AN INKJET PRINTING APPARATUS AND MANUFACTURING METHOD FOR ABSORBENT SUBSTRATE |
摘要 |
An inkjet printing apparatus for printing an image on an absorbent substrate includes a print head unit and a dust removal device. The absorbent substrate includes a print side and an opposite side and is conveyed between the print-head unit and the dust removal device. The print head unit defines a print zone on the print side. The dust removal device includes a pumping chamber formed of a pre-pumping sub-chamber, a print zone sub-chamber, and a post-pumping sub-chamber, said chambers being positioned at the opposite side. The pre-pumping sub-chamber is positioned substantially upstream from the print zone. The print zone sub-chamber is positioned substantially at the print zone. The post-pumping sub-chamber is positioned downstream from the print zone. A second pressure in the print zone sub-chamber is higher than a first pressure in the pre-pumping sub-chamber and a third pressure in the post-pumping sub-chamber so as to create a suction impact to dust particles generated by the conveyed absorbent substrate. |
