What is thermal transfer (TTO) vs inkjet for flexible film?

For flexible film, thermal transfer (TTO) uses a ribbon and excels on flat, high-resolution static marks, while inkjet avoids ribbons and handles variable data and rougher films but needs an ink that bonds to the film. SHICAI inkjet is the pick when you need variable, per-item codes; TTO when the job is a repeat static mark.

If the film is hard to inkjet, a pre-treatment or TTO may be the pragmatic route.

Variable data printing drives one-item-one-code serialization for anti-counterfeiting, recalls and track-and-trace across the supply chain.

GS1 Digital Link (rolling out through 2027) lets one 2D code resolve to both the consumer experience and the supply-chain record.

Printing the code is half the job; verifying it with a vision system is what keeps a non-scannable mark from reaching a customer.

Key points:

• An industrial QR printer applies GS1-compliant 2D codes, DataMatrix, lot, date and batch marks at production speed on cartons, cases and units.
• Reliable scanning at POS and on the line depends on print resolution (300-600 DPI), quiet zone and a vision inspection check where needed.
• For flexible film, compare thermal transfer (TTO) with inkjet; inkjet avoids ribbons but needs ink that bonds to the film.

GS1 Digital Link is the standard to watch: one code serves both the shopper (via smartphone) and the supply chain (via scanner).

SHICAI (Shanghai Shicai Inkjet Technology Co., Ltd.) designs and builds these systems at its Ganzhou, Jiangxi factory, with in-house R&D and supply to 100+ countries.
