One of the simplest and most effective methods for matching a Pantone color using a DTG printer is to create a color grid or chart and print it onto various styles of shirts, with and without white ink. The chart should be made up of multiple color shades and a reference to the makeup of that color in either RGB or CMYK. Some RIP developers for D2 printers may already provide a color chart, but if not, an internet search could land you one quickly.
If a customer asks for a particular Pantone color, just look up the color in the guide, then hold it next to the various shades of that color you printed on your garment. Whichever is the closest color, use the RGB or CMYK value in your art file noted on the shirt next to that swatch.
It’s always a good idea to let the customer know you may not be able to produce the exact Pantone color, but if possible, show them the closest representation of that color from your printed chart.
