1 Scope 108

This International Standard specifies the list of paper substrate relevant properties to be communicated 109 between the paper and the printing industries. 110

This International Standard is applicable to papers intended to be printed in rotogravure, cold-set web offset, 111 heat-set web offset, sheet-fed offset, and flexographic printing processes and to proofing substrates. 112

Where multiple measures exist the preferred procedure and its International Standard is defined. 113

All measuring methods of properties specified in this International Standard are described in ISO Standards. 114

2 Normative references 115

Paperdam understanding on how to use ISO 15397

§  QUOTE OF INTRODUCTION (1)

§  This International Standard is intended to improve communication between the graphic papermaking industry and the printing industry based on their need to be able to produce quality printing. Paper properties and how they are measured are presented and their use in the printing context is described.

§  This International Standard describes data to be provided for

reliable printing. A substrate description can be assessed to be in conformance with this International Standard, not a substrate itself.

6 Luc LANAT TC 6 Delft 2014 04 08


QUOTE OF INTRODUCTION (2)

§  Printing press settings depend on paper grade, and several paper properties are required in order to define a grade.!

§  Paper measurement standards developed within ISO/TC 6 are referenced in this International Standard. They were mainly used to develop paper industry test methods and allow the papermaking processes to be reproducible and reliable within paper mills. It is advisable that paper purchasing specifications be based on paper industry standards. This recommendation also applies to paper proofing substrates. Special requirements for paper substrates for the reliable production of printed products need to be communicated on the basis of standards developed by ISO/TC 6 whenever possible.!




§  The evaluation of colour of the unprinted paper is critical to define prepress white point settings. This measurement can be performed with either diffuse:0° integrating sphere instruments (papermakers’ equipment) or 45°:0° instruments (printers’ equipment). Results are often close if the UV calibration is performed correctly. This International Standard specifies 45°:0° instruments (printers’ equipment) to perform this evaluation as per ISO 13655, because of their wide availability at printers' facilities.!

§  For the evaluation of printed colours, measurement devices are developed according to ISO 13655 which differ from the colour measurement devices which conform to ISO 2469 and ISO 5631-1, ISO 5631-2 and ISO 5631-3. The latter type of instrument is used within paper mills for quality evaluation during paper manufacturing and unprinted paper colour evaluation.!




§  Properties linked to the printing process (e.g. dimensions, blistering and picking resistance in offset, missing dots in gravure) are not described in this International Standard, since they are implicitly needed when purchasing the paper meant for this printing process.!

§  Properties that are not based on ISO standards are not described here.!

§  The bibliography lists basic references in graphic technology standards,[1][2] Paper and board standards,[3] previously published references,[4] commercial classifications,[5] conditions of sale,[6] and reference lists of printing characterization data publicly available.[8]



Paperdam understanding on how to use ISO 15397

§  Companies can use ISO15397 as guidance for implicit customer requirements in the sense of ISO 9000 series.

§  Clause 4 is titled «List of required criteria for communication of paper properties». This list of properties communicated may relate to a product family or a specific brand named product. The recommended wording is « List of properties as per ISO 15397 criteria ».

§  A « company » as such cannot claim to be in conformance with this standard or compliant to ISO 15397.

§  Third parties may assess conformance of communication to ISO 15397. §  Companies may choose to use it for its communication or not, meaning that

the list of properties communicated will be conforming to ISO 15397 list of required criteria or not.

§  As any other ISO standard, ISO 15397 is of voluntary application.



Paperdam Scope

§  The objects of the foundation, hereinafter referred to as "Paperdam" are to contribute to the role of paper as a product within international standardisation. The main working area, but not excluding other areas, is in the graphic technology.

§  Paperdam acts as per ISO (International Organization for Standardization) Global Relevance Policy as documented and published by ISO.

§  Paperdam can organize and sponsor exhibitions, conferences, studies or other activities within the scope of its objects.

§  The following subjects shall not be discussed during any meetings or contacts on behalf of Paperdam: 1. Sales and purchase prices, including price changes or pricing policy. 2. Discounts, rebates, allowances or other factors affecting sales or purchase prices. 3. The commercial terms or conditions of sale or purchase. 4. Production output, capacity, capacity utilization rates or changes in output, capacity or capacity utilization rates. 5. Individualized sales/order figures or customer lists. 6. Production, marketing, Research and development or other costs. 7. Investments, production, product development or marketing polices or plans. 8. Research and development plans or results. 9. Stock levels. 10. Allocation of customers. 11. Sales territories. 12. Market sharing. 13. Sharing of sources of supply.
