Low-Weight and High-Weight Sublimation Paper,How to Choose?

The sublimation paper including low-weight sublimation paper and high-weight sublimation paper.At present,there are 58g,75g,80g,90g,100g,120g on the market.But do you know how to choose them?Which one is more suitable for your product? 

How to choose the gram weight of sublimation transfer paper?

Low-weight sublimation paper

According to the transfer requirement of the ink

(1).If the textile requires little ink , such as summer clothes , you should choose 58g,80g,90g and 100g dye sublimation paper . As long as you control the humidity in 40%-60% RH, the paper will work very smoothly .
(2). If the textile requires a lot of ink , for example , print a large area of dark color , you’d better choose 120gsm sublimation transfer paper . But currently , if you only have 80g and 100g at hand , please make sure do not let the paper become damp . Then you need control the humidity around 50%RH. With those efforts , you could also use 80g and 100g to print a large area of dark color .

According to the humidity of the working environment

(1). Low humidity . In the humidity under 45%RH , It’s better to choose 75gsm sublimation paper. Because when in a low humidity , the paper will shrink, and the print side is hunch-up. During the printing , the paper absorb ink , the “hunch-up” will be more obviously. 100g and 120g paper are harder than 80g , so the “hunch-up” will damage the print head . 80gsm is more softer , it could relief the “hunch-up” and protect your print-head from damage .
(2) . High humidity . In the humidity above 70% RH . It’s better to choose 120gsm . Because the paper is very easy to become damp in a high humidity , it will become softer and stiffness is weak at the same time . If you use low weight paper, it will be very hard to print smoothly because of the stiffness and hardness go down . At this time , 120gsm is your best choice.

High-weight sublimation paper

If your fabric is elastic, sticky sublimation paper is your best choice. At present, 100gsm sticky paper is the most popular in the market, and it can avoid double printing image on the fabric.

In the case of printing on open substrates, four criteria should be considered for the correct paper choice: Ink load, pattern difficulty, web tension control and printing speed.

Criterion 1 ­ Ink loading

This is the general and dominant rule. The higher the ink loading, the heavier the paper has to be in order to accept the moisture from the ink without any problems. The relationship between ink loading and paper weight results directly from the water absorption by the paper.

Criterion 2 ­ Difficult patterns

Difficult patterns demand heavier paper.
What is a “difficult” pattern in this context? One that has:
(1)an asymmetrical design
(2)blotches or bands with little or no ink alternated with blotches or bands with a high ink loadingRoll-to-roll transfer in a transfer calendar
Difficult patterns pose a challenge for the paper’s dimensional stability because they create big, local differences in the amount of ink that will be absorbed. At the borderline between low and high ink loading, the transfer paper has a tendency to cockle.

Criterion 3 ­ Roll-to-roll or roll-to-sheet

Roll-to-roll operation of the printer allows for a certain amount of tension control. Although the different types and makes of printers vary considerably in this regard, as a general rule roll-to-roll printing results in better process control than roll-to-sheet, in which the paper web is cut off immediately after the printing heads. Additionally, when the printed paper is processed from the roll in a transfer calender, conditions are ideal for the use of a low-weight sublimation transfer paper.

Criterion 4 ­ Printing speed

The higher the printing speed, the lower the paper weight can be. Cockling causes problems mostly when it happens directly beneath the printing heads. The papers for open substrates are designed to slow the water absorption in the paper structure. From this, a higher printing speed takes the cockling away from the danger zone under the printing heads.

So, how to choose sublimation paper depends on your product, the grams are different for different products.
