The appearance quality of paper refers to the quality of paper that can be discriminated only by human senses without using equipment. It can be divided into the appearance quality of the paper itself and the appearance quality of the piece of paper formed by a sheet of paper or a long strip of paper.
No matter what kind of appearance quality affects the use of paper to varying degrees. The poor appearance quality will not only reduce the paper's use value and the printed product yield, but also cause the paper to be scrap when serious. In addition, some serious paper defects in paper, such as hard paper blocks, will also squash the plates and rollers during printing, causing damage to printing equipment. The appearance quality and physical properties of paper are also closely related. For example, papers with apparent seersuckers may also suffer from smoothness and opacity.
★ The appearance quality inspection of paper should achieve the following three purposes:
★ Check the quality of the paper. Mainly include: whether the shape of the paper is good, the size is qualified, the packaging quality and the degree of damage.
★ Master the basic paper quality of paper. Including color, uniform level, flexible tensile, smoothness and cleanliness.
★ Check out the approximate miss rate of lithographic paper (percentage of paper with obvious paper disease).
