Product Description

The 4.7mm Digital/Analog Flexographic Photopolymer Printing Plate is designed specifically for corrugated board printing, where thick plates are required to maintain consistent ink transfer across uneven board surfaces. At 4.7mm thickness with a Shore A hardness of 36–38, this plate delivers the perfect balance of flexibility and durability for demanding corrugated print runs.

This plate supports both digital (CTP) and conventional analog workflows, giving you the flexibility to choose your preferred plate-making process. The digital workflow eliminates film costs and reduces make-ready time, while the analog workflow provides a cost-effective option for simpler jobs. Compatible with Bowin flexo plate making machines, the plate processes smoothly through back exposure, main exposure, rinsing, drying, detackifying, and post exposure stages.

With an image reproduction range of 3%–95% and screen ruling up to 85 LPI, it handles both fine highlight dots and solid coverage areas with ease — making it the go-to choice for corrugated printers who need consistent quality across varied job types.

FAQ

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

Digital plates (CTP) are imaged directly by a laser without film, offering faster turnaround and higher precision. Analog plates require a film negative for UV exposure. This 4.7mm plate supports both workflows, so you can choose based on your equipment and job requirements.

Q2: Why use a 4.7mm plate for corrugated board?

Corrugated board surfaces are uneven and require a thicker, softer plate to maintain consistent ink contact. The 4.7mm thickness with Shore A 36–38 hardness provides the necessary cushioning and conformability for solid coverage and clean impressions on rough substrates.

Q3: Can I use oil-based ink with this plate?

No. This plate is compatible with water-based and alcohol-based inks only. Oil-based ink, hydrocarbon solvents, and ink containing more than 25% ethyl acetate will cause plate swelling and permanent damage.

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

You need a flexo plate making machine that can handle 4.7mm thickness plates. Bowin offers a complete range of solvent-based plate making machines from BW-400 to BW-2100, covering all standard plate sizes.

Q5: What is the lead time for this plate?

Standard sizes are typically shipped within 7–15 days after order confirmation. Custom sizes may require additional time. Contact us for exact delivery estimates based on your order quantity.

Q6: Do you offer samples for testing?

Yes! We provide sample plates for qualified buyers to test in your production environment. Reach out via WhatsApp or our contact form to request a sample.
