GPT Image 2 Pen Poster Prompt: Ink Fold Path

Create a 4:5 vertical premium fountain pen promotional poster, with the core composition being "Ink Fold Path." A dark ink-green metallic fountain pen is placed diagonally from the top right to the bottom left of the frame, with the cap open and parallel in the top right corner, and the gold nib positioned in the center. Below the pen is a continuous sheet of warm white cotton paper, entering from the top left and undergoing three wide folds to form a high-to-low Z-shaped paper path, with realistic fold thickness, fibers, and soft shadows.

A deep blue-black ink flow starts from the nib and moves strictly along the center of the paper path. The ink begins as a thin line in the first segment, spreads into broad strokes in the second fold, splits into several parallel dry brush marks in the third fold, and finally converges into the clear word "TRACE" in the bottom left. The text must be formed naturally by the same ink flow, without adding computer fonts. The ink accumulates realistically and slightly penetrates at the creases but does not flow off the paper.

Only three tiny embossed coordinates are added on both sides of the paper path: NIB, FLOW, PAPER; no arrows or explanatory boxes. The background is a matte dark cyan tabletop, with a color palette limited to dark cyan, warm white, blue-black ink, and a touch of gold.

Use close-up still life photography, with soft light from the top right emphasizing the metal body, nib engraving, and paper fibers, while retaining deeper shadows in the bottom left. Full opaque rectangular background covering the canvas, no transparent corners, no Alpha masks, no edge feathering. No hands, no calligraphy scrolls, no ink splatters, no Eastern decorative patterns, no existing brand logos, no watermarks.
