The disadvantages of coated paper mainly include the following aspects:
The silt is easy to stick and fall off after encountering moisture: the surface of coated paper is coated with a layer of white paint, which makes it smooth, high whiteness and good ink-absorbing performance. However, once it encounters a humid environment, the powder on the paper is easy to stick or even fall off, which seriously affects its preservation life and printing effect.
Can not be stored for a long time: because the coated paper is easy to fall off after the moisture, it is not suitable for long-term preservation. This limits its use in applications that require long-term storage, such as important documents and archives.
High requirements for printing equipment and technology: due to the surface characteristics and high requirements of coated paper, professional printing equipment and technology need to be used for printing. This increases the cost and difficulty of printing, and also limits its use in some small printing businesses or individual users.
Relatively high cost: Compared to other types of paper, the production cost of coated paper is higher. This is mainly because its production process includes coating, drying, calendering and other steps, and the requirements for raw materials are also high. Therefore, the price of coated paper is relatively high and is not suitable for mass use or low-cost application scenarios.
In summary, the shortcomings of coated paper are mainly concentrated in the powder is easy to fall off after the tide, can not be kept for a long time, the requirements for printing equipment and technology are high, and the cost is relatively high. These shortcomings limit the application of coated paper in some specific scenarios. However, in applications that require high-quality printing results, such as advanced picture albums, calendars, books, etc., coated paper is still the preferred paper type.
