This document specifies the colour and transparency characteristics that are to be met by each ink in a process colour ink set intended for proof and production printing using offset lithography. The specified printing conditions (which use a laboratory printability tester), the defined substrate and a method for testing to ensure conformance are also defined. Characteristics are specified for inks used for sheet-fed, heat-set web and radiation-curing processes.
This document does not apply to fluorescent inks and it does not specify pigments (or spectral characteristics — except informatively) in order not to preclude developments which may enable different pigment combinations to be used advantageously while still achieving the colorimetric requirements specified in this document.rd edition 2017-08 Graphic technology — Colour and transparency of printing ink sets for four-colour printing — Part 1: Sheet-fed and heat-set web offset lithographic printing Technologie graphique — Couleur et transparence des gammes d’encre d’impression en quadrichromie — Partie 1: Impression lithographique offset sur feuilles et à bobines Reference number ISO 2846-1:2017(E) ？ ISO 2017 ISO 2846-1: 標(biāo)準(zhǔn)截圖
