Book Cover Launch Checklist for Indie Authors

Open Midjourney and craft five prompts that combine your genre keywords with visual adjectives (e.g., "dark gothic thriller, moody lighting, crimson accents"). Generate 4‑5 images per prompt, then export the best results. Import the images into Coolors (https://coolors.co) to extract a 5‑color palette, ensuring contrast ratios above 4.5:1 for readability. Save the moodboard in a shared Google Drive folder, and annotate each image with notes on dominant motifs, color temperature, and composition trends that align with top‑selling Amazon covers.

Search your primary keyword on Amazon KDP and filter by "Top 10 Best Sellers". Screenshot each cover and paste into an Excel audit sheet. Score each on a 0‑10 rubric: genre relevance, title legibility at 1,600 × 2,560 px thumbnail, font hierarchy, and color harmony. Weight readability 30 % and genre fit 40 %. Total the scores; any cover under 65 warrants redesign. Record the bestseller rank and price to correlate visual strength with sales performance, providing a data‑backed baseline for your own design.

Create a one‑page persona in Notion or Google Docs. Fill sections: demographics (age 25‑45, gender split), reading habits (average 30 min per session, prefers Kindle), price sensitivity (willing to pay $4.99–$6.99), visual preferences (dark palettes, minimalist typography). Add a "Visual Triggers" bullet list derived from your moodboard. Validate the canvas by posting a short poll on your author newsletter and adjusting based on responses. This persona guides every design decision, ensuring the cover resonates with the exact audience you aim to convert.

Log into DesignLumo (https://www.designlumo.com) and input a precise prompt: "Create a 6 × 9 in fantasy novel cover, dark blue background, gold serif title, glowing rune symbols, and a central silhouette of a dragon." The AI returns a fully layered PSD in under 30 seconds. Open the file in Photoshop, replace placeholder text with your title using the suggested font, adjust colors via the Brand Kit, and export. This replaces a $100‑$250 designer fee, cutting production cost by 90 % while delivering print‑ready layers.

Upload the Lumo PSD into Canva Pro (https://www.canva.com). Use Canva's font library to test three serif options for the title, ensuring the text remains legible at 150 px width. Apply the WebAIM Contrast Checker (https://webaim.org/resources/contrastchecker/) to confirm a minimum 4.5:1 ratio against the background. Enable "Text Spacing" to adjust tracking by +0.05 em for readability. Save each variation as a PNG, then compare side‑by‑side in a Google Slides deck to select the highest‑impact typography.

Open Adobe Express (https://www.adobe.com/express) and select "Custom Shape". Draw a vector rune or emblem that matches your genre, using the Pen tool with a 300 dpi canvas. Export the illustration as an SVG (<2 MB) and import it into your DesignLumo file, replacing the placeholder graphic. Verify that the SVG scales without pixelation by zooming to 200 % in Photoshop. This adds a unique visual hook that differentiates your cover from generic stock assets, boosting perceived value.

In DesignLumo, use the "Export" panel to generate four assets: PDF (CMYK, 300 dpi, 6 × 9 in) for print‑on‑demand, JPEG (RGB, 2,560 × 1,600 px) for Amazon KDP, PNG with transparent background (2,560 × 1,600 px) for Audible, and a 1,400 × 1,400 px square for Kindle thumbnail. Run each file through Adobe Acrobat's preflight to confirm no embedded fonts are missing. Upload the PDF to KDP, then cross‑check the live preview for spine width using the formula: spine = page count × 0.0025 in. This prevents costly re‑uploads and ensures consistent print quality.

Create two distinct cover variants (e.g., different color schemes). In Amazon Advertising (https://advertising.amazon.com), set up a Sponsored Brands campaign with $5/day budget per variant, targeting the same keyword set for 14 days. Track click‑through rate (CTR) and conversion rate (CR) via Amazon Attribution. Aim for CTR > 0.7 % and ROAS > 2.0. After the test, pause the lower‑performing ad and replace the live KDP cover with the winner. This data‑driven swap can lift monthly sales by 12‑18 %.

In DesignLumo, open the "Brand Kit" module and define primary colors, secondary accents, and two font families (title and body). Save these as global variables. For each book in your series, clone the master cover file, and the variables auto‑populate, ensuring visual consistency. Export a one‑page PDF style guide that lists hex codes, font names, and usage rules. Calculate spine width for each volume using the page‑count formula (spine = pages × 0.0025 in) and adjust the layout accordingly. Consistent branding drives repeat purchases and reinforces author authority.
