实战案例:用AI提示词制作精品冷萃咖啡液电商详情页24张视觉,原味生椰黑糖三系列统一风格(Flux)
发布时间:2026年10月08日 10:17:20以新锐咖啡品牌「昼刻CHOUK」冷萃咖啡液组合装天猫旗舰店上新为场景,演示如何用Flux(配合即梦做部分中文包装字样)三天产出24张详情页视觉:用一句话品牌基调「清晨窗光、白蜡木、琥珀色液体」统摄全页,建立瓶身锚点(25ml磨砂棕色小方瓶、黑色旋盖、系列色条标签)与三系列色彩编码(原味墨绿、生椰奶白、黑糖琥珀),先出一张主视觉定色卡再批量衍生;用微距冰滴入杯、3秒入水挂壁、冰杯拿铁三种场景图替代无法摆拍的棚拍,用对比图讲「浓缩液兑冰水/牛奶/气泡水」三种喝法。附食品类AI图高发问题:液体颜色与真实萃取度不符、标签文字乱码、冰块融化比例怪异、咖啡液与牛奶混合瞬间结块、三个系列包装互相串色、食品图过度诱食被平台判夸大等踩坑与合规边界(不写提神减脂功效、不暗示零糖黑糖产品无热量)。
背景
新锐咖啡品牌「昼刻CHOUK」要给冷萃咖啡液组合装(原味、生椰、黑糖三个系列,每系列8条、每条25ml)做天猫旗舰店上新。详情页需要24张视觉:主视觉1张、三系列包装特写各2张、原料与工艺5张、冲调场景6张、三喝法对比3张、礼盒与物流3张。传统食品棚拍报价3.2万,还要真实印刷的包装实物到位才能拍——而此时大货包装还在印厂,至少等12天,错过秋季上新窗口。
团队用Flux.1 Pro做主出图(材质与液体真实感最稳)、即梦补2张需要中文工艺字样的图,三天完成全部24张。事先整理的翻车清单:瓶身每一图形状都变、棕色方瓶变成透明圆瓶、标签上品牌名全是乱码、黑糖液画得像机油、生椰液白得像乳胶漆、咖啡倒进牛奶出现豆花状结块、冰块大得像玻璃砖、三系列标签颜色互相串门、食品图色泽油亮到平台审核认为夸大。定下三条铁律:先出一张「定海神针主视觉」锁死色板与光影,瓶身锚点用固定结构句复制粘贴,所有文字一律后期排版合成、绝不让模型生成中文。
第一步:定调,一张主视觉锁定全页视觉宪法
提示词
Premium e-commerce hero photography for a specialty cold-brew coffee concentrate brand, early morning soft window light from the left, a clean white-wax-oak tabletop beside a sheer-curtain window with faint bamboo shadows, three small 25ml frosted amber-brown square glass bottles standing in a neat front row with matte black screw caps, each bottle has a minimal wrap label distinguished only by a thin horizontal color band: deep forest green (original), coconut cream white (coconut latte), warm caramel amber (brown sugar); around the bottles: one clear glass of iced black coffee with a single black straw, a small ceramic cup of milk, two coffee cherries and roasted beans scattered sparsely, generous negative space on the right for Chinese headline layout, calm Japanese-minimalist mood, 35mm product photography, f4, realistic glass refraction, true-to-life coffee liquid color, no text no logo render
Negative: glossy plastic bottles, round bottles, visible brand letters, fake Chinese characters, oversaturated colors, neon light, cluttered table, dessert cake, steam, people
产出:首图重抽9次,锁定一套「视觉宪法」:窗光从左45度、色温4800K、背景米白+白蜡木、液体必须是通透的琥珀棕色而非死黑。这张图后续用吸管取色做成色板(瓶身棕#7A4A2E、墨绿#2E4A3A、椰白#F2EDE3、黑糖琥珀#B5762E),全页所有图在提示词里都附带同一组材质描述。先定调再批量是整个项目零返工的根本——前期同事提出「先各出各的最后再统一」,被否掉了,事实证明正确。
第二步:瓶身锚点结构句,三系列批量出图
提示词
[可复用瓶身结构句·原味]
one 25ml frosted amber-brown square glass bottle, sharp vertical edges, compact rectangular prism shape, matte black ribbed screw cap, a minimal paper wrap label in warm off-white with one thin deep forest green horizontal band, label area intentionally blank for later typography, photoreal product photography, soft left window light on white-wax-oak surface
