Many of us consider document scanning to be a simple, everyday activity, but there are many technical aspects behind the process that can affect the final result of our actions. In this guide, I will guide you through the scanning process – from the simplest to more advanced concepts that will allow you to create document scans of the highest possible quality. We will talk about issues such as choosing the scan color and file format.
As you read on, you will also learn about the options for storing scanned documents, including issues such as personal data protection and business process automation using OCR technology.
What are The Best File Formats for Storing Scans?
Document scans are incredibly useful in everyday office work, but it is important to store them in the right file formats to ensure the best quality and readability. Choosing the right file format can have a significant impact on the durability and ease of use of scanned documents. Therefore, it is worth considering which file formats are best for storing scans.
- PDF – The most commonly used file format for storing scans is PDF (Portable Document Format). This is a popular format known for its versatility and preserving the original look of the document. PDF is also easy to share and print, making it an ideal choice for storing document scans.
- JPEG – A common file format for scans is JPEG (Joint Photographic Experts Group). This is an image compression format that is often used to store photos and scanned documents. However, it is important to note that JPEG files can lose quality when saved and opened multiple times.
- TIFF – Another popular file format for storing scans is TIFF (Tagged Image File Format). This is a lossless image compression format that provides high-quality scans and preserves all the details of the document. TIFF is especially recommended for storing scans of documents with a lot of detail.
- PNG – For scanned documents that contain text and graphics, the PNG (Portable Network Graphics) file format may be a good choice. PNG is a lossless image compression format that preserves the quality of graphics and text, making it ideal for storing a variety of scanned documents.
How to Scan Documents
Scanning is one of the most common ways of sharing, transferring and storing various types of documents, graphics, illustrations, photos, etc. However, the document received is often too large or its quality is poor. During scanning, we have to choose a number of technical parameters that affect the quality and size of the file we receive – this is where a problem can arise if we are not sure what we really need.
Color or Black and White Document?
The basic question we need to answer is: color or black and white scan? Remember that when scanning in color, we get a much larger file than in the case of its black and white counterpart. Most business documents can be safely scanned in black and white, even if they originally contain colored elements (e.g. headers, charts or diagrams).
Of course, there are documents that should be scanned in color, because otherwise they will be illegible. The optimal solution may be to scan documents in shades of gray, which will increase the readability of the file while not taking up as much space (and therefore – generating lower costs).
File Format and Conversion
The choice of file format depends largely on whether you decide to scan documents in color or black and white.
For black and white documents to be converted to PDF, CCITT-G4 TIFF is most commonly used. TIFF is supported by most graphics programs and can be used on multiple platforms.
Choosing a format for color scans is more complicated and depends on the type of image being scanned. The format should be chosen to reduce the size of the image with minimal impact on quality. Screenshots and vector graphics are best saved as PNG files. Other images are compressed using JPEG or JPEG-2000.
Some image conversion systems use advanced software to improve quality or reduce file size. For example, Adobe Systems has several tools to optimize scanned documents; among them, ClearScan, which recognizes text and images during scanning and automatically converts the content.
Scan A Document for Editing
How to scan documents so they can be edited? It is necessary to use OCR (Optical Character Recognition) technology , which allows you to transform scans into editable text. This process starts with traditional scanning, using a scanner or even a mobile app. Document scans are usually saved as an image file, which is not editable. This is where OCR technology comes in. Once a document is scanned using an OCR-enabled tool, the image is analyzed and recognized. OCR then transforms the image into editable text, usually saving it as a Word document or PDF file.
It’s important to ensure good image quality when scanning documents – that is, good lighting, legible writing, and no distortion. It’s worth noting that some tools are better at recognizing text than others, so it’s worth testing a few different options to find the one that works best for your needs.
Choosing the Right Document Scanner
A document scanner has become a very important tool today, which can transform paper processes into streamlined digital workflows. Modern scanners offer advanced features that are designed to increase efficiency, improve accuracy and security. The good example is a the PDF scanner application such as SwifDoo PDF for Windows, which allows you to easily scan documents and photos to PDF format, and additionally automatically recognizes text. The application itself also includes features that make it easier to organize scanned files and edit them.
Problems and Solutions When Scanning Documents
Document scanning is an everyday occurrence in many companies. Although a document scanner is an essential tool, this process can encounter various problems. One of them is often insufficient scan quality. This may be due to incorrect scanner settings, low resolution or lighting problems. In such a case, it is necessary to adjust the device settings to the type of document – we scan text differently than photos.
Another problem is text distortion caused by creasing the document. Here, the solution is to carefully straighten the sheet of paper before scanning. Another problem may be difficulty in reading the scan by OCR software – here, scanning at the right resolution and contrast is key. Also remember to protect scanned documents from loss – creating backup copies is essential. How to scan documents? Choosing the right settings and carefully preparing the document for scanning is key.
In Summary
To achieve high quality digital files when scanning, it is important to select the right equipment and take several steps, such as setting the scanner resolution, choosing the right file format, or properly matching components. Additionally, it is worth considering what digital file format you will use and choosing the one most suitable for the given application. You should also remember about additional elements that affect scanning efficiency, such as processor performance, amount of RAM, or size of mass memory.
With all the above tips in mind, scanning documents in the highest quality should no longer be a problem.
