The relationship between printing speed and quality of hardcover books
The offset printing in the printing factory adopts the indirect printing method. The reason why the image and text on the plate can be transferred to the paper depends on the cylinder pressure. Therefore, when the speed of the printing machine increases, the pressure of the drum will increase accordingly. Today, a small edition of Shenzhen printing factory talks about the relationship between the press speed pressure and quality;
No printing errors are allowed in hardcover printing. The increase of printing speed means that the contact time between printing plate and blanket, between blanket and the paper of the substrate is correspondingly reduced. With the decrease of this time, the degree of incomplete contact between printing surfaces increases, which generally results in quality accidents such as plate dropping and color difference.
The press appropriateness of the printing press in the printing factory is often manifested by the printing quality of the printed matter. The pressure should be applied within a reasonable range on the premise of whether the hardcover printing sheet has a firm dot, clear graphics and text, bright colors and co scheduling of density and density.
The reasonable pressure should be able to use the minimum pressure evenly under the condition of certain printing surface deformation on the basis of strong enough imprinting to obtain a satisfactory ink volume and transfer the printing pressure properly. A certain speed corresponds to a reasonable pressure, what the printing factory has done is to effectively control these two variables to get high quality prints.
