Meaning

Tracing — an accusation that an artist copied another's work by tracing over it.

トレス (from English 'trace') is a serious accusation in art communities, claiming that an artist traced over another's work or a photograph without permission or credit. トレス検証 (tracing verification) posts — where someone overlays two images to show they match — regularly cause controversies on social media. The term is distinct from 模写 (copying by looking) and 参考 (reference), which are considered acceptable practices.

Examples

1. トレス疑惑で絵師が炎上してる。 An artist is getting canceled over tracing allegations.
2. トレスと模写の違いわかってない人多いよね。 So many people don't understand the difference between tracing and freehand copying.
3. トレス検証動画がバズってたけど見た？ Did you see that tracing verification video that went viral?
