Abstract
Official abstract text for this publication.
Systems and methods perform a first monitoring of a printing engine to produce first data; match a disturbance model that empirically describes types of color variation in a print process to the first data; generate a minimum variance control system based on the identified parameters of the disturbance model. The systems/methods infer a benchmark performance level the minimum variance control system achieves using the disturbance model; adjust operating parameters of a controller of the printing engine to match parameters of the minimum variance control system; perform a second monitoring of the printing engine to produce second data; determine a difference value between the benchmark performance level and the second data. If the difference value is above a first value and below a second value, the process is repeated. If the difference value is above the first value and the second value, an indication that the printing engine needs servicing is provided.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: performing a first monitoring of printing results of a printing engine by finding how said printing results vary from targeted print results to produce first data, using a computerized device, said first data comprising variations from said targeted print results; matching a disturbance model that empirically describes types of color variation in a print process to said first data, using said computerized device; generating a minimum…
