•More and more enterprises are using eco-friendly materials (e.g., recycled paper, vegetable-based ink) for printed materials. For example, FMCG brands have switched to "degradable pulp boxes" for product packaging, using "soy ink" for printing. This not only reduces environmental pollution but also gains consumer favor through "eco-labels" on packaging. Data shows that brands adopting green printing see a 28% increase in consumer favorability.

•"Recyclable printed materials" are also emerging—e.g., enterprises customize "reusable paper notebooks" with erasable QR codes on the inner pages. Users can scan the QR codes multiple times to obtain the latest information, reducing paper waste while extending the service life of printed materials.

•Smart label printing: Enterprises print "NFC smart labels" on product packaging; users can touch the labels with their phones to obtain product traceability information and usage tutorials, and even jump directly to brand communities—enabling "one product, one code" precision operation.

•Photosensitive color-changing printing: Brands use "photosensitive ink" in brochures; when users expose the brochures to sunlight, the ink reveals hidden patterns or text (e.g., discount codes, new product previews), enhancing user engagement through "fun interaction."

•Temperature-sensitive printing: Catering brands use "temperature-sensitive ink" on menus; when dishes are served, the introduction text of the corresponding dishes on the menu changes color, reminding users to "eat while hot." This not only improves the dining experience but also strengthens brand memory.
