Ideogram 4.5 提示词：字标、海报与包装案例

TL;DR

• Ideogram 4.5 已在 HiAPI 上线，调用名为 ideogram-v4.5/text-to-image。打开 Ideogram 4.5，可用下面的品牌字标、活动海报、横幅和包装标签提示词开始生成。
• 每张价格：low $0.043、medium $0.086、high $0.3145。价格与档位。四组商业案例均使用 medium，下方另有三档交通信息图。
• 把必须出现的文字完整放进双引号；生成后逐字检查小字和模型额外添加的文案。接入方法见API 接入指南。

四组提示词与对应成图

下方链接只预填提示词。打开后仍需选择图注中的 image_size 与 quality；一次请求生成一张。更换品牌或活动信息时，同时修改引号里的主标题、副标题和按钮文字，避免保留示例中的日期或品牌。

品牌字标：NORTHWIND ROASTERS

A clean minimalist wordmark logo for a specialty coffee brand, the text "NORTHWIND ROASTERS" set in an elegant high-contrast serif, a small compass-rose icon integrated above the letter N, warm cream background, centered, flat vector-style design, generous negative space

image_size: "square" · quality: "medium" · $0.086/张。品牌名在画面中央，罗盘图形放在整段字标上方，没有贴在字母 N 上。底行的成立年份与说明文字是额外添加的内容，使用前需要核对。

活动海报：ECHO VALLEY FEST

A vertical concert poster for an indie music festival, large headline text "ECHO VALLEY FEST" across the top, below it two lines reading "AUGUST 14-16" and "RIVERSIDE PARK", retro 1970s psychedelic palette of orange, magenta and teal, layered sunburst background, bold condensed type, high detail

用这个提示词生成 →

image_size: "portrait_4_3" · quality: "medium" · $0.086/张。标题、日期和地点分别成行，底部另有乐队名单与入场信息。提示词没有指定这些额外内容，不能直接当成真实活动信息。

健身应用横幅：MOVE MORE.

A horizontal social media ad banner for a fitness app, left-aligned headline text "MOVE MORE." in heavy bold uppercase, a smaller line reading "Start your 7-day free trial", and a rounded call-to-action button with the text "GET THE APP", energetic gradient from lime green to deep blue, clean modern UI style

用这个提示词生成 →

image_size: "landscape_16_9" · quality: "medium" · $0.086/张。标题和试用说明在左侧，按钮在右侧。若用于自己的应用，须同步替换提示词里的试用期限和按钮文案。

辣椒酱标签：EMBER & ASH

A product label for a bottle of artisanal hot sauce, brand name "EMBER & ASH" in a vintage woodcut serif, product line "SMOKED HABANERO" below it, a small badge reading "SMALL BATCH - 150ML", kraft-paper texture background with charcoal and ember-orange ink, symmetrical layout

用这个提示词生成 →

image_size: "square_hd" · quality: "medium" · $0.086/张。主品牌名与产品名分成两层。圆形小标增加了提示词没有要求的字符，最下方也补了一行说明；印刷前应单独核对标签小字。

三档交通信息图：大标题与小段落要分别检查

下面三张均为 720 × 1280 的 PNG，使用相同的交通信息图提示词。原案例记录为同一 seed；这里不补写未记录的具体 seed 值。它们展示的是这组输出的差异，不能据此保证某个档位每次都会拼写正确。要尝试相同的竖版构图，请选择 image_size: "portrait_16_9"，再选择对应的 quality；这是试用建议，不补写为原图未记录的请求参数。

low · $0.043/张

A dense informational poster titled "CITY TRANSIT GUIDE" with three labeled columns headed "BUS", "METRO" and "TRAM", a short line of body text under each heading, clean Swiss grid layout, red and black ink on off-white paper, flat vector infographic style

用这个提示词生成 →

大标题和三列标题可辨，路线标记出现重复。

medium · $0.086/张

A dense informational poster titled "CITY TRANSIT GUIDE" with three labeled columns headed "BUS", "METRO" and "TRAM", a short line of body text under each heading, clean Swiss grid layout, red and black ink on off-white paper, flat vector infographic style

用这个提示词生成 →

三列说明和路线示意分别排列。仍需检查小字，不能把生成的交通描述当作真实路线资料。

high · $0.3145/张

A dense informational poster titled "CITY TRANSIT GUIDE" with three labeled columns headed "BUS", "METRO" and "TRAM", a short line of body text under each heading, clean Swiss grid layout, red and black ink on off-white paper, flat vector infographic style

用这个提示词生成 →

大标题和图标清楚，但正文段落出现明显的拼词错误。提高档位不能代替文字校对。

用 API 提交字标提示词

示例明确指定 quality: "medium"，每张 $0.086，num_images 为 1。enable_prompt_expansion 为 true 时允许扩展提示词；如果要评估扩展对文案的影响，可以单独改变这个字段再比较输出。下方 600 秒是示例程序的本地等待上限，不是模型耗时承诺；超时后保留 taskId 继续查，不要直接重复提交。

常见问题

可以指定任意像素宽高吗？

使用 image_size 的六个预设：square_hd、square、portrait_4_3、portrait_16_9、landscape_4_3、landscape_16_9。请求不接受单独的 width 和 height。

一次可以生成多张吗？

当前 num_images 只能为 1。需要多个候选时分别提交任务，每张按选定的 quality 计费。

如何修改已有图片里的字？

使用 ideogram-v4.5/image-to-image，参数和价格应按编辑模式选择，见参考图编辑案例与价格与档位。不要直接把文生图的价格和字段搬到编辑请求。

哪个档位能保证所有文字正确？

没有这样的保证。先核对引号里的文字，再检查模型额外添加的小字；正式活动信息和包装说明应逐字确认。

复制字标提示词，打开 Ideogram 4.5，选择 square 与 medium 开始。