[系列衍生·生椰]
……same 25ml frosted amber-brown square bottle, matte black cap, off-white label with one thin coconut-cream-white horizontal band; beside the bottle a small halved young coconut with clear coconut water droplets
[系列衍生·黑糖]
……same bottle shape and cap, off-white label with one thin warm caramel-amber band; beside the bottle two dark brown kokuto sugar cubes on a small wooden dish
统一参数:3:4竖构图,镜头90mm微距等效,f5.6,纯白到米白渐变背景可直接抠图,输出分辨率2K。
Negative统一追加:round bottle, transparent bottle, dropper cap, pump head, text, barcode, QR code, color band duplicated, two bands
产出:把瓶身描述做成一段固定英文结构句,24张图里凡是有瓶子的(17张)全部复制粘贴,只换色条与陪体。这解决了「瓶形每图漂移」的核心痛点;color band duplicated, two bands进Negative后,串色问题从约30%降到5%以下。标签上的中文品名、净含量、配料表全部由设计师在PS里后期排版——AI只负责生成留白标签,文字一次都不让模型写,食品包装最敏感的配料合规因此完全可控。
第三步:工艺与原料图,把「12小时低温冷萃」画出来
提示词
[低温慢萃,16:9横图]
Documentary-style coffee roastery still life at dawn, a large clear glass cold-drip tower with slow amber droplets falling one by one through a metal valve into a round glass flask below, next to it a small digital timer showing nothing readable and a clipboard (blank), brushed concrete wall background, warm pendant light, shallow depth of field focused on the falling droplet, realistic water tension and refraction, artisanal slow-coffee atmosphere, no readable text
[原料特写,3:4]
Extreme macro of medium-roasted Arabica coffee beans tumbling slowly from a burlap scoop onto a white-wax-oak table, beans with visible natural fissures and matte oily sheen (not wet), a few green unroasted beans at the corner for contrast, crisp morning side light, high detail food photography, natural color
Negative: burnt black beans, wet glossy beans, chocolate beans, berries mixed in, hands, text
产出:冷萃水滴塔重抽5次,前几次液柱连成水流不像「滴」——加上falling one by one与focused on the falling droplet后解决。原料图客户提供了真实产区与烘焙度信息(埃塞俄比亚耶加雪菲与云南保山拼配、中深烘),所以图中豆子色泽按客户寄来的实物照片校色,不凭空编造产地画面(比如拒绝生成埃塞高原农场图,因为品牌没有可核验的直接溯源故事,避免虚假宣传)。需要出现「12小时低温冷萃」字样的2张图改由即梦生成带空白标牌的场景,中文后期排版。
第四步:冲调瞬间与三喝法对比,液体物理最难
提示词
[3秒入水挂壁,9:16]
High-speed product photography moment: a thin stream of dark amber cold-brew concentrate being poured into a tall clear glass filled with clear water and three crystal-clear ice cubes, the concentrate sinking and forming natural amber swirl layers along the glass wall before mixing, realistic fluid dynamics, condensation droplets on glass exterior, bright clean kitchen background, white-wax-oak counter, morning light
Negative: coffee and water curdling, chunky texture, milk (this is water version), cloudy brown-gray water, oversized ice, glass overflowing, splashing outside
