ISO 2846

The ISO 2846 is an ISO standard , the color and transparency of printing ink sets for four-color printing describes. It is a successor to the Euroscale , the US standard SWOP (Specification for Web Offset Publications) and the Japanese Japan Colors SF 90 standard for printing inks. The ISO 2846 is aimed primarily at manufacturers of printing inks and is a laboratory standard, the results of which are achieved with test printing machines and evaluated on standard paper and under defined lighting conditions.

The ISO 12647 refers to this standard and implements them for practical requirements.

The standard consists of several parts:

• Part 1: sheet-fed offset printing and heatset web offset printing
• Part 2: Coldset web offset printing
• Part 3: Illustration gravure
• Part 4: screen printing
• Part 5: flexographic printing

The use of ISO designations in technical colloquial language has not yet caught on; the term Euroscale continues to be used as a rule .
