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.

What’s the Difference Between Heat Transfer Printing vs Screen Printing?

rotary heat pressIf you are in digital printing areas, you’re probably wondering what the difference is between all these very similar printing options – like heat transfer printing vs screen printing. In this article, we’ll help you decide which printing process is best for you by breaking down the differences between these two common printing types.

When a design is produced using the screen printing method, actual screens are used in the process! Essentially, this screen is cut to make a stencil for the design. Ink is then spread over the screen, passing through to the object underneath only in the areas you want it to be. Only one color per screen can be used – so depending on the number of colors in the design, you’ll need multiple screens to produce the final item.

The heat transfer printing method applies custom designs to items like t-shirts or tablecloths through a process that uses a combination of heat and pressure. Common kinds of heat transfer printing include vinyl heat transfer and digital print heat transfer. With the vinyl heat transfer process, a machine is used to cut out designs and letters in pieces of colored vinyl. A heat press is then used to transfer each vinyl color of the design onto the object being printed. With digital print heat transfer, the desired graphic is first digitally printed on special heat transfer paper using a solvent ink. This type of ink allows the design to be transferred from the paper to the item being printed when pressed with heat. With both these types of heat transfer, a heat press machine will be needed to transfer the graphic, either vinyl or digitally printed, from one surface to another. It’s the magical combination of heat and pressure that transfers the design!

WHAT’S THE PRINCIPLE OF THERMAL TRANSFER PRINTING?

If you got into the digital printing industry, you must have heard of thermal transfer printing. The principle of thermal transfer printing is somewhat similar to the transfer printing method. Today, we will introduce the principle of it.

In thermal transfer printing, a pattern is first printed on paper with a dispersion-containing dye and a printing iheat press machinenk, and then transfer paper is stored for use in a textile printing factory.

When the fabric is printed, the transfer paper and the unprinted face-to-face are pasted together through a thermal transfer printing machine, and the dye on the transfer paper is sublimated and transferred at such a high temperature at a temperature of about 210 ° C (400 T). On the fabric, the printing process is completed without further processing. The process is relatively simple and does not require the necessary expertise in the production of roller printing or rotary screen printing.

Disperse dyes are the only dyes that can sublimate, in the sense that they are the only dyes that can be thermally transferred. Therefore, the process can only be applied to fabrics composed of fibers having affinity for such dyes, including acetate fibers and propylene. Nitrile rayon fiber, polyamide fiber (nylon) and polyester fiber.

In thermal transfer printing, fabric printing plants purchase such printing paper from highly specialized printing paper manufacturers. Transfer paper can be printed according to the requirements of the pattern designer and the customer (off-the-shelf patterns can also be used for transfer paper printing). Thermal transfer printing can be used to print pieces (such as border printing, chest embroidery, etc.). In this case, a specially designed pattern is used.

sublimation printing

Thermal transfer printing stands out as a complete fabric printing method from the printing process, thus eliminating the need for large and expensive dryers, steamers, water washers and tenters. Since the printed paper can be inspected before printing, this eliminates the inaccuracy and other symptoms. Therefore, thermal transfer printing fabrics rarely appear defective. If you are considering to choose a good printing method, thermal transfer printing will be a good choice.

What Is the Perfect Heat Press Machine for You?

   When you buy a good inkjet printer at home, the next step is to find a perfect heat press machine (unless you want professional factory to help you). But how to make sure you can buy the heat press machine? heat press machine

   Size is the first factor. The size of the heat press machines are various on the market. You should know the size of your products, and it will be better to take the future into consideration.

   Consistent heat is an important indicator to judge the quality of the heat press machine. Heat presses need to be heated to about 400 degrees fahrenheit for sublimation inks to transfer from the paper to the polymer fibers. This transfer has to be smooth and even for the process to work properly and for the image transfer to be consistent from one pressing to the next. heat press machine      Consistent pressure is another indicator to just the heat press machine quality.  A quality heat press has a heavy platen that generates enough weighted-pressure

   Heat pressing is not a complex job, as long as you choose the suitable heat press machine, everything can be easier.

What are the supporting materials for roller drum heat transfer machine?

Introduction of materials for roller drum heat transfer machine.

The dilution ratio of hot avulsion type release agent is 1:1. The release agent with diluent must be stirred evenly before use.

D. It is advisable to use 250-350 mesh screen, can be printed per kilogram of about 130 ㎡, printed twice is preferred.

Three advantages of heat transfer printing machine, can you guess?

Heat transfer printing is a new printing and dyeing technology which is emerging in the world in recent years. First, use advanced printing techniques to dye special prints (waterborne or oily), print all the necessary patterns on special paper to make transfer printing paper with various patterns, and then on heat transfer printing machine. The transfer printing paper printed on the side of the printed pattern and the printed fabric, through the heat and pressure, using the paper dye sublimation, transfer to the printed fabric, in the printed fabric to form the required patterns. Thermal transfer printing machine is more and more popular nowadays, and its three advantages cannot be separated.

1. Simple steps.

It does not require plate making, printing, repeated color steps, screen printing and heat transfer methods required by various types of tools, materials. Using a printer, you only need to prepare an ordinary computer. One operator can operate the printing operation completely independently, save manpower and material resources, and the way is simple, instant desirable. The experience requirement to operator is low, want to know simple picture processing software to be ok only.

2. Avoid damage.

It can be printed not only on tough crystal, stone, metal, glass and other materials, but also on soft leather, cloth, cotton and other materials. It can be printed on inorganic materials, or on organic materials with complex composition and variety. With more and better compatibility for materials, the use of the vertix printer avoids the problems of screen printing, water transfer material selection, as well as the damage of heat transfer to other organic materials such as leather, cloth and cotton. It caters to diversified market demands and can provide more comprehensive production services for users.

3. Avoid deviation.

Printer is no longer the traditional printing mode and method, is no longer a simple manual operation of the past and printing craft, with high technical content of computer generated, and the combination of automatic control technology for the better, can be very precise on the printing area and position, to avoid the manual printing house in the position of the deviation problem. As it is a one-off multicolor printing, there will be no matching problem. These advantages can also be combined with engraving and etching in a very effective way, such as printing beautiful images in the engraving area, or precise etching after printing, making good breakthroughs in the engraving industry.
