There are always 2 common heat press machine in sublimation printing, one is flat heat press machine, and another is roller heat press machine. For different heat press machine, we should be careful for different things.Today, we will discuss the points for attention with roller heat press machine
1. First, adjust the transfer speed and drum temperature to an appropriate level. And start you transfer printing tasks after the temperature is stable.
2. Adjust the pressure between the blanket and drum, make sure the pressure is suitable for the paper with different weight.
3. Make sure the heat press surface, transfer paper and surface of substrate must be close, can not have gaps, otherwise it will make the transferred graphics blur.
4. Make a test before mass production to make sure whether the speed and temperature are suitable.
5. Try to clean the things immovably attached to the transfer paper and the textile, or it will influence the image’s quality after transfer printing.
6. The sublimation paper should keep dry all the time. Too much moisture will affect the paper’s quality, and it will cause many problems in sublimation printing such as the direct of the image is sideling.
7. Cut the front part of the paper and fabric into inverted v-shape, and put the middle part into the heat press machine first. It can help the whole breadth enter the roll sublimation machine at the same time steadily.
8. The sublimation paper and textile should be separated quickly when transfer printing. If not, it will be easy to cause ghosting.
Finally, please pay attention to the security. Don’t touch the heat drum when printing, because the temperature is very high, and you will get heart if you don’t pay attention to it.
