Embodiment Construction

[0058] The invention discloses a standardized color management method for packaging and printing paper, which includes the following steps:

[0059] (1) Standard proofs for printing:

[0060] Take the standard paper 128g space shuttle coated paper;

[0061] Follow the ISO 12647-2:2013 standard and adopt the Fogra51 data target;

[0062]Measuring conditions: M1, White Backing, D50 / 2;

[0063] Ink: Four-color ink conforms to the standard of ISO2846-1;

[0064] Environment: temperature 22-25℃; humidity 55-60%;

[0065] The IT8 color gamut guide table is laid out on the test layout, and the P2P table is used for data acquisition; the color control bar and image are used for reference and comparison of the main standards and control points before printing: the restoration of the dots on the printing plate is 1%-99%, and the printing plate The dot restoration on the screen and the dot error of the original is ±0.5%; the position of the color control bar must be perpendicular to ...

Abstract

The invention discloses a standardized color management method and device for packaging printing paper. The method comprises the following steps of: (1) printing a standard specimen page; (2) printinga contrast specimen page; (3) formulating a color gamut improvement scheme: analyzing color gamut difference and combining with the evaluation of PressSIGN software, and passing through the followingsteps: (3.1) setting a dot shape before printing; (3.2) setting a publication compensation curve before printing; (3.3) correcting output data of Y-version publication compensation in shallow screentone by using Prinergy Harmony software; (3.4) adjusting the hue of ink; (4) implementing a new single powder card color gamut specimen page by using a G7 method printing measure; and (5) using new data for modeling. By adopting the method and the device, the printing color gamut is expanded by more than 25% and is closer to the standard printing effect, so that the standard draft of a designer can be reproduced in single powder card packaging printing, and the use requirements are met.

Description

technical field [0001] The invention relates to the technology in the printing field, in particular to a standardized color management method for packaging and printing paper. Background technique [0002] In modern society, the growth of packaging printing has exceeded the printing of book publications. Due to historical reasons, the standards of all designers, publishers, and printers are formulated in the environment and process of books and periodicals. Taking the printing international standard ISO12647-2 as an example, the listed papers include coated paper (copper plate), uncoated offset paper and newsprint. However, the most widely used single-powder (coated white cardboard) paper and coated gray cardboard have no corresponding standards for packaging printing. [0003] As can be seen from Table 1 and Table 2 below, due to the hue (yellowish) of the single-powder jammed paper, the data such as ink overprinting does not meet the standard ISO12647-2 specification. A...
