A printing system includes a printing device that receives print jobs. The printing device includes a controller having a raster image processing (RIP) system and a preflight application. The RIP system renders a plurality of pages of a print job. The controller determines that a source page of the plurality of pages includes an error that causes the page to fail to render. The source page is provided to the preflight application. A data file having the source page is opened in the preflight application. The preflight application corrects the error on the source page to generate a corrected page. The corrected page replaces the source page of the plurality of pages of the print job. The corrected page is rendered using the RIP system and printed with the plurality of pages of the print job.

A printing system includes a printing device that receives print jobs. The printing device includes a controller having a raster image processing (RIP) system that includes a RIP manager and at least one renderer. The RIP manager detects that the print engine of the printing device is idle. The RIP system renders various jobs using renderers during the idle time and stores the rendered pages in a storage for the RIP system. Once a storage threshold is reached, the RIP system allocates the renderers to render only complex pages within the print job and stores the rendered complex pages to a secondary storage. If a secondary job is active, then available renderers are allocated to rendering pages of the secondary job. Once printing resumes at the print engine, the RIP manager reallocates the rendering resources back to normal.

The invention provides an overprinted pattern processing method, an industrial printing control method and an industrial printing control system. The overprinted pattern processing method comprises the following steps: decomposing a target overprinted pattern into N printing layers, and defining alternating forward / reverse translation direction attributes for each printing layer; performing grating image processing on each printing layer to generate bitmap image data; y-axis mirror image overturning preprocessing is carried out on bitmap image data of the printing layer with the translation direction attribute being the reverse direction; and embedding registration mark pixel data in the first layer bitmap image data. According to the industrial printing control method, the UV flat plate ink-jet printing equipment is controlled to execute overprinting based on the processing result, printed materials are adsorbed and fixed to the same platform in the whole process, printing of all printing layers is sequentially completed through forward and reverse alternating translation of the platform along the Y axis, and interlayer alignment is completed through registration marks and a visual alignment system. According to the invention, the bitmap image data of the overprinted graph is adaptive to the forward and reverse alternate translation printing mode, and the position deviation introduced by layer-by-layer loading and unloading is eliminated.
