Model 600 Imaging Spectrophotometer Introdcution Video Transcript
In this video, I am demonstrating a typical reflective color measurement scenario for the print industry. What would the print industry currently use to measure something like this? They have a device called a Spot Spectrophotometer, or Spot Spectro. There are hundreds of them and a hundred different kinds on the market, capable of measuring color at a very specific point. The point, or spot, may be somewhere in the order of a 32nd-inch diameter; so we're talking about very small spots here. What would a printer do for an example like this? The customer(operator?) would specify a handful of locations on their print in which they would use their Spot Spectro and they would go around and take specific measurements, then fill in a table, compare those results to an acceptable range or acceptable limits and based on those handful of points, make the assumption that this print is in or out of spec. Or the printer also can use the color bars located at the bottom of the print; or on the edges of packaging you will find these. And that is where the printer can analyze these color bars and infer or assume based on these color bars, if this color final print is in or out of specification, indirectly.
