Usually, the minimum resolution of pictures in papers is 300DPI, and some journals and magazines require no less than 600DP, and some magazines require 800DPI or even 65,438+0,200 dpi. The resolution required by periodicals and magazines refers to the resolution of the original picture, but the resolution of the modified picture after image processing usually fails to meet the requirements. Here are some key points in the process of drawing academic papers.

Inserted pictures are usually divided into two categories:

1. photo: usually a color map. This part of the photo with a resolution of not less than 300DPI is your first-hand information, and it may not be repeated after it is taken. Therefore, high definition must be done at the beginning (set to high resolution) to ensure the high resolution of the original image, and then it will be more convenient to process the image to avoid repeating the experiment because of poor image quality.

2. Generated graphics: generally, they are black-and-white and point-and-line graphics with a resolution of not less than 600DPI, mainly including various point line charts, bar charts, pie charts and various statistical charts. A professional drawing software sigmaplot is recommended here, which can satisfy any drawing generated by data, and the highest resolution of the original drawing reaches 1200DPI. Please refer to the software instructions or learn for yourself. Try not to draw with EXCEL, because the resolution of the original picture can't meet such high requirements. The graphic picture generated by data can be modified repeatedly, so the original data must be kept and can be modified at any time once there is a problem with the picture.
