Appl. No.:

10/008818

Inventors:

Michael Piatt - Centerville OH, US
Terry Wozniak - Springfield OH, US

Jennifer Addis - Waterville OH, US

Assignee:

Scitex Digital Printing, Inc.

International Classification:

B41J029/38

US Classification:

347/005000, 347/019000

Abstract:

A system and method are provided for determining ink jet printing system parameters by selecting an appropriate linearizing transformation for application to images to be printed on a printing system for a specific substrate. These transformations can be any transformation capable of being applied in graduated increments and having a corresponding incremental visual influence on the printed output. The present invention allows the user to determine multiple parameters for the printer, including for example, tone scale correction, determination of upper ink limits, amount of under color removal, and allows the user to identify the proper ink level for optimum quality of graphics and/or text printing.

Abstract:

The methods for processing an image from data for imaging on a digital output device include inputting data made of numerous image pixels with values representative of the pixel intensity for imaging to a digital output device, employing a threshold highlight value into the digital output device, and applying data transformation to the data for imaging using the threshold highlight value to form transformed data. The methods end by forming a representation from the transformed data. The representation is a value representative of the pixel intensity greater than or equal to 1.
