Carbonless base paper is a special printing paper, usually used to make office supplies such as carbon paper or carbon ribbon. It has the feature of rewriting without toner or ribbon, which can greatly improve work efficiency and save costs.
Detection performance
Carbon-free base paper needs to have the following main properties:
Degree of carbonization: The degree of carbonization of carbon-free base paper is one of its important performance indicators, which determines the copying effect and quality of paper when copying. The degree of carbonization can be detected by measuring the carbonization rate and carbon blackness of the paper surface.
Printing quality: The printing quality of carbonless base paper includes indicators such as image clarity, color reproduction and printing speed. The detection of printing quality can be carried out by checking the printing effect, line clarity, color reproduction and other indicators of printed matter.
Paper strength: Carbonless base paper needs to have a certain strength to ensure its stability and durability. The detection of strength can be carried out by measuring the tensile strength, tear strength, folding endurance and other indicators of paper.
Paper thickness and uniformity: The thickness and uniformity of carbonless base paper will directly affect the printing effect and quality of printed matter. The detection of thickness and uniformity can be carried out by measuring indicators such as paper thickness, basis weight and thickness difference.
Durability: Carbonless base paper needs to have a certain degree of durability to ensure that the copied text and patterns are not easy to fall off and blur. The durability test can be carried out by measuring the friction resistance and water resistance of the paper.
Environmental protection: Carbon-free base paper needs to meet environmental protection standards, contain no harmful substances, and have no pollution to the environment. The detection of environmental protection can be carried out by measuring indicators such as volatile organic compounds, heavy metals, chloride ions and fluorescent whitening agents of paper.
Scope of application: The scope of use of carbonless base paper is mainly in the production of office supplies such as carbon paper or carbon ribbon. The detection of the scope of application can be carried out by measuring the applicable environment of the paper, the applicable copying model and the applicable copying paper and other indicators.
The above performance indicators are the key , and different use requirements and standards will also affect the detection standards and methods of paper.
