The work of preparing International Standards is normally carr

11、ied out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

12、ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the differen

13、t approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be

17、 commercial and industrial production: Part 1: Measurement methods and reporting schemaThe following parts are under preparation: Part 2: Commercial production printingiv ISO 2016 All rights reservedPD ISO/TS 15311-1:2016ISO/TS 15311-1:2016(E)IntroductionWhen producing a colour reproduction, it is i

18、mportant that the persons responsible for data creation, colour separation, proofing and printing operations have previously agreed a minimum set of parameters that define the visual characteristics and other technical properties of the planned print product. This part of ISO/TS 15311 identifies a n

19、umber of metrics that can be applied to printed sheets and that can be used as the basis for such communication. The range of metrics is large and it is not intended that all of these metrics are to be applied to any given printed product and for any given application, the range of metrics is to be

20、carefully selected, for example based on subsequent parts of ISO/TS 15311.The metrics described by this part of ISO/TS 15311 can be applied to any type of print. They are likely to most often be applied to digitally printed prints.When selecting the set of metrics, only those metrics that have a cle

21、ar specification and that correlate well with human perception are included in this part of ISO/TS 15311. Since this is an area of significant research activity, new metrics are expected to emerge and existing metrics to be revised in the next few years. For this reason, we anticipate the need to re

22、vise this part of ISO/TS 15311 within a very short time scale as new metrics are tested and found to be reliable.Additional tests to those specified in this this part of ISO/TS 15311, for example visual assessment of smoothness, images and other elements may be required when assessing print quality.

23、As with any parameter that is used as part of a product specification, it is important for readers to understand clearly what the metric means. For this reason, a reporting schema is to be followed when reporting measurements in conformance with this part of ISO/TS 15311. ISO 2016 All rights reserve

32、-1:2016(E)3 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.3.1achromatic colourperceived colour of low chroma, in the perceptual senseNote 1 to entry: The colour names “white”, “grey” and “black” are commonly used for objects that reflect light. For

33、 objects that transmit light, the words “colourless” and “neutral” are used.Note 2 to entry: In printing practice, achromatic colours can be produced either by a single black ink or three chromatic (and one achromatic) inks suitably balanced.Note 3 to entry: Colours with low chroma are also called n

34、ear neutral colours.3.2bandingappearance of one dimensional bands within an area that should be homogeneousNote 1 to entry: This is also known as streakiness, while the artefacts are called streaks, bands, or stripes.Note 2 to entry: Adapted from ISO 24790.3.3CIEDE2000 colour differencetotal colour

35、difference as defined in ISO/CIE 11664-6:2014 (CIE S 014-6/E:2013)Note 1 to entry: The unit is E00. The default weights for lightness, chroma and hue are (1:1:1).3.4colour deviationdifference between the colour aim value and the mean of a set of colour measurements3.5colour variationcolour differenc

36、e from the mean of a set of colour measurementsNote 1 to entry: Colour variation is also known as colour fluctuation and may be reported as the mean or 95 percentile.3.6digital printprint where the image is printed directly from the digital domainNote 1 to entry: Digital printing is a process for te

37、xt and image reproduction with a colour marker on a medium using a marking device, on which the marking information is generated from digital data directly to the medium. It differs from traditional ink-based printing on which the marking information is generated from a form produced offline prior t

41、tric and/or densitometric aim valuesNote 1 to entry: Such parameters usually include (as a minimum) printing process, paper category, printing ink, screening and printing sequence. The aim values typically comprise the colorant description and tone value increase aims.Note 2 to entry: For the purpos

42、es of colour management, a printing condition is fully characterized by giving the relationship between the CMYK digital input values (as stipulated in ISO 12642-2) and the corresponding measured colorimetric values.Note 3 to entry: Based on a given set of characterization data according to 3.9, Not

The tone value of a pixel is typically computed from the fo

45、rmula.4 Requirements4.1 GeneralThe following subclauses provide a number of metrics that define attributes of printed sheets and requirements for reporting them.In many cases, the existing standards use CIE Eabrather than CIEDE2000. Although these are not interchangeable quantities, Eabhas been supe

46、rseded by CIEDE2000 in ISO/TC 130 standards. For this reason, CIEDE2000 shall be used to report colour difference metrics in this part of ISO/TS 15311.Similarly, printing density is seldom used to measure colour and where the referenced standards specify printing density, approximately equivalent CI

47、ELAB colour measurements shall be used.

48、metrics for a set of sheets; for example, the set of sheets produced in a single print run or the set of sheets to be delivered as part of an order for print. In these cases, it is important to be able to indicate the likely variation across the entire set of sheets.Sheets should be selected randoml

49、y with no replacement.Samples should be selected with the following provisos:a) sheets should be selected throughout the entire press run;b) sheets should not be selected synchronous to any press event, e.g. at each roll change or after every blanket wash.In cases where metrics are reported for a set of sheets, the report shall indicate the following: the total number of sheets in the set to be assessed, the number of sheets measured and, unless random selection with no replacement is
