How to arrange illustrations with text in book printing and typesetting.
(1) Generally, the main text transitions from one page to the next, adhering to the principle of placing figures after the corresponding text. However, if this results in a disconnect between the figure and the main text, flexible adjustments are necessary—placing the figure before the related text, i.e., at the end of the upper page and the beginning of the lower page. In practical typesetting, when figures and their corresponding text are difficult to place closely, the following methods can be employed for flexible handling:
①When the main text reaches the bottom of the page and encounters an illustration, leaving no space on the same page, there will be a dilemma: if the illustration is typeset first, the main text will spill over to the next page; if the main text is typeset first, the illustration will spill over to the next page. In such cases, if the two pages are facing pages (even-numbered facing odd-numbered), meaning the illustration and main text can be viewed without flipping, they can be typeset consecutively. When transitioning from odd-numbered to even-numbered pages, efforts should be made to avoid excessive separation between illustrations and text.
Illustrations generally cannot span across sections. When an illustration spans sections, adjustments should be made. There are two particularly challenging scenarios: one is when the illustration cannot fit at the end of the current page. If placed on the next page, it may cause a section break. In such cases, the illustration should be positioned at the end of the current page, while the corresponding lines of text from the current section should be moved to the next page. The other scenario occurs when a running illustration is relatively long and includes a section title within the running text. This situation is typically difficult to resolve through alternative adjustments and can only be addressed by placing the section title at the location of the running text.
(2) When a section of the main text contains numerous illustrations, the layout must strictly follow the sequence of the figures. It is preferable to arrange multiple figures on the same page. If a page cannot accommodate all figures and a page break is necessary, some figures may be placed before the main text, while others are arranged after the text and on the following page.
(3) If there are many illustrations that are relatively concentrated and their width exceeds half of the text block, making it impossible to arrange them side by side, it is best to center-align the figures.
(4) When turning a page, the main text should be arranged first, followed by the figures. If two figures cannot be placed side by side in a single layout, they may be arranged horizontally.
