Sigma-Nip records nip width, making older methods, such as carbon paper and embossed foils, obsolete.
Sensor Products has claimed the Sigma-Nip is faster, more cost effective, more accurate and more durable.
The product consists of a chain of sensor elements and Windows-based software. When placed between two contacting rollers, the sensors record and assimilate nip width readings on a laptop while it is being viewed.
Electrical engineer Mike Estelle, who works in Agfa Graphics' platemaking division, endorsed Sigma-Nip.
"In the past, we adjusted air pressure for nip but didn't have the feedback mechanism to ensure we were doing this precisely," Estelle said.
"Through Sigma-Nip, we have established a baseline for our rollers and we will use Sigma-Nip frequently throughout our plant."
