「SISE-NEG」は FontVibe AI で作成したカスタムスタイルの文字エフェクトです。

Square poster composition with the exact text "SISE-NEG" centered as one large line, occupying the middle 55% of the frame with generous clear space around every edge. Build a late-1960s concert-poster environment behind it: a deep midnight-indigo paper field with visible uncoated screen-print grain, layered concentric sunburst arcs radiating from behind the word, and broad coral, saffron, and muted turquoise bands that stop well before the text area. Place symmetrical curling botanical silhouettes in the lower corners, printed as flat dark-indigo ink shapes, with small five-petal flowers and rounded leaves. A thin crescent moon sits high above the centered text, while two tiny distant stars remain confined to the upper corners. Use matte ink layers with slight registration offsets only in the background artwork, subtle paper fibers, and soft vignette darkening at the outer border. Keep a clean, uninterrupted central negative-space zone behind the text so each character remains sharply legible. Front-facing flat poster view, crisp high-resolution print detail, balanced radial composition, no additional words, no numbers, no logos, no lettering anywhere else.
