如何判斷印刷用紙的質(zhì)量

文章作者:華政印務(wù) 發(fā)布時(shí)間:2023-10-12 3
一、外觀質(zhì)量
1、 Appearance quality
外觀質(zhì)量指塵埃、孔洞、針眼、透明點(diǎn)、皺紋、褶子、條痕、網(wǎng)印、毛布痕、斑點(diǎn)、漿疙瘩、云彩花、裂口、色澤不一致等肉眼可以觀察到的缺陷。
Appearance quality refers to defects that can be observed by the naked eye, such as dust, holes, pinholes, transparent spots, wrinkles, folds, streaks, screen prints, woolen marks, spots, bumps, clouds, cracks, and inconsistent colors.
二、力學(xué)性質(zhì)
2、 Mechanical properties
力學(xué)性質(zhì)又稱為機(jī)械性質(zhì)或強(qiáng)度性質(zhì),它又分為靜態(tài)強(qiáng)度和動(dòng)態(tài)強(qiáng)度兩種。
Mechanical properties, also known as mechanical properties or strength properties, are divided into two types: static strength and dynamic strength.
靜態(tài)強(qiáng)度是紙張?jiān)诰徛芰Φ那闆r下所能承受的大力,又稱為終強(qiáng)度。它包括下面幾個(gè)質(zhì)量指標(biāo):抗張強(qiáng)度、耐破度、撕裂度、耐折度、挺度等。
Static strength is the strong force that a paper can withstand under slow force, also known as final strength. It includes the following quality indicators: tensile strength, burst resistance, tearing resistance, folding resistance, stiffness, etc.
動(dòng)態(tài)強(qiáng)度是指紙張能經(jīng)受瞬時(shí)沖擊的強(qiáng)度,它反映了紙張受力后瞬時(shí)擴(kuò)散的動(dòng)態(tài)情況。動(dòng)態(tài)強(qiáng)度主要包括下面幾個(gè)指標(biāo):戳穿強(qiáng)度、環(huán)壓強(qiáng)度、壓縮強(qiáng)度等,這是包裝用紙和紙板重要的質(zhì)量指標(biāo)。-印刷信封
Dynamic strength refers to the strength of a paper that can withstand instantaneous impact, which reflects the dynamic diffusion of the paper after being subjected to force. The dynamic strength mainly includes the following indicators: puncture strength, ring compression strength, compression strength, etc., which are important quality indicators for packaging paper and paperboard- Printing Envelopes

三、基本物理性質(zhì)
3、 Basic physical properties
基本物理性質(zhì)包括紙張的定量、厚度、緊度、平滑度、硬度、松軟度、可壓縮性、吸收性等紙張為普遍的性能。
The basic physical properties of paper include quantity, thickness, tightness, smoothness, hardness, softness, compressibility, absorbency, and other common properties of paper.
四、化學(xué)性質(zhì)
4、 Chemical properties
紙張的化學(xué)性質(zhì)包括紙張的化學(xué)組成、紙張的吸濕性、灰分、施膠度、酸堿性、耐久性。
The chemical properties of paper include its chemical composition, moisture absorption, ash content, sizing degree, acidity and alkalinity, and durability.
五、光學(xué)性質(zhì)
5、 Optical properties
光學(xué)性能指白度(亮度)、色澤度、光澤度、透明度、不透明度等。對(duì)印刷紙張來說,紙張的光學(xué)性能是十分重要的,它直接影響著印刷品的質(zhì)量。
Optical performance refers to whiteness (brightness), chromaticity, glossiness, transparency, opacity, etc. For printing paper, the optical performance of the paper is very important, as it directly affects the quality of the printed product.
