SF-LADF Laser Ablation Film

High Contrast Flexo CTP Film
SF-LADF is an eco-friendly product independently developed by Strong, which reduces the plate making process, improves efficiency, and reduces emissions. A protective film covers the surface of the ablated black mask which will be removed before use, and the film is compatible with most CTP devices on the market such as Esko (1064nm infrared laser) and Cron (830nm infrared laser). It has high optical density, good stiffness, and adequate ablation sensitivity, which can replace silver halide film in most of its applications especially for analogue flexographic plate making.

Holds the finest detail without the need to back mask
p-d-3.png
Quick wash out
p-d-4.png
Requires minimum impression settings, giving good balance between solids and screens
Advantage

The thickness of PET can be 7mil(175μm) and 5mil(125μm)

Additional protective film prevents the black film from being scratched before ablation

High contrast, high resolution (1-99%@ 175lpi), and high optical density

Adequate ablation sensitivity, suitable for various types of CTP laser machines on the market

Use in open rooms, and suitable for post printing of corrugated plates and other paper substrates

Technical specifications
Size Specs 0.635×60 Meter/roll; 1.27×30 Meter/roll; can be cut into pieces according to request
Thickness 175μm/125μm
Material PET polyester base
Min Optical Density ≤0.03
Max Optical Density ≥4.0
Laser Ablation Energy 3.2--3.8J/cm²

NOTE
1. The laser ablation energy depends on the types and ages of the machines. Before use, additional tests need to be done to find the 
right ablation energy.
2. After removing the protective film, the film surface needs extra care to prevent scratches. Rubber gloves are suggested to use to 
prevent fingerprints and scratches.
3. The suggested store conditions are placing flat in its original packaging, below 28 ℃temperature, below 70% humidity, and the shelf 
life is 18 months.

*Run-Length varies with its printing conditions and imaging content
