When dealing with sublimation, some people may have encountered a big and serious problem

- the sublimation paper curls and scratches the printer head. The worst result is that you take

some money from your pocket and change a new printer head. At that time, you will have to find

a way to reduce your cost to remain your profit. Today , we are going to offer you a solution to

help you out of that problem --- curling ! 

First of all, why sublimation paper get curl ? 

Sublimation paper is a coated paper, made up with two important parts : The base paper, and the

sublimation coating, which all have contains moisture. When you put the sublimation paper in a

environment of dry air and high temperature, the moisture will evaporate. At this time, if the moisture

of the base paper and the coating evaporate inconsistently, the paper will curl. The process of the

moisture evaporation, we call it “scalability”.  

Second, what’s the consequence of curling problem ?

As we stated above, When you are printing a heavy ink loading, the paper will scratch and damage

the printer head once the paper curls. 

Third, how to solve the curling problem ? 

1.We adopt high quality sublimation base paper instead of the offset paper. This type of base paper is

made up of nature wood pulp (softwood and hardwood), which fiber is longer, and more flexible than the

offset paper. So the better performance and the scalability can help to reduce the possibility of the curl. 

2.The anti-curl coating. The base paper has two sides, smooth side and rough side.   Typically, sublimation

transfer paper is only printed on one side. Accordingly, the sublimation transfer paper only needs to have

the sublimation ink receptive coating on the side that receives and holds the sublimation ink. So the smooth

side will be coated with sublimation coating and the rough side can be uncoated. 

3.But if the paper is only coated on one side, the structure is not stable and balanced, the paper many have

an increased tendency to curl. So the second method to preventing curling problem, is to coat the wire side

with a functional coating too. The functional coating ,or named as anti-curl coating, could provide the

sublimation transfer paper enhanced stability. 

With above two solutions, we solve the curling problem perfectly. Saving paper cost does not mean saving

the total cost. Always a better quality help you  to improve your productivity and to protect your other equipment,

that’s the real saving !
