Introduction

In line with GB/T 30329 Ben different four-color ink set portion (including proofing and print production) on the same substrate in an appropriate when printing ink film thickness, color similar to that produced. Such separation can be offset from the known reference color be simplified repeating the same printing Multicolor printing setting image.

It should be noted that only when printed on the reference substrate in order to achieve color characteristics specified in this part. However, if two inks in group Printing similar effect on the quasi-substrate, its effect on other printing substrates must also be similar. This is the development of industry standards or standard Prospective basis, such as the provisions of these inks on substrates other color GB/T 17934.2 and the like.

ISO 2846-1:2006 specified color is based on the measurement results of a large number of European, Japanese and US commercial production of ink composition and customized. GB/T 30329 This section basically retained the ISO 2846-1:2006 structure and content, but based on China's national conditions, in with ISO 2846-1:2006 parameter definitions and test methods on a consistent basis, to the domestic market at home and abroad commonly used to collect 23 sets Sheetfed offset inks and seven sets of heatset web offset inks for color measurement data, obtained the domestic market ink color and ISO 2846-1:2006 international standard color difference between the parameters as follows.

Domestic market ink yellow. a value (approximately -2.0) greenish phase Magenta ink domestic market. b values \u200b\u200b(about -1.8) with bluish Green Ink domestic market. a value (approximately -2.4) greenish phase Domestic market ink black. b value (about 3.0) yellow phase Domestic market inks yellow, green L value (about 2.0) clear and high, the domestic market magenta ink, black L values \u200b\u200bsimilar to international standards.

GB/T 30329 in this section based on the testing process and domestic technical data presented is consistent with China's color standard.

Printing four-color printing ink color and transparency Part 1. sheetfed and heatset web offset printing

1 Scope

GB/T 30329 provisions of this part of the four-color offset printing ink colors used in offset printing and proofing process should meet the color and transparency Degree feature also provides the printing conditions (using laboratory printability tester), defined substrates and ensure consistency of testing methods.

This section applies to sheetfed, heatset web offset printing and photo-curable.

This section does not apply to fluorescent inks, pigments (or spectral characteristics indicative except information) is not specified, so that the optimal combination of different pigments You can also reach the chromaticity requirements specified in this part.
