If you have ever tried to submit an article to a medical journal for publication, you know that one of the most common reasons for rejection is low-quality resolution images or figures. Most journals require a resolution of at least 300 dots per inch (dpi) both horizontally and vertically, while some prefer 720 dpi. In this post, we will show you how to improve the resolution of your images using a free software called GIMP.
To begin, right-click on the image and go to properties. You will see a lot of information about that particular image. If you go to details, it will show you the resolution of the image. If the resolution is below 300 dpi, it will not be accepted by most journals.
To increase the resolution of the image, you will need to use GIMP. Open the file in GIMP and go to Image > Print Size. Increase the resolution to 300 dpi or 720 dpi if required by the journal. Click the OK button to save the changes.
To save the file in the required TIF format, you will need to export the file. Click on Export and change the name of the file to something different to avoid overwriting the original file. Make sure that the file extension is .tif. If the file is too large, you can compress it to reduce the file size. Finally, click on the Export button to save the file.
To check the resolution of the new file, right-click on the file and go to Properties > Details. The horizontal and vertical resolutions should be at least 300 dpi.
By following these steps, you can increase the resolution of your images to meet the requirements of most medical journals. With higher quality images, your articles are more likely to be accepted for publication.
