Vteke Color Meter can be used for quality control in many applications
Leather, Packaging, Ceramics, Rubber, Textiles, Printing, Plastics, Paint, Construction, Automotive, Glass, Foods, Medical, Cosmetics, Electronics and more.
When using a color meter to measure powder samples, the data changes to reflect the powder density and surface conditions. To avoid a large deviation, special measuring methods exist, such as taking a specific amount of powder into a specially designed container (powder holder A-10) or keeping the surface properties consistent.
(The image shows how to transfer the powder to an A-10 for measurement.)
For a large object, choose a colorimeter with a bigger measure aperture so that the surface of the object is averaged and the repeatability of data is more accurate.
Measuring a Wet or Uneven Surface
If the surface is wet or uneven, using normal measurement instruments will not result in accurate results and contaminants may affect the instrument. Always use a protective glass plate when measuring a moist surface. The protective glass plate can be used in conjunction with a large aperture to measure objects with uneven surfaces by flattening the uneven surface.
Measuring a Textured or Patterned Surface
When measuring textured or pattern objects, choose an instrument with a large aperture. The measured data changes according to shifts in the measuring position so you need a color meter or spectrophotometer with a large aperture to repeat the measurement several times in different positions before calculating the average.
Another option is to use an instrument with a 45/0 geometrical optics structure and circular lighting to avoid the impact of catoptric light on texture. This is especially important when it is used in leather, automobile interiors and furniture applications.
Special Measurement – Multiple Measuring Apertures
The 4mm aperture is ideal for measuring colors in small areas, on an arc and on other types of special surfaces. Examples of color measurements with a 4mm aperture include: plastic products with a 20mm diameter, convex and concave surfaces devices used in security facilities and high-end glass surfaces.
The 8 mm aperture can be used in any industry to easily meet the color requirements for many materials and types of measuring. This size aperture delivers convenient color communication across multiple industries because of its proven stability and reliability when measuring color.
The 16mm aperture is designed to evaluate the color of objects with texture, uneven surfaces or extensive color variation. It’s also recommend for large objects. For these products, a 16mm aperture is more accurate and helps users consistently control the color quality.
