If u want to print t shirt,there are two printing t shirt printing methods,"dye sublimation and direct to garment, or DTG printing."While both methods result in an image on a clothing article, and they both use inkjet print heads, there are not many other similarities between the two. One major difference, however, is that you can’t get the all over dye sublimation style with DTG – the print heads are just not big enough to handle the process without having to lift the print head, and that leads to poor quality prints. Now, on to the other ways these two methods differ.
Dye sublimation and direct to garment, or DTG printing both use inkjet print heads, the setup is different from the beginning. DTG requires either a custom-built printer that is designed specifically for the item being printed, or you have to modify an existing printer. Whether you are doing all over dye sublimation, or only printing smaller areas, you will be able to choose professional sublimation printers, or you can even use printers right off the shelf for smaller items. These printers will not need to be modified, so you’ll not only save money, you will also be able to get started right away.DTG and all over dye sublimation both use inkjet systems that are run by graphics software. This means you’ll be able to create an endless array of colors with either method. However, DTG uses only four colors, while sublimation printers are available in four, six, or eight color models. These color options are the base colors that will be combined to create the designs, which means the more color options you have available, the more color combinations and preciseness you’ll be able to create in your designs.
Different fabric are designed for different printing options,DTG works best with cotton, while all over dye sublimation works better with polyester. You can use either method on other fabrics, or even blends, but the color results will not be as bold and vivid. For those of you cringing at the idea of polyester, keep in mind that changes in textiles allows for super soft polyester that feels quite similar to cotton.DTG and all over dye sublimation provide very different results, even though they start with the same type of printing process. While one type may work better in some situations, the true test depends on which one you can afford, and what you plan on printing.
