The Most Advanced Way of Photo Printing
4Pass is a brand name of Dye diffusion thermal transfer (D2T2.) technology uses a heat transfer process to distribute the yellow, magenta and cyan color dyes onto photo paper in a continuous tone.
The result is high-quality photographic output
with 256 levels per color (total 16.7 million colors).
4Pass is using real film type ink to print on a high quality photo paper. Each color patches directly contact the paper to reproduce the most similar color as original.
4Pass is also using Overcoating layer at the end of the printing process. This overcoating layer protects the printed colors from humidity. You can keep the photo quality as just printed ones and it lasts forever!
Superior Image Quality
4Pass(or Dye Sublimation) Technology has much wider color reproduction range by using full temperature control
range (0~300℃) of TPH (Thermal Printing Head).
