Flexo CTP Machine (Digital Flexo Imager)
Last updated: October 2026
Quick answer: A flexo CTP machine (digital flexo imager) images LAMS flexo plates with a laser — no film, finer highlight dots and in-house plate making on your own schedule. CTPPress supplies flexo imagers with our partner factories and manufactures the digital flexo plates that run on them, so you can source the imager and the plates from one supplier.
Key takeaways
- A flexo CTP machine replaces film: the laser ablates the black LAMS mask, then normal UV exposure and washout finish the plate.
- Compact imagers put digital flexo within reach of mid-size label shops — the decision turns on plate volume and turnaround, not plant size.
- Imagers are supplied with our partner factories; the digital flexo plates are made in our own plant.
- Format, resolution, drum and RIP are confirmed in the quotation for your gauges and line count.
“Outsourcing digital flexo plates is slow” is the complaint we hear most from label and film converters. Every job waits for a trade shop, every correction costs another day, and urgent reprints sit in a courier queue. What buyers want is in-house LAMS imaging on their own schedule. The usual objection is that flexo imagers are huge investments — which is why the configuration has to fit your real plate volume.
What is a flexo CTP machine?
A flexo CTP machine — also called a digital flexo imager or flexo platesetter — writes the image onto a LAMS (laser ablation mask) plate. The laser removes the black mask where the plate should print; the plate then goes through a standard UV back and main exposure, washout, drying and post-exposure. Film, film storage and the registration drift that comes with film all disappear from the label and flexible-packaging workflow.
Laser imaging of flexo plates
Imaging quality is set by the number of laser channels, spot size and drum stability: more channels mean faster imaging at a given resolution, and a stable spot gives cleaner highlight dots. Compact machines image label-format plates, while larger formats serve flexible packaging and corrugated prepress. Throughput should be quoted honestly in m² per hour at a stated resolution, not as a bare plates-per-hour number.
| Decision point | What to check | Why it matters |
|---|---|---|
| Plate format | Largest plate you mount on press | Sets drum size and machine class |
| Resolution | Line count and finest highlight you print | Drives laser spec and imaging speed |
| Plate gauges | Thin label gauges vs thicker packaging gauges | Drum clamping and focus range |
| Monthly plate area | m² per month, peak and average | Decides compact vs high-throughput configuration |
| Washout | Solvent, water-wash or thermal processing | Your existing line usually stays |
Matching imager to plate
The imager must match the plate: a laser source suited to standard LAMS plates, the right drum for your gauges, and RIP screening that suits your line count. Buyers sometimes assume flexo CTP is only for big converters — compact imagers have put LAMS imaging within reach of mid-size label shops, and the economics usually turn on plate volume and turnaround rather than plant size. Because we manufacture digital flexo plates, imaging and exposure settings for our plates can be checked on request when you commission the line.

FAQ
Which plates run on your imagers?
Standard LAMS digital flexo plates, including our digital flexo grades. Gauge compatibility is confirmed for your configuration.
Do I need a new washout line?
Usually not — existing solvent, water-wash or thermal processors finish LAMS plates as usual.
Is a flexo CTP machine worth it for a mid-size label shop?
It depends on plate volume and how much outsourcing delays cost you. Send your monthly plate area and we will size a compact configuration rather than an oversized one.
Disclaimer: formats, resolutions and speeds are typical reference values only and not a guarantee; final configuration is subject to the quotation. Imagers are supplied with our partner factories.
