pdf converison with OCR

Postby frankAscent » Tue Mar 15, 2016 1:26 am

Hi,
Any experience with the 'Maximize Accuracy' vs 'Maximize performance' settings for the 'Advanced OCR Recognition Settings' for pdf generation? We want to use the Maximize Accuracy to ensure the best OCR result, but we are not sure how it would affect the performance. Does it affect performance at scan time or only the pdf generation itself?

We are today using pdf conversion with 'image only' for all documents that are scanned through our Kofax Capture installation.
Currently we are considering to enable the pdf conversion with 'text under image', and high OCR accuracy is one important factor for the decision.

Thanks Frank

The performance hit will be on the server side but it really doesn't seem like there's much of a hit for us using those settings (max accuracy, Kofax PDF, text under image, resolution: 300, JPEG: 75, no image compression). We run 3 virtual servers with two Kofax PDF services plus an export on each one and it rarely backs up. Of course it would all depend on how much you plan to throw at it. Our users typically do not make huge batches so that may help with processing. Most batches are in and back out of PDF within a minute or two.

And the delay with adding OCR will also depend on the quality of documents you send through so consider that as well.

Hi, and thanks for your answer, that was helpful!

We do not worry if we get some delay on the server side pdf generation, as long as the performance for the scan process is not affected.
Also I can see that your settings are pretty similar to what we are using. In addition we have enabled PDF/A setting



Thanks & Regards Frank
