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