    • A multiple raster image processor (RIP) system which enables faster system performance over multiple processors includes a zero RIP feature consisting of a language interpreter sub-RIP that interprets a print instruction file but does not process the graphics rendering steps or the post-language processing operators. The zero RIP discovers page related attributes for individual pages within a multipage job and reports any potential errors or warnings with the file. A thumb RIP consists of a very low resolution RIP that is used specifically for the creation of thumbnail images. A skip RIP interprets selected pages in a way that skips all or most of the processing for that page. Pages to be skipped are scheduled for a different processor, thereby saving processing time and enabling the provision of a multiple processor RIP. A rules based scheduler on an page/face or machine characteristic basis supports a dynamic assignment and assessment algorithm. Scheduling results in optimum use of available resources and requested print constraints (e.g. constrained time window) and optimum use of system bandwidth (e.g. bandwidth control). Archiving and editing capability enables tagged archiving of jobs or parts of jobs in a post RIPed (i.e. raster) format in a special cache located with in the multiRIP system.
    • 多光栅图像处理器(RIP)系统能够在多个处理器上实现更快的系统性能,包括一个零RIP功能,包括一个解释打印指令文件但不处理图形渲染步骤或后处理语言的语言解释器子RIP 运营商。 零RIP会发现多页作业中单个页面的页面相关属性,并报告文件中的任何潜在错误或警告。 拇指RIP由非常低分辨率的RIP组成,专门用于创建缩略图。 跳过RIP以跳过该页面的所有或大部分处理的方式来解释所选页面。 要跳过的页面被调度为不同的处理器,从而节省了处理时间并且能够提供多处理器RIP。 基于页面/面部或机器特征的基于规则的调度器支持动态分配和评估算法。 调度导致最佳使用可用资源和请求的打印限制(例如受限时间窗口)和系统带宽的最佳使用(例如带宽控制)。 存档和编辑功能可以在位于multiRIP系统中的特殊高速缓存中以后RIP(即光栅)格式对作业或作业部分进行标记归档。
