The Direct to Garment (DTG) method of printing utilises between 5 and 7 colours of ink during the printing process (depending upon the equipment utilised). Use of RGB files will ensure that in production the brightest possible results will be achieved.
However, it should be noted that some colours within an RGB file may be too bright to achieve when printed on fabric, these are called ‘out of gamut’ colours.
The images below provide an example of how an RGB file which contains very bright RGB colours looks on screen (colour wheels on the left hand side), compared with printed results (colour wheels on the right hand side). Ink on white fabric tends to look brighter and more vibrant in comparison to images printed on coloured garment.
