Several Methods of Temperature Measurement in Thermal Transfer

When the transfer paper is in the dryer, you can measure the temperature at that moment using a temperature bar or a more expensive ring detector. From the use of experience, the temperature-sensitive temperature bar is better and easier to use. The ring detector can measure more accurate values, but it can hinder product entry when it enters the dry crucible. In addition, you can use a non-contact thermometer, but the temperature it reads only shows the dryer temperature at the time, and it does not show how high the temperature rises when the transfer paper passes through the dryer.

In order to measure the output of the radiant dryer, the temperature bar gives an approximate temperature value. The "approximate value" is also sufficient for this type of measurement because there is no way to give an absolutely accurate temperature value.

Of course, the most authoritative test is practice. When you transfer a printed transfer paper image onto a silk fabric, as long as it can perform the transfer task well, it means that it has been fully dried. To further verify whether the drying parameters meet the requirements, it is necessary to perform a rinse test on the transferred silk fabric. If it can be washed, it will further prove the correctness of the drying parameters.
