ИИ-мейкер обложек книг и альбомов с Krea 2

Обложка продаёт раньше, чем читают аннотацию. В сетке магазина, строке плейлиста или на ebook shelf первое решение почти всегда визуальное: это нужный жанр, нужное настроение, нужный quality tier? Поэтому обложки ломаются иначе, чем постеры или quote cards. Они должны выжить в postage-stamp scale и всё равно обещать мир.

Это book and album cover spoke в кластере Krea 2. Определение продукта и карта скоростных тиров — на what Krea 2 is. Грамматика промпта — в prompt guide. Здесь unique job — genre signaling, thumbnail survival и series continuity. Такое one-purpose split совпадает с helpful content guidance Google.

Ключевые выводы

• Обложки — сначала genre signals, потом illustrations.
• Книги обычно стартуют с 3:4; музыка — с 1:1.
• Thumbnail survival важнее fine micro-detail, который схлопывается в grid.
• Успех серии — locked light, style и composition, а не fresh lottery rolls.
• Reserve calm mass для title и author/artist type или планируйте type в layout software.
• Для campaign key art и caption cards используйте poster и quote guides; у covers другие tests.

Что обложка должна делать иначе

Book cover — front retail package: tall, title-forward, genre-coded, для shelf и online thumbnail parity. Album cover — streaming square: brand и mood first, series и discography continuity next.

Если кадр rich only when large — это concept art. Если still reads at 120 px wide — он начинает работать как cover.

Step 1: master crop для commercial surface

Стартуйте с поверхности, которая платит:

• 3:4 novels, ebooks, many paperback fronts, audiobook placeholders that stay tall
• 1:1 albums, singles, playlist art, streaming rows
• 9:16 promo stories and release announcements after the master exists
• 16:9 banner or store header adaptations after the master exists

Большинство cover systems fail, когда invent square concept и then force it into a book ratio, или invent cinematic wide и later crop faces off for streaming. Build the commerce crop first. Common print and ratio families such as tall portrait and square formats are well documented in poster and print ratio references (poster size chart; print aspect ratios).

Step 2: genre brief, not pretty scene prompt

Cover brief must encode genre promise:

• literary fiction: restrained palette, solitary motif, painterly grain
• thriller: hard contrast, practical light, clean silhouette
• romance: warm key, intimate scale, soft texture
• sci-fi or fantasy: world scale, symbolic object, atmospheric depth
• indie album: tactile material, one dominant mood, often retro or filmic treatment
• electronic single: graphic geometry or night light with brandable mass

Literary fiction book cover: lone figure on a wind-scoured coastline at dusk, cold teal and amber palette, painterly cinematic light, fine grain, title mass upper third, 3:4

Vinyl single cover: empty neon radio studio at 3am, retro film grain, warm amber bleed, shallow depth of field, clean center logo mass, photoreal, 1:1

Системы «текст в изображение» всё ещё struggle with composition control and fine structure even as surfaces improve (Zhang et al., arXiv 2025; Croitoru et al., diffusion survey). Covers punish those gaps because shoppers do not read failure as "AI quirks"; they read it as wrong genre or low-quality packaging.

Step 3: composition for type and retail reduction

Composition on a cover is not free art direction. It is packaging.

Useful cover composition prompts:

• subject low or off-center with open sky or wall for stacked title
• large symbolic object with simple silhouette for thumbnail recognition
• tight character crop with calm shoulder/background mass for author-title lockup
• wide world shot only when scale is the genre (epic fantasy, ambient albums)

Type strategy for covers

1. Best default: generate an art plate with reserved title mass; set final title and credits in layout software.
2. Short display titles only: one or two words can sometimes live in-image if huge and sparse.
3. Avoid generating full blurbs, long subtitles, and legal as AI lettering.

Poster anatomy references still apply for hierarchy thinking: dominant motif, intentional empty areas, high contrast (movie poster anatomy overview). Covers compress that system harder because the final read is often smaller.

