The purpose of measuring the surface gloss of paper is to evaluate its appearance quality and application fields, because the surface gloss of paper is closely related to its appearance effect and application fields. The surface of high-gloss paper is smooth, bright and clean, without blemishes, and has good reflective properties, which can improve the visual effect and value of printed matter; while low-gloss paper is suitable for stationery and packaging paper that require simplicity and simplicity. At the same time, measuring the surface gloss of paper can also help manufacturers monitor product quality, discover problems in the production process in time, and make adjustments and improvements, thereby improving production efficiency and product quality stability.
Gloss meter is one of the commonly used test equipment in paper printing, which can be used to measure the surface gloss of paper. The following are the steps of using a gloss meter to test the glossiness of paper printing:
Prepare the sample: Cut a flat sample from the paper to be tested, making sure that the surface of the sample is free of any scratches or stains.
Adjust the gloss meter: According to the operating instructions of the gloss meter, adjust the instrument to the appropriate test mode and light source.
Place the sample: Place the paper sample on the gloss meter test stand, and calibrate the sample according to the instrument instructions.
Run the test: Start the gloss meter and follow the instructions in its operating instructions to run the test. During the test, it should be ensured that the instrument and the sample are in a stable state without moving or shaking.
Record the results: After the test is completed, the measurement results are recorded and analyzed. Generally, a gloss meter will provide a digital readout that represents the gloss value of the sample. Higher numbers indicate higher gloss.
Repeat the test: To verify the accuracy of the results, the test can be repeated several times until consistent results are obtained.
NBCHAO reminds you: Different models of gloss meters may have different operating procedures and requirements, so be sure to read the operating instructions carefully and operate according to the requirements before use. In addition, different printing materials and printing methods may also affect the test results, so the test conditions should be strictly controlled before the test to ensure the accuracy of the test results
