18、15311-1:2016(E) Introduction When producing a colour reproduction, it is important 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 propert

19、ies of the planned print product. This part of ISO/TS 15311 identifies a number 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 pri

20、nted product and for any given application, the range of metrics is to be 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 p

21、rints. When selecting the set of metrics, only those metrics that have a clear 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

22、revised in the next few years. For this reason, we anticipate the need to revise 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 smooth

23、ness, images and other elements may be required when assessing print quality. 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 measureme

24、nts in conformance with this part of ISO/TS 15311.

Guidance as to which of these metrics to apply to any given category of product along with acceptable conformance criteria is provided in subsequent parts o

Although this part of ISO/TS 15311 is expected to be used primarily to measure prints from digital printing systems, the metrics are general and can be applied to other kinds of print. 2 Normative references The following documents, in whole or in part, are normatively referenced in

33、ntry: The colour names “white”, “grey” and “black” are commonly used for objects that reflect light. For 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 chromat

34、ic (and one achromatic) inks suitably balanced. Note 3 to entry: Colours with low chroma are also called near neutral colours. 3.2 banding appearance of one dimensional bands within an area that should be homogeneous Note 1 to entry: This is also known as streakiness, while the artefacts are called

35、streaks, bands, or stripes. Note 2 to entry: Adapted from ISO 24790. 3.3 CIEDE2000 colour difference total colour 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). 3.4 colour deviation d

36、ifference between the colour aim value and the mean of a set of colour measurements 3.5 colour variation colour difference from the mean of a set of colour measurements Note 1 to entry: Colour variation is also known as colour fluctuation and may be reported as the mean or 95 percentile. 3.6 digital

37、 print print where the image is printed directly from the digital domain Note 1 to entry: Digital printing is a process for text 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

38、differs from traditional ink-based printing on which the marking information is generated from a form produced offline prior to imaging on the medium. Note 2 to entry: Adapted from ISO 18913. 3.7 permanence ability to remain chemically and physically stable over long periods of time SOURCE: ISO 1891

39、3:2012, 3.1342 ISO 2016 All rights reservedPD ISO/TS 15311-1:2016ISO/TS 15311-1:2016(E) 3.8 image quality impression of the overall merit or excellence of an image, as perceived by an observer neither associated with the act of photography, nor closely involved with the subject matter depicted Note

40、1 to entry: The purpose of defining image quality in terms of third-party (uninvolved) observers is to eliminate sources of variability that arise from more idiosyncratic aspects of image perception and pertain to attributes outside the control of imaging system designers. 3.9 printing condition set

41、 of primary process parameters which describe the conditions associated with a specific printed output, associated with spectral, colorimetric and/or densitometric aim values Note 1 to entry: Such parameters usually include (as a minimum) printing process, paper category, printing ink, screening and

42、 printing sequence. The aim values typically comprise the colorant description and tone value increase aims. Note 2 to entry: For the purposes of colour management, a printing condition is fully characterized by giving the relationship between the CMYK digital input values (as stipulated in ISO 1264

43、2-2) and the corresponding measured colorimetric values. Note 3 to entry: Based on a given set of characterization data according to 3.9, Note 2 entry and a definition of achromatic perception, a grey condition might be extracted. 3.10 tone value proportional printing value encoded in a data file an

44、d interpreted as defined in the file format specification % whereV p is the integer value of the pixel;V 0 is the integer value corresponding to a tone value of 0 %;V 100 is the integer value corresponding to a tone value of 100 %. Note 1 to entry: Tone value is expressed in units of percent. Note 2

45、 to entry: Most files store these data as 8-bit integer values, i.e. 0 to 255. The tone value of a pixel is typically computed from the formula. 4 Requirements 4.1 General The following subclauses provide a number of metrics that define attributes of printed sheets and requirements for reporting the

46、m. In many cases, the existing standards use CIE E abrather than CIEDE2000. Although these are not interchangeable quantities, E abhas been superseded 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. Simi

47、larly, printing density is seldom used to measure colour and where the referenced standards specify printing density, approximately equivalent CIELAB colour measurements shall be used. ISO 2016 All rights reserved 3PD ISO/TS 15311-1:2016ISO/TS 15311-1:2016(E) 4.2 Single or multiple sheet assessment

48、Unless otherwise specified, metrics shall be assumed to apply to the assessment of a single sheet. In many cases, it is useful to be able to report 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

49、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 randomly 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 repo
