Solution Overview
Problem
Existing print systems face inefficiencies due to fixed RIP processes, leading to excessive or mismatched functionality, resulting in increased total process time for printing, especially when handling mixed types of object data across multiple print devices.
Innovation Solution
A print system that includes an analyzing unit to determine required image generating functions for each object, assigns data to appropriate image generating units, synthesizes image data, and prints page images efficiently, allowing for optimized RIP processes and reduced printing time by utilizing a cloud-application print system with multiple image generation server devices.

Engineering Contradiction Analysis
1Adaptability or versatility
If multiple print devices perform RIP processes separately on different object data, then each device can process objects with appropriate image generating functions, but the total process time increases due to repeated printing passes on the same paper sheet
Solution Approach 1:
The patent merges the RIP processes of multiple print devices by having the first print device perform the RIP process on all object data including both first and second object data, then synthesize the processed image data with second image data from the second print device. This combines the processing work into fewer passes, reducing total process time while maintaining appropriate image generating function matching through selective RIP processing.
Solution Approach 2:
The patent segments the image processing into two stages: first, the first print device performs RIP process on first object data to generate first image data; second, the same device processes second object data to generate second image data. These segmented processing results are then synthesized together. This segmentation allows optimal use of each device's image generating functions while avoiding repeated physical printing passes.
2Ease of operation
If a printer controller performs RIP process in a fixed manner according to printer engine function, then the system is simple to operate, but the RIP process becomes excessive or function-mismatched for certain print data
Solution Approach 1:
The patent introduces dynamic selection of RIP processing mode based on the type of object data. The system determines whether to perform full-color RIP or monochrome RIP on the first object data based on whether second object data requiring color processing exists. This dynamic adjustment optimizes processing efficiency while maintaining simple operation through automated decision-making rather than complex fixed configurations.
Solution Approach 2:
The patent changes the RIP processing parameters based on the characteristics of the print data. When the second object data requires color image generating function, the system performs full-color RIP on the first object data; otherwise, it performs monochrome RIP. This parameter change optimizes the matching between RIP process capability and actual print requirements, improving productivity without complicating operation.

AI summary
Provided is a print system which analyzes a print job to generate analysis result information, generating an image for printing by performing an RIP process by using an image generating function required for each object for drawing in each page belonging to the print job based on the analysis result information. In turn, the print system synthesizes an image for printing of each object into a page image based on the analysis result information and prints the page image.
