Catch the Wave: New Roll Hardness Instruments Shipping

December 30, 2014, EIGHT new ACA Systems RoQ (Roll Hardness) instruments shipped to U.S. customers. Two more instruments should ship in early January 2015. These 10 instruments are part of the wave of new instruments for measuring roll hardness being introduced to the Americas by Technidyne.

The new RoQ has:
  • Rechargeable batteries
  • Integrated touch screen
  • Displays real-time profile data
  • USB data output
  • Barcode reader
  • 1 mm profile resolution
With over 60 roll hardness units already installed in North America by Technidyne, and with many of the new RoQ units on order, Technidyne customers are catching the wave of cost savings associated with modern roll hardness technology.

Technidyne's 2014 Agent of the Year

It is with great excitement to announce Technidyne's 2014 Agent of the Year winner is Equipret in Colombia, South America.  

Omar Mosquera Cortes at Equipret was notified that he is the first winner of this award which will become an annual prize.

This is in recognition of Omar's dedication to his customers as well as Technidyne products and services. Each agent is evaluated equally against the following criteria:

- Account in good standing
- Overall sales revenue
- Overall service revenue
- Overall calibration standard revenue
- Ability and willingness to assist other agents/representatives, when possible
- Commitment to marketing Technidyne products including calibration standards
- Commitment to training
- Ability to independently support customers effectively

We recognize that Equipret has successfully sold equipment, provided service and calibration standards. Omar has also assisted Technidyne in nearby countries and with translating emails and other documents at times, too.  All of this makes Equipret a great example of what Technidyne is looking for as an agent.

As the 2014 Agent of the Year Award Winner, Equipret will receive:

  • a plaque/trophy,
  • a credit on their account, and
  • a free quarterly subscription of calibration standards for 2015.

Congratulations to Omar and good luck to all of Technidyne's Agents as they move forward into 2015.

How Are Brightness and Whiteness Related?

There has always been confusion about what brightness is in the paper industry. Constant questions arise about different versions of brightness including diffuse, directional, TAPPI, GE, ISO, D65… Many previous blog posts and two articles from Technidyne Corporation do a good job of explaining these differences. However, Whiteness has come into greater prominence in recent years as an optical measurement of paper quality. This brings up new questions like, ‘which measurement provides a better representation of visual observations?’ and ‘what is the relationship between brightness and whiteness?’.

Brightness was originally defined in the 1930s as a measurement in the blue part of the visible spectrum defined originally by TAPPI Test Method T452 to monitor the bleaching cycle. Subsequently, it has been used to characterize paper optical properties outside of just bleaching.

Whiteness indices are a compromise between colorimetry and brightness measurement. Colorimetry is a cumbersome but complete three-dimensional description of whiteness, whereas brightness is simple to understand and convey but relates only to the blue portion of the visible spectrum. Whiteness indices have the advantage of being single number quantities that are based on the entire visible spectrum, however, they do reward purple and blue shades of white. This is done to correlate with visual observations of most people.  The chart below shows how brightness and whiteness each relies on a different subset of visible spectrum data.

Relationship Between Brightness and Whiteness
The most basic question in determining the relationship between brightness and whiteness is first, which brightness (directional/UV Level C, diffuse/UV Level C or diffuse UV Level D65) and which whiteness calculation do you want to compare? Literally hundreds of whiteness formulas have been published or applied in different fields over the last 70 years and under a variety of conditions. Just as an example there are whiteness formulas know as Berger, Stephansen, Stensby, Taube, Ganz, Hunter, Harrison, Judd, MacAdam, Croes, Friele, Coppock and Vaeck just to name a few. It is known that whatever whiteness formula is selected that it normally includes a value (Z, Rz, R460) in the blue part of the spectrum in the calculation. However, it is not the same value used in every formula, and, in fact, it is never the brightness value. The weighting of this factor is different in each case. 

So there is a relationship, however, there is no direct correlation between brightness and whiteness. A comparison of the two different indices would have to take into account variables such as geometry, UV level, illuminant/observer conditions, calibration methodology, chemical constituents in the paper and various grades of paper.

Neenah Paper Gets PROFILE/Plus Training

Four members of the Neenah Paper Company team have been in New Albany this week at Technidyne.

The Neenah Paper Company purchased a PROFILE/Plus automated testing system for each mill located in Neenah, WI and Stevens Point, WI.

Ken, David, Nathan and Matt were trained on the operation of the system and were assisted in setting up profiles for their existing product grade structure.

Each PROFILE/Plus automated testing system consists of:

* PROFILE/Plus System Controller
* PROFILE/Plus Caliper
* PROFILE/Plus Roughness & Porosity
* PROFILE/Plus Opacity

We perform a lot of customer and agent training at our facility on topics such as:
   * Calibration
   * Operation
   * Standards
   * Measurement Theory (optical, physical, surface, and process testing)
   * Application
   * Service

Our new Training Room was specifically designed for these activities. Let us know if we can help you with your training needs.

New Standards Format: TAPPI Brightness & Color

Old 1.5" X 2" TAPPI paper calibration tabs
In early 2015, Technidyne will introduce a new format for TAPPI brightness and color calibration standards. 

For over 50 years, TAPPI optical calibration has been performed using small 1.5 inch X 2 inch paper 'tabs'.  The new format will consist of a tablet which is easier to handle and will provide more consistent data since the measurements will come from the same sheet of paper. In past, it was possible that the tabs were each from a different sheet of paper.

The instructions will be:

1. Fold back protective sheet on the bottom of the pad.


2. Place the pad over the sample aperture.
3. Align the standard, matching the marks on the standard with the rectangle on the sample plate of the instrument.

4. Center the instrument light beam in the first circle, parallel to the long direction of the pad.

5. Place the 1 kg backing weight over the are to be measured.
6. Record the value.

7. Lift the pad and repeat steps 3 through 7 for each circle.

NOTE: Do not damage the surface being tested by dragging or sliding the standard across the instrument aperture.

Please let us know if you have comments or ideas on how these will be best implemented. Contact our Lab Manager, Nick Riggs.

There were five employees recognized:
  • 15 years - Scott
  • 20 years - Roger
  • 25 years - Terry
  • 30 years - Perry
  • 30 years - Tim
We are very proud of the fact that our average tenure is 17 years for all employees.  We have added five new employees during the course of 2014.

Improvements in Roll Hardness Measurement

Technidyne started selling roll hardness measurement equipment a couple of years ago.  The instrumentation provided much needed improvements over the Schmidt Hammer which was designed for concrete measurement, not paper hardness. However, our customers were asking for several additional improvements in this technology and measurement area.  The ACA Systems RoQ (roll hardness profiler) provides many advancements.

Improvements in Roll Hardness offered by the RoQ:
  • Rechargeable batteries
  • Integrated touch screen
  • Displays real-time profile data
  • USB data output
  • Barcode reader
  • 1 mm profile resolution
With over 50 roll hardness units already installed in North America by Technidyne, and with many of the new RoQ units on order, Technidyne customers are experiencing the cost savings associated with modern technology.
