We use OCR to capture data from scans and create digital text automatically. As you probably know, OCR stands for optical character recognition. When you work with the digital file, you will always have constant values and the overall quality of the image will be good. You will benefit from optimal printing quality if you print the document. The sharpness and color accuracy always remains constant. Due to this, it does not matter how you work with your digital files. You should only focus on optical resolution. This means that the digital image, either created digitally or if it comes from a scanning, has a dpi optical value of 300DPI. The example we gave you refers to optical resolution. If you increase the print size, the elements will be less sharp and color accuracy will definitely decrease. To translate this better into human language, the optimal print size for that digital image is 87mm by 58mm. For example, if an image is 87mm by 58mm, which is roughly the size of a business card, and the same image has 1024 pixels by 680 pixels, the DPI value will be of 300. The more pixels or dots per inch, the sharper the image. If you don’t know this already, each digital image consists of a number of dots or as we call it, pixels.įor example, a 1024 pixels x 680 pixels image consists of 1024 dots on the long side and 680 on the short side. What does DPI mean or scanner resolution explainedĪs we said in the prior paragraph, the image resolution is calculated in DPI or dots per inch. Because of this, you can enlarge them much easier and with better printing results.īut let’s try and go into each aspect of this subject, and understand what is the scanning resolution and which one you should choose. Your images will be clearer, they will have much finer details. Practically, when you have more dots per inch, this will allow you to have better sharpness and color accuracy. In simple terms, the bigger the value the sharper your image will be. Scanning resolution is calculated in DPI or dots per inch. Have you ever had to scan something and wondered what scanning resolution you should choose?
