First, scanning resolution will have a great affect on the quality of a conversion. So, choose the right resolution. Keep in mind that, inferior result is guaranteed with poor quality scanning. Now where should your settings be?

Over 600 dpi is considered as a very high-resolution setting. With this you will have greater recognition a higher conversion time. But you will not have any have any noticeable increase in terms of recognition. On the other hand, below 150 dpi is considered as a low-resolution setting. This will result in poor conversion.

So, our recommendation is setting the scanner resolution at 300 dpi for optimal results.
