Embodiment Construction

[0081] The present invention will be further described below in conjunction with the accompanying drawings and examples, but they cannot be used to limit the scope of the present invention.

[0082] The quality of inkjet printing plate making is closely related to the ink used, substrate, and printing control process parameters. This embodiment describes the microscopic quality inspection process of the printing plate imaged by the 1800dpi printout.

[0083] The detection system used consists of two parts, hardware and software. The hardware includes microscopic magnification optical system, CCD color imaging device and computer, etc.; the software is a calculation tool for image acquisition and various microscopic quality indicators. Such as figure 2 As shown, the test system includes a microscope 1, a CCD imaging device 2, a ring light source 3, a computer 4, a display 5, a power supply 6, an xy mobile storage platform 7, a test sample 8, and the like.

Abstract

The invention relates to a microscopic quality detection method for printing, platemaking and imaging, and belongs to the technical field of green printing. The method comprises the following steps: firstly, fabricating a digital original manuscript containing a printing plate imaging microscopic quality detection pattern, and printing and imaging as a detection drawing board; adopting an optical microscope amplifying and colored CCD imaging system, wherein a CCD imaging device is used for adjusting the used imaging white light source into white balance, and calibrating object surface scale resolution of a digital image formed by the CCD under a microscopic imaging condition; calibrating printing plate light reflectivity of CCD imaging by virtue of a standard color plate under the same microscopic imaging condition; imaging a unit pattern of a detecting drawing board under the same microscopic imaging condition to form an RGB digital image; and obtaining a light reflectivity grey image of the unit pattern of the drawing board from the light reflectivity calibration relationship; and obtaining a quality attribute index value of a pattern print by a digital image processing technology. The detection method can be applied to microscopic quality detection and quality control for printing, platemaking and imaging.

Description

technical field [0001] The invention relates to a microscopic quality detection method for inkjet printing plate-making imaging, which belongs to the technical field of green printing. Background technique [0002] Printing technology is developing towards digitalization and green environmental protection. Various imaging systems, including inkjet and electrostatic, have been applied and developed rapidly in the production of final printed matter. At the same time, this new technology is constantly changing the traditional printing plate making process. At present, not only the CTP technology of laser scanning and imaging has abandoned film and plate printing, but also direct plate-making technologies such as inkjet imaging have emerged, which further omits the liquid development process of laser CTP plate-making, greatly improving the green and environmental protection of plate-making technology. [0003] The plate making technology of inkjet printing process, compared wi...
