Security Seals printing printing production requirements of what the book
One of the printing position requirements
    The location of the Security Seals symbol shall be determined by the fit without deformation, easy reading and plate making. That is, the right side of the main display surface of the commodity packaging or the plane connected to the main display surface, and the back side of the main surface of the commodity package. Think of the characteristics of the printing process, the making of the security seal should be the direction of the corresponding direction with the printing, so that the printing deformation can only watch the usual longitudinal position of the security seal to not affect the accurate reading. As the packaging, the characteristics of differences, Security Seals printing location is also different. The general box-type packaging security seal printed on the right side of the lower part of the box; canned and bottled packaging Security Seals is best printed on the side of the label below, but the Security Seals symbol surface curvature can not exceed 30 °; barrel-shaped package Security Seals the best Printed on the side of the bucket, if the side can not be printed, the security seal can be printed on the lid, but the lid can not exceed the depth of 13mm; bag-like packaging and the bottom of the larger, the security seal printed on the bottom or printed on The lower part of the back of the central; book security seals are usually printed on the back cover or cover the lower left corner, and the direction of the line with the spine in parallel. In summary, the bar code as a data input technology and automatic identification technology, commonly used in commodity packaging, it is in the consumption of goods, sales, storage and inspection, communication messages play an important role. Therefore, the correct understanding and understanding of the Security Seals of the knowledge and printed Security Seals is an important part of packaging and printing.
The pleading of the substrate
The second Security Seals ink part of the request
  As the Security Seals read, the scanning light source is 45 ° angle incident, and the reflected light collection angle of 15 °, when the reflected light beyond the 15 ° range, you can not collect the reflected light signal, which is equivalent to the black effect. Therefore, in order to meet the Security Seals to scan this feature, pleaded with the substrate has a good light scattering characteristics, and can not show specular reflection. Therefore, the white matter of paper, opacity and gloss, how to read the Security Seals have a certain impact. In addition, we should also consider the use of good weatherability, strength after the size of stability, good coloring, ink permeability, smoothness and brightness of moderate material.
Its three print quality requirements
    The security seal symbol is the source of information for scanning and reading. In order to ensure correct reading, the printed Security Seals should be clearly defined, and the article should be clear and incomplete. In order to ensure the correct reading of the Security Seals, the maximum diameter of the defects and stains on the Security Seals shall be less than or equal to 0.4 times the width of the narrowline Security Seals. After the printing of the security seals in the lines and blanks should have a clear contrast signal, the blank at the reflectivity should be as large as possible, and the line reflectivity should be as small as PCS value (color contrast) the greater the Security Seals of the contrast signal The greater the performance, the better the performance.
Its four requirements for ink specifications
     Ink color should be fully thinking about the ink color, ink color cast on the Security Seals of the impact is also great. In theory, only in accordance with the color ratio of the use of ink can meet the Security Seals printing request, but because of the presence of imprinted ink impure defects, resulting in color cast situation. Therefore, the ink should be used to control the color, so that the ink density uniformity, hue saturation, high purity, it is best in the printing Security Seals before the determination of a certain ink in the red light reflectivity can reach the request. The reflectivity and gloss of the gold ink will constitute a specular reflection effect, affecting the scanner to read, it can not be used for printing bar code. In addition, the ink concentration and the thickness of the ink layer should also be suitable for Security Seals printing request, because the security seal printing is field printing, the printing can reach the reflection density and ink optical properties and ink thickness. During the printing process, the printed reflection density increases with the thickness of the ink, and when the ink thickness reaches a certain value, the density immediately reaches the saturation state. Ordinary ink saturated density plea: black ink 1.8 ~ 2.0; cyan ink 1.45 ~ 1.70; magenta ink 1.25 ~ 1.50; yellow ink 0.90 ~ 1.05; other special Color ink 0.8 or more. Due to the difference in the printing process, the thickness of the ink layer is different, the ordinary offset is 2 ~ 4μm; the embossing is 8μm; the flexographic printing is 10μm; the gravure is 12μm
