How do you check colors before production?
If the textile is dyed, you request a lab dip which is a small swatch that lets you preview the color. You can check the color against the Pantone TCX color you requested.
If the fabric is printed, you request a strike-off which is a printed swatch to check color and scale.
If you are picking from available colors for fabric, trims, or thread, request a swatch or shade card to see your color options.
