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

THE COMPARISON OF THERMAL TRANSFER PRINTING MACHINE AND HEAT PRESS MACHINE

Many people who just entered the sublimation printing industry don’t understand the difference between thermal transfer printing and heat press machine. Now I will make a brief analysis for you.

heat press machineThermal transfer printing machines are also known as thermal transfer printing. Thermal transfer printing is an emerging printing process. With its advantages of convenience, speed, dexterity and environmental protection, thermal transfer printing technology has made revolutionary breakthroughs in the field of textile and garment printing and dyeing, and is favored by garment enterprises from all walks of life. The heat transfer machine is one of the thermal transfer printing machines. It can be used to heat all kinds of hot stamping on cotton, linen, chemical fiber and other fabrics. It can also be processed by screen printing, glue, foaming, etc. Cultural shirts, etc.

Thermal transfer is a combination of traditional printing and computer digital, which overcomes the shortcomings of traditional printing, such as small batches, rapid delivery of finished products, complex colors, complicated process, and environmental protection. Thermal transfer does not require plate making, is not limited by pattern, color limit, one-time molding, unlimited style, simple operation, complete functions, just as simple as using a home printer, which largely compensates for the traditional printing and dyeing of cotton fabrics. The industry lacks water resources, environmental damage, high cost of small batch printing and high equipment costs. At the same time, it also brought a strong blow to the development of the traditional printing and dyeing printing industry.

Advantages of Thermal Transfer Printing:

Simple printing steps, accurate position, natural color transition, free printing pattern can realize any pattern printing process, the printing effect is realistic and fine, no need to save the plate making cost, and it is also suitable for printing in traditional way such as rotary net and flat net. Pre- proofing saves money.

Hope you can understand the difference between thermal transfer machine and heat press machine from above. If you have any other opinions about this theme or you have any demand for digital printing equipment, please feel free to contact us.

The Images Are Not Clear At All after Heat Pressing, Why?

   Try to imagine when you print your favorite photo in a t-shirt, but the image is not clear at all. What would you think? You must be disappointed and even want to throw the t-shirt away. Why the images are blurry after heat pressing? How to avoid?

   As an important and easily missed reason, the filters plays an important role is this problem.If there is something wrong with the filter, the ink will outflows brokenly.When you meet this problem, just take the filter away, and just use the ink tube to connect the ink cartridge and the print heads.

   Other reasons can be the temperature or the pressing time of the heat press machine. If the temperature is too high or you heat pressing for a long time, the images will look blurry in the end.

Do You Know the Differences Between Sublimation and Inkjet Heat Transfers?

It is known to all that there are some disadvantages with sublimation. You can only work with light colored garments and novelty items. The dye sublimation ink is very transparent and thus will not have the opacity to cover darker items and using fabrics with a 50/50 mix of cotton and polyester, will result in color that looks dull and faded. Sometimes sublimation prints look soft as well. And finally the inks themselves are expensive.

In general case,standard inkjet heat transfers are much different in that the inkjet ink is transferred with a polymer adhesive layer that encapsulates the ink and gives it stability. Inkjet heat transfers are made to work with most any inkjet printer and ink. It is the polymer adhesive layer that does all of the actual transfer work. The ink is printed onto the adhesive layer and it soaks in a bit. After the ink sets into the adhesive layer, the image is ready to be transferred. The heat press causes the adhesive layer with the image to release from the paper and adhere to the shirt.

On the contrary,inkjet heat transfers paper are easy to make and economical for the home hobbyist. The color saturation is greater and it does not require any special inks or dedicated printers. Some consumer grade papers can be purchased at local office supplies while more professional heat transfer papers are sold by commercial wholesalers. Inkjet transfer paper for dark garments is available but the transfer is often a heavy rubber or cloth material onto which the image is printed normally. This is then heat pressed onto the garment face up. It results in a very heavy, patchy image area which can often cause sweating underneath when worn.
