What happened

Japan’s biggest snack maker has been forced to use black-and-white packaging for some flagship products because of ink ingredient shortages caused by the strait of Hormuz blockade.

Why it matters

Calbee, whose potato chip brands in particular are known for brightly coloured bag designs, said 14 of its products would switch to monochrome branding by the end of May.

Common ground

The move to black and white was forced on Calbee by disrupted supplies of naptha, an ink ingredient derived from petroleum.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
