提示词库 · 纹身设计
十个实测提示词，覆盖纹身师真正在做的那些风格——单针细线、美式传统、厚重黑work、点刺曼陀罗、水彩和日式刺青。每张卡片都展示未经修改的结果以及背后的模型。
先写风格，再写题材。光写「tattoo design」，你得到的是一张普通插画；写「American traditional tattoo flash, bold black outlines, limited palette of red, gold and sage」，你得到的是店里一眼就认得的东西。有效的结构是：「[style] tattoo flash design of [one subject with one or two details], [linework description], [color rule], centered on plain white paper」。关于线条的那一句最要紧——「single-needle fine line」「heavy solid black fill」「stippled dotwork shading」和「bold 3mm outlines」区分各种风格的作用，远大于题材本身。
要求flash图稿式的构图——白底居中的单个图案——而不是一个场景或一张照片。这是纹身师能读懂的格式，可以直接打印成参考页，也比带背景的渲染插画更容易转成转印稿。下面每个图稿都是它那条提示词在BananaBanana上未经修改的首次输出。用每张$0.03的Lite去试概念，等选定方向、需要线条干净到能交给纹身师时，再放到Nano Banana 2或Pro上重跑。
下面每张图片都是所在卡片提示词的未修输出——没有从几十次尝试里挑好的，也没有修图。模型徽标标明了它由什么生成、花了多少钱。
Single-needle fine-line tattoo flash design of a slender wildflower stem with three blooms and two curling leaves, drawn in hairline-thin continuous black strokes with no shading. Delicate minimal botanical style, centered on plain white paper, high contrast, nothing else in frame.
American traditional tattoo flash design of a swallow in flight carrying a rose branch, bold 3mm black outlines with solid color fill and classic whip shading. Limited vintage palette of brick red, mustard gold and sage green, centered on plain aged white paper.
Heavy blackwork tattoo flash design of a mountain range inside a thick circular frame, the sky rendered as solid black and the peaks as bold negative-space white shapes. Graphic high-contrast style with no grey tones, centered on plain white paper.
Geometric dotwork tattoo flash design of a symmetrical moth with its wings framed by thin triangles and concentric arcs, wing patterns built from graded stippling. Sacred-geometry aesthetic in black ink only, perfectly mirrored, centered on plain white paper.
Watercolor tattoo flash design of a hummingbird mid-hover over a thin black ink outline, loose translucent splashes of teal, magenta and amber bleeding beyond the linework with a few drip marks. Painterly abstract style, centered on plain white paper.
Dotwork tattoo flash design of a circular mandala with six concentric rings of petals and fine radial lines, shaded entirely with stippled dots that grow denser toward the center. Black ink only, perfectly symmetrical, centered on plain white paper.
Neo-traditional tattoo flash design of a fox head in three-quarter view wearing a crown of autumn leaves, framed by an ornamental art-nouveau border. Confident varied-weight outlines, rich saturated rust, teal and cream with smooth gradient shading, centered on plain white paper.
Japanese irezumi tattoo flash design of a koi fish swimming upward through stylized curling waves with a few maple leaves, drawn in traditional bold outlines with combed line shading. Deep indigo waves, orange and black koi, centered on plain white paper.
Minimalist tattoo flash design of an ocean wave drawn in one unbroken thin black line that curls into itself, small and compact enough for a wrist. No shading, no fill, generous white space around it, centered on plain white paper.
Close-up photograph of a healed fine-line tattoo on a forearm: a slender serpent coiling around the arm among small botanical sprigs, thin black linework with light stippled shading. Soft natural window light, shallow depth of field, neutral studio background.
「Blackwork」「neo-traditional」「irezumi」和「dotwork」各自带着一整套线条与用色的语法。开头点名其中一个，比堆多少题材细节都管用。
单针发丝线、3mm粗描边、点刺过渡、实心黑填充——正是这一句决定了图稿是能纹的，还是只是一张好看的画。
一个图案、居中、纯白、画面里别无他物。它能打印成参考页，转成转印稿也比渲染出来的场景干净得多。
选定图案后，再跑一条提示词，把它描述成已经愈合、拍在你想纹的那个部位上的纹身——在有人拿起纹身机之前，就能看出构图如何贴合身体曲面。
作为参考可以——今天的flash图集和Pinterest收藏板正是这么用的。要有心理准备，纹身师会重画一遍：线条粗细需要按部位调整，屏幕上看得清的细节必须放开，才能在皮肤下扛住多年。
粗实、留白充分的线条最经得起时间。细线和纤细的点刺刚纹好时很惊艳，但几年后会晕开，所以要和纹身师讨论线距和针号——你付钱买的正是这份判断。
是的，你在BananaBanana上生成的图片归你使用、打印，也可以带去纹身店。避免直接指名某位在世纹身师的作品，如果你打算卖flash图集，就把设计做成原创的。
像这些提示词那样在纯白底上生成黑墨图案，然后在任意编辑器里把对比度推到纯黑白。黑work、细线和点刺几乎可以直接转换；水彩和全彩作品则需要把轮廓重新描一遍。
$0.03的Lite非常适合在扁平黑墨风格里大量试概念。传统和新传统的彩色作品Nano Banana 2能胜任。对称要求苛刻的曼陀罗、点刺渐变和水彩晕染，$0.11的Pro值这个价。
