When it comes to the input path that documents follow, for many it’s as simple as scan, convert, save, but others require more complex work-flows. The good news is there are tools out there to perform even the most advanced work-flows you could imagine. The bad news, they are expensive. I’m here to tell you about a way of combining your scanner and data capture, OCR, and document conversion software to make more complex work-flows without the premium.
By using settings that come with most document scanners and the ability of most data capture, OCR, and document conversion products to utilize hot-folders ( watch folders ) you can create robust multi-step work-flows out of the box. What you need is a scanner that supports multiple destinations usually 9 or more. This is indicated by an LED on your document scanner which at the point of a batch scan allows you to pick a destination number. Second you will need all the software required to perform the conversions needed for final result. In our example we will want to be able to OCR, data capture, compress and archive.
Basically the task is to create a funnel for your documents and the end result is saved where you want final destination to be. If your scanner supports what is called duel-stream then you can be working with two funnels simultaneously making your work-flow all the more robust. The first part of the funnel is identifying the document type. Each of the 9 destinations on your scanner should be configured for one document type ( you may want it to be one destination per business process instead ). The configuration would include the scan settings, 300 DPI of course, and what folder the document will go in. This is just the staging folder for the next step. Lets assume that we setup destination 1 for invoices and our scanner supports duel-stream. We want the invoices when it’s all said and done to have one copy to saved in a search-able directory, where the file is both compressed and in PDF/A format. Then we want another copy of the same invoice to be data captured and put in a working directory for someone to review. Lets put it all together.
Destination one on the scanner is configured for invoices. The first copy of any invoice will be saved to a hot-folder that the PDF conversion utility is watching, the second copy will be scanned into a hot-folder that the data capture product is watching. Because these are hot folders, both copies are picked up instantly and processed by each application. Our requirement for the second copy was only to be data captured and exported to a working directory, so we have now completed it’s task. For the first copy we have more conversions to do. The PDF conversion utility saves the OCRed search-able PDF to a hot-folder for the compression utility, the compression utility compresses the PDF and saves it to a hot-folder for the archive utility, and FINALLY the archive utility saves the result in our final destination for all invoices. Below is a basic diagram of the work-flow we created for invoices ( destination 1 )
Scan >PDF Creation >Compression >Archive >Final Result
> Data Capture >Final Result
Although it may have been slightly difficult to read, hopefully it’s clear that above is just one work-flow getting the most out of the tools offered by both the document scanner and conversion software packages. Now you can proceed to program each other destination with different document types and their associated work-flows. Programmers and tech savvy individuals will be able to easily envision ways to add scripts to make the process even more robust with email notifications etc. This approach is not a replacement for advanced work-flows but a middle ground between no work-flow and very pricey work-flows.
