At first I thought your problem is that you left a frame around the words -
that IS a problem often - but I ran Tesseract on both images and got
perfect results both times. However, the app I am using (ScanBizCards)
resizes small images such as yours to around 1,024 x 768 and that's the
test I ran. Try upsizing your image with resampling to a larger size.
