Now let’s take a look at the history of digital textile printing and how it became an industrial printing method:
History and Evolution
The development in digital textile printing came as a result of inkjet printing technology which was invented in 1968. But it was not until 1990s that inkjet printing became a widespread printing method to print on papers. The evolution in inkjet printing technology led to the production of digital textile printers which made it possible to print on fabrics. By early 2000s, digital textile printing became a popular printing method for printers all over the world.
Today, you will find plenty of digital textile printers in the market that can print on all different types of mediums and substrates including canvas, paper, vinyl and clothes.
Now that you have an overview of the digital textile printing and its history, we will explain the technique involved in digital textile printing and how it works on different fabrics.
In non-technical language, digital textile printing technique is about printing any artwork onto a fabric using inkjet printing technology. But that is a narrow definition of a broad printing method that has various facets. Basically, digital textile printing falls under two printing techniques: (1) Sublimation digital printing and (2) Direct digital printing. Let’s discuss each of them one-by-one.
Sublimation Digital Printing
Sublimation digital printing is a common textile printing method that makes use of heat to transfer dye onto the fibers of a fabric. It is an endothermic process that absorbs heat energy to convert a solid dye into a gas that later fuses into the fibers of a fabric. This method can be divided into three steps. Here they are:
(1) Create an Artwork
The first step is obviously the artwork creation process. At this step, you prepare a design that you want to print on a fabric. The design is based on a RIP format and is sent to the printing stage in the second step.
(2) Get the Print
In the second step, you get a mirrored print of the artwork using a sublimation printing paper that has one coated side. Once you press the print button on the printer, the artwork will be transferred onto the coated side of the sublimation printing paper.
(3) Transfer the Print onto the Fabric
Finally, you put the sublimation printing paper onto the fabric and get the print on it with help of a heat transfer machine. There you are! You got the print.
Direct Digital Printing
Direct digital printing works similar to paper printing that you do in the office. The only difference is the medium since you using a fabric instead of a paper. A direct digital printing is divided into four steps. Here they are:
(1) Perform Pretreatment
Pretreatment is essential to create durable print that firmly sticks to a fabric. Pretreatment is done with a liquid solution that you apply on the fabric. It helps keep the ink onto the fabric and increase its coverage on the fabric.
(2) Prepare the Artwork
In the second step, you need to create an artwork and then RIP it to make it printable on a fabric.
(3) Print the Artwork
In the last step, you will put the fabric onto a printer. The coated side of the fabric will be inserted into the printer belt which will then print the design onto the fabric.
(4) Cure the Ink
The printed fabric has wet ink which needs to be dried using a dryer. A dryer is attached with a digital printer and also comes as a separate unit. Cure the ink using the dryer so that it doesn’t smudge or come into contact with the fabric. Finally, you got the print!
Now, we will look at some of the advantages that digital textile printing has over other printing methods.
Advantages of Digital Textile Printing
Apart from being a simple and hassle-free form of printing, digital textile printing has many other advantages over other printing methods. Here they are:

In comparison with other printing methods, it uses less ink and power to create a print and there is no use of water in the entire process. In other words, you bear less production cost for a single print which makes it a more cost-effective printing method.