Step 4: postage-stamp review

Используйте этот метод тестирования before calling a cover finished:

1. View the full plate and confirm genre within two seconds.
2. Shrink to a postage-stamp thumbnail and check silhouette clarity.
3. Place a temporary title block and author or artist name in the reserved mass.
4. Check series neighbors side by side: does this plate belong to the same family?
5. If music, check the square under streaming-like graying and compression.
6. If books, check both 3:4 web thumbnail and taller print mock.

Creative hierarchy research and educational creative systems keep emphasizing immediate recognition over decorative density (Google helpful content fundamentals; YouTube ABCD playbook). Covers are the retail package version of that standard.

Step 5: lock series continuity with references

Sequels, trilogies, EPs, and catalog reissues die when every cover is a new lottery result.

Series protocol:

1. Win cover one.
2. Feed it back as a reference.
3. Change only subject, location color, or emblem.
4. Hold light style, grain, type mass position, and contrast grammar.
5. Compare candidates in a three-up strip before approving cover two.

That is the cover-specific craft. Do not relearn product speed tiers here; use the shared explore-stabilize-finalize map on the product hub when you need cost and fidelity staging.

Cover prompt recipes by genre and format

Literary novel (3:4)

Quiet coastal house at blue hour, single warm window, restrained teal and amber palette, painterly grain, large calm sky for title stack, 3:4

Thriller (3:4)

Empty overpass at night under hard sodium light, wet concrete, solitary figure at distance, high contrast, clean upper mass for bold title, 3:4

Fantasy epic (3:4)

Massive ancient gate under storm light, small traveler at base for scale, indigo and copper palette, atmospheric depth, title-safe upper sky, 3:4

Indie album square (1:1)

Torn Polaroid on a sunlit floor, dust in the beam, warm film grade, tactile paper texture, simple center-mass composition, 1:1

Electronic single (1:1)

Neon geometric corridor at night, one vanishing-point light, glossy floor reflections, limited magenta and cyan palette, logo-safe center band, 1:1

For example, a three-book series can keep the same house-at-dusk grammar and only change the weather color and one emblem, preserving shelf recognition without cloning a single image.

Production checklist before packaging files

• genre is readable in two seconds at thumbnail size
• title mass is free of competing texture
• series neighbors share light quality and structure
• music square still works after typical streaming compression
• book plate survives both tall web crop and print mock
• final typography and barcodes remain layout layers when needed
• commercial rights reviewed for the current plan
• account or rights questions can go through the site contact path

Treat the AI plate as packaging art. Spine, back copy, barcodes, and final branding still belong in production tools.

Common failure modes and fixes

Failure	Cause	Fix
Looks premium large, muddy small	Too much micro-detail	Simplify silhouette and raise contrast
Wrong genre at a glance	Mood adjectives only, no genre cues	Specify genre package language and palette code
Title has no home	Edge-to-edge scene	Reserve upper or lower calm mass intentionally
Series feels unrelated	New full roll each volume	Reference lock the winner and change one variable
Forced into wrong commerce crop	Concept made for another ratio	Restart in the real retail ratio

If the plate feels plastic or over-textured after enlargement, artifact checklists such as the ZSky artifacts guide help diagnose surface issues. Run the photoreal workflow checks when full-size materials still fail before you lock genre packaging. For tool selection between Krea 2 and generic generators, use the comparison guide.

FAQ

What is the best starting crop for a novel cover?

Start with 3:4 or the tall portrait ratio your printer and retailers expect, then adapt for ads. Do not invent a square first.

What is the best starting crop for an album cover?

Start with 1:1. Streaming shelves and playlist modules still center the square. Make banners later from controlled adaptations.

Should the book title be generated in the image?

Only for short display titles. Author names, subtitles, and legal are safer as layout layers over a clean plate.

How do I keep a series consistent?

Reference the approved plate every time. Change subject or color temperature only after light style, grain, and title mass position are locked.

How is this different from poster design?

Posters optimize for wall impact and campaign hierarchy. Covers optimize for genre recognition and thumbnail survival in commerce grids. Use the poster spoke above for event key art.

Bottom line

An AI book and album cover maker is a packaging system, not a random pretty-image tool:

1. choose the commerce crop
2. write a genre brief
3. compose for title mass and silhouette
4. pass the postage-stamp review
5. lock series continuity with references
6. finish final type and production outside the generator
