Previous article talked about the impact of sublimation ink on the sublimation transfer quality, in fact, there are other factors.
The first is the temperature and time, dye sublimation transfer process requires temperature control in the range of 180 ~ 230 ℃, the transfer time is about 10-30s, but also pay attention to a reasonable allocation of temperature and time.
Then the pressure, the pressure is also one of the important parameters of sublimation transfer process, taking an example of the fabric sublimation transfer printing,If the pressure is small, a large gap between the fabric and transfer paper, yarns rounded, result in pattern blur, visual effect worse; if the pressure is too large, it occurs the morphological changes easily, resulting in feel hard.It is critical for the printed pattern to control pressure.
In addition to the ink, temperature, time and pressure, in the actual production of the production process, there are some considerations. For example, the transfer paper selection,what is more,to ensure the hot surface, the transfer sheet and the substrate surface are connected closely,otherwise it may appear blurred transfer graphic.
