How is the font and font size suitable for the layout design of sci-tech periodicals?

The font size in the text of sci-tech periodicals should be set within a certain range. Take Founder Fit software as an example. Journals with format of 16 often print their texts on the basis of No.5. In individual design, considering the aesthetics of the overall layout and the economy of layout space, small size 5 or 6 will also be adopted. However, because the words below size 6 are not easy to read, the words above size 4 and 6 are generally not used or simply considered as a decorative means. The font size between the title, introduction, text and illustrations should be reasonably arranged based on the principle of coordination, so as to distinguish different levels of information, prevent the confusion of the meaning of the text, and also create a sense of rhythm of the text on the publishing side. (2) Word spacing and line spacing have an important influence on the text layout and overall layout effect of layout design. Generally speaking, in sci-tech periodicals, the general typesetting software sets the text spacing to "0" mm by default, which can be consistent with the seriousness and scientificity of the text content, but sometimes in order to create a sense of rhythm and modernity in the layout, it is necessary to adjust the spacing of some words to obtain a visual effect with a strong sense of design. The setting of line spacing depends on the specific situation of the journal, which is generally between half and one word high. Words with small line spacing usually read less sparsely than words with large line spacing. But it plays a decisive role in saving layout space. Generally speaking, word spacing and line spacing are closely related. The general ratio of kerning to line spacing is 8: 10. Judging from the fluency and rigor of periodical reading, the line spacing must be greater than the word spacing, otherwise the text reading will be discontinuous, but the word spacing and line spacing are not absolute and should be determined according to the actual situation. In sci-tech periodicals, the design method of line spacing equal to or less than word spacing is rare. (3) The different arrangement forms are as follows: First, the periodical texts are arranged in this way, and the overall text form presents a sense of regularity and rigor, which is easy to read; The second is to arrange it in the middle, which is suitable for titles or short words. The arrangement in the middle can also form a solemn and classical feeling, which is a breakthrough compared with the neat arrangement around; Third, the left and right are not aligned, that is, each character is aligned with the next line based on the left side, and the right side is different according to the length of the text content, which is often used for one-sentence short messages, giving people a quick, natural and smooth feeling; Fourth, the left and right sides are uneven and freely arranged. These two forms are rarely used in sci-tech periodicals because they can produce unique personality effects. But according to the specific needs of different journals, sometimes this irregular arrangement can achieve a modern visual effect. In addition, there are many forms in the arrangement of titles. The same font size gradually increases or decreases, which can produce visual impact and speed; Font and font size are the same, but the horizontal or vertical position of each word is different, so it can be dynamic and active; Using different fonts for individual phrases can facilitate readers to break sentences and highlight the position of individual phrases or words in the whole sentence; Arranging characteristic fonts and designing fonts according to the characteristics of periodical columns or articles can not only break the traditional font program, but also enhance the characteristics of periodicals. Third, the matching of text colors Whether the matching of text colors in the layout is reasonable will directly affect the reader's mood. Proper color matching will bring strong visual impact to readers, while improper color matching will make readers impetuous. In scientific journals. The color collocation of the text is mainly reflected in the collocation of the title and the text, and some articles with weak academic nature have more color changes. (a) the same color with the same color refers to the first selection of a color, and then adjust its transparency and saturation, the color will fade or deepen, resulting in new colors, so that the text looks uniform in color, but there is no lack of layering. For example, the cover of No.6 issue of Practical Diagnosis and Treatment magazine in 2007, data, No.4 issue of Volume 33, Dan et al.: People in the layout design of sci-tech periodicals. 123. Select the font as the basic color, and other fonts are lightened or deepened on the basis of blue, so that the whole cover looks uniform; The cover of the fifth issue of Medical Clinical Research in 2009 is also based on blue, which divides the whole cover into three color blocks, but it also has harmonious beauty. (2) Adjacent colors Adjacent colors refer to adjacent colors on the color ring, such as green and blue, red and yellow, which are adjacent to each other. The use of adjacent colors can avoid the color confusion of the whole layout and easily achieve the effect of harmony and unity. For example, in 2007, the cover title of the Journal of Plant Nutrition and Fertilizer adopted the background color of blue with green. The emotional elements contained in green are consistent with botany studied in journals. Blue gives people a pure and rational feeling, and the combination of blue and green looks both unified and changeable.
