Something You Need Know About Heat Press on Dye Sublimated Fabrics

What is Dye Sublimation?

Most polyester fabrics, such as many of the popular “Performance Garments”, are dyed using a sublimation process. The dye sublimation process uses high heat to permanently fuse the colorant into a polyester fabric.

Heat press machine serves two critical functions in this dying process. First, the heat causes the pores of the polyester fabric to open up, so the material can accept the dye. And second, the heat converts the solid ink dye on a transfer sheet into a gas.

Under pressure of the heat press, the gaseous dye is forced into the open pores of the polyester. As the temperature drops, the pores close up capturing the dye inside of the bonds to the substrate.

The sublimated color is very durable because the dye becomes an integral part of the fabric, rather than a colorant on the outside of the fibers of the fabric, which can bleed and fade. Sublimated fabrics can be washed again and again, without losing the vibrancy of its color.

Dye Migration Can Discolor Heat Transfer Appliques

There’s one slight catch, though. When you heat press an applique onto a sublimated garment, the high heat can release the dye in the fabric. These dyes can then migrate and discolor a heat transfer vinyl applique.

Discoloration resulting from dye migration does not occur immediately. Instead it is a gradual process, which may take as long as 72 hours to occur. For example, a white applique heat pressed onto a black sublimated garment is likely to turn gray over time.

How to Avoid Dye Migration During Heat Transfer Printing?

With the growing popularity of athleisure and performance wear in the sporting goods industry, we are seeing more and more of the garments containing materials that present a challenge to the apparel decorating community in regards to heat transfer printing.

Sublimated apparel adds trouble to the printing mix because of the special dyes used during that specific printing process. In the end, when apparel decorators are trying to print on these types of fabrics, especially polyester, the apparel dyes tend to “migrate” through the finished design that was added to the garment.

What does this mean? Well, for example, your white letters on your red shirt end up being pink instead of white. This is known as dye migration.

What is Dye Migration and What Causes It?

Dye migration is when the ink “bleeds” through the ink or transfer that was applied to the garment. This happens because of the heat that is needed to cure the ink or apply the transfer during the screen printing or heat printing process.

However, the same heat will also “activate” the dyes used for coloring the apparel, especially in polyester fabrics. This will allow the dyes in the garment to start penetrating the ink used for decorating. It may not be visible immediately, and many times will become visible within several days after the decorating process occurs.

Dye migration is also very common among sublimated apparel. During the sublimating process, dyes are actually infused into a garment with the dyes being in a gaseous state. Heat will also activate these dyes back into a gas state, allowing the dye to bleed through your ink.

It is a similar concept of when you wash your clothes. If you add a red shirt in with your white shirt, especially in hot water, your white shirt will come out pink. So the most common culprits are the polyester fabric types, bright colors, and the dye process that was used, such as sublimation printing.

If you have these combination of factors, take careful measures to avoid dye migration from happening.

So Easy! 5 Tips for You to Sublimate Mugs Successfully

Sublimate mugsMugs are so popular in the market, it is due to it’s cheap and personal. When it comes to sublimating mugs, you will want to make sure that you get everything on point, to avoid wastage. To ensure that you hand out your best work, here’re five tips that you should use:

1. Checking completion of cooking

If you want to check if you have cooked the mug properly or not, all you need to do is remove some of the paper from the corners. Take a close look to see if the image you sublimated is of high quality. However, if you are unable to remove the corner portions of the paper, you will need to cook the mug for a longer time. Sometimes, you might have to increase the pressure, as it wasn’t enough.

2. Cooling after completion of sublimation

Once you have completed sublimating the image on to the mug, you will have to remove the transfer swiftly so that you can start the cooling process. The reason why you need to cool the mug is to bring the sublimation process to a complete halt. If you have to cool a ceramic mug, you can keep it in water along with the transfer at room temperature.

3. Correct measurements

When you want to sublimate the image correctly on the mug, make sure that you measure between the tapering parts and adjust the templates accordingly. The reason is that you won’t get a proper print if you directly sublimate the print on to the tapered section.

As there won’t be proper pressure and contact at the handles of the mug, make sure that you leave at least ¾ – inch gap at the bottom and top of the handle for a good print.

To cook the mug properly, you should make sure that the sublimation oven temperature is 400 degrees. As most sublimation ovens don’t display the right temperature, it is better to measure it manually, with the help of a thermometer. When the temperature is low, your mug will be under cooked.

5. Trim bottom and top edges of the paper

To prevent the paper from going into the mug’s tapered portion, you should trim the bottom and top. When there is excess paper, it will wrinkle, affecting the quality of the image.

Isn’t that easy to use these five tips to sublimate mugs successfully?

A BRIEF STEP-BY-STEP GUIDE ON HOW TO OPERATE HEAT PRESS MACHINES

According to functions, we can divide heat press machines into two types – basic and professional. But whether you’re using the basic or professional heat press machines, they are basically operated the same way.

The basic heat press machines are good for small jobs and home use. They’re much more affordable. The professional heat press machines are geared for making bulk orders. They have a much bigger platen (metal board) for a bigger working area to cater large garments. The professional heat press is also complete with more sophisticated time, temperature, and pressure settings.

 

Here’s a brief step-by-step guide on how to operate heat press machines:

 

1.Turn on the power by flipping the on/off switch

2.Turn the thermostat knob to the right until you see the red heating light

3.When the thermometer indicates the desired temperature for your transfer, turn the knob back to the left until the heating light turns off. The heating light will go on and off to regulate your desired temperature

4.If your machine has a digital timer, press it to start the timer and when you hear the alarm, press stop to reset

5.Lift up the handle to open the press

6.Lay out t-shirt and lay Transfer Paper onto shirt facing down

7.Bring the handle down. The handle should lock firmly in place

8.Set the timer based on the instructions on your Transfer Paper

9.Lift the handle to open the press

10.Peel the Transfer Paper from the shirt

11.Allow at least 24 hours for the print to “lock” before washing the t-shirts

 

These all above are my share about the steps of operating heat press machines. Hope my article can be useful to you. If you have any other needs or questions welcome to contact us at any time. We will provide you the best quality product and service. Thanks for your reading.
