选择成品类型和尺寸，查看页面如何拼版、折叠和裁切，确认出血与安全区，了解平面稿如何变成印刷成品。下方提供常见印前检查提示。How a printed sheet becomes an object: pick a product and a size, then see how its pages are imposed on the press sheet, where it folds and cuts, where the bleed and safe area are, and run a preflight check.

裁切线Trim

检查项参考常见印厂要求，具体规格以承印方为准。爬移（creep）指折叠套入的内层纸张因厚度而向外突出；这里按“（纸张数 − 1）× 纸厚”估算，纸厚由克重粗略换算，制作前宜用实测值确认。Checks follow common print-shop requirements; your shop's own spec wins. Creep is estimated as (sheets − 1) × caliper, with caliper roughly derived from paper weight; measure your stock if you can.

8 页小册子采用常见的单张纸折叠拼版。三折页的内折页通常略窄，具体缩减尺寸以印厂要求为准。The 8-page mini zine follows the common one-sheet fold; the narrower inside flap of a tri-fold is common practice, with exact values set by the print shop.
