Pictures are an important part of SCI papers, which can directly express data or ideas. Peer editors also pay great attention to the review of charts in the process of reviewing manuscripts, and sometimes they are even called back for revision many times.
Therefore, it is very important to learn high-quality cartography in the process of paper creation. To make high-quality pictures, the most basic thing is to carefully read the submission guide of the submission journals, and there are generally special parts that require pictures.
Image resolution is mainly for bitmaps. Most journals require a picture resolution of 300 ~ 1200 dpi. If it is too small, it may not be clear. If it is too big, it will take up more pages and waste resources.
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 a picture, and it cannot be higher than 20 cm.
According to the width classification, it can be divided into three types: semi-layout, the total width of the picture is 8 ~ 9cm；; 2/3 layout, the total width of the picture is12 ~15cm; Full layout, the total width of the picture is 17 ~ 19 cm.
