Terms and definitions also apply to this section.
3.1
A MPR code that associates digital media files such as audio and video with printed graphics to meet the reader's needs for reading and listening, by MPR
It is composed of printed matter such as newspapers and periodicals, and digital media files such as audio and video.
[CY/T 58.1-2009, 3.1]
3.2
The matrix type 2D barcode is used as a structure to associate digital media files such as audio and video related to printed graphics, so that the reader can read the same
The digital code of the relevant electronic media content can be simultaneously listened to or viewed by other electronic devices.
[CY/T 58.1-2009, 3.2]
CY/T 58.4-2009
3.3
A plate used to print MPR code symbols.
4 MPR code printing quality requirements
4.1 Typesetting requirements
The layout of the MPR code version shall comply with the requirements of 4.4.2 of CY/T 58.3-2009.
4.2 Printing requirements
MPR code layout can't have any noise or dirty spots.
MPR code exposure time should be less than other color plate exposure time, exposure time can be controlled by measuring bar (measurement bar application reference
GB/T 18720). The code points of all MPR code symbols in the MPR code color separation chip should be clear and without missing, and the MPR code symbols can be read.
The MPR code version of the Internet access point should reach. 2% of the outlets can be displayed, and 3% of the outlets are intact.
4.3 Printing requirements
4.3.1 Equipment conditions
The MPR code can be printed under normal printing conditions.
When using four-color printing, the graphic is printed in C-M-Y version, and the MPR pattern is printed in K version.
When using five-color printing, the five colors are C-M-Y-spot color-K, in which the graphic is printed in C-M-Y-special color, and the MPR code is in K version.
print. Spot colors are formulated in proportion to CMY inks.
4.3.2 Printing color sequence
In order to ensure the printing quality of the MPR code, the MPR code should be adjusted to the final color sequence during color printing.
4.3.3 Print quality requirements
MPR code point printing should meet the following quality requirements.
--- code point shape. approximately circular;
--- code point size. diameter 60μm ± 20μm;
---Black solid density. should meet the quality requirements of 4.1.1 fine prints in CY/T 5-1999;
--- Field density tolerance. should meet the requirements of 4.6.1 of CY/T 5-1999;
--- Code point ink color. full, no missing;
---The code point has no obvious hollow, ghosting and corners;
---The layout has no obvious noise and pollution.
In monochrome printing, batch printing is only required after the test print has passed the test.
In color printing, the K version of the proofing machine should be used separately, and the other colors should be overprinted after passing the inspection.
Use the dot reading method (see 5.2.3.2) to detect the printed product. The decoding quality should reach 4.0 (A) level in Table 2 of CY/T 58.1-2009.
No. Contrast, printing increments, and axial inconsistencies should be no less than 1.0 (D).

---Infrared transmittance. < 0.06;
--- Surface roughness. 3.2μm ~ 5.6μm (surface roughness test should meet the requirements of GB/T 7973).
CY/T 58.4-2009
Field density and transmittance measurements should be measured using infrared light with a wavelength of 850 μm ± 20 μm.

a) MPR code printing quality detector;
b) density meter;
c) ≥ 100 times magnifying glass.
5.2 MPR code point quality detection
5.2.1 Plate MPR code point quality inspection
When the color separation sheet is completed, the quality of the MPR code point should be detected.
5.2.2 Printed MPR code point quality inspection
In batch printing, the number of printed large pages is not less than one per order; the inspection of finished batches is carried out in accordance with CY/T 12 regulations.
sampling.
5.2.3 Detection method
5.2.3.1 Measurement and control strip method
Tested in accordance with the requirements of GB/T 18720.
5.2.3.2 Point reading method
Use the MPR code print quality detector to detect the color separation film or print, in the upper, lower, left, right and middle areas of the sample to be tested,
The different points of each region are detected 3 times, and the arithmetic mean of the symbol quality parameters obtained by 3 tests is taken, and according to CY/T 58.1-2009
Table 2 determines the quality level.
5.2.3.3 Visual inspection
Using a 100x magnifying glass, visually detect the print quality of the MPR code.
