Q1: Can flexo printing achieve the same quality as gravure?

With advancements in CI flexo presses, high-definition plates, and EB (Electron Beam) curing inks, the quality gap has narrowed significantly. For many applications, the difference is negligible to the average consumer. However, gravure still holds a technical edge in ultra-fine detail and color density.

 

Q2: Is PETG film difficult to print on?

PETG is an excellent substrate for both printing processes. Its dimensional stability and surface treatment ensure good ink adhesion and registration. The key is working with a converter experienced in handling and printing shrink films.

 

Q3: Which method is more sustainable?

Flexo printing has a strong advantage here due to the widespread adoption of water-based inks and UV/EB curing systems, which have a lower environmental impact than the traditional solvent-based inks often used in gravure. However, the gravure industry is also advancing in aqueous gravure solutions.

 

Q4: Can I use digital printing for PETG shrink film?

Yes, digital printing** is emerging as a fantastic solution for ultra-short runs, prototyping, and hyper-personalized packaging. It offers no plate costs and incredible design flexibility but is not yet cost-competitive with flexo or gravure for medium to large volumes.
