This part of ISO/IEC 15415 - specifies two  methodologies for the measurement of  specific attributes of two-dimensional bar  code symbols, one of these being  applicable to multi-row bar code  symbologies and the other to  twodimensional matrix symbologies; -  defines methods for evaluating and grading  these measurements and deriving an overall  assessment of symbol quality; - gives  information on possible causes of deviation  from optimum grades to assist users in  taking appropriate corrective action. This  International Standard applies to those two- dimensional symbologies for which a  reference decode algorithm has been  defined, but its methodologies can be  applied partially or wholly to other similar  symbologies.

ISO/IEC 2008 – All rights reserved Page 17 Replace 7.8.4 with the following: 7.8.4 Modulation and related measurements 7.8.4.1 Modulation Modulation is a measure of the uniformity of reflectance of the dark and light modules respectively. Factors such as print growth (or loss), misplacement of a module relative to the grid intersection, the optical characteristics of the substrate and uneven printing may reduce the difference between the reflectance of a module and the Global Threshold. A low Modulation may increase the probability of a module being incorrectly identified as dark or light. The reflectance value of each module in the symbol shall be measured by superimposing on the reference grey-scale image the grid determined by applying the symbology reference decode algorithm to the binarised image. Calculate MOD, the Modulation value of each module as follows: MOD = 2 * (abs (R – GT)) / SC where MOD = modulation
R is the reflectance of the module
GT is the Global Threshold
SC is the Symbol Contrast Assign the grade level for each module according to Table 6. For each codeword, select the minimum modulation grade of all modules in the codeword. As suggested by the absolute value in the function for MOD, whether a codeword is decoded correctly has no bearing on the grade level that is assigned. In this way, Modulation differs from Reflectance Margin, see 7.8.4.3. Table 6 — Module grading for Modulation and Reflectance Margin MOD or MARGIN Module Grade ≥ 0,50 4 ≥ 0,40 3 ≥ 0,30 2 ≥ 0,20 1 < 0,20 0

ISO/IEC 2008 – All rights reserved 3 The cumulative number of codewords achieving each grade shall be counted and compared with the error correction capacity of the symbol as follows: For each grade level, assuming that all codewords not achieving that grade or a higher grade are errors, derive a notional Unused Error Correction grade as described in 7.8.8. Take the lower of the grade level and the notional UEC grade. NOTE This notional grade is not related to, and does not affect, the UEC grade for the symbol as calculated according to 7.8.8, but is a means of compensating for the extent to which error correction can mask imperfections in a symbol. If one symbol has higher error correction capacity than another symbol, then the former symbol can tolerate a greater number of codewords with low modulation than the latter. See Annex F for a fuller description of the approach. Then the Modulation grade for the symbol shall be the highest of the resulting values for all grade levels. When the symbol consists of more than one (e.g. interleaved) error correction block, each block shall be assessed independently and the lowest grade for any block shall be taken as the Modulation grade of the symbol. Table 7 shows an example of grading Modulation in a symbol containing 120 codewords, 60 of which are error correction codewords with a capacity to correct up to 30 errors in a single error correction block. Modulation grade of the symbol in the example would be 2 (the highest value in the right-hand column). Table 7 — Example of Modulation grading in a two-dimensional matrix symbol MOD codeword grade level (a) No. of codewords at level a
Cumulative no. of codewords at level a or higher (b) Remaining codewords (treated as errors) (120 - b) (c) Notional unused error correction capacity (30 – c) Notional UEC (%) Notional UEC grade(d) Lower of a or d (e) 4 25 25 95 (exceeded) <0 0 0 3 75 100 20 10 33,3% 1 1 2 15 115 5 25 83,3% 4 2 1 3 118 2 28 93,3% 4 1 0 2 120 0 30 100% 4 0
Modulation grade (Highest value of e): 2
In this example, some codewords may contain errors but that does not affect the calculation. 7.8.4.2 Contrast Uniformity Contrast Uniformity is an optional parameter that can be a useful process control tool for measuring localized contrast variations. Contrast Uniformity does not affect the overall grade. SIST EN ISO/IEC 15415:200
