Kulturní papír je speciální papír používaný pro tisk knih, časopisy, noviny a další kulturní publikace, as well as making art, obrázková alba, greeting cards and so on. Compared with ordinary paper, cultural paper requires higher smoothness, whiteness, lesk, tloušťka, strength and stability.

Test výkonnosti kulturního papíru

The detection of cultural paper mainly includes the following aspects:

Smoothness: The surface of the cultural paper should be very smooth to ensure clarity and detail of the text and images. The test of smoothness can be carried out by measuring the paper surface smoothness, feather height and plate crown and other indicators.

Bělost: The whiteness of cultural paper needs to meet certain standards to ensure the color restoration and contrast of printed words and images. The detection of whiteness can be carried out by measuring the color and color difference of the light reflected by the paper.

Glossiness: Cultural paper needs a certain glossiness to enhance the visual effect of the print. The detection of gloss can be done by measuring the reflectivity of the paper surface.

Thickness and density: Cultural paper needs to have a certain thickness and density to ensure the stability and durability of the paper. The thickness and density can be measured by measuring the thickness and density of the paper.

Síla: Cultural paper needs to be strong enough to withstand the tension and pressure of the printing process. The test of strength can be carried out by measuring the tensile strength, tearing strength and compression strength of the paper.

Oxidation: Cultural paper needs to have a certain durability, not easy to yellow, aging, decay, atd. The oxidation test can be carried out by measuring the pH value, pH and peroxide index of paper.

Test výkonnosti kulturního papíru

Printing performance: Cultural paper needs to have certain printing performance to ensure the printing quality of printed matter. The detection of printing performance can be carried out by measuring the paper’s water absorption, oil absorption, printing clarity, color reduction and resistance to printing pollution.

Ochrana životního prostředí: cultural paper needs to meet environmental standards, neobsahuje škodlivé látky, žádné znečištění životního prostředí. Environmental protection can be tested by measuring volatile organic compounds, těžké kovy, chloride ions, fluorescent brighteners and other indicators.

The above performance indicators are the key contents of cultural paper testing. Different usage requirements and standards will also affect the testing standards and methods of paper.
