What is Direct to Garment Printing?

Direct to Garment refers to the process of printing ink direct on the garment or in other words textiles such as fabric, T-Shirts, Hoodies, Tank Tops, etc. The fabrics that can be printed on vary from 100% cotton fabrics to tri blends. The DTG printers use a specialized ink jet technology to disperse the ink onto the textile.

What is the DTG Process?

  1. The DTG process starts with a Pre Treatment. The Pre Treatment is applied before the printing and mats or flattens the fibers in preparation to be printed on and also chemically sets the textile for a white under-base if printing on dark fabrics.
  2. Platen Adjustment; a platen is the garment holding system
  3. Place item to be printed into position on the printer’s pallet, properly aligned.
  4. Load and send your image to the printer
  5. Start printing. Now your printer works it’s magic and begins the print. For DTG printing on dark fabrics a white under-base is printed first. The print for a standard T-Shirt size takes about 3 minutes to complete.
  6. Remove your printed item from the platen or pallet
  7. After printing the ink needs dry quickly in a heat press or a convection conveyor belt system to fully cure.

DTG Images

You can use any images you want for this printing style including full color and vibrant images. The recommended quality is 300 DPI or Dots Per Inch. In comparison a typical image made for the web uses around 72 dots per inch. This term is quite literal, there are 300 dots per inch which will provide a high quality print.

This printing method does not work well with transparent images and you need to use full colors.

Most printers use RGB Images and not CMYK. If an image is created in “CMYK” mode the colors may not be reproduced to exactly as wanted. When prepping your images be aware that when attempting to print in white that RGB 255 is treated as a transparent color. The RGB needs to be set to “RGB=254” for printing white.

Direct to Garment Printing Quality

DTG Printing has extensive color options and can print real photographs and portraits. The quality is the best in the industry. In comparison to the traditional method of Screen Printing the quality is similar but screen printing is unable to print photographs and can only produce designs in limited colors.
