How To Choose The Rubber Head Before Printing

Generally, the printing effect of the sharp rubber head is more beautiful, but too sharp for too large pattern printing will deform, so the tendency of the rubber head will reduce the distortion of printing. At the same time, if the speed is controlled, it will make the printing effect more perfect.

Move offset head hardness performance rubber head ability to resist compression deformation, in printing, soft rubber head can obtain larger deformation, suitable for not very regular printing, had better choose soft rubber head, rubber head and printing products, and the hard adhesive head deformation is smaller, printing network expansion is small, used in plane printing or color dot pattern printing, such as more fine printing pattern can also choose more hard glue head, printed text and pattern is not deformation.

The service life of the printing rubber head and the utilization rate of products, ink, steel plate, depth are closely related. In the process of repeated printing on the wear of the rubber head, with the elastic deformation, there is a crack, the general printing pattern is not very good, it should be changed.

The relationship between rubber head and ink, the printing offset head is often printed in the process of transferring ink and solvent. In the printing process, it is recommended not to print less good ink and solvent, and it is the same for printing steel plate. Good ink for the rubber head and ink, printing effect is good.

The shape of the rubber head, the volume of the printing rubber head should be compared to the printed pattern, just right, the rubber head is too large and small pattern will cause waste. Pressure on the machine also increases, different printing products require different glue heads, If the installation position is found in the printing process is too partial, the force is too large and too small, the central position of the rubber head of the printing machine should be adjusted appropriately.
