Embodiment Construction

[0037] The invention provides a method for realizing online printing of changing content on a rotary printing machine. The specific method is to set a multi-color inkjet digital printing unit seamlessly connected with the rotary printing machine; to set a central control unit, and the central The control unit includes a rotary encoding control subunit, a color code information control subunit, a variable content printing position and printing content control subunit, a main control subunit and a data storage subunit; the variable content printing position and printing content control subunit is used Before starting printing, the printing position information of the changing content to be printed on the continuous substrate, and the text or / and pattern information of the changing content are pre-input into the central control unit and stored in the data storage subunit. When the change content printing position and printing content control subunit converts the printing position ...

Abstract

The invention relates to a method for realizing changing content on-line print on a rotary press and a mixing digital printing system. The method comprises the following steps: providing a multicolor ink-jet digital printing unit on the rotary press; providing a central control unit to enable a continuous printing stock to pass through an ink-jet region of an ink-jet head of the multicolor ink-jet digital printing unit with the running speed equal to that of the rotary press; carrying out ink jet by the ink-jet head after the multicolor ink-jet digital printing unit receives a color patch information control electrical signal; controlling a predetermining position of the ink-jet head on the continuous printing stock according to a printing position control electrical signal and a printing content information control electrical signal; jetting predetermining characters or/and patterns; and jetting ink by the ink-jet head with the ink-jet speed adapted to the running speed of the continuous printing stock according to the rotary code control electrical signal. The invention can not only carry out large-scale printing, but also realize the changing content on-line printing on the rotary press on the basis of the synchronous on-line print of changeable contents.

Description

technical field [0001] The invention relates to a method for realizing online printing of changing content on a rotary printing machine and a hybrid digital printing system. Background technique [0002] Various traditional printing methods include: offset printing, flexo printing, letterpress printing, gravure printing, line gravure printing, silk screen printing. They each have their own advantages. For example, offset printing is characterized by its advantages in printing accurate halftones, uniform gradients, and high definition; while flexo printing is good at solid printing, metallic ink printing, and local glazing; Metal ink printing, security printing, and on-site printing have advantages, and have a thicker ink layer thickness; line gravure printing has unique features in line printing and security printing; screen printing has advantages in ink layer thickness, metal ink and special printing. Specialties in printing effects. In the past, in order to make the pri...
