Transfer printing describes two different types of printing: Heat transfer printing and sublimation. They both have their pros and cons, but they both tend to be more suited for different needs. There is still some ambiguity on sublimation and how it works, so we are going to take a look at the most frequently asked questions and try and provide a little more clarity.

Heat transfer printing is done using a specialist paper that is called transfer paper. You can use a standard inkjet or laser printer to print onto this paper with your normal inks. You then place the paper onto your clothing and use a heat press, or in some cases, you can use an iron, and peel away the paper.
Your design will then be stuck-on to your garment, and you will be able to see the transfer. You can use most heat transfer paper on a variety of fabrics, including most poly textiles and natural cotton. You can print on both light and dark coloured garments.
Sublimation is a modern digital printing technique that is increasing in popularity. Search volume has increased by around 115% worldwide since , according to Google Trends. It uses sublimation paper and heat to print your design.
We advise that you use this on fabrics that are 85% poly or more. This is because it is the poly fibres that open their pores to accept the dye. You can use a lower composition, however, your colours will be affected. You&#;ll end up with more of a &#;vintage faded&#; look. You can also print on hard surfaces with a poly-coating, such as keyrings, jigsaws, mugs and so much more.
Sublimation transfer paper is a specialist paper that is used exclusively in sublimation printing. Made using a paper substrate, which is broadly based on a normal paper. A special coating added to the paper holds the dye sublimation inks. The coating includes around 35% silica and 5% binder, based on the weight of the paper when it&#;s dry.

Sublimation doesn&#;t use any liquid in the process. Inks heated from their solid-state on the sublimation paper, convert straight to a gas. It is a printing method that bonds to poly fibres, and because the poly fibres have been heated, the pores expand. These open pores then allow the gas into them, which then fuses to the fabric itself, before resuming its solid-state. This makes the ink part of the fibres themselves, rather than just a layer printed on the top.
Sublimation is a two-step process. Firstly, you need to print your design onto the sublimation paper, using specialist sublimation dyes. The image would need to be mirrored, but don&#;t worry about that, Contrado does that for you when you place your order, so all you need to do is create your design as you want it to look when it&#;s finished.
Then you need to press the design from your paper onto your t-shirt (or fabric or surface). This is done using a heat press which applies either heat and pressure, or heat and a vacuum. Once pressed, simply remove the transfer paper, and voila, your t-shirt is printed.
Sublimation is best suited to white or light-coloured fabric bases. You can use it on darker shades, however, it will affect your colours. White ink is not used in sublimation printing. White parts of the design remain unprinted which shows the base colour of the textile.
The benefit of sublimation over heat transfer printing is that there is a much broader range of colours. This means that you could print your background colour onto the fabric rather than use a different coloured fabric, and because of the advanced printing methods, the material would feel exactly the same.
Sublimation paper holds an enormous amount of moisture and humid air is not great for it. Exposure to humid air causes the sublimation paper to absorb it like a sponge. This results in image bleeding, uneven transfers and colour shifting.
Heat transfer paper is also sensitive to humidity. The inkjet or laser printing is more prone to dotting and colour bleeding if there is excessive moisture in the paper, and as this form of printing applies a film, rather than being textureless, you may find that the transfer is not flat, or curls or peels at the edges.
When working out which side to print on your sublimation paper, it is important that you print your design onto the bright white side. If you order sublimation paper from Contrado already printed with your design, you will be able to tell which side is the right side.
You&#;ll find that your colours look pale on the sublimation paper. This is completely normal and isn&#;t what the finished press will look like. Once transferred to your medium your colours will come to life! Another benefit of sublimation over transfer printing is that there is a much bigger range of colours.
You can&#;t reuse your thermal transfer paper, whichever type you use. Although with sublimation paper, you may find that there is some ink remaining on the paper, it will not be enough to make a good-quality print.

With transfer paper, the iron&#;s heat melts the plastic lining on the paper, which transfers the ink to the fabric, as well as the plastic from the paper. This would be impossible to re-use.
There are some common mistakes when it comes to designing your own t-shirts, other clothing and items.
*remember, if ordering through Contrado, we will do this for you, it&#;s important that you don&#;t do this step.
We always suggest testing on a small piece first, to ensure that you get the right amount of heat and pressure, before printing your full design.

Sublimation printing is used to transfer images onto a variety of materials from t-shirts to ceramic mugs. It allows you to create personalized items from photos, graphic designs, and more. Sublimation is especially well suited for printing on clothing, as the ink is assimilated into the fibers of the fabric. You can&#;t feel the image on the material, making it more comfortable than screen printed designs.
In order to try sublimation printing, you&#;ll need a specific type of transfer paper, a sublimation printer, sublimation ink, and a heat press. The image is printed onto the sublimation paper, then transferred to the garment with a heat press. In order to master sublimation printing, it is necessary to know how to use the transfer paper properly. Here&#;s how it's done.
Here&#;s the process for sublimation printing broken down step by step:
Here are some additional tips to help you print successfully with sublimation paper:
Remove backing. Be sure to remove the protective backing from your sublimation paper, if there is one. Some types of sublimation paper include a clear layer that needs to be removed before printing the image onto the paper.
Secure your image. When you are ready to transfer the image from the sublimation printer to your garment, secure the paper with heat resistant tape or adhesive spray. This will prevent it from shifting as the heat press is applied.
Trim the paper. After you print the image onto the sublimation paper and it has fully dried, trim around your image before pressing to prevent a square shape from being visible on your garment.
