Next Technical tips Brightness, quality etc. when scanning?
When increasing brightness when scanning, there are some important considerations to keep in mind to ensure your scanned documents have the quality you want:
Document type and content:
Consider the type of document you are scanning. Text documents typically require less brightness than photos or images.
If your scanner has a preview feature, you can use it to check the effects of brightness adjustments on the scanned image before scanning.
Experiment with the settings:
For best results, we recommend experimenting with the brightness and contrast settings. Some scanners offer automatic settings that can be helpful.
Consider the purpose and intended use:
Think about what you want to use the scanned documents for. For example, if you are scanning documents for printing or archiving, you may need different brightness settings.
Make sure your scanner is properly calibrated to ensure accurate colors and brightness levels.

When scanning original documents, make sure that they are clean and free of dust and dirt, as these contaminants can affect the quality of the scan.
If necessary, you can use image editing software after scanning to further adjust brightness or make other corrections.
Remember to select the correct file format and quality for your scanned documents. For text documents, a medium to high quality PDF format is often sufficient.
Check the results:
After scanning, check the results on your computer screen to ensure the brightness meets your needs before saving or printing the scanned documents.
Documentation: If you frequently scan certain types of documents, consider the optimal settings to save time on future scans. By following these tips and adjusting the brightness to suit your needs and the content of the documents being scanned, you can ensure you get high-quality scans.
