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.

Whiteness: 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. Ang pagtuklas ng gloss ay maaaring gawin sa pamamagitan ng pagsukat ng reflectivity ng ibabaw ng papel.

Kapal at densidad: 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.

Lakas ng loob: Cultural paper needs to be strong enough to withstand the tension and pressure of the printing process. Ang pagsubok ng lakas ay maaaring isagawa sa pamamagitan ng pagsukat ng lakas ng paghatak, pagpunit ng lakas at lakas ng compression ng papel.

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

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, pagsipsip ng langis, printing clarity, color reduction and resistance to printing pollution.

Pangangalaga sa kapaligiran: cultural paper needs to meet environmental standards, does not contain harmful substances, walang polusyon sa kapaligiran. Ang proteksyon sa kapaligiran ay maaaring masuri sa pamamagitan ng pagsukat ng mga volatile organic compounds, mga mabibigat na metal, mga ions ng klorido, floresan brighteners at iba pang mga tagapagpahiwatig.

The above performance indicators are the key contents of cultural paper testing. Iba't ibang mga kinakailangan sa paggamit at pamantayan ay makakaapekto rin sa mga pamantayan sa pagsubok at pamamaraan ng papel.
