For the sample, select 5 bar code symbols with a magnification factor of 0.8 (and parallel to the printing direction (or multiplied by the vertical direction), take the middle position of each bar code symbol in the group in the bar height direction, and use the instrument that meets the requirements of 6.4.1 to measure the actual size deviation of each bar code symbol. 4
GBT18805—2002
V, where is the sample end number, 2 is the value of 12, ... 5: is the shortened number of each bar in the bar code symbol, and the value of is 1.2, 3065 to determine the width compensation value (BWC)
For the actual size deviation of all bars measured according to 6.4.2.Sum, and then divide by the number of all strips to calculate the average value of the actual size deviation of the sample strips in this group. The calculation formula is as follows: 5 X 30
Measured, strip width compensation plate BWC =!
6.6 Adjustment of the small gain magnification coefficient (Mf)
6.6.1 Determine the corresponding small gain magnification factor (Mf) for each sample. Subtract the 7 obtained in 6.5 from the actual size deviation of all strips measured in 4.2 to obtain the change in the actual size deviation of each strip:
A..nV..o-
For the sample of 2011, take the maximum value and the minimum value of the actual size difference change V of the 3U strips it contains, find the range of the printing increment change of the sample, and then look up Table 1 to obtain the Mann calculated based on the sample under the printing system
6.6.2 Determine the Mann calculated based on the sample under the printing system The allowable amount of small effect () is compared with the results of the data in 6.6.1 for each sample. The largest amount is taken as the starting point for the allowed printing bar code symbol under this printing property. The maximum change in the printing profit increment () is taken from Table 7. The amount of small effect (M) used in the printing ring is taken from Table 7. Usually, the efficiency institute will calculate the average size gain of each symbol in the empty code format, and then perform arithmetic averaging on the average gain of each symbol and the average environment gain to obtain the average value F of the above-mentioned size gain. When >G, the recording height under the brushless condition is small, and the BW in this formula is generally effective in reducing BW: When V0, the bar energy under this printing condition should increase. At this time, BWC is the increase BWI5

Degradation 1)
Allow use According to the BWC determined in 6.5 and the Mar determined in 6.6, make a bar code film or bar code symbol computer graphic document that meets the requirements of 4.3 for verification, and make a plate with this film or graphic document, and print it under the same conditions as the test printing station. And sample inspection, if the bar space size difference of the inspected print meets the requirements of GR12904, and the bar size difference is symmetrical, then confirm the BWC and Mn parallel to the printing direction under this printing condition. Before that, the predetermined width compensation and the minimum allowable enlargement coefficient should be adjusted according to the inspection results of the verification print.
6. Selection method of samples to be inspected
In the group of bar code symbols with a magnification factor of (.S) selected in Article B.4.2, when the situation before the inspection of the inspected equipment appears, a group of bar code symbols with a magnification factor of 0.85 and parallel (or perpendicular) to the printing direction should be selected. When the bar code symbols with a magnification factor of L.35 also appear in the inspection of the inspection equipment, a group of bar code symbols with a magnification factor of L.90 and parallel (perpendicular) to the printing direction should be selected. After the samples to be inspected are determined, the HW center and the HW center under the printing conditions shall be determined according to the methods specified in 6.4.2, 6.5, 6.6 and 6.7 of this standard.
The test method 7, 1 is the slow printing speed test method. The plate making, printing and sampling methods of the printing suitability test are the same as those in 6.1.6.2 and 6.3 of the printing suitability test method. 2 Determination of the suitability grade of a single sample Use an amplification of not less than 10 times to check each group of suitability grades in the sample one by one, and find out the suitability grade where the suitability lines are in contact with each other, which is the current suitability grade of the bar. When making suitability grade judgments, any failure that occurs spontaneously is not taken into account. If 5% or more of the line length is completely in contact with each other, the lines are considered to be in contact. The suitability grade can be defined as a single grade, which can be a range of grades. There may be special cases in the determination of suitability level. For example, if the A~D level suitability bars of a sample are all clear, and the space between the E~K level bars is completely filled with oil, in this case, the printing suitability level should be determined as: A~D level suitability bars of a sample are all clear, the space between the G~K level bars is completely filled with oil, and the E~P level bars begin to touch. The printing suitability level range is E--F. 7.3 Determination of overall suitability of samples GB/T188052002 According to the determination results of the individual sample suitability level, the suitability level that can be achieved by 3 or more samples is the overall suitability level of the sample.
7.4 Predetermination of barcode density reduction
Based on the determined sample overall suitability level, refer to Table 2 or Table 3 to determine the barcode film design parameters under different printing conditions.
7.5 Confirmation and verification test and correction
Use the results of 7.4 to make a verification barcode film or barcode symbol computer graphic file, use this film or graphic file to make a plate, and conduct confirmation and verification tests and corrections according to the method in 6. Table 2 Non-flexible quality printing
