White card paper is a commonly used printing paper material, usually used to make business cards, hangtags, packaging boxes, cards and other high-grade printed matter.

ביצועים של זיהוי
It needs to have the following main features:

Whiteness: the white card paper needs to have a certain 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 white card paper includes image clarity, color reduction and printing speed. ניתן לבצע את בדיקת איכות ההדפסה על ידי בדיקת אפקט ההדפסה, בהירות קו, הפחתת צבע ואינדיקטורים אחרים של הדפסה.

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

Strength: white card paper needs to have a certain strength to ensure the stability and durability of printed matter. זיהוי חוזק יכול להתבצע על ידי מדידת חוזק המתיחה, flexural strength, compressive strength and other indicators of paper.

Test method for performance of white cardboard

התנגדות ללבוש: white card paper needs to have certain wear resistance to ensure the durability and use effect of printed matter. Wear resistance detection can be carried out by measuring the friction coefficient of the surface of the paper, wear resistance and other indicators.

שמירה על איכות סביבה: white card paper needs to meet environmental protection standards, אינו מכיל חומרים מזיקים, ללא זיהום לסביבה. איתור הגנת הסביבה יכול להתבצע על ידי מדידת התרכובות האורגניות הנדיפות, מתכות כבדות, יוני כלוריד וחומרי הלבנה ניאון של נייר.

היקף היישום: The use of white card paper is mainly in high-grade printed matter, such as business cards, tags, packaging boxes, cards, וכו. זיהוי היקף היישום יכול להתבצע על ידי מדידת הסביבה הרלוונטית של הנייר, the applicable printing variety and the applicable processing technology.

These performance indicators are the key content of white card paper detection, דרישות ותקנים שונים לשימוש ישפיעו גם על תקני הגילוי ושיטות הנייר. בנוסף, because white card paper is usually used in the production of high-grade printed matter, its appearance quality is also a very important index, need to carry out appearance detection, such as surface flatness, surface gloss, surface smoothness, surface defect and other indicators.