[拿铁混合,1:1方图]
A 25ml frosted amber-brown square bottle with black cap tipped over a clear glass of cold fresh whole milk, the last drops of concentrate hitting the milk surface creating gentle marbled brown-and-white ribbons, clean realistic mixing, no clumps, soft window light, minimal beige background
Negative: curdling, tofu-like chunks, gray dirty color, hot steam, cream foam overflow, text on bottle
产出:入水挂壁镜是全项目最难的一张,重抽12次。关键经验:先写清基底液体(glass filled with clear water),否则模型会自行脑补牛奶或可乐;混合瞬间必须显式禁止curdling, chunky texture——Flux默认把两种液体混合画成豆花状的概率奇高。冰拿铁图反而一次过,提示词里gentle marbled brown-and-white ribbons给了模型明确的良性混合目标。三喝法(兑冰水/兑牛奶/兑气泡水)最终做成同机位同光线三联图,杯子、冰块位置完全一致,只换基底,对比时视觉极其整齐。
第五步:场景图、礼盒图与合规审查
提示词
[办公场景,3:4]
Overhead lifestyle flat-lay on a light oak office desk in soft morning light: one glass of iced black coffee made from the small amber square concentrate bottle standing beside an open blank-notebook laptop (screen off, no text), wireless earbuds case, a plain beige tote, neatly arranged with breathing space, calm productive mood, realistic product photography
Negative: people, hands, brand logos on laptop, readable text, sugary pastries, donuts, exaggerated steam, neon
[礼盒与物流,3:4]
A premium matte kraft-paper gift box half open revealing 24 small amber-brown square bottles arranged in three neat rows separated by natural-color pulp trays, forest-green/coconut-white/caramel-amber color bands visible across the rows, recycled paper padding, beside it a sealed shipping carton with blank shipping label area, clean studio product shot, even soft light
Negative: plastic blister packaging, ribbon bow, luxury gold foil, wine bottles, juice boxes, addresses or barcodes
产出:办公场景刻意只放耳机、笔记本与帆布包,不放甜点、不在画面里出现「续命」「提神」字样暗示——法务给出的红线是:咖啡液属于普通食品,详情页禁止出现提神醒脑、减脂、消肿、护肝等功效暗示,也不得用「0糖0脂」概括黑糖款(黑糖系列含糖,需在规格表如实标注)。礼盒图的回收纸浆托与牛皮纸是真实包装方案,AI图按结构稿生成后再由美工替换正面的合规标签信息。最终24张图全部通过天猫食品类目审核,无一被退回。
成果与复盘
24张定稿从提示词首跑到交付用时三个工作日,生成成本(含重抽)约为棚拍报价的6%,详情页在大货包装到仓前两周即完成预热投放,收藏加购数据跑出后再决定三个系列的首批订货比例,降低了库存风险。客诉端未见「图文不符」——因为所有关键事实性信息(配料、糖含量、容量、保质期)全部使用后期排版的真实文字,AI图只负责氛围与质感。
三条核心复盘:第一,食品饮料类AI出图,液体物理是主战场,基底液体显式声明+curdling类Negative必备,冰块、挂壁、混合分层都要逐张写物理状态;第二,文字零生成、信息全排版,既是乱码解药也是合规解药;第三,不要让AI替品牌编故事,产地、工艺、功效只画已核实的内容,耶加雪菲可以有,「埃塞庄园直采」没有合同就不能有。
6条可复用清单
- 视觉宪法先行:全页先产1张主视觉,取色板、定光位与背景材质,之后每张图复用同一组材质句。
- 包装锚点结构句:瓶/罐/盒的形状、材质、颜色、盖型写成固定英文段落复制粘贴,只换色条与陪体。
- 文字零生成原则:标签、标牌、屏幕全部留白,中文品名与配料表后期排版,既防乱码又守住食品合规。
- 液体物理四件套:声明基底液体、描述混合目标形态(marbled ribbons)、禁止curdling/chunks、约束冰块尺寸与冷凝水。
- 三系列对比同机位:同杯同位同光只换内容物,三联图天生整齐,比逐张单独生成的转化表现更稳。
- 功效红线自查:普通食品不暗示提神减脂等功效,含糖口味不得标注0糖,产地工艺只呈现可核验事实。
