The color accuracy index of the printing equipment when it is shipped from the factory is aimed at traditional printing. Generally, the four-corner positioning method is only used as the basis for the accuracy of color registration. This technical index cannot describe the linear or nonlinear distortion caused by mechanical inconsistencies in the overall print. It is difficult for non-professional printing staff to see the defects of the flat traditional printed matter in normal application. But for high-end printing industry and special visual raster image printing industry, the color accuracy index of printing equipment is far from enough. Because it requires extremely high color registration accuracy anywhere in the effective printing area to ensure printing quality and yield. This is usually obtained through the purchase of millions of dollars of high-end printing equipment, but after a period of operation, the printing quality and printing yield will still gradually decline. 3D4U Gold Edition adopts the latest high-tech non-linear correction technology of the Meidi Leopard 3D4U printing equipment, which solves all the above-mentioned problems that have long plagued the printing industry, such as trumpets and non-linear registration errors. It can reduce the cumulative color registration error caused by any number of multi-level color printers to the most ideal state. It can also guarantee extremely high color registration accuracy at any position in the effective printing area of ​​the printing equipment. It can even improve the color accuracy of used printing equipment or substandard printing machines to a professional printing level. The digital register technology of 3D4U multi-level color printing machine is the most basic guarantee for the yield of raster image printing. It is also the best choice for the traditional printing industry to improve printing efficiency and print quality.
This technology can also perform linear and non-linear calibration on the tensile parameters of various printing materials commonly used in printing and can give standard reference material parameters. 3D4U nonlinear printing material's tensile parameter correction technology can calibrate the parameters of any conventional printing materials and establish its database. Of course, it is more suitable for parameter calibration of grating printing materials (usually PET APET PETG PP PVC, etc.), and to establish a database. It can be used to quickly and accurately parameterize the selected printed materials in real time.
The soft repair technology of digital image correction can effectively guarantee the absolute accuracy of the output raster image of the 3D4U professional film output synchronous typesetting editing system. The 3D4U Gold Edition can automatically identify the raster material parameters used in the raster image while making the film. According to the original calibration parameters, a raster image center position line array for printing positioning is automatically generated. It is used for printing engineers to hang color separation plates and carry out precision registering during printing. Without any professional raster image printing experience, you can easily complete the printing settings of raster images. The raster image is different from the flat image, it is composed of multiple frames of image, so the alignment of the image and the raster lens is the key factor that directly determines the quality of the final visual effect. If the raster image is typeset with ordinary typesetting software, then The position under the grating lens corresponding to each raster image may be different, which causes the images in the layout to be out of sync. In other words, if a flipped image is lined up with a full version, their flip angles may be different. When viewing the output full-page effect at the same angle, you will see that each raster image has Not the same, because their positions under the grating lens are random, so the scrap rate is extremely high. The 3D4U Gold Edition is based on the above problem using synchronization compensation algorithm to determine the position of each raster image after synchronization calculation, so that the final output layout image can achieve overall synchronization. And effectively prevent "raster image positive jump" error occurs. Raster image synchronous editing and typesetting system combined with non-linear color registration and soft correction technology of digital image correction is an important link to achieve 100% yield of raster image printing.
