Cartel de invitación a feria con render 3D de stand

【Editable info】 Brand name: 【brand name】 English name: 【English name】 Industry: 【fragrance / skincare / medical aesthetics / tea & drinks / pets / home & living / packaging / AI tech】 Exhibition name: 【exhibition name】 Booth number: 【booth number】 Date: 【date】 Location: 【venue】 Invitation line: 【short invitation line】 Closing copy: 【short brand-style line】 Primary color: 【primary color】 Secondary color: 【secondary color】 Accent color: 【accent color】 Generate a vertical 9:16 high-end brand trade-show invitation poster, themed around 【brand name】 attending 【exhibition name】. Image type: premium brand trade-show invitation × 3D booth key-visual poster. Overall it should look like a premium brand's exhibition key visual, not an ordinary leasing/recruitment poster, nor a cheap trade-show flyer. Overall style: High-end, grand, clean, restrained, with brand character, ample whitespace, clear information, unified visuals. The image should carry the ceremony of a formal invitation and the commercial polish of a brand spatial proposal. Layout structure: Top: brand logo / brand name / English name, simple and refined; Upper-middle: the large title “INVITATION / 邀请函”, paired with the exhibition name, year, and a short invitation line; Lower-middle: a complete 3D brand booth render as the core key visual of the image; Bottom: keep only the booth number, date, location, and one brand-style closing line. No QR code, no stacked contact details, not too much fine print. 3D booth design: The booth uses a real, buildable professional exhibition-space design, in a 45-degree 3D perspective, with complete structure, harmonious proportions, and clear spatial layering. The booth includes a brand gateway/fascia, glowing LED strips, a reception desk, a product display wall, display cabinets, a hero-product installation, a poster lightbox, a meeting/negotiation area, and accent greenery or refined, industry-related decor. The booth fascia clearly displays 【brand name】 and 【booth number】. The booth design should look like a real brand exhibition render: clean, refined, professional, with premium commercial render quality. Color system: With 【primary color】 at the core, combined with 【secondary color】 and a touch of 【accent color】. The brand primary color should run through the title, info labels, booth fascia, product packaging, LED strips, and spatial details. The overall palette should be low-saturation, unified, and easy on the eyes—not flashy, no promotional feel. Background design: The background keeps large areas of whitespace; you may use soft gradients, subtle paper texture, an airy haze, abstract brand curves, and faint industry-atmosphere elements. The background must not overpower the subject, must not be cluttered, and must not look like an event flyer. Font and typesetting: Clear typographic hierarchy, a grand title, a prominent booth number, simple and readable date and location. Chinese fonts may lean toward a modern serif (Song), a refined sans (Hei), or a brand-feel typeface; English may use an elegant serif or modern sans-serif. The overall typesetting should have breathing room, a sense of order, and premium invitation quality. Lighting and materials: The booth uses soft, bright spatial lighting, realistic materials including acrylic, metal, glass, lacquer, wood veneer, matte surfaces, and the glow of LED strips. The floor may have slight reflection; overall it should be translucent, refined, modern, with real commercial render quality. Quality requirements: High-definition, refined, professional, realistic, high brand integrity, reasonable spatial structure, clear product display, and well-defined information hierarchy; suitable for trade-show participation teasers, exhibition invitations, and social-media posting. Avoid: No QR code, no cheap recruitment style, no promotional-poster feel, not too much fine print, no cluttered background, no deformed booth, no perspective errors, no garbled text, no low resolution, no information overload.
