Why sublimation paper get curl ? How we solve the curling problem ?

First of all , you should know why sublimation paper get curl ? 
Sublimation paper is a coated paper, made up with two important parts : The base paper, and the sublimation coating. Both the two parts 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 moisture of the coating evaporate inconsistently, the paper curls.  The process of the moisture evaporation, we call it “scalability”. 


How to solve the curling problem ? 
1.We use high quality sublimation base paper. Our premium sublimation paper adopts the premium sublimation base paper ( not offset paper). This type of base paper is made up of nature wood pulp (softwood and hardwood), the fiber is longer , and the flexibility of the fiber is better than the offset paper. So the performance and the scalability is better. A better performance and scalability helps to reduce potential to curl. 


2.The anti-curl coating. The base paper has two side : Felt side and wire side. The smoother surface of the base paper is often the felt side. The wire side of the base paper is often considered to be rougher. Typically, sublimation transfer paper is only printed on one side. Accordingly, the sublimation transfer paper only needs to have the sublimable ink receptive coating on the side that receives and holds the sublimable ink. So the smoother felt side will be coated with sublimation coating. The wire side can be left uncoated or can have a coating thereon. 
   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.

How to Avoid Blotchy Results Occurred in Sublimation Process

B lotches and spots in your transfers can happen   at any time  and anywhere . T his is a problem generally caused by excess moisture in the environment or on the substrat e. Left : Perfect transfer result.  Right : Blotches and spots in a poor paper Common   sublimation materials like polyester fabric, hardboard, plastic and even metal materials like aluminum and stainless steel can  be sublimated, and w hat happens when there is moisture on a substrate? When water is heated ,  it turns into steam vapor which starts to escape upward , however, since dye-sublimation ink also turns into a gas, the steam vapor from the areas that have even the smallest amounts of moisture clash with the sublimation gas which will  prevent a full and consistent transfer . So how to resolve this blotchy results ? The quick solution is to pre-press substrates immediately before applying & heat pressing the sublimation transfer. Pre-pressing is done by...

How to print shirts with a sublimation printer and sublimation paper

The sublimation is a fantastic technique customization that allows you to create personalized gifts with maximum image quality a fantastic finish and all with a minimum investment . With a team of A4 sublimation you can create a wide range of customized products for your business, as we present in one of our previous posts . Clearly you can stamp your shirts sublimation printer but have to be of polyester and white or light colored .  Sublimation takes place in two steps : First you have to print your design on   sublimation paper  using your sublimation printer equipped with dye sublimation ink  secondly you have to apply heat and pressure with a heat press machine to transfer the design from paper to sublimable shirt or object. It is in this second step wherein sublimation, that is the chemical process in which heat and pressure deposited on the printed paper, inks become gas and actually takes place penetrate the polyester fiber . The...

Stains and spots on Sublimation: Why the spots occur and how to solve

图片
Almost daily we receive queries such as: "In my sublimations white dots appear," "When sublimate colored spots appear", "Why leave when sublimate colored dots?". It is a fairly common problem in this post will look at the possible causes and how we can implement a solution. Cup with colored dots on Sublimation Use quality materials It is the basis for a good result, so you must ensure that all materials guarantee professional results. 1. Sublimation inks : Use quality inks to achieve rich, vivid colors, sharp contours and durability in your prints. 2. Sublimation Paper : Paper is a very important time to ensure that the ink transfer element is performed correctly. If you use a low quality paper chances are your design run out of ink in some areas and causing white spots appear brighter areas. 3.Customizable: It is essential that the rigid blank product you go to sublimate have an polyester coating quality as our new cup Infinity...
