Packaging films are meticulously tested for colour consistency to ensure that they meet the highest standards of visual appeal and brand identity. By subjecting these films to colour testing procedures manufacturers can guarantee that these materials will not get any sign of Metamerism. To ensure that accurate colours will be present in the flexible packaging films, it is important to test them accurately so that no sign of Metamerism will be present in them. Thus, you can easily make use of the Presto colour-matching cabinet. This is one of the high-quality lab testing instruments that is used to test the colour consistency in flexible packaging films and ensure that accurate products will be delivered to the customers.
In this blog, we will discuss brief information about the Presto colour-matching cabinet and why it is important to test the flexible packaging films accurately for colour consistency. So, let us get started!
Flexible films are used in a wide range of industries, including food packaging, pharmaceuticals, cosmetics, and more. Colour is an essential aspect of any product, especially in the flexible film industry. The accurate representation of colour is crucial for manufacturers as it directly affects consumer perception and satisfaction. This is why colour-matching cabinets play a vital role in the production process.
Using this highly accurate colour-matching testing equipment designed by the experts at Presto, manufacturers can easily test the quality of products and deliver them with consistent colours.
This quality testing equipment has been stimulated with real-world conditions that make it easy for manufacturers to conduct quality tests on the materials.
In addition to visual appeal, there are practical reasons why accurate colour matching is crucial in the flexible film industry:
1. Improving Brand Identity
2. Quality Control
3. Ensuring no sign of Metamerism present in products
4. Delivering accurate products to the customers
These are some reasons that indicate you should test the colour accuracy of products efficiently. This allows manufacturers to ensure consistency and accuracy in their products, which is crucial for meeting customer expectations and maintaining a strong brand image. This testing instrument is considered to be the best option to eliminate Metamerism.
Now, let us discuss the features of this quality testing equipment.
The Presto Color Matching Cabinet offers a range of features that make it an essential testing instrument for various industries. Below we have listed the top quality features of this quality testing equipment:
Standardized and Controlled Lighting Conditions: The color-matching cabinet is designed to provide standardized and controlled lighting conditions. It ensures that the viewing environment is consistent, regardless of external factors like ambient light. This standardization is essential for accurate colour assessment and comparison.
Wide Viewing Area: One standout feature of the cabinet is its spacious and wide viewing area. This generous space allows users to examine larger samples or multiple samples simultaneously, making it highly efficient for quality control and colour assessment tasks.
High-Quality Light Sources: The cabinet is equipped with high-quality light sources. These light sources are chosen for their ability to closely replicate natural daylight or other standardized light conditions, depending on the industry's requirements. The use of high-quality light sources ensures that the colours observed are true and reliable.
Multiple Light Sources: Our colour-matching cabinet models offer multiple light sources, including different types of illuminants such as D65, TL84, CWF, etc. This versatility allows users to assess how a sample's colours appear under various lighting conditions, which is particularly valuable for products that will be used in different environments.
Customizable Settings: These cabinets often come with customizable settings for light intensity and timer functions. Users can adjust the lighting parameters to suit specific testing or assessment needs, providing flexibility in their colour evaluation processes.
These are the features of the Presto colour-matching cabinet. Now, let us discuss the technical specifications of this testing instrument.

Using a colour-matching cabinet is an essential tool for accurately testing the colour of flexible films. This specialized lab testing instrument allows you to control the lighting conditions and is considered to be the best solution to solve the problem of Metamerism.
Once you receive the machine, you need to prepare the sample take a sample and cut a specific area from it that the user needs to test.
Take a Master and a sample and place it side by side on the 45o angle fixture.
Now fix the sample on the steel angle fixture using magnets (provided with the instrument).
Turn the machine ON & place the material at the bottom of a viewing booth (sample test area) at the distance from the illuminator required to obtain the specific luminance. The specimen should be viewed at a distance of 450mm to 600mm (18” to 24”).
When viewing a glossy surface, it is necessary to avoid seeing the light source directly reflected by the surface. This may be accomplished when the sample is viewed at 45°.
Now turn ON the required light to see the color difference between the master and the sample. This will help to detect Metamerism. If the matching of both the samples holds well under all the lights. It means that the Dyeing, Printing and colouring of the sample are as per the requirement.
In this way, you can easily conduct colour-matching tests on the materials.
