Description
Technical Field
The invention relates to the technical field of printing, in particular to a method for repairing decolored powder and scratches on the surface of a printed matter.
Background
In common telephone, the quality of a printed matter is printed in three parts and plate making in seven parts, gravure printing is used as one of the printing processes, and the advantages of thick ink layer, bright color, high saturation, high printing plate printing resistance, stable quality of the printed matter, high printing speed and the like of the printed matter occupy extremely important positions in the fields of printing packaging and graphic publishing; in terms of application, gravure printing is mainly used for fine publications such as magazines and catalogues, package printing and printing of securities such as banknotes and stamps, and is also applied to special fields such as decorative materials.
In the gravure process, people often see that the color of certain printed matter layout is lighter, even the fading and the powder falling are serious, the quality of the product is directly influenced, and the influencing factors mainly have two aspects:
firstly, the image and text of a printing plate layout are worn out due to the abrasion of the printing plate, the opening of an inking hole is reduced, the depth is shallower, the area of an ink transfer unit is reduced, the total ink transfer amount is correspondingly reduced, the ink color is diluted, and the defects are caused; the main factors of plate wear include: the defects caused by the reasons such as friction on the surface of a printing plate, excessive pressure of a doctor blade, linear speed of a printing plate roller and an embossing roller, abrasion of paper and ink on the printing plate and the like are obvious, can be quickly found in the normal production process, and can be correspondingly adjusted in time by searching the corresponding reasons, and the corresponding solutions generally reduce the pressure of the printing plate and the pressure of the doctor blade, eliminate large particles in the ink and control the drying speed of the ink, so that the defects of batch products are basically avoided, and large economic loss is avoided.
The second is more involved, however, and more is caused by chemical factors. The abrasion resistance is reduced or the drying is not thorough due to improper control of the viscosity of the ink in the printing process, and the adhesive force of the ink on the surface of a printed matter is reduced due to improper control of some external environmental factors. The consequences caused by the factors cannot be timely displayed in the production process, and the defect exposure has the characteristic of delay, so that the defects cannot be timely adjusted in the production process, only the production of the product is finished, and the defects are only displayed in the subsequent processing process, so that the large economic loss is caused. For example, in 2013, some known packaging material company provides cigarette cartons for cigarette enterprises, serious powder dropping occurs in the process of packaging cigarettes, and the cigarette cartons of the batch have a value of more than 200 ten thousand RMB, so that serious economic loss is caused for the packaging material company, and the loss is compensated by various restoration means within a specified time, but no good effect is achieved.
