Color Management Architecture and Printing Process Integration (below)

Open Printing Process and Color Management Architecture

DTP and CTP lead to the introduction of an open sound brush environment and numerous color management systems/software hardware, and an integrated approach to color separation input and proofing The processes are all related to the color management process.

First, the color management printing environment:

To do color management requires the following instruments and components:

Color measuring instrument

2. Color management software

3. Integration of existing tools and existing production processes: Including existing computer operating systems, application software support, and output environment cooperation are the most important keys in the color management process.

Second, color input color management:

The RGB signals scanned by the scanner are converted into CMYK files for subsequent printing. We define it as the color management flow for color separation input.

So you must:

1. Create a profile for the input device

2. Set the input image original according to the profile established by the studio

3. Determine if the image file format is associated with Profile

4. Confirm the profile of the output device

5. Color correspondence and conversion of image data

6. Typesetting group page and output

Third, the separation of input considerations:

1. Scanner settings

2. Ideal for perfect manuscripts

3. Need for color correction/color gamut correspondence

4. Difficulties in sRGB, resulting in difficulties in use

5. How to integrate with RIP/Sever

6. How to evaluate the efficiency of the system

7. It can avoid the dependency of ink and other output characteristics

8. Still have a good output profile

Fourth, the color output of proofing

The color management required for proofing output needs:

1. Create a target profile

2. Establish a Profile Proofing Device

3. Absolute color conversion mode

Fifth, the proof output considerations:

1. The color gamut of the proofing equipment should be wide enough

2. The stability of the proofing equipment should be high enough

3. Non-four-color output characteristics

4. Differences in Black Replacement

5. Acceptability of FM network

Vision of the future

1. The theory of color management is feasible

2. Color management equipment continues to improve

3. Quality relative to expectations

4. Workflow needs to be adjusted and optimized

5. The education and training of personnel is the focus

6. Increasing productivity and reducing costs without affecting quality are goals.
