The detection of cultural paper mainly includes the following aspects:

Levigatezza: The surface of the cultural paper should be very smooth to ensure clarity and detail of the text and images. Il test di levigatezza può essere effettuato misurando la levigatezza della superficie della carta, altezza della piuma e corona della piastra e altri indicatori.

Bianchezza: 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.

Spessore e densità: 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.

Forza: Cultural paper needs to be strong enough to withstand the tension and pressure of the printing process. La prova di resistenza può essere effettuata misurando la resistenza alla trazione, tearing strength and compression strength of the paper.

Oxidation: Cultural paper needs to have a certain durability, not easy to yellow, invecchiamento, decay, eccetera. 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, oil absorption, printing clarity, color reduction and resistance to printing pollution.

Protezione ambientale: cultural paper needs to meet environmental standards, non contiene sostanze nocive, nessun inquinamento per l'ambiente. La protezione dell’ambiente può essere testata misurando i composti organici volatili, metalli pesanti, ioni cloruro, sbiancanti fluorescenti e altri indicatori.

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.
