- H04N 1/6072: {adapting to different types of images, e.g. characters, graphs, black and white image portions}
- H04N 1/6019: {using look-up tables (H04N1/6025 takes precedence)}
- H04N 1/6058: {Reduction of colour to a range of reproducible colours, e.g. to ink- reproducible colour gamut}
- H04N: PICTORIAL COMMUNICATION, e.g. TELEVISION

## Abstract

Automated selection of a best gamut mapping strategy for a given element of the print job adapts the color management process to manage all important elements and quality criteria for all content elements of a print product to produce an optimal print product. Criteria which have a lower priority for a particular content are compromised. Accordingly, optimal image quality is achieved for every content element and printer color management settings are simplified.

## Claims

### Claim 1

A computer implemented method for image classification for color management in printing, comprising:
creating ICC color profiles or similar, containing color lookup tables (CLUTs) that describe gamut mapping of input colors to output colors, wherein said CLUTs are created for different applications;
using a convolutional neural network (CNN) that is trained to perform image classification and object detection to analyze and tag images to be printed and/or to mask part of said images to be printed with a classification category;
a color management module (CMM) using said classification tags or masks to select a best suited color lookup table automatically; and
said CMM applying said table during color conversion to a color space of a printing device.

### Claim 2 (depends on 1)

The method of claim 1, wherein said CLUTs are created for any of a table for best reproduction of photographic images, for office applications, best numerical color match, technical equipment, people, and nature.
