095リソグラフ風のイベントポスター

Generate one finished risograph event poster now, as flat portrait artwork, default 3:4. The signature is an INK-PLATE DUET: a single event motif rebuilt from two complementary stencil silhouettes, one in each principal ink. The subject comes from the motif input, not a generic decorative background.

TITLE "【タイトル】"
DATE "【日付】"
STENCIL SUBJECT "【版のモチーフ】"
INKS "【インク】"
PLATE ARRANGEMENT "【版の配置】"

Build the selected plate architecture first:
重ねる: unite both stencils into ONE monumental central emblem. First-ink silhouette and second-ink silhouette interlock and overlap through its middle, creating a visible third mixed-color intersection. Leave the title above this joined emblem and date below. No detached left/right specimens.
開く: pull the two stencils completely apart into LEFT and RIGHT wings with a broad unprinted vertical corridor between them. First ink occupies the left wing; second ink occupies the right. Set the title in horizontal short lines within that central corridor and the date beneath the title in the corridor. The wings never touch each other. Do not retain a central emblem. This is one designed poster, never a comparison sheet or two separate posters.

Draw the supplied subject using chunky cut-stencil contours and coarse ink flecks. For a plant subject, make complementary branching leaf silhouettes, not two copies of a complete potted plant. For paper crafts, use folded and cut paper profiles; for music, use resonant abstract instrument silhouettes. Never print the subject description or arrangement names. Title and date are the ONLY visible text, each once, precisely as entered, in their supplied language. Keep type solid and clear of overprint textures. Empty date removes its entire line without inventing a date. Empty subject takes its cue from the title.

Uncoated warm ivory paper is unprinted substrate. Use the first two supplied spot inks for the two silhouettes; an optional third ink is reserved for the title and date. With two inks, use the darker one for text. Blank inks default to forest green and coral. One supplied ink receives a contrasting second; ignore colors beyond the third. The intersection in joined mode is an overprint mixture, not an extra ink. Papery tooth, dry grain and softly imperfect stencil edges; small registration errors belong only to the artwork, never to letters. No smooth gradients or photographic material. Keep all wording comfortably inside the trim, allow peripheral silhouettes to crop at the edges.

No plate numbers, swatches, arrows, production notes, invented venue, prices, logos, artist references, QR patterns, watermarks or room mockups. Use original fictional event artwork. No reference photograph needed. Return only the finished poster; this is a raster simulation, not a set of press separations.
