With swing-in calibration, primary calibration, ColorTouch® PC software, sample viewing, and optional equipment, the Color Testing Touch PC boasts functionality that is far beyond standard color evaluation including brightness, fluorescence, whiteness, opacity of paper.
- Samples may be measured under 4 different calibrated light sources or 2 user defined sources.
- Device is capable of sampling whiteness under different fluorescing conditions.
- Color data may be calculated with 6 color spaces, 10 illuminants and 2 observers.
- The Color Touch® PC software provides setup flexibility to allow customer specific data presentations.
In today’s world of strict standards and high demands, the data needed to assess whether a product meets customer specification is imperative when making decisions. The ColorTouch® PC can be trusted to accurately gather this vital data.
Count on the Color Testing Touch PC when decisions matter.
When making decisions on whether a product meets customer specifications, the need to have all the data to evaluate the product is necessary. The ColorTouch PC provides capabilities far beyond color evaluation including:
Brightness Testing
The ColorTouch PC is in exact conformance with ISO 2469 and 2470 for the measurement of ISO Brightness. A Certificate of Calibration for traceability to the ISO level 111 calibration is provided with Each ColorTouch PC.
Fluorescence Testing
Samples may be measured under 4 different calibrated sources - C (ISO Brightness), D65 (outdoor daylight), UV-EX (no ultra violet energy), Ganz-Griesser. Plus 2 user-defined calibrated sources. Once calibration of these sources is completed, the instrument stores all settings so that calibration is accomplished internally each time a different source is selected. Spectral data measurements are made with and without fluorescence excitation. This allows complete analysis of the optical brightener's impact on the sample's brightness, whiteness and color shift.
Whiteness Testing
In the paper industry, whiteness is becoming more important as a control parameter. The ColorTouch PC offers the capability of sampling whiteness under different fluorescing conditions. \/Vhiteness values can be calculated under a variety of methods, including CIE/ASTM, Ganz-Griesser, TAPPI and Hunter.
Opacity Testing
In addition to measuring ISO opacity, the ColorTouch PC provides scattering and absorption powers and coefficients along with contrast ratio. Changes in the values as the result of a change in grammage can also be instantly calculated.
Calibration of Color Testing Touch PC
Swing-in
Proper maintenance of the calibration point is the first step any organization should take to ensure that the data generated each day is accurate and precise. The ColorTouch PC utilizes an internal swing-in standard for calibration maintenance on a daily basis. This swing-in standard helps extend the time between primary calibration and improve repeatability and reproducibility.
Primary Calibration
When it comes time to perform a primary calibration, the ColorTouch PC provides an automated calibration process. Technidyne supplies a disk which contains all the calibration data required for the instrument. All the operator needs to do is select the calibration function and follow the directions presented on the screen.
ColorTouch PC Software
Technidyne has designed a Windows™based software package for operating the ColorTouch PC. This unique software provides the operator ultimate flexibility to develop and design specific operational presentations which are exactly what their testing requires. The Designer function of the software will allow for the creation of measurement presentations and functions. Additionally, the ColorTouch PC provides extensive capabilities for analyzing data from several different measurements and evaluating historical trends.
Sample Viewing
Measuring the correct location on the sample can be critical for accurate data. The new approach used with the ColorTouch PC makes this process easier and more functional. The ColorTouch PC incorporates an electronic camera to capture the sample image and presents the image in real time on the computer screen for exact positioning.
