With dimensions of 500mm x 650mm, the Raisin format has a surface area of 325,000 sq mm or 0.325 sq meters. As the name implies, early Raisin sheets were distinguished by watermarked images of bunches of grapes, denoting the format's use for wine labels, vineyard maps, agricultural records and French rural industry. Although standard ISO sizes now predominate across printing and stationery, Raisin enjoys artistic niche specialty today - particularly for culinary plans, menus, food packaging, recipes and cook books wanting an artisanal style. Its mid-scale dimensions still suit a spectrum of uses from personalized projects to professional documents. So despite its production decline, Raisin sheets are still valued by chefs, bakers, artists, and hospitality/events managers seeking to infuse a touch of farmhouse aesthetic. The engraved grapes recall pastoral days when French fare was local and seasonal offerings were handwritten daily on chalkboards. So the Raisin watermark lives on via devoted locavores and artisans upholding food craft traditions with paper and pen.
