How to ensure successful OCR scanning

In order to have usable scanned images for OCR, it is the scanning process that needs to be top notch. This is because; successful OCR is directly dependent of good quality scanned images. If you are about to carry out an OCR conversion project, then in order to make it successful, you have to focus on the OCR scanning part. OCR has become popular today because it makes the task of getting usable soft copies of hard copy documents easier. With the help of OCR, the time spent in typing out huge documents is saved. And it helps to quicken the entire procedure of work thereby leading to better efficiency. Given below are some tips in making the OCR successful.

Have a good idea of what is to be scanned

OCR conversion works for textual matter. The images and illustrations are not affected by it. But, if there are images in between the texts in the document to be converted, then post conversion, those areas will have gaps. So you will have to check for and adjust the coherence of the entire text. For this, you will have to know the documents well. When you do OCR scanning, take care of the areas where images, illustrations and graphs are there. Now that you know how they can affect the flow of your text during OCR, you can do the editing accordingly after the OCR is done. Knowing what is there in the document makes the task easier.

Create the right settings

It has been stressed upon numerous times that in order to have good quality OCR conversion; the OCR scanning images should be of high clarity. For this purpose, you have to set the right formatting settings. The most important point here is the resolution setting. Most of the unclear scanned images are due to wrong resolution levels. An average of 300 dpi is usually good for most of the documents. If you have black and white document, then a 200 dpi resolution will be okay. On the other hand, if the document to be scanned is heavy with colorful images, then you would need a high resolution of 400 dpi. Following this guide will help retain clarity of images. Also, you must choose the right format in which it is to be saved, or else the OCR conversion will not happen. The popular types are JPEG or PDF.

Have realistic expectation of accuracy

At the end of the day, OCR is automatic word processing. Even though it is very good and gives highly accurate results, it would be wrong to expect the accuracy to be as perfect as the hard copy of the text. After a clear OCR scanning, when you go for the conversion, expect some minute errors to be there in the soft copy of the document. This is why, it is necessary to go through the document and check it thoroughly for any missed part. This will ensure high quality of conversion and make the document highly usable.
