AI Technical Summary

Technical Problem

DTF thermal transfer sheets typically use PET film as a substrate which is discarded after transfer printing, and there is a significant loss of printed images due to the image remaining on the substrate when it is peeled off.

Method used

A substrate for DTF thermal transfer sheets comprising a water-dispersible paper layer and a water-soluble resin layer, allowing for removal by immersion in water while maintaining image transferability.

Benefits of technology

The substrate enables easy removal after transfer printing and ensures excellent image transferability without deformation or ink penetration, improving the efficiency of the DTF printing process.
