Two common problems for authors’ submitted figures are low resolution and an image size too small. Our journals required that all figures to be shown in main text meet the following resolution and size requirements:
For B&W line art, B&W halftones/combo halftones, and color halftones set TIFF model as bitmap, grayscale and CMYK respectively.
How to meet the resolution requirements: If you have an existing low resolution image, you cannot fix the low resolution issue by simply increasing the resolution values in an image editing software (e.g., Photoshop) since adjusting the resolution field in the existing file does not create more dots per inch, but only decreasing image dimensions.An appropriate way of creating a high resolution image is to first create a new image file with its resolution set at the required value shown above, and its size (dimensions) not exceeding the size of a print page (7.5” x 9.8”, which is equivalent to 2250 x 2940 pixels for a 300 pixels/inch image).
General guidelines for creating images of acceptable quality (using Photoshop as an example):
