Yes, we skipped exhibiting at Converters Expo last year, but we are back. After the hiatus in trade show attendance, it’s good to see Converters face to face. Better yet, we enjoy helping Converters solve problems that might seem unsolvable. 

This year we are sending two of our experts to work with you in solving your problem in web guiding and monitoring. Whether it’s an issue with edge, center or line guiding in a specialty area, or a difficult monitoring application, we have developed the technology to solve many problems in the industry.

There are converting operations that require alignment of the web material to the centerline of the converting machine. In this case, you will usually find a two sensor setup for this type of guiding. This application is referred to as center guiding.

In 2020 we hosted a webinar on web guiding applications and advanced web guiding concepts as a continuation of the educational series web guiding fundamentals. This webinar was the follow up on our seminar on Web Guiding Fundamentals, presented earlier that year, and commented in a series of blog posts in 2021. We would like to share some comments on the points presented in this webinar in the form of a series of blogs.

Another Option in Contrast Guiding when there is no Feature that could Mimic a Line.

In a previous post on contrast guiding we discussed using the negative space between straight edged labels as an intermittent linethat can be tracked by our sensor/camera and control system for web guiding applications. However, our system allows for other ways of using a contrast application that do not require a negative space that has characteristics of a line for the purpose of tracking.

A Very Special Option for Contrast Guiding and Monitoring

Couple of weeks ago we made an announcement about our new Roll-2-Roll^® Sensor product line ODC. We also announced the transition plan for existing customers using WPS to eventually transition to ODC. This caused some confusion and in this blog  we will address this.

Contrast sensing allows for a variety of applications to guide or monitor your web. These applications help you eliminate the need for a printed line. Eliminating the printed line saves the cost of ink to print the line and the web material where the line would be printed. 

A contrast is any visible printed, embossed or laminated feature on a web. Most of the time, a visible feature is understood to be visible with the naked eye. However, it can include UV printed features that are not visible to the naked eye, but are detectable for a UV type of sensor or camera.
