DTG also known as  Digital Garment Printing  or Direct To Garment printing is the latest technology in fabric printing. It is printing an image directly onto a fabric without the necessity of positive films, screens, set up or anything else that is required for screen printing.
The ECO friendly water based ink is printed directly onto fabric which results in exceptional “soft feel” print as well as offering more flexibility than screen-printing in terms of color variation and turn-around time (especially for smaller orders). The quality of your image / design has a direct effect on the outcome.
Beware that there are many ordinary paper printers modified to print on fabric but only the printers that are made for garment printing would produce quality prints and just like any other equipment in the market, there are low quality and high quality ones hence we have chosen the best in the industry to guarantee your satisfaction.
DTG Garments:
printers are made to print on 100% cotton fabric. The more mix in your fabric, the more fade out / washed out look you will get . Although some people like this outcome, they say it is a nostalgic look. We print on any fabric other (Tri-Blend, 50/50, Burnout, ...) other than 100% polyester such as sport jerseys.

DTG files:
Files have to be 
* 200 DPI or higher resolution
* To the size that you want them to be printed
* Transparent background.

DTG Pricing:
It is all about the ink coverage and not number of colors in your design therefore we need to:
1- See your design and know the size "in inches".
2- What color shirt.
3- How many Shirts per design.

Here are some actual samples and of course there's a lot more but we have promised to safeguard our client's designs. 
DTG with no white base:
An image can be printed on a white fabric without needing a white base since the fabric is white. Imagine painting a white wall, you wouldn't need a white under base. You can also request no white base on very light color fabric (see images of Texas state below). The only issue is that the color of the fabric will change the tone of colors in your design, also the white area of your design will be the color of the fabric.
The darker the fabric, the less you'll see true colors therefore we recommend using a white under base on color fabrics to show your design in its best possible way.

White background vs. Transparent background

DTG Printers print anything that is in the image, especially the white background of a pictures that you may not want. Therefore your design must have a Transparent Background. Adobe Photoshop or Illustrator are the best to adjust your designs.
