一、观察外观 首先，观察卡纸的外观是最基本的辨别方法。好的卡纸表面光滑、细腻，颜色鲜艳且均匀，无明显的瑕疵和色差。而质量差的卡纸表面往往会有粗糙的颗粒感，颜色黯淡，有斑点、污迹等问题。 二、摸触感 摸触感也是一种重要的辨别方法。好的卡纸手感细腻、柔软，不易撕破或产生静电。而质量差的卡纸则手感粗糙、硬脆，容易撕破或带静电。 三、观察纸质 除了外观和手感外，我们还可以通过观察卡纸的纸质来辨别其质量。好的卡纸纸质紧密、均匀，纤维细腻，不易变形或起皱。而质量差的卡纸则纸质松散、不均匀，纤维粗糙，容易变形或起皱。 四、检查墨水渗透情况 墨水渗透情况也是判断卡纸质量的重要指标之一。好的卡纸墨水不易渗透，印刷效果清晰、鲜艳，且不易褪色。而质量差的卡纸则墨水容易渗透，印刷效果模糊、暗淡，甚至出现晕染现象。 五、参考品牌和价格 在购买卡纸时，我们还可以参考品牌和价格等因素来判断其质量。一般来说，知名品牌的卡纸质量相对较为稳定可靠，价格也相对较高。而价格过低的卡纸往往质量较差，可能存在掺杂、使用次品等问题。 How to identify poor quality cardstock? Cardstock is a common type of paper widely used in various printing and production fields. However, due to the numerous brands and types of cardstock available in the market with varying quality, it is essential to learn how to distinguish between good and poor-quality cardstock. Below, we will introduce some methods to identify cardstock quality. I. Observing the appearance Firstly, observing the appearance of the cardstock is the most basic way to distinguish its quality. Good cardstock has a smooth and delicate surface, with bright and even colors, and no obvious flaws or color differences. In contrast, poor-quality cardstock often has a rough grainy texture, dull colors, and issues such as spots or stains. II. Touching the feel Touching is also an important way to distinguish cardstock quality. Good cardstock has a soft and delicate texture that is not easy to tear or produce static electricity. In contrast, poor-quality cardstock tends to be rough and brittle, prone to tearing or static electricity. III. Observing the paper quality In addition to appearance and touch, we can also observe the paper quality of the cardstock to determine its quality. Good cardstock has a dense and uniform texture with fine fibers that are not prone to deformation or wrinkling. In contrast, poor-quality cardstock tends to have loose and uneven texture with rough fibers that are prone to deformation or wrinkling. IV. Checking ink penetration Ink penetration is also an important indicator for judging the quality of cardstock. Good cardstock has a low ink penetration rate, resulting in clear and bright printing effects that are not prone to fading. In contrast, poor-quality cardstock tends to have ink easily penetrate, resulting in blurry and dark printing effects, or even bleeding.

V. Considering brand and price

When purchasing cardstock, we can also consider factors such as brand and price to judge its quality. Generally speaking, well-known brands of cardstock tend to have relatively stable and reliable quality, with higher prices. In contrast, cardstock with extremely low prices often has poor quality, possibly due to doping or using inferior products.
