Prepress can solve the problem of inaccurate printing technology

The accuracy index of printing equipment at the time of leaving the factory is aimed at the traditional printing. Generally, only the four-corner positioning method is used as the basis for the accuracy of color registration. This specification does not describe the linear or nonlinear distortion caused by mechanical inconsistencies in the overall print. For the normal flat prints of normal applications, it is difficult for non-professional printers to see the defects. However, for the high-end printing industry and special visual raster image printers, the accuracy index of printing equipment registration is not enough. Because it requires extremely high color registration accuracy at any position within the effective printing area to ensure print quality and yield. This is usually achieved by using multi-million dollar high-end printing equipment, but after a certain period of time, the print quality and printed product yield will still gradually decline. The 3D4U Gold Edition adopts the latest printing equipment of the American Di Leopard 3D4U to correct high-frequency non-linearities, solving all the above-mentioned issues that have long plagued the printing industry and the problem of nonlinear trapping errors. It can reduce the cumulative trapping error caused by any combination of multi-level color presses to the optimal state. It can guarantee that the high trapping accuracy can be obtained 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 presses to a professional printing level. The digital color registration technology of the 3D4U multi-level color printing press is the most basic guarantee for the raster image printing yield. It is also the best choice for the traditional printing industry to improve the printing efficiency and printing quality.

This technique can also linearly and nonlinearly calibrate the stretching parameters of various printing materials commonly used in printing and give standard reference material parameters. The stretch parameter correction technology of 3D4U non-linear printing material can calibrate the parameters of any conventional printing materials and establish its database. Of course, it is more suitable for parameter calibration of lenticular printing materials (commonly used PET APET PETG PP PVC, etc.) and establishment of a database. It can be used to quickly and accurately parameterize selected printed materials in real time.

The digital image correction soft repair technology 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 automatically recognizes the grating material parameters selected for the raster image while making the film. And according to the original calibration parameters, the raster image center position positioning line array for printing positioning is automatically generated. For printing engineers to hang color printing and precise nesting in printing. No need for any professional raster image printing experience can easily complete the print setup and adjustment of raster images. The raster image is different from the planar image. It is composed of multi-frame images. Therefore, the alignment between the image and the lenticular lens is a key factor that directly determines the quality of the final visual effect. If raster images are typeset with ordinary typesetting software, then Each raster image may have different positions under the lenticular lens, which results in the images in the layout being out of sync. In other words, if you flip a converted image into a full page, then their flip angles may be different. When you view the full effect after output in the same angle, you will see every raster image. Not the same, because their position under the lenticular lens is random, the rejection rate is extremely high. The 3D4U Gold Edition uses the synchronous compensation algorithm to solve the above problems. After each raster image is calculated synchronously, the position is determined, so that the final output typeset image can achieve overall synchronization. Effectively prevent errors in the "positive transition of raster images" from occurring. Raster image synchronization editing and typesetting system with non-linear color correction and digital image correction soft repair technology is an important part of achieving raster image printing to 100% yield.
