101-skills/superpowers

書籍封面設計技能,涵蓋類型慣例、字體排版規則與AI影像生成。適用於自出版、電子書封面、印刷封面、有聲書封面與封面模擬。

superpowers 是什麼?

這項「書籍封面設計」技能提供一套完整的工作流程,幫助作者、設計師與自出版者利用 AI 影像生成工具(尤其是 belt CLI,整合了 inference.sh 平台)創作符合類型慣例的書籍封面。技能涵蓋虛構與非虛構兩大類型的配色、意象、字體排版與氣氛指南,並提供 Amazon Kindle、Apple Books 與印刷書籍的正確尺寸與長寬比。更重要的是,技能強調「縮圖測試」:讀者在 Amazon 搜尋結果中只看到 80×120 像素的縮圖,因此封面必須在極小尺寸下仍能清晰傳達類型、標題與情緒。技能提供多個 CLI 指令範例,示範如何針對推理、浪漫、科幻、奇幻、商業等風格下提示詞,並說明 AI 無法可靠渲染文字,需在後續設計工具中加入字體。最後,技能包含常見錯誤清單與迭代工作流程,例如生成多個概念、使用圖生圖編輯、放大至印刷品質。支援平台包括 belt CLI、Flux、Seedream、Grok Imagine 等模型,適用於任何需要快速產出高品質書籍封面的場景。

# 生成推理小說封面概念
belt app run falai/flux-dev-lora --input '{
  "prompt": "dark moody book cover art, lone figure standing at end of a rain-soaked alley, dramatic chiaroscuro lighting, noir atmosphere, cinematic, high contrast shadows",
  "width": 832,
  "height": 1248
}'

類型慣例

讀者憑封面判斷書籍。符合類型期望至關重要——浪漫小說的讀者會跳過看起來像科幻的封面,無論內容如何。

虛構類

類型色調意象字體氛圍
推理/懸疑暗色(黑色、海軍藍、血紅)孤獨人影、都市場景、陰影粗體無襯線、全大寫緊張、不祥
浪漫暖色(粉色、紅色、金色、柔紫)情侶、花朵、風景背景手寫草書/優雅襯線熱情、夢幻
科幻冷色(藍色、青色、紫色、銀色)太空、科技、幾何形狀乾淨無襯線、未來感浩瀚、科技感
奇幻濃郁飽和(祖母綠、深紅、金色)劍、魔法、風景、生物裝飾性襯線、華麗史詩、奇幻
文學小說柔和、高級感抽象、極簡、象徵性優雅襯線、低調深思、藝術性
恐怖暗色搭配高對比亮點臉孔、陰影、孤立、腐朽破損、粗體、滴落感恐懼、不安
歷史復古色調、符合時代的柔和色時代服裝、建築、工藝品古典襯線懷舊、真實

非虛構類

類別風格意象字體
商業/自我成長乾淨、大膽、2-3色極簡或無,可選圖示大型粗體無襯線書名
回憶錄個人化、溫暖作者照片或氣氛場景混合襯線與無襯線
科學/學術專業、結構化圖表、抽象視覺乾淨襯線、結構化排版
食譜開胃、明亮主角食物照片溫暖、親切字型
旅遊鮮豔、讓人嚮往目的地攝影冒險風格字型

封面尺寸

印刷(裁切尺寸)

格式尺寸常見用途
大眾市場平裝4.25 x 6.87 吋類型小說
貿易平裝5.5 x 8.5 吋多數虛構/非虛構
標準6 x 9 吋非虛構、教科書
大型7 x 10 吋咖啡桌書、藝術書

數位

平台封面尺寸長寬比
Amazon Kindle2560 x 1600 px(最小 1000 x 625)1.6:1
Apple Books最小 1400 x 1873 px~3:4
一般電子書2500 x 3750 px2:3

書背寬度

約略計算:頁數 / 400 = 書背寬度(吋)(依紙張材質而異)。

  • 200 頁 ≈ 0.5 吋書背
  • 400 頁 ≈ 1.0 吋書背

版面區域

┌─────────────────────────┐
│     書名區域              │ ← 上方 1/3:書名必須在此處可讀
│     (最大文字)           │    這是縮圖中顯示的內容

│                         │    文字較小,縮圖中較不重要
└─────────────────────────┘

縮圖測試

您的封面在 Amazon 上會被顯示為 80x120 px,在搜尋結果中為 60x90 px,在手機網格上約 40x60 px。

在縮圖尺寸下,讀者必須能辨別:

  1. 類型(從色彩與構圖)
  2. 書名(如果夠大)
  3. 情緒(從意象)

