Graphic technology — Image quality evaluation methods for printed matter — Part 31: Evaluation of the perceived resolution of printing systems with the Contrast–Resolution chart

This document specifies the Contrast–Resolution test chart, the requirements on the printing process needed to reproduce this test chart, the required characteristics of a high resolution scanner needed to digitize the information reproduced on printed test charts, and the requirements on the interpretation of this digitized data. It also specifies the resolution-score method for evaluating the perceptual resolution of printed material using the Contrast–Resolution test chart. The procedure specified in this document is intended for a characterization of the perceived resolution of a graphic arts production printing system using the Contrast–Resolution test chart.

Graphic technology — Processless lithographic plates — Evaluation methods for characteristics and performance
SIST ISO 24487:2024

This document applies to processless lithographic plates and specifies evaluation methods for lithographic plate characteristics, on-press development performance, usability and print image quality. It specifies measurement conditions for materials and equipment and provides guidelines for the selection of suitable processless lithographic plates by a printing organization and requirements for comparative assessment tests. The assessment of waterless lithographic plates is out of scope of this document. NOTE Some of these methods can be used for the evaluation of all classes of lithographic plate. This document specifies measurement conditions for materials and equipment and provides guidelines for the selection of suitable processless lithographic plates by a printing organization and requirements for comparative assessment tests.

Graphic technology — Methods of adjustment of the colour reproduction of a printing system to match a set of characterization data
SIST-TS ISO/TS 10128:2024

This document describes four methods for the adjustment of the digital content data that is input to a printing system to achieve consistency in the printed results among a number of presses printing to the same general aim conditions. These four methods are generally identified as: 1) matching of tone value curves (TVI and CTV), 2) use of near-neutral scales, 3) colour-optimised correction curve set, and 4) use of CMYK to CMYK multi-dimensional transforms. The procedures for establishing the aim condition for the necessary correction curves, the procedures for determining the individual correction curves, and a comparison of the applicability of these four methods are included. These adjustment procedures are intended for use with printing systems that use CMYK colourants. Such systems are not restricted to those that use traditional ink on paper printing but can involve other marking technologies such as those used for proofing and/or digital printing.

Graphic technology — Image quality evaluation methods for printed matter — Part 21: Measurement of 1D distortions of macroscopic uniformity utilizing scanning spectrophotometers

This document defines a measurement method for the evaluation of distortions in the macroscopic uniformity of printed areas that are oriented in the horizontal and vertical direction, such as streaks and bands. It provides requirements for the layout of the test form, the use of a colour measurement device taking measurements in a 2D sampling grid, and the formula to compute the Macro-Uniformity-Score. This document does not cover any non-adjacent or non-horizontal nor vertical patterns. Due to the used spatial frequency, the Macro-Uniformity-Score does not measure high frequency (fine) patterns such as missing nozzles.
