BYK-Gardner (Geretsried, Germany), additive and instrument supplier for the automotive, paint and plastic industries, offers the spectro2profiler, an instrument that measures color and gloss and analyzes the 3D topography of the surface texture.
Previously, grain or surface structure was judged visually or with microscopes. The spectro2profiler is designed to measure color, gloss and surface structure – three parameters that are said to influence visual quality perception.
The spectro2profiler uses a circumferential illumination at 45° with 0° viewing. The large measurement spot with homogenous illumination is designed to provide repeatable and representative readings.
According to Dr. Christopher Groh, R&D project manager, “The spectro2profiler takes multiple images under different illumination directions to estimate surface curvature. As a result, you get objective measures for cell size (mm²) and perceived cell amplitude (P-μm). Different grain types can be easily differentiated – ideal for design and new supplier approval.”
Additionally, the spectro2profiler provides a 2D camera-based reflectivity measurement for structured surfaces. The perceived depth of a leather-like surface is dependent on the reflection behavior on the hills and valleys. Therefore, a 2D reflectivity measurement is aligned with the 3D image data to separate the reflection of hills and valleys. This measurement parameter, reflectivity contrast Rc, is designed for production quality control of injection or slush-molded parts. To compare historical data, the instrument also measures traditional 60° gloss according to international standards.
The spectro2profiler can be used to analyze structures of different applications by using specific algorithms: leather-like for injection or slush-molded parts, coarse paint for powder coatings and fine for plastic parts or fine-textured paint.
The spectro2profiler features a color touchscreen with an icon-based menu. An integrated camera shows a live preview of the measurement spot, which is designed to prevent false readings on imperfections or scratches. The software smart chart analyzes color, gloss and 3D topography data. Pass/fail tolerances for all three parameters can be defined with included standard management. Measurement results are simultaneously displayed in a data table and a variety of graphs that highlight the samples that are out of specification. The 2D/3D analysis is supported with color-coded images to visualize the measurement data.
