Paper Week Canada: Feb. 2-5, 2015

Technidyne will have a lot of new technology on display at Paper Week in Montreal, Canada next week (Feb. 2-5) in Booth #3. Some of the products on display will be:

Technidyne Color Touch X - The most sophisticated yet easy to use spectrophotometer built specifically for the Pulp & Paper Industry. It boasts expanded wavelength capabilities (360-740 nm), simple touch screen user interface and 5 nm bandpass. All of these things make the Color Touch X the most repeatable and reproducible color and brightness instrument ever built according to ISO 2469.

ACA RoQ - Portable roll hardness measurement made easy. This device has a built in touch screen display and rechargeable battery for immediate feedback and longer life. ROI on this device is so quick, most customers buy more than one.

Emtec Tissue Softness Analyzer - Already the worldwide standard for objective softness analysis, this instrument provides reliable and consistent results for softness measurement.

Why do I calibrate to CIE Whiteness AND ISO Brightness on my diffuse spectrophotometer?

The short answer is “Fluorescence!”

Now for the longer answer:

In the mid 1990’s Dr. Tony Bristow was elected to be convenor of ISO Technical Committee 6 Working Group 3.  He took it upon himself to establish calibration for UV levels within ISO 2469 conforming instruments.  At the time there were two distinctly different UV levels in use.  The Technidyne Micro TB-1C and other colorimeters tended to use a UV level that was determined by the QTH (quartz-tungsten-halogen) lamp.  Spectrophotometers with flash lamps tended to use full UV (Datacolor Elrepho 2000’s).  When Dr. Bristow and Technidyne investigated the situation, we found that UV Sources “C” and “D65” tended to come closest to matching the two different UV levels. 

The parameter “Brightness” was used at the UV level “C” because colorimeters had a hard time calibrating to tricolor based Whiteness.  That coupled with the fact that at the UV level C, it did not make much of a difference which parameter you calibrated too (Brightness or Whiteness). 

The parameter “CIE Whiteness” was used at the UV level D65 because it gave the better inter-instrument colorimetric agreement between instruments than did Brightness calibration (tri-colorimetric calibration versus single color calibrations with Brightness).

When you calibrate your ISO 2469 conforming instrument with traceable calibration standards from one of the ISO Authorized Laboratories (Technidyne, FPInnovations, Innventia or CTP), a non-fluorescent 90-range standard is used and a fluorescent standard is used. The fluorescent standard calibrates to UV level C using ISO Brightness and UV level D65 using CIE Whiteness.

What's in a logo?

2014 represented the 40th anniversary of Technidyne Corporation. During the year we looked back at a number of developments over the years. One thing that has changed since 1974 is Technidyne's logo.

The multicolored logo seen above has been in use since the early 1990's.  Do you know what the logo represents? There are two things. A prize awaits the first non-employee with the answer.

Preventative Maintenance is Like Insurance

Technidyne has offered Preventative Maintenance (PM) on its instruments since 1985.  This is similar to routine maintenance on your car to make sure it runs well and for years to come.  During a PM visit the instrument 'current' state is checked, the instrument has routine maintenance performed (cleaning, checking voltages, etc.). Finally, the instrument is calibrated and rechecked for its 'as left' data.  Also, during PM visits general maintenance questions can be asked and features can be demonstrated.

Preventative Maintenance insures that equipment is working correctly and will work at the highest level for years. Unfortunately, many people treat Preventative Maintenance like insurance. If they don't use their insurance or have a claim, they don't see the value in it.  Keep this example in mind the next time you consider dropping Preventative Maintenance.

A customer had decided against the normally scheduled Preventative Maintenance to save money.  Later in the year, the equipment was not working correctly and Technidyne was then called to make an Emergency Service Call.  The Service Call cost the customer US$3,751 more than a normal PM would have cost.  The cost was substantially more because additional costs such as labor, airfare, hotel, rental car and training are borne only by one customer. PM is normally performed during a scheduled trip which includes multiple customers who can then share these costs.

