Create a finished, screenprint-ready T-shirt graphic in a 3:4 portrait format. Show the print artwork only, not a shirt mockup. Use a compact centered emblem with a crisp outer silhouette and black negative space around the saturated printed field. Set the exact text “Definitely not drugs” as the dominant centered two-line headline: “Definitely not” above “drugs”, with the lower line larger; render no other words, letters, numbers, or logos. Build the headline from chunky, rounded poster-display letterforms with thick even strokes, generous closed counters, and close but clear spacing. Fill every glyph with tightly nested concentric contour bands that follow each letter’s silhouette, alternating flat hot magenta and acid green, electric orange and cobalt blue, cadmium yellow and violet. Keep the pairs equally bright and equally valued so their edges visibly shimmer and form a fine moiré; the magenta–acid-green boundaries are the strongest pulsing detail. Preserve clear letter shapes and readable counters. Behind and around the lettering, fill the print area with a kaleidoscopic burst of concentric rainbow waves and op-art spirals radiating to the graphic’s edges. Add a single bold flower-power daisy interwoven with a curling ribbon-like wave beneath the headline, a clear visual emblem for groove and flow; keep it secondary to the words. Use flat, hard-edged, cleanly registered screenprint inks, maximum-saturation complementary colors, and even high-key illumination with no directional shadows. Keep the surrounding black as unprinted shirt ground. Make the composition symmetrical and tightly organized for a wearable chest print. No gradients, muddy colors, photographic elements, distressed texture, extra copy, or 3D lettering.
