Overview
The N9A-2 is a Paint Chart produced by the LENETA brand, designed for black and white without Laminating. Its overall dimensions are 5-1/2 x 10 inches (140 x 254 mm), with a striped pattern at the top of the cardboard, followed by a black area and a white area below. The black area At 60 ° Glossiness Meter measurement, the Glossiness is usually 55 Gloss units, which meets the traditional Glossiness standard of Leneta without Laminating black areas.
Features
1. Adopt black and white non-Laminating design, including striped, black and white test areas.
The black area has a traditional and stable performance of Glossiness, typically 55 Gloss units (60 ° measurement).
3. Uniform specifications, with dimensions of 140 x 254 mm, making it convenient for standardized testing operations.
4. Encasement size is 250 sheets/box, easy to use and store in batches.
Principle
The Paint Chart evaluates the Spreader performance of paints, inks, and other materials by providing a standard test surface with specific Glossiness (black area) and contrast ratio (black and white area). Users can evaluate key metrics such as hiding power, leveling, Color, and Glossiness of materials by observing their performance in stripes, black, and white areas.
Applications
Coating performance test, inks performance test, film hiding power evaluation, Glossiness comparison test
Standards
Leneta Traditional Glossiness Standard
Steps
1. Prepare samples of paint or inks to be tested.
2. Remove a piece of N9A-2 test cardboard and place it flat.
3. Using a suitable coating applicator, Spreader the sample evenly on the test area of the cardboard, covering the stripes, black and white parts.
4. Make the film drying under the specified conditions.
5. Visually or using an instrument (e.g. Glossiness Meter) to evaluate film levelling and defects in striped areas, hiding power and Color performance in black and white areas, and Glossiness in black areas.
Notice
Before testing, make sure that the surface of the test cardboard is clean, flat, and free of creases or contamination.
* When Spreader samples, ensure that the thickness of the Spreader is uniform to obtain comparable test results.
Humidity of the drying process should be carried out under standard temperature conditions to ensure uniformity of test conditions.
* When using the Glossiness Meter measurement, ensure that the instrument is accurately calibrated and the measurement is carried out at the designated location in the black area.
* Products should be stored in a cool drying place to avoid moisture or direct sunlight.
