AI Technical Summary

Problems solved by technology

Unfortunately, for many cases, the light intensity values ​​vary only slightly with changes in imaging parameter values, and the accuracy of the densitometer may be limited by detecting these small differences
These issues make it very difficult to precisely set specific imaging parameters to optimal values
[0009] Whether utilizing a densitometer or simply visually judging the recording medium, the process is still manual and requires the involvement of trained personnel

Embodiment Construction

[0024] Specific details are introduced in the following description to help those skilled in the art understand more thoroughly. However, to avoid unnecessarily obscuring the present disclosure, well known elements may not have been shown or described in detail. Accordingly, the descriptions and illustrations should be regarded as illustrative, not restrictive.

[0025] figure 1 An imaging and diagnostic system 100 according to an exemplary embodiment of the present invention is schematically shown. The imaging and diagnostic system 100 comprises a recording device 10 for forming an image 19 (ie schematically shown with dashed lines) on a recording medium 17 . The recording device 10 can form different images 19 . In different exemplary embodiments of the invention, different calibration images will be formed to determine optimal set points for particular imaging parameters. Here, for the purpose of describing embodiments of the invention, the image 19 is referred to as a ...

Abstract

A method for adjusting an imaging parameter includes operating a recording head (16) to form a first set of image features (60A) on a media (17). Image features in the first set are formed while the imaging parameter is set to a first predetermined value. The recording head forms a second set of image features (60B) on the media. Features in the second set are formed while the imaging parameter is set to a second predetermined value different from the first predetermined value. Image features of the first set are interleaved with image features of the second set to form an interleaved pattern of image features on the media. Data (47) from the interleaved pattern is generated and analyzed to determine a quantified value representative of banding in the interleaved pattern. The imaging parameters are adjusted based on the quantified value.

Description

technical field [0001] The present invention relates to the technical field of recording apparatuses for forming images on recording media. In particular, the present invention relates to setting imaging parameters of a recording device used to form an image on a recording medium such as a printing plate. Background technique [0002] Large numbers of images are typically printed using contact printing using a high volume printing press. Contact printing machines apply pigments to a surface using various printing elements such as printing plates, printing sleeves, printing cylinders, etc. to form images thereon. The surface may form part of the receiver medium (eg paper) or an intermediate component (eg blanket cylinder of a press) adapted to transfer color from its surface to the receiver medium. In both cases, the pattern of pigments is transferred to the receiver medium, forming an image on the receiver medium. [0003] These printing elements are a form of recording m...
