Whiteboard paper is a commonly used printing paper material, usually used to make book pages, advertising leaflets, picture albums, magazines and other printed matter.

Performance of detection
It needs to detect the following major performances:

Whiteness: the whiteboard paper needs to have a high whiteness to ensure the bright color and clear image of the printed matter. The detection of whiteness can be carried out by measuring the reflected brightness and chromaticity coordinates of the paper surface.

Printing quality: The printing quality of whiteboard paper includes image clarity, color reduction and printing speed. The inspection of printing quality can be carried out by checking the printing effect, line clarity, color reduction and other indicators of printing.

Thickness and uniformity: The thickness and uniformity of the whiteboard will directly affect the printing effect and quality of the printed matter. The detection of thickness and uniformity can be carried out by measuring the thickness, density and basic weight of the paper.

Performance test and test method for whiteboard paper

Strength: The whiteboard paper needs to have a certain strength to ensure the stability and durability of the printed matter. Strength detection can be carried out by measuring the tensile strength, flexural strength, compressive strength and other indicators of paper.

Smoothness: the whiteboard paper needs to have a certain smoothness to ensure the printing effect and quality of the printed matter. Smoothness detection can be carried out by measuring the gloss, smoothness, roughness and other indicators of the surface of the paper.

Environmental protection: white board paper needs to meet environmental protection standards, does not contain harmful substances, no pollution to the environment. The detection of environmental protection can be carried out by measuring the volatile organic compounds, heavy metals, chloride ions and fluorescent whitening agents of paper.

Scope of application: The use of whiteboard paper is mainly in high quality printed matter, such as book pages, advertising leaflets, picture albums, magazines, etc. The detection of the scope of application can be carried out by measuring the applicable environment of the paper, the applicable printing variety and the applicable processing technology.

Performance test and test method for whiteboard paper

Surface coating: Whiteboard paper usually needs to be coated to increase its surface hardness, wear resistance and printing quality. The performance test of surface coating can be carried out by measuring the uniformity, hardness, wear resistance, adhesion and other indicators of the coating.

Slidability: The slidability of whiteboard paper refers to its smoothness on a high-speed printing machine and its ability to resist paper jams. The detection of sliding can be carried out by measuring the sliding coefficient of paper, surface smoothness, surface softness and other indicators.

Processability: white board paper needs to have a certain degree of processability to ensure that it can be smoothly carried out in the printing and subsequent processing process. The detection of machinability can be carried out by measuring the surface hardness, surface roughness, suitable processing technology and other indicators of paper.

Anti-aging: the whiteboard paper needs to have good anti-aging to ensure that the printed matter is not easy to fade or yellow in long-term use. The detection of anti-aging can be carried out by measuring the pH of paper, the color difference value after ultraviolet radiation and other indicators.

These performance indicators are the key content of whiteboard paper detection, different use requirements and standards will also affect the detection standards and methods of paper.
