“United Educational Institute UEI”是使用 FontVibe AI 创作的复古文字效果。衬线大写字母凸版压印进米色棉卡纸，墨色略有破损，放在旧印刷机台面上，周围散落金属活字。

Create a production-ready rectangular invoice-pad rubber-stamp design, 3:2 landscape. The only rendered wording is “Paid in Full”. Center it within a double-line rectangular stamp border, with generous inner padding. Build the words as custom fountain-pen display lettering: a large capital P and F, flowing connected lowercase forms, flexible steel-nib contrast with broad pressure-built downstrokes and hairline upstrokes, slight baseline irregularity, small ink pools at terminal swashes; maintain broad open counters and clear reading at small physical stamp size. “Paid” sits on the upper line and “in Full” on the lower line, with “in” compact and nested before the large “Full”; balanced as a single centered mark. Render in faded oxblood-red rubber-stamp ink (#9D302A), imperfectly transferred onto warm ivory invoice paper (#F3E7CE): dry broken edges, tiny uninked pinholes, subtle uneven density, soft feathering into paper fibers. A thin inner border and heavier outer border show matching distressed ink loss, with tiny ornamental divider dots at left and right. Flat front-facing scan, no perspective, no stamp handle, no hands, no props, no shadows, no other text, no logos, no dates, no currency symbols. Preserve clean negative space around the mark and sharp legibility. Create a production-ready rectangular invoice-pad rubber-stamp design, 3:2 landscape.
