Able to be customized or personalized with site-specific hazards, Color Coins are suitable for safety programs. Digital colorization makes it possible to print readable QR codes, realistic colors (including skin tones), gradients, and fine lines onto coins. Logos and images, including faces and fine detail, can be clearly shown, and metal show-through is optional. Digital colorization is available on 1.54 in. coins or keytags in brass, antique brass, nickel, silver, and Sterling silver.
