Computerized Color Matching

Coating manufacturers that make up over 95% of the aftermarket refinishing market have a computerized paint matching system. Spectrophotometer or electronic color analyzer uses electronic technology to read the actual color of the vehicle. It can then communicate with the computer system and paint formula software to mix the correct paint color.

Spectrophotometer

Many spectrophotometer systems can input their color data into a computer. The computer can then use its stored data to help determine how to mix, or if needed tint the paint. Depending on the sophistication of the system, computerized color matching systems may be able to:

• Compare the actual color of the vehicle to a computer stored set of color formulations.
• Make a recommendation on which tint in the formula will move the sample panel closer to the vehicle.
• Automatically keep a record of the mixing or tinting procedure. This will give quick reference.

A good example of the use of an electronic color analyzer would be on a conversion van with four different colors and no available codes. A company which manufacturer’s conversion vans, may use an older Ford or Chrysler color on a Chevrolet. Generally manufacturers put the paint codes on a sticker on the front door or door jamb. Occasionally these stickers may fade, fall off or be omitted after refinishing is completed.

Using the electronic color analyzer eliminates color chip searching and guesswork. The analyzer is placed on the vehicle on the desired color. Taking a series of pictures the analyzer produces a color code, variance chip, or paint formula. This process should take under a minute and can be used on solid, metallic, mica and three stage finishes.
