Measuring Cosmetics with a Gloss Meter
Products that we see every single day have standards of measurement in regard to weight and size specifications – but some industries have to consider additional specifications such as glossiness. In these industries, the reflectiveness of the surface is a factor that’s integral to the product’s success and marketability. One such industry that relies heavily on gloss is the cosmetics industry. Most common cosmetic items must be tested and measured to achieve the desired level of shine.
Reflective Surfaces in Cosmetics
Gloss is important in the make-up industry because every product is specifically created and tailored to be visually pleasing. Products that have a glossy sheen include lip gloss, lipstick, nail polish, mascara, and more. Although there is not necessarily a standard quantitative measurement of gloss for each product to achieve, they are tested and adjusted to obtain the most optimal look. This can be done using one of Konica Minolta’s Gloss Meters.
The Gloss Measurement Process
Even a product as simple as lipstick has a comprehensive gloss test before it reaches shelves. First, a visual inspection of the gloss will be judged by the product development team. They will analyze how the shine of the lipstick looks to the eye and possibly test what it looks like on a model. Next, the gloss will be measured by applying the lipstick to a testing surface. Here is where the Gloss Meter is used. The Gloss Meter measures the amount of light reflected back through the meter. If the number is high, the gloss is high. It also determines the uniformity of the gloss throughout the lipstick.
How the Gloss Meter Works
As stated before, the Gloss Meter measures the amount of light reflected in order to determine the level of gloss on the surface of an object. This can be done at a variety of angles, but the industry standard is 60 degrees. This angle can be used to measure any surface from matte to mirror. Most surfaces are a medium or semi-gloss, so the 60 degree measurement angle is ideal. Konica Minolta’s Uni Gloss 60Plus is a portable and affordable instrument to handle all surfaces. However, if a more tailored reading is necessary, a 20 degree angle will provide better resolution for a high gloss surface. Low gloss surfaces should be metered at an angle of 85 degrees for a more exact measurement. Konica Minolta also has a Gloss Meter with the versatility of measuring in all 3 of these degree ranges – the Micro Tri-Gloss 268.
