PDF Studio Editor：編集・スキャン・電子署名

Why this icon holds up

On 2026-08-11 the vault captured the PDF Studio Editor：編集・スキャン・電子署名 icon (Business, US): 蓝色背景，中间是一个红色的信封，信封里露出一张带有灰色横线的白色文档，文档上放着一支黑色的铅笔，信封上写着白色的PDF字样。

No earlier vault capture exists yet, so this dated page is the baseline for future diffs.

Small-size readability

• Contrast: gray mark on blue fill — check both dim OLED and bright LCD.
• Silhouette budget: envelope, document, pencil should remain readable after the store’s rounded-square crop.
• Lettering “PDF” must survive home-screen size; thin strokes usually fail first.
• illustration detail collapses quickly below ~60px — verify the 60px mental model before trusting the master.
• Internal usability score for this capture: 0.6/100 (heuristic, not a store ranking).

These checks are practical references for designers reviewing PDF Studio Editor：編集・スキャン・電子署名, not authoritative store scores.

Transferable design moves

• Keep envelope as the primary silhouette before adding secondary ornaments.
• Concentrate the loudest chroma on the identifying shape (gray), not the whole blue field.
• This capture’s illustration vocabulary transfers best when the same restraint is applied at export size.