Instead of accepting the normal PM, this customer has paid for Service Calls each of the last two years.  The additional cost could have paid for 9 additional PM visits.

Don't risk the headache or the money, schedule your Preventative Maintenance for 2015 now.

Paper Roughness (Smoothness): Terminology

The terms “smoothness” and “roughness” are generally well understood as far as a dictionary meaning goes; however, the use of the terms in test methods is sometimes confusing. In the title of a test method, the term “smoothness” is used when an increasing number is correlates with a smoother surface measurement. An example of this would be the Bekk method, where a smoother surface requires more time for a given volume of air to leak across the surface. Since the reporting for Bekk smoothness is in units of time (seconds), a surface that measures 500 Bekk seconds is smoother than a surface that measures 200 Bekk seconds. If the Bekk instrument was originally configured to report in Bekk flow, which is the reciprocal of Bekk time, then the test methods would categorize it as a Bekk roughness tester.

The two most common instruments that directly report airflow across the surface are the Sheffield and Bendtsen methods. A rougher surface causes higher airflow; therefore these instruments are designated as roughness testers. The Parker Print Surf method is also a roughness tester; however, the reporting (in microns roughness) is a function of the cube root of the measured air flow. In the last few decades, the zeitgeist has been to accurately name the test methods in accordance with the function and not to continue using the manufacturer’s earlier assigned name, if it was not technically correct.

Roughness Testers: Bendtsen, Parker Print Surf & Sheffield

Smoothness Tester: Bekk

TAPPI Grants Technidyne’s Todd Popson “Fellows” Recognition

Technidyne Corporation is pleased to announce that Todd Popson, CEO & President of Technidyne Corporation, will be awarded recognition as a TAPPI Fellow in 2015.

TAPPI (Technical Association of the Pulp and Paper Industry), founded in 1915, has grown into the world’s largest professional association serving the pulp/paper, nonwovens, converting and packaging industries. Being named a TAPPI Fellow is quite an accomplishment. Less than one percent of TAPPI’s members have this title. It is a designation given to individuals who have made extraordinary technical or service contributions to the industry and/or the Association.

Technidyne Corporation was founded in 1974 by current Chairman, Jerry Popson.  The company which is still family-owned and operated, specializes in laboratory and process control equipment for the Pulp and Paper Industry. Todd Popson worked various jobs in Production, Service and Engineering at Technidyne while in high school and college. After graduating from Purdue University in 1991, he spent time in Engineering, Quality and Sales departments before being named President in 1999.  Todd was later named CEO in December 2006.

Within TAPPI, Todd has been an active member since 1992.  He Chaired the Optical Properties Committee for 5 years, and has been a member of the Process & Product Quality Division Leadership for 5 years. He also participates in the Physical Properties Committee, Tissue Properties Subcommittee, Quality & Standards Management Committee, Standards Advisory Review Group, PaperCon Steering Committee, and Papermakers Technical Program Committee. Todd has authored several technical articles and served as a technical editor on submissions to TAPPI Journal.  He is a US Expert to ISO Technical Committee 6 and member of US Technical Advisory Group to TC6, PAPTAC Standard Methods Committee and liaison to CIE (Commission Internationale de L’Eclairage).  Todd is involved in many other industry organizations as well as local charities, school and church committees.

Under Todd’s leadership, Technidyne Corporation has sold equipment into 60 different countries around the world and presented optical properties seminars in approximately 30 different countries.  Technidyne was the 2006 recipient of the Excellence in Export Achievement Award from the U.S. Chamber of Commerce. Technidyne’s calibration standards laboratory is the only ISO Level III Authorized Laboratory in the United States for the issuance of optical standards for the Paper Industry and is the largest such laboratory in the World.

In recent years, Technidyne has been recognized by Greater Louisville Inc. as the International/Global Small Business of the year for 2013 and was a finalist for the 2014 Tri-State Family & Private Business Award.

Mr. Popson will be honored at the PaperCon 2015 Conference in Atlanta, GA, April 19-22, 2015.
