4 Technical requirements
JB/0113-199 9
4,1 Use in accordance with 5.2.! The printed product of the plate should be able to reflect the gradation of the plate, the ink color should be uniform, the dots should be clear and firm, and there should be no obvious "mother".
4,z The weight difference of two proofs of the same printing plate should not exceed 0.05mm. 4.3 The uniformity error of the proof should not exceed 8% for the whole sheet, and not less than 6% for the double and four-page. 4.4 Under the condition of environmental humidity of (20±5]T and relative humidity of [65±101%, the temperature control device should be able to make the humidity of the plate lower than the surrounding humidity (5~15), and ensure that the temperature change of the plate surface is not more than 4, 4.5 The paper platform and the corners of the plate half should be The height should be able to be adjusted as a whole and individually. The adjustment error is as specified in Table 2. Table 2 Adjustment error
Measurement method
Paper washing grid
Double, 4 yuan
4.6 The operating noise of the offset proofing machine shall not exceed 82dB (A) 5 Test method
5.1 Speed ​​
5.1.1 Use formula (1) to calculate the average speed of the flow rack operation 1: S
In the formula: The average speed of the flow rack operation, ms
S--the one-way distance moved by the roll rack from starting to stopping, m--the single-trip time required for the roll rack from starting to stopping, 5 yuan 5.1.2 The one-way time of operation is measured with a shift meter. 5.2 Printing Master
Welcome
5.2.1 Use a screen line plate with 60 lines/m or more and 50% dot. The total screen area should account for more than 70% of the maximum printing surface: set three "cross" lines at a distance of about 40mm from the edge of the printing plate. The line width is about 0.10mm and the length is about 20mm.
5.2.1 Use red oil to print at 120~ Proof on 150g/m2 paper, take 10 samples in succession, check the proofs with a 10x magnifying glass, and use a reading magnifying glass with a measurement accuracy of 0.10.m to measure the width of the "cross" line pattern at each position according to Figure 1, and calculate the arithmetic mean of the width of each position of the 10 sheets: 5.2.3 Proof 20 sheets twice in succession, and record the width of the 1-\ cross line at the front of each sheet according to Figure 1. The net width of the cross line at the same position as 5.2.2:
5.2.4 The average value of the line width at each position of the two proofs minus the line width at the corresponding position of the first proof is the coincidence error, and the result should meet the requirements of 4.2.
5.2.5 When proofing the full version, adjust the density to stabilize within the range of 1.31.5: Take 3 samples in succession, and use formula 12) to calculate the average of the cover layer 2www.bzxz.net
Uniform error 1. The result should be equal to 4.3 zero requirement, JB/T9113-1999
Where: D each measuring point gradually measured disk value [12,--12) measuring points are evenly distributed on the printed product F; density average value "F
Figure 1 standard line
5.3 Use a temperature juice with a precision of 0.1 to measure the humidity at the four corners and the center of the display table. The measuring points shall not be less than 5, and the result shall meet the requirements of Table 4,4 .
5.4 Use plates with a size of 0.20mm and 0.80mm to conduct adaptability tests respectively. The roller frame should be able to pass the test under the table pressure condition. 5.5 Adjustment error of paper platform and plate platform
5.5.1 Use a dial indicator to measure the four corners of the mother paper platform and the plate platform. After adjusting the indication values ​​of the four corners separately, observe the indication values ​​of the four corners. 5.5.2 Use a dial indicator to measure the four corners of the mother paper platform and the plate platform. The overall adjustment from low to high is 1mm. The maximum measured value is the material adjustment error.
5. (Use a level meter to measure A city, level meter, the height of the measuring point is half of the sum of the machine height and 1m. The 4 measuring points are located on the center line of the machine. The fifth point is the maximum noise point of the patrol measurement. The arithmetic average of the measured values ​​of the 5 points is taken as the machine noise, which should comply with the provisions of AF.
6 Inspection rules
Each production unit should strictly follow the bidding channel regulations. All the contents specified shall be checked item by item. Only after all items are qualified can the product be issued with a certificate of conformity! 7 Marking
