Print Image Processing Device for Inkjet Cost Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing print control devices for ink jet printers require repetitive trial and error to achieve desired print costs and lack information for comparative evaluation of print options, making it inefficient to select optimal print conditions.
Innovation Solution
A print image processing device with an input unit for entering print conditions, a conversion unit to convert image information into print images, and a display unit that shows selection candidates based on input conditions, including print cost, ink attributes, printing apparatus attributes, and tolerable image quality, allowing for easy selection without repetitive editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If print control devices calculate print cost based on edited content, then print cost calculation accuracy is improved, but operational efficiency deteriorates due to repetitive trial and error editing
Solution Approach 1:
The system performs preliminary actions by automatically generating multiple print image candidates with different editing options before the user makes a selection. The conversion unit creates various versions of the print image based on different layout, scaling, or content arrangement options, allowing the user to review and select the most suitable option without having to manually edit each version.
Solution Approach 2:
The system creates multiple copies of the print image with different editing parameters applied to each copy. Instead of requiring the user to manually edit the original image repeatedly, the conversion unit generates multiple candidate versions that can be reviewed simultaneously, reducing the need for repetitive manual editing while maintaining accurate cost calculation for each version.
2Device complexity
If print control devices display only final print cost, then information simplicity is improved, but decision-making capability deteriorates due to lack of comparative evaluation information
Solution Approach 1:
The system segments the print image information into multiple discrete candidate versions, each with its own cost calculation. Instead of presenting a single aggregated cost figure, the display unit divides the information into separate, comparable units (different print image candidates), allowing users to evaluate each option independently while maintaining overall information simplicity through structured presentation.
Solution Approach 2:
The system adds a new dimension to the information presentation by displaying multiple print image candidates side-by-side with their respective cost calculations. This transforms the information from a single-dimensional cost figure into a multi-dimensional comparison matrix that includes visual previews, cost data, and editing parameters, enhancing decision-making capability without overwhelming the user.

AI summary
A print image processing device includes an input unit to which print conditions are input, a conversion unit (a printer driver) which converts image information into a print image, and a display unit which displays selection candidates (sample images) of the print image which is formed based on the input print conditions in a selectable manner.
