[Purpose]
Korean calligraphy and brush-lettering class poster, A4 vertical editorial flyer for studio promotion.
Designed for workshop signup, with a tactile print-poster composition that emphasizes brush, ink, hanji paper, class details, and handmade lettering atmosphere.

[Composition]
- Overall layout: A4 portrait poster with a top studio logo zone, a bold headline band beneath it, a central hero image area occupying about 42% of the frame, and a detailed class-information block at the bottom.
- Subject placement: {hero 이미지} sits as the main visual anchor in the center-mid area, surrounded by natural studio-context details such as ink stone, brush rest, stacked hanji sheets, drying brush strokes, and small paper labels that support the workshop theme.
- Background treatment: matte hanji-paper texture in warm beige, with visible fiber grain, slight deckled edges, faint ink smudges, and subtle pressure marks from real printed paper.
- Spacing and framing: left-aligned text hierarchy with editorial rules, brushed dividers, tiny registration marks, and a practical poster rhythm readable from a distance.
- Poster enrichment: include event details, date/time/venue, ticket or signup information, sponsor/cooperation area, a small QR-style signup box, a red accent tag, and decorative ink-wash graphic elements that feel hand-printed rather than digital.
- Use {공방·로고}, {헤드라인}, {수업 종류}, {일정·가격}, {hero 이미지}, {컬러 팔레트}, {비율} placeholders exactly where the customizable content belongs.

[3. CORE STRUCTURE]
- Top band: place {공방·로고} near the upper center as a studio mark, styled like a refined workshop masthead. Add tiny editorial metadata nearby: "VOL.03 WORKSHOP POSTER" and "봄학기 수강생 모집" in small, crisp type.
- Headline band: set {헤드라인} directly below the logo area, larger and more dramatic, with the feeling of brushed ink on paper and a strong vertical presence. Include the short supporting line "먹 향이 남는 저녁 클래스" beneath the headline.
- Hero area: show {hero 이미지} in the center as a close-up editorial composition of brush, ink, paper, or handwritten stroke detail; keep it crisp, tactile, and naturally imperfect. Add visible ink pooling, feathered stroke edges, a small ceramic ink dish, brush fibers, paper fibers, and a few handwritten practice sheets partially overlapping.
- Course information block: place {수업 종류} as a compact multi-line list, clearly separated with line breaks, dot separators, or thin charcoal rules. Add a small red label reading "초보 환영" and a stamp-like decorative accent reading "모집중".
- Schedule and pricing block: position {일정·가격} near the lower third in a smaller but still prominent type size, using structured lines for weekly schedule, price, trial class, materials included, ticket/signup status, and reservation note.
- Event detail row: include "2026.05.18 개강", "매주 화·목 저녁 7:30", "장소: 서촌 작업실 2층", and "정원 8명" as practical poster information.
- Signup/footer area: add "예약 문의 010-1234-5678", "@ink_studio", "신청 QR", "재료비 포함", "현장 결제 가능", and "EARLY BIRD -10%" in small supporting text, plus a sponsor/cooperation line "협력: 한지상점 고운결".
- Footer balance: use the lower margin for a realistic printed flyer finish with small contact text, a QR-style square, light ink flecks, and fine paper texture.

[4. STYLE RULES]
- Typography: combine a bold Korean serif style similar to Noto Serif KR or Nanum Myeongjo for the headline, with a clean sans-serif such as Pretendard for supporting details; headline weight heavy, body weight regular to medium, sizes clearly separated by hierarchy.
- Color palette: use {컬러 팔레트} with hanji beige, sumi black, seal red, and charcoal; keep the red as a controlled accent for labels, small stamp marks, and signup emphasis.
- Graphic system: use thin editorial rules, hand-brushed divider strokes, small vertical labels, understated registration marks, and a QR-style signup block to make the poster feel like a real workshop flyer.
- Border/shadow: allow a subtle printed-paper edge, faint ink-wash corner texture, and a soft shadow under the hero detail, about 3px y-offset, 10px blur, 12% opacity, to preserve a tactile printed-poster feel.

[5. VISUAL STYLE]
- Camera / lens: editorial still-life captured with a Canon EOS R5, 50mm lens at f/4, or an 85mm lens at f/2.8 for a tighter close-up of brush and ink texture.
- Lighting: soft diffused window light from upper-left at roughly 45°, with a gentle fill on the right side; preserve paper grain, ink edges, brush hairs, and ceramic ink-dish texture without harsh specular highlights.
- Color grade: warm cream and paper beige base, deep charcoal blacks, muted vermilion red accent, and slightly desaturated tones for a calm print-editorial finish.
- Material realism: show absorbent hanji fibers, uneven ink density, tiny brush bristle marks, slight paper curling, and authentic offset-print softness in small text areas.

[6. MOOD]
Premium Korean arts workshop editorial — feels like a refined gallery class poster combined with a warm neighborhood studio signup flyer, tactile, crafted, calm, and inviting.

[7. CRITICAL]
- Korean text accuracy: "붓끝에서 피어나는 시간.", "한글 캘리", "한자 서예", "영문 캘리", "손글씨 다이어리", "디지털 캘리(아이패드)", "주 1회 2시간", "4주 16만원", "1회 체험 4만원", "도구 포함"
- Additional poster text accuracy: "봄학기 수강생 모집", "먹 향이 남는 저녁 클래스", "2026.05.18 개강", "매주 화·목 저녁 7:30", "장소: 서촌 작업실 2층", "정원 8명", "예약 문의 010-1234-5678", "@ink_studio", "신청 QR", "재료비 포함", "현장 결제 가능", "초보 환영", "모집중", "협력: 한지상점 고운결", "VOL.03 WORKSHOP POSTER", "EARLY BIRD -10%"
- The composition must remain A4 vertical with a clear top-to-bottom hierarchy: logo, headline, hero, course list, schedule/pricing, signup/footer details.
- Keep brush stroke edges, ink texture, paper grain, QR-style box, small contact text, and all Korean characters crisp and correctly formed.
