FAQ

Q1: What is the difference between digital and analog flexo plates?

Digital plates (CTP) are imaged directly by laser — no film needed, faster turnaround, higher consistency. Analog plates require a film negative for UV exposure. This 3.94mm plate supports CTP digital workflow for maximum efficiency.

Q2: Why choose 3.94mm thickness for corrugated board printing?

3.94mm is the standard thickness for corrugated post-print and thick board applications. Its deep relief depth (1.8–2.0 mm) prevents ink flooding in fluted areas and provides excellent cushion for uneven substrate surfaces common in corrugated printing.

Q3: Can I use UV ink with this plate?

No. This 3.94mm plate is compatible with water-based and alcohol-based inks only. UV ink, oil-based ink, and solvents containing >25% ethyl acetate are not compatible and may cause plate swelling or permanent damage.

Q4: What equipment do I need to process this plate?

You need a solvent-based flexo plate processor compatible with 3.94mm thickness. Bowin supplies a full range of plate-making machines — from the compact BW-400 to the industrial BW-2100. View our plate-making machines →

Q5: Are free samples available?

Yes! Free samples are available for qualified buyers to test on their own presses before placing a production order. This ensures the plate performs optimally with your substrate, ink system, and press configuration.

Q6: What is the lead time for this plate?

Standard sizes typically ship within 7–15 days after order confirmation. Custom sizes or large-volume orders may require additional time. Contact us for a precise delivery schedule.
