Summary of the invention
Technical problem to be solved by this invention provides a kind of four-color perfecting press, this four-color perfecting press has the paper of maintenance tow sides printing consistency, reduce overprint error, improve the advantage of printing precision, and simple in structure, with low cost, performance is more stable.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of four-color perfecting press, connect and compose by transfer roller by four colour cells, it is characterized in that: each colour cell comprise tangent impression cylinder and blanket cylinder and respectively again with impression cylinder and two tangent plate cylinders of blanket cylinder, described impression cylinder is the rubber impression cylinder.
Adopt technique scheme, impression cylinder adopts the rubber impression cylinder, so just can be so that rubber impression cylinder and blanket cylinder can print the tow sides of paper the tangent of rubber impression cylinder and blanket cylinder simultaneously from the plate cylinder transfer of ink, cause the printing of paper tow sides can not guarantee conforming problem with regard to having overcome original owing to replace printing like this, reduce overprint error, improved printing precision.In addition, because impression cylinder has participated in the printing of the another side of paper, anti-set-off insulator just need not be installed so also again, structure is simpler, has reduced cost, has improved performance.
