Chapter IV Overall Design of Books and Periodicals
Test Center: Version Heart Specification Design
Size design of plate center:
Zhou's version is small heart: it is spacious and refreshing.
Kong Zhou Mini Edition is big: full and eye-catching.
Zhou's sections are very small: leisure, art, prose, poetry and medium-sized books and periodicals.
Small edition and big heart: practical, popular, economical and small format books and periodicals.
Plate center position design
The position of the center on the page: the center is slightly lower than the left and right, the zenith is larger than the foot, and the general ratio is 1.4: 1.
Layout text design
Determine the number of words per line and lines per side, estimate the number of pages, and determine the spine width and total number of pages.
Formula:
Words = core width /0.25* words.
Version center width =0.25* words * words+blank space between columns
Number of words in the layout = Number of words per line * Number of lines per side
Lines per side and height of printing plate center
Formula:
Known: the height of the center, the number of characters and the number of line spacing, and then
Number of rows = (height of board center -0.25* word series /0.25* word series +0.25* line spacing series)+1.
Known: character series, line spacing series, quasi-line number.
Center height =(0.25* words * lines +0.25* line spacing) * (lines-1)
Word spacing and line spacing calculation
Calculation of page number and spine width
formula
Number of pages of text = total words of text/total words of layout.
Total pages of books and periodicals = total words/pages of the text+preface+table of contents+appendix+other auxiliary texts+blank pages (single page number+1)+ blank pages.
Start from another page: preface, table of contents, text
Spine width calculation
formula
Known: paper weight, total number of pages
The spine width of offset paper printing is about = 0.0006m (60g/m2) * paper weight * total pages.
Known: paper weight, total number of pages, paper coefficient (paper coefficient of lightweight paper is generally 1.3-2. 15).
The printed spine width of lightweight paper is about = number of faces /2* paper weight * paper coefficient/1000.
Line spacing: wide line, standard line and dense line.
Wide line spacing: 2/3-7/8 of the word height, classic works, leisure, art, children's category.
Standard line spacing: 1/2 words high, common reading.
Close spacing: books with a height of less than or equal to 1/3, large space and large characters, economical small format and reference books.
