1.In the color comparison,the product with the same texture and the same position is not selected according to the same transfer conditions,transfer on the same base color substrate,and the color comparison conditions under the same light source.
Or the transfer substrate has chromatic aberration.The performance of the sublimation device is unstable.
2.When the heat press machine is processed,the temperature and time of the transfer are not well controlled.Usually,when the transfer temperature is between 120 degree and 220 degree ,the transfer temperature and time are inversely proportional to the color depth of the transferred texture. otherwise,when the transfer temperature is lower than degree ,the transfer cannot be performed,when the transfer temperature is higher than degree ,the color of the texture that has been transferred to the substrate gradually becomes lighter over time.After heat transfer,the product shows spots or fog-like blocks.The surface of the transferred substrate originally has spots or fog-like blocks.The surface of the substrate to be transferred is not resistant to high temperature,and there is a phenomenon of sticky paper or mucous film.
