为标题文字留出空间的旅行海报提示词

十条实测提示词,沿袭世纪中期与装饰艺术风格的旅行海报传统——登山缆车、白垩悬崖、峡谷公路、峡湾极光、夜行列车。每张卡片都附未经修饰的海报图、所用模型和价格,标题空间都已预留好。

01怎么写提示词

复古旅行海报的提示词该怎么写?

先放三样东西,再写场景。第一是传统:「mid-century screen-print travel poster」「1930s railway poster」「WPA national-park poster」「1920s art deco poster」是四种截然不同的视觉语言,点名其中一种,就能得到它的造型、它的风格化方式和它的印刷痕迹。第二是配色,限定数量并逐一列出:「limited palette of rust, ochre, dusty violet and cream」。第三是质感:「flat gouache colour blocks, subtle halftone grain, visible paper grain」让画面看起来是印出来的,而不是渲染出来的。然后才描述地方——「a red funicular carriage climbing a steep alpine slope, snow peaks layered behind in flat bands, pine forest in the foreground」。

第四句是大家最容易忘的:预留文字空间。这里每条提示词结尾都是「open sky band at the top and a clear strip at the bottom for typography」,外加一句明确的「no text, letters or numbers anywhere in the image」。让模型写出目的地名称,你得到的是扭曲的伪字母,怎么眯眼看都救不回来;让它把位置空出来,你得到的就是五分钟内就能排上真实字体的海报图。下面十张全部是在BananaBanana上生成的未经修饰的首次输出,其中四张每张只花了三美分。

能为真实的目的地做海报吗?

你能非常接近一个地方的感觉,同时离它的事实非常远。点名某座城市或地标,模型会自信地给你一个近似版本:大致轮廓对了,塔的数量错了,桥属于另一条河,山也漂移了几百公里。对于营造氛围的装饰画,或以情绪为重点的系列作品,这没问题——下面那张装饰艺术天际线正是如此:一座一看就是城市、却哪儿都不存在的城市。但对旅游局、目的地推广活动,或任何旅行者可能用来辨认地点的用途来说,这就不行了。

所以可行的做法是:提示词里写地貌,而不是地名——用「sheer dark cliffs falling into still black water with a cluster of lit wooden cabins on the shore」代替一个地名——再在排版时自己加上名字。这也能让你避开另一个陷阱:要求模仿某位在世插画师的风格。上面那些传统是宽泛的历史流派,而不是某个人的标志性风格;如果海报要拿去卖,这个区别很重要。

03技法

这些提示词为什么管用

点名海报传统

「1930s railway poster」「WPA national-park poster」和「1920s art deco poster」是三套不同的造型、配色和印刷痕迹。不写其中任何一种,你得到的只是一张普通的数码风景画,毫无那个年代的平面感。

限定并列出配色

「Limited palette of rust, ochre, dusty violet and cream」是让一组海报看起来像一个系列的关键。不加限定,每次生成都会自创一套配色,挂在一面墙上就散了。

预留文字带,永远别要求生成文字

每条提示词都以空白天空带、干净的底部条带和一句明确的「no text, letters or numbers」结尾。生成的字母扭曲得很明显,放到海报尺寸上一眼就能看出;用任意排版工具排真实字体只要五分钟。

写地貌,名字自己加

点名的地标生成出来总是大致不对。描述地形——悬崖、梯田、孤山、峡湾——再把目的地名称放进排版文字里,那里天然就是准确的。

06常见问题

旅行海报提示词,一一解答

怎么加上目的地名称?

用任意排版工具都行——Figma、Affinity、Canva、InDesign。放好海报图,把名称排在提示词预留的天空带里,底部条带再放一行小字。窄体几何无衬线字体或年代感的粗衬线字体都很配这种风格,整个系列几分钟就能换完标题。

打印要按什么尺寸生成?

凡是要打印的,都在Nano Banana 2或Pro上按2K生成。一张200 dpi的A2海报长边大约需要3300像素,所以2K再轻度放大,就能应付大多数家用打印和打印店的需求。Lite的1K适合社交媒体、缩略图和在几个概念之间做选择。

这样做出来的海报可以卖吗?

你在BananaBanana上生成的内容归你所有,所以原则上可以。两点提醒:不要要求模仿某位在世插画师的风格,也不要把编造的景色当作真实地点来呈现——按需印刷平台越来越多地要求你声明作品由AI生成,如实回答并不构成障碍。

怎样让一个系列保持统一?

固定传统、配色清单和质感这三句,只改场景。这三句就是系列的身份;每换一个目的地就重写一遍,做出来的十张海报就凑不成一套。

这里哪个模型最好?

平面、限色的插画是小模型最容易画好的东西,所以$0.03的Lite表现很稳——这里有三张就是Lite生成的。想要层次纵深和薄雾,升级到Nano Banana 2;带细腻丝网印刷颗粒和戏剧性透视的,比如极光、夜间站台和装饰艺术天际线,就用Pro。
