An Aluminum offset printing plate is a necessary product in offset printing. The use of aluminum plates has more advantages than that of other materials. They are frequently used in printing products like business cards, catalogs, and brochures.
Definition
Aluminum offset printing plates are a necessary product in offset printing. This form of printing is based on ancient techniques. A light or laser line illuminates the plate, thereby applying ink to the image area. About one-third of the world's prints use this printing technique. They are used in printing products like business cards, catalogs, and brochures.
Apparent Quality of the Aluminum Plate Base
The apparent quality of the aluminum plate base, which is the most difficult aspect of CTP plate production to control, has a significant impact on both production and product quality. Therefore, the apparent quality of the aluminum plate base is a requirement in order to guarantee the quality of CTP printing plates.
The rell packaging's appearance quality and the aluminum plate base's apparent quality make up the two components of the apparent quality of the aluminum plate base. The former is frequently ignored as well.
The Effect of Aluminum Plate Surface Quality Based on CTP Printing Plate
Aluminum Substrate Offset Printing PS Plate
The imported aluminum plate base has stable apparent quality, and the defect rate is lower than 0.5%; while the domestic CTP plate uses an aluminum plate base with many surface defects and poor quality stability. So the technology and management levels further improve.
Faced with this situation, CTP plate manufacturers should put forward specific requirements for the quality of aluminum plate bases according to their own equipment capabilities, electrolytic corrosion capabilities, and other process conditions;
Quality Requirements
In general, the aluminum plate base should have good apparent quality, uniform quality, no stains, bumps, scratches, creases, edge oxidation, non-metallic indentation and sticking, etc. No rolling or rolling lines visible to the eye are not allowed. and other defects that affect printing. On the premise of ensuring product quality, the surface oil content should be minimized.
Advantages of Aluminum Offset Printing Plates
(1) Higher printing quality;
Aluminum offset printing plates don't use film, preventing a number of film-related flaws and enhancing the stability and dependability of plate production. Furthermore, CTP aluminum offset printing technology makes use of more precise positioning technology, which significantly lowers the errors brought on by manual splicing.
(2) Shorter printing cycle；
Light and heat energy are used to directly image the aluminum offset plate, obviating the need for printing, assembly, printing, and other processes. This speeds up plate production and reduces debugging time, greatly increasing productivity.
(3) More environmentally friendly.
The use of no-wash thermal plates and chemical-free show drugs in CTP aluminum offset printing technology prevents the creation of toxic waste water and other harmful substances, thereby protecting the environment and producing truly green plates.
