How Can We Avoid Humidity Affect Sublimation Printing?

Many things may affect the effect of sublimation process, including substrate and sublimation paper. Let’s talk about the common situation:

1. Color shifting (colors lose accuracy)
2. Image bleeding
3.Uneven transfer of solid filled areas of a design.

sublimation printingThe high humidity will influence the drying speed of sublimation paper in sublimation transfer printing process. It will be very low and the worse situation is caused by paper touching the printing head. Most of customers may have this problem. Therefore, it is very important to control indoor humidity.

I suggest each customer should have a hygrometer to measure temperature and relative humidity (RH).

How can we do to avoid the effect of humidity of sublimation printing? So the followings are important humidity factors you should focus:

1.Avoid the moisture that comes with your clothes.

First you should restore your sublimation paper carefully. They should be placed in a cool & dry place to avoid direct sunlight. When dealing with your clothes, if you suspect there may be moisture in it, you can pre-press the clothes for about five seconds to warm it.

2.Control the indoor humidity

You should control the indoor humidity from 50 to 60%. The 50-60% humidity helps keep paper smooth printing, and also make sublimation paper and sublimation ink dry quick. If the indoor humidity is too high, you can open your air condition to create a dry room of stable humidity and temperature. But it may cost you a lot of budget.

How to Compare the Transfer Rate of Digital Sublimation Paper?

As we all known, the transfer rate of digital sublimation paper decides the sharpness and the color of textile. So we need to choose high transfer rate sublimation paper if we want to get good product. However, do you know how to compare the transfer rate of digital sublimation paper? I hope this article will help you. 🙂

Customers when judging transfer rates of digital sublimation paper can be a “parallel experiment”, the method is to take you need to compare several kinds of inkjet sublimation paper with double-sided tape together side by side, then on the printer to print together lateral 2cm wide strip CMYK color piece, again after 1 hour together on the same fabric, such as thermal sublimation transfer printing at the same time, high concentrations of cloth color or color less high transfer rate remains on sublimation transfer paper.

sublimation transfer paper(1) To select the same type of sublimation heat transfer paper, such as the Sublistar or Feiyue factory: each type high weight sublimation paper – low weight sublimation paper – sticky sublimation paper – industrial heat transfer sublimation paper (jumbo roll, mini jumbo roll, 3.2 meters of the sublimation paper)

(2) Do not only focus on the transfer rate, but also take into account the drying speed and smoothness of printing, without smooth printing, the transfer is meaningless.

sublimation paperOur sublimation transfer paper which transfer on all kinds of polyester textiles materials(soft and hard substrates). Which is superior quality for digital printing for sportswear, blankets, curtains, wider wall covers, tents, banner, flag, skis and snowboards.

To ensure the smoothness of the paper, we coated with three times. Pre-coated before coating the liquid, and also back coating. Paper will never curled when printing.

How Does Sublimation Base Paper Affect the Quality of Transfer Paper?

In the market, there are two different quality sublimation paper: the high quality one and the economic one. One of the reasons that cause the quality difference is the base paper.

sublimation base paper

1. High Quality base paper
This type of base paper is made up with needlebush pulp(softwood) and broadleaf pulp(hardwood), the ratio is 7:3 normally.

The fiber is longer, it means the intension of the paper and the capability of enduring high temperature is better, that will make sure the paper still have best intension in continuous production process under high temperature, that could protect your paper from breaking which will cause badly influence to your production.

Also the tightness is greater, above 0.9g/cm3, the air permeability is smaller. If the thightness is smaller, then the air permeability is greater, that means during the transfer, the sublimation ink will penetrate the base paper and spread to the back side, and influence the transfer result.

2. Economic base paper
This type is made up with various kinds of mixed pulp of waste paper, such as newspaper, packing paper etc from our daily life or industrial waste paper. No matter the intension, the capability of enduring high temperature, the tightness, the air permeablility, it is weaker than the up-grade base paper.

Our company offers the equipment in sublimation printing process, such as sublimation paper, sublimation ink, inkjet printer and some other accessories. If you have any demand, please feel free to contact us.
