1. Font selection: Try to choose common and easy-to-read fonts, such as Arial, TimesNewRoman, Helvetica, etc. Avoid using too fancy or unusual fonts, because such fonts may not display properly on other computers.
2. Font size setting: The font size should be large enough for readers to see clearly. Generally speaking, the font size in the text should be between 10- 12, and the font size of the title and subtitle can be appropriately increased.
3. Font color: The font color should form a good contrast with the background color so that readers can see the text clearly. Generally speaking, black or dark blue fonts are the easiest to read on a white or light background.
4. Font style: In addition to general font styles (such as bold and italics), you should also pay attention to avoid using too many underscores and strikeouts, because these symbols may interfere with readers' reading.
5. Mark clearly: clearly mark the source and meaning of the text in the picture so that readers can understand it. At the same time, it is also necessary to avoid using too much text in the picture, so as not to interfere with the reader's understanding of the picture content.
6. Consistency: Throughout the paper, the consistency of font, size and color should be maintained so that readers can adapt and understand quickly.
7. Copyright: When using charts made by others, we should respect the copyright of the original author and quote and mark them correctly. If possible, you'd better make your own charts to avoid copyright issues.
Generally speaking, the selection and format setting of picture fonts in SCI papers should be clear, easy to read and professional, and attention should be paid to copyright issues.
