There are many factors that affect the quality of the roll cloth transfer process. And it is necessary to master the skills.Today,we are sharing you with several skills to ensure the quality of the roll transfer printing.
1.The transfer speed and the hot roller temperature should be adjusted properly. The temperature must wait for the temperature to fluctuate up and down three times after reaching the set temperature. And performe the transfer operation after the temperature is stable.
2.Depending on the weight or stiffness of the paper, fine tune the pressure between the felt and the hot roll.
3.To maintain the same degree of tension between the transfer paper and the fabric, stabilize the proper tension.
4.Before transfer printing, make a transfer sample to determine if the temperature and speed of the affected color are appropriate.
5.Before the transfer, we need to blow and defragment the printed surface of the transfer paper and the fabric to remove paper dust, cilia and other attachments.So as to avoid the print defects caused by the inclusion of these debris in the transfer paper and the fabric.
6.To ensure that the transfer paper is dry, the transfer paper with a large amount of moisture will generate a large amount of water vapor during the heat sublimation process. That will cause the transfer paper to soften and lose its stiffness, causing problems such as oblique walking and water ripple.
7.When transferring, you can cut the front of the paper and fabric into inverted V-shape to let the middle advanced. Or you can use the cardboard leading end larger than the width of the transfer paper. So that the entire surface can be smoothly and smoothly fed into the transfer machine. Avoid crushing and pulling leads to wrinkles on transfer.
8.During the transfer process, we should fast separate the paper. That will prevent the paper cloth from coming into contact with it to cause secondary sublimation transfer and ghosting.
9.Pay attention to the safety of the operation during the transfer process. Don’t be close to approach the hot roller and to avoid high temperature burns.
We believe that if you get the skills above,the quality of the roll transfer printing will be guaranteed.
