AI Technical Summary

Technical Problem

Traditional thermal sublimation transfer paper is inadequate in terms of rapid drying and high ink transfer rate, making it difficult to meet market demands.

Method used

Using nanocellulose-based thermal sublimation transfer paper, an ink barrier layer is laminated on the base paper. The nanocellulose ink flocculant reacts with the pigment particles to prevent pigment penetration and improve ink transfer rate, while accelerating the drying process.

Benefits of technology

It achieves rapid drying and high ink transfer rate, improves print clarity and ink absorption capacity, and provides paper performance with no curling and low shrinkage.
