Gloss has been defined as ‘The attribute of surfaces that causes them to have shiny or lustrous, metallic appearance.’
Manufacturers design their products to have maximum consumer appeal. Traditionally, a high gloss finish is often perceived to be a higher quality product and can therefore command a price-premium.
It is for these reasons that many manufacturers monitor the gloss of their products to ensure batch-to-batch consistency of their products.
Example – Evaluating high clarity blister packs
STEP 3: Different values were measured along the measuring beam axis (sample in line with axis) to values measured across the sample (sample at 90 degrees to measurement axis).
Example – Blister Packs
Observations of results
It was possible to obtain accurate peak (actual) gloss measurements for each part.
It may also be useful to consider a custom location adaptor for the samples, this can be 3d printed to suit each part which should improve accuracy due to improved location.
For curved surfaces, the correct gloss value is the peak value identified on the sample. Continuous read mode on the Novo-Curve 4 greatly simplifies this process.
For improved gloss control, calibrate on a standard that matches closest to your sample. Additional standards are available from matt to mirror finish.
The optional footswitch enables the user to easily manipulate the sample for measurement.
Measure samples too small to be measured with a standard glossmeter.
For an exact fit for small complex shapes, a custom cutout enables the sample to measured in exactly the same spot each time.
