Problems solved by technology

In addition, during the drying process after printing, the drying temperature needs to be strictly controlled. If the drying temperature is too low, the drying time will be prolonged and the printing efficiency will be reduced; while the drying temperature is too high, the paper will be deformed, which will affect the printing quality.

Embodiment 1

[0027] (1) Dust removal: Use the dust removal brush roller to remove dust from the paper, and the paper after dust removal is curled into rolls by the winder;

[0028] (2) Unwinding: install the paper roll on the unwinding machine and lead out the paper;

[0029] (3) Printing: the paper passes through the printing machine, and the printing machine prints water-based ink on the paper;

[0030] (4) Drying: The printed paper passes through the first-level air-drying room and the second-level air-drying room in turn to completely cure the water-based ink;

[0031] (5) Rolling: The dried paper is rolled into a roll by the winding machine, which completes the water-based printing of paper printed matter.

[0032] The brush head of the dedusting brush roller is in interference contact with the surface of the paper, and the interference height is controlled at 0.5mm; the speed of the paper passing through the dedusting brush roller is controlled at 5m / min; the water-based ink uses wa...

Abstract

The invention discloses a water printing process for paper printed matters, and relates to the technical field of printing. The process comprises the steps of (1) dust removal, (2) unwinding, (3) printing, (4) drying and (5) winding. Through dust removal of papers before printing, the influence on the printing quality by attachment of dust on the papers is prevented; through use of water ink, theprinting environment is improved, and the environmental pollution problem caused by use of solvent ink is prevented; and meanwhile, through arrangement of a two-grade airing chamber, the drying quality is guaranteed when the ink drying efficiency is improved, and deformation of the papers caused by higher drying temperature is prevented.

Description

Technical field: [0001] The invention relates to the technical field of printing, in particular to a water-based printing process for paper printed matter. Background technique: [0002] A printing press is a machine for printing text and images. It is generally composed of plate loading, ink application, embossing, material feeding, material receiving platform and other mechanisms. The working principle is to first make the printing plate of the text and image to be printed, install it on the printing machine, and then apply the ink to the place with the text and image on the printing plate manually or by the printing machine, and then directly or indirectly transfer it to the paper. or other substrates to reproduce the same print as the printing plate. [0003] At present, most of the substrates used in printed matter are paper, but during the process of processing and storage, dust may adhere to the surface of the paper. If the dust is not removed, white spots will appe...
