Requirements of Journals for Papers and Pictures

As the saying goes, a picture is worth a thousand words. High-quality SCI picture table is undoubtedly a plus item of the paper, which can greatly improve the quality of the paper. Generally speaking, I suggest that you first look at the specific requirements of the target journal for chart submission. After all, each journal has slightly different requirements for charts. Here, I will introduce some general rules and precautions of charts to help you avoid detours.

1. Whether the chart is placed in the text or uploaded separately. Most journals require text, pictures, forms and additional materials to be uploaded separately; Individual journals require text to be attached with forms, and pictures to be uploaded separately; Some journals require that charts be added at the end of the text.

2. Do magazines charge extra for color charts?

3. Copyright issues. If you quote a chart published by others or you before, you must obtain permission from the copyright owner (author and publisher) and explain the source and purpose of the chart.

4. Do journals advocate detailed requirements or concise requirements for character legends? Write (do you need to write abbreviations and drawings? Statistical differences, etc. , whether the description of the chart should be detailed, or reflected in the results, or omit the academic knowledge in the profession and write the picture points directly). It is best to refer to the description methods of illustrations in published literature.

5. Number of charts. Most journals do not require the number of charts, but Bian Xiao also meets the requirements of some journals that the total number of charts should not exceed 6. Before submitting a manuscript, you must make reasonable puzzles or delete unimportant charts as supplementary materials according to the requirements of the journal.

6. Picture format. General journals recommend authors to submit vector diagrams. Pictures can be submitted in the following formats:

(1) vector diagram format. eps，。 Ai,. pdf，。 svg，

(2).psd，。 tiff，。 jpeg，。 Png of bitmap. The photos inside. Tiff format is processed by PS and submitted in LZW format with lossless compression.

(3) There is no format influence to edit. ppt。

It is best to set the picture format to the vector picture format of. Tiff or ... Eps when converting a chart into a picture.

7. Picture size.

Publishing houses often use column typesetting, which is divided into left and right columns. There are three general typesetting formats. It is best not to leave white space around the picture, or leave little white space. Generally, there is no limit to the height of the picture, and it cannot be too high to exceed 20cm；; ; According to the width classification, it can be divided into three types:

(1) semi-layout. The total width of the picture is 8-9 cm,

(2)2/3 layout. The total width of the picture is 12- 15cm.

(3) the whole territory. The total width of the picture is 17- 19cm.

8. Picture color requirements. RGB (red, green and blue) is used for online publishing, and CMYK (cyan, magenta, yellow and CMY) is a common standard in the printing industry. If a periodical accepts paper publishing, it is generally required that the color mode be CMYK. At present, more and more journals accept pictures in RGB mode, and generally do not require authors to modify the color mode. If the article is printed in black and white mode, all pictures should be converted to gray mode for submission.

9. The font size of the picture. Most English annotations use the same font as journal texts, such as Arial, Times New Roman and Helvetica. The maximum font size on the chart should not exceed 14. Try to use 8- 12, and try to use less fonts below 6. The font size in the same picture should be as consistent as possible. If not, is there a requirement for the proportion of different fonts?

10. The labeling method of the picture, the letters of different small pictures of the same big picture are capitalized; Whether the letters are marked inside or outside the picture content.

1 1. Image resolution.

Color map or gray map with a resolution of 300 dpi.

Composite drawings, including pictures with labels or thin lines, require a resolution of 600 dpi.

Line drawing, black and white picture without intermediate color, resolution 1200 dpi or 600 dpi.

12. Picture takes up memory capacity. If the picture is too large, it will affect the upload speed. Some journals require the size of a single attachment. Generally, the size of a single picture cannot exceed 10M.

13. Follow the principle of unity. Try to align the pictures horizontally and vertically between different small pictures of the same big picture; Pictures of the same type keep the same specifications.

14. The thickness of the line is generally between 0.25- 1.5 lbs .. to avoid that the line is too thick to affect the appearance, or too thin to crack.

15. The legend parts of the X-axis and Y-axis of the histogram or bar chart shall not exceed the limit boundary parts on both sides of the X-axis and Y-axis boundaries.

16. The abbreviations, numbers, letters, symbols and different colors that appear for the first time in the picture are best described in detail in the legend.
