Problems solved by technology

[0019] However, with the above-mentioned technology, due to the data reading and analysis errors in the measurement of the colorimetric spectrometer, the IT8 color test sheet printed by the printing equipment will also have certain deviations. The result of printing digital proofs is often difficult to ideally simulate the printing effect of current printing equipment, and cannot meet high-standard technical requirements

Embodiment 1

[0031] The color management method in digital proofing includes the following steps:

[0032] 1. According to the requirements and printing standards, determine all the relevant data of the printing equipment, and print out the IT8 color test table.

[0033] 2. Use the digital output device to print the IT8 color test table without color management.

[0034] 3. Measure the two IT8 color test tables with a color spectrometer to obtain the ICC Profile of the digital output device and the ICC Profile of the printing device.

[0035] 4. Carry out color adjustment on the color management platform. According to the difference between the ICC Profile of the digital output device and the ICC Profile of the printing device for each color block of the IT8 color test table, the difference between the ICC Profile of the digital output device and the ICC Profile of the printing device is adjusted, and the corrected ICC for the current printing device in the current state is obtained.

Embodiment 2

[0040] According to the color management method in the digital proofing of Example 1, but the color management platform refers to "Best color" or "O.R.I.S.Color Tuner"; the densitometer is an X-Rite densitometer.

Embodiment 3

[0042] According to the color management method in the digital proofing of embodiment 2, but the color test table is not limited to the IT8 color test table.

Abstract

The invention discloses a color management method for the digital printing which comprises, printing IT8 color test table using the digital output equipment and printing equipment, performing measurement using color measuring spectrometer respectively, obtaining the ICC profile of the printing equipment and the ICC profile of the digital output equipment for color adjustment, acquiring the revised ICC profile, proceeding second revision, obtaining the digital sample manuscript of the digital output equipment.

Description

Technical field [0001] The invention relates to a color management method in digital proofing, and belongs to the technical field of printing industry. Background technique [0002] In the printing industry, pre-press proofs (final contract proofs) have two main functions: to allow users to see the printing effect of the final printed matter in advance, and to confirm the design; Reference object, and use it as the test standard for the final printing effect. [0003] The production process of traditional pre-press proofs is similar to real printing, and it also needs to be separated and produced, which mainly depends on the feeling, experience and skills of the proofing operator. Not only the cost is high, but also the cycle is long and the efficiency is low. Digital proofing is an efficient and high-quality advanced working method for making pre-press proofs, and has become the main way of making pre-press proofs in the printing industry. [0004] Digital proofing is a ...