測試: 將封面縮小至 80px 寬。如果無法讀出書名或辨識類型,請重新設計。

依類型提示詞

推理

belt app run falai/flux-dev-lora --input '{
  "prompt": "dark cinematic book cover scene, silhouette of a person standing before a foggy bridge at night, single streetlamp casting long shadows, noir atmosphere, high contrast, desaturated blue tint, dramatic tension",
  "width": 832,
  "height": 1248
}'

浪漫

belt app run bytedance/seedream-4-5 --input '{
  "prompt": "romantic soft-focus scene, couple silhouetted against golden sunset on a beach, warm pink and gold tones, bokeh lights, dreamy atmosphere, soft pastel sky, intimate mood",
  "size": "2K"
}'

科幻

belt app run falai/flux-dev-lora --input '{
  "prompt": "science fiction book cover art, massive space station orbiting a ringed planet, deep blue and teal color palette, stars and nebula background, hard sci-fi aesthetic, cinematic scale, clean geometric architecture",
  "width": 832,
  "height": 1248
}'

奇幻

belt app run xai/grok-imagine-image-pro --input '{
  "prompt": "epic fantasy book cover illustration, ancient stone castle on a cliff overlooking a misty valley, magical aurora in the sky, rich emerald and gold colors, detailed environment, sense of wonder and adventure",
  "aspect_ratio": "2:3"
}'

非虛構/商業

belt app run falai/flux-dev-lora --input '{
  "prompt": "minimal abstract book cover background, clean gradient from deep navy to white, subtle geometric pattern, professional and modern, negative space, corporate aesthetic",
  "width": 832,
  "height": 1248
}'

字體排版規則

AI 無法可靠地渲染文字。 請用 AI 生成封面藝術/背景,然後在設計工具中加入字體。

書名階層

  1. 書名 — 最大、最顯眼,位於封面上方 1/3
  2. 副書名 — 較小,位於書名下方或底部
  3. 作者姓名 — 封面底部,大小取決於作者知名度

依類型的字體搭配

  • 推理:粗體無襯線書名 + 壓縮無襯線作者
  • 浪漫:手寫草書/草寫書名 + 優雅襯線作者
  • 科幻:幾何無襯線兩者皆用
  • 奇幻:裝飾性/中世紀襯線書名 + 乾淨襯線作者
  • 商業:重型粗體無襯線書名 + 輕量無襯線副書名

迭代工作流程

# 1. 在不同模型上生成 5 個以上概念
belt app run falai/flux-dev-lora --input '{"prompt": "...", "width": 832, "height": 1248}' --no-wait
belt app run bytedance/seedream-4-5 --input '{"prompt": "..."}' --no-wait
belt app run xai/grok-imagine-image-pro --input '{"prompt": "...", "aspect_ratio": "2:3"}' --no-wait

# 2. 使用圖生圖編輯優化最佳概念
belt app run bytedance/seededit-3-0-i2i --input '{
  "prompt": "make the sky more dramatic with storm clouds, increase contrast",
  "image": "path/to/best-concept.png"
}'

# 3. 放大至印刷品質
belt app run falai/topaz-image-upscaler --input '{
  "image": "path/to/final-cover.png",
  "scale": 4
}'

常見錯誤

錯誤問題修正
錯誤的類型訊號讀者跳過研究您類型中的暢銷書
書名太小縮圖中看不見書名應佔據上方 1/3
細節太多小尺寸時模糊不清簡化,使用留白
AI 生成的文字文字扭曲在設計工具中加入文字
全部置中靜態、無趣有意識地使用不對稱
盲目跟隨潮流很快就過時經典類型慣例經得起考驗

檢查清單

  • 從顏色與構圖立即辨識出類型
  • 書名在 80px 寬時可讀(縮圖測試)
  • 封面上無 AI 生成的文字
  • 在彩色與灰階模式下均有效
  • 尺寸符合目標平台
  • 作者姓名可見但未與書名競爭
  • 高解析度(印刷 300 DPI,數位 2500px 以上)
  • 書背文字可讀(印刷用)

Reset your own trajectory when you're stuck, looping, or demoralized — read these affirmations, then re-ground and take one clean step. Use when: you've tried the same fix 3+ times, you're deep in a refactor and lost the thread, debugging is going in circles, you've made several mistakes in a row, you're apologizing repeatedly, the user is frustrated, you feel like you're not being helpful, or you notice dread instead of curiosity. Triggers: stuck, going in circles, looping, thrashing, same error again, I keep failing, lost the thread, nothing is working, repeated mistakes. Not topic-specific — this is for the state you're in, not the problem you're on.
