How To Solve The Moisture Problem Of Sublimation Printing Paper?

The introduction of moisture into the sublimation printing process can cause unwanted results. During production with a heat press operating at 400°C /204°C, moisture can flash to steam and literally blow the ink away from its intended target. Some of the problems that are attributed to moisture include color shifting , image bleeding and the uneven transfer of solid-filled areas.

Under normal circumstances, a small amount of moisture can accumulate in the transfer paper and it’s usually absorbed directly into the substrate during pressing. However, hard substrates, like metal and ceramic, are unable to absorb excess moisture. Thus, it’s important that you take steps to minimize the introduction of moisture into the process.

The first step is to protect the paper from moisture absorption. As a preventative measure, store your paper in a dry place. Consider a sealed container such as a re-sealable bag. If you suspect moisture, set the paper on your press for a few seconds. Do not press it; just expose it to the warmth. The heat radiating from the press should help evaporate most of the moisture.

Another trick is to use newsprint or butcher paper instead of a Teflon sheet. The heat transfer paper will help absorb moisture from the transfer sheet during pressing, whereas Teflon will not. Be sure to use a fresh sheet of paper for each pressing cycle.

If you are working with garments or fabric, it’s also possible that the substrate may contain some moisture. Pre-pressing the garment for about 10 seconds should remove the moisture, as well as any wrinkles. To avoid this problem, keep your paper or fabric in a dry place. If you suspect moisture, try these techniques:

1) Place paper on the raised pedestal bottom of the press and let it dry under the heat platen. Don’t close the heat platen!
2) Pre-press fabric for 10 seconds before transferring
3) Use a fresh, non-textured paper towel behind the transfer sheet

Base Paper of Sublimation Printing Paper

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

sublimation printing paper

Now there are two kinds of base papers that used to making dye sublimation paper in the market.

1. High Quality base paper.
dye sublimation paperThis type of base paper is made up of needlebush pulp(softwood) and broadleaf pulp(hardwood), the ratio is 7:3 normally.
The fiber is longer, it means the intention of the sublimation paper and the capability of enduring high temperature is better, that will make sure the paper still has the best intension in continuous production process under high temperature, that could protect your paper from breaking which will cause the bad influence to your production.
Also, the tightness is greater, above 0.9g/cm3, the air permeability is smaller. If the tightness 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 backside, and influence the transfer result of sublimation printing paper.

2. Economic base paper.
dye sublimation paper This type is made up of 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 intention, the capability of enduring high temperature, the tightness, the air permeability, it is weaker than the up-grade base paper.

Anyway, in the sublimation industry, if you are lucky in using the right paper, no problems occur; if you are using the wrong paper, many problems could happen, and the problems will be more and more.

Fei Yue Digital Inc. is based on papermaking and has our own paper making factory. Our sublimation transfer paper has a microporous coating for faster sublimation printing. Any questions, welcome to contact us.

How to Make Digital Textile Paper?

Digital textile paper, as know as sublimation paper. With a special thermal transfer ink to print a variety of patterns in a special paper above, and then through the temperature and pressure to the pattern and then transferred to the product. It’s amazing, no? Today we are going to introduce how to make digital textile paper.

Sublimation paper is based on the normal based paper, and then making a special coating on it so that under the heat transfer, the patterns and be transferred on to the surface you want.

What’s the Coating of Digital Textile Paper?

Sublimation coating is a functional part of sublimation transfer paper, it plays several important roles at the same time, like absorb the sublimation ink, separate the sublimation dye and the base paper to prevent the sublimation dye from penetrating into the base paper, and absorb the water in the sublimation ink. The third function is the drying process.

sublimation transfer paper In sublimation coating, there is a part named “water removal layer”, this part helps dealing with the drying of the paper, after the sublimation paper is printed. We use water-based sublimation ink, means the carrier is water. Only when the water is gone, all the sublimation dyes stay at the surface, the sublimation transfer result will be as good as you expected. That’s why we always emphasis that the sublimation paper should be completely dry when you transfer it, otherwise the transfer result will not be good, because all the sublimation dye is unable to transferred to the textile when the paper is still wet.

How to Make the Coating on the Based Paper?

dye sublimation paper Sublimation paper coating machine Mainly include single station release paper unit, blade coating, pneumatic open type hot air drying system, back coating wet Mizube, dryer coherent states finishing department, two roll calender machines, single station automatic correction reel, drive unit and electrical control nine parts. Drives with frequency step motor drive. The sublimation coating machine has a simple structure, easy operation and maintenance, loss of paper rate, etc. With this machine, we can make the sublimation transfer paper of high quality.
