Automatic OCR & Multipage PDF Creation


DT Pixel Acuity and History Factory have teamed up to provide holistic digitization related services. Part of these services include the digitization of bound material such as books, newspapers, annual reports, and magazines. The digitization of bound material calls for particular considerations around the fact that any given capture is part of a larger whole (for example, one page in a book, or one leaf of a newspaper). In order to add additional value to the digitized collection, DT PA and History Factory are providing OCR services. Our automation has improved throughput and turnaround time while simultaneously increasing the accuracy of the image set and OCR.

OCR and Multi Page PDF Compilation

Previously DT PA used an outside vendor to facilitate the compilation of individual pages of an object into a PDF; these PDFs also serve as an excellent vehicle for the OCR. 

DT PA has now brought the PDF compilation and OCR services in house and added them to a fully automated pipeline. The immediate and obvious benefit is increased productivity, as the digital assets no longer have to be sent off-site (with an additional lag caused by the 3rd party vendor), but can be processed immediately after capture. A less obvious benefit is a significant increase in accuracy. In evaluating OCR vendors we’ve found a significant race-to-the-bottom in terms of the cost of the service provided, which seems to be driving an environment in which the quality of the OCR provided is assumed to be unimportant. We’ve found that simply by bringing OCR processing in-house, taking first-party responsibility for the results, and working off of a quality-first mentality, we’ve been able to greatly increase the consistency and accuracy of the OCR we are providing.


DT PA is dedicated to leading the industry in adopting new technology and new workflows wherever it will help us deliver on our primary tenets of maintaining preservation-grade FADGI 4-star image quality, conservation-friendly material handling, production that can scale to any size collection big or small, and customer-first work practices that make us a vendor you are genuinely thrilled to be working with. These two case studies exemplify the benefits of automation, but are just a sliver of the investments we are currently making.
