SF-DL Digital Flexo Plates

Low Tack, Reduced Detack
SF-DL is the digital sheet photopolymer specifically designed to address all direct print corrugated board requirements, which delivers higher quality print and increased productivity. SF-DL photopolymer resolves the sticky issue of the previous SF-DGT, which leads to less UV-C detac time or even no detac during the plate making process.

Requires minimum impression settings, giving good balance between solids and screens
Advantage

Superior printing quality with sharper images, more open intermediate depths, finer highlight dots and less dot gain, i.e. larger range of tonal values therefore improved contrast and produce flat top dots when adequate process equipment are used

High resilience and good resistance towards mechanical impacts deliver excellent durability

Increased productivity and data transfer without loss of quality due to digital workflow

Excellent ink transfer using water and alcohol-based inks

Cost effective and more environmentally friendly in processing, as no film is required

Less UV-C detac time is needed, or even no detac
