The color precision index of the printing equipment at the factory is aimed at the traditional printing. Generally, the four-corner positioning method is only used as the basis for accurate color registration. This technical indicator does not describe linear or nonlinear distortion caused by mechanical inconsistencies in the overall print. For flat traditional prints for normal applications, it is difficult for non-professional printers to see their flaws. However, for the high-end printing industry and the special visual raster image printing industry, the printing equipment color accuracy index is not enough. Because it requires extremely high color registration accuracy at any location within the effective printing area to ensure print quality and yield. This is usually achieved by purchasing millions of dollars of high-end printing equipment, but after a period of operation, print quality and print yield will continue to decline. The 3D4U Gold Edition uses the latest printing equipment nonlinear correction technology, which solves all the problems of the trumpet and nonlinear color registration errors that have been plagued by the printing industry for a long time. It reduces the cumulative color registration error caused by any number of combined multi-level color presses to the optimal state. It also guarantees extremely high color registration accuracy at any position within the effective printing area of the printing equipment. It is even possible to increase the color registration accuracy of used printing equipment or substandard printing machines to a professional printing level. The digital color registration technology of 3D4U multi-level color printing machine is the most basic guarantee for the raster image printing yield. It is also the best choice for the traditional printing industry to improve printing efficiency and print quality.
The technology also provides linear and non-linear calibration of the tensile parameters of various printed materials commonly used in printing and gives standard reference material parameters. The stretch parameter correction technique of 3D4U nonlinear printed materials allows parameter calibration of any conventional printed material and builds its database. Of course, it is also more suitable for parameter calibration of lenticular printing materials (commonly used PET APET PETG PP PVC, etc.) and to establish a database. It can be used to quickly and accurately parameterize selected printed materials in real time.
The soft repair technology of digital image rectification can effectively guarantee the absolute precision of the output raster image of the 3D4U professional film output synchronous layout editing system. The 3D4U Gold Edition automatically recognizes the grating material parameters selected for the raster image while making the film. And the raster image center position positioning line array for printing positioning is automatically generated according to the original calibration parameters. It is used by printing engineers to hang color separation plates and perform precise positioning in printing. The setup and adjustment of the raster image can be easily performed without any professional raster image printing experience. The raster image is different from the planar image, which is synthesized by multi-frame images, so the alignment between the image and the grating lens is the key factor that directly determines the final visual effect. If the raster image is typeset using ordinary typesetting software, then The position of the raster 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 filled with a full-page, then their flip angles may be different. When viewing the output full-page effect at the same angle, you will see each raster image. Not the same, because their position under the grating lens is random, so the scrap rate is extremely high. The 3D4U Gold Edition uses the algorithm of synchronous compensation for the above problems to calculate the position after each raster image is synchronously calculated, so that the final output layout image can achieve overall synchronization. And effectively eliminate the "grating image front jump" error occurs. The raster image synchronization editing typesetting system combined with the nonlinear color registration and digital image rectification soft repair technology is an important part of achieving raster image printing to achieve 100% yield.
