2. The relationship between the cell volume and the cell depth. Under normal circumstances, the album printing for a certain number of anilox roller, the network volume and the depth of the network hole should maintain a reasonable relationship. With the increase of the depth h of the cell, the volume of the cell site should increase accordingly.
The reasonable range of network lines and ink loading
The metering function of the anilox roller on the one hand shows that the amount of ink carried can be obtained by changing the number of screen lines. On the other hand, for the same number of anilox rollers, the depth of the screen can be changed or the screen can be changed. The ratio of the opening of the cavity to the wall to obtain different ink loading. For the anilox roller manufacturers, due to the different precision grades of the user's book printing flexographic printers, the different absorption performances of the album printing substrates, and the most different transmission of inks on the layout, the user should provide the same number of screens. The most different anilox rollers for ink transfer are available for users to choose. Similarly, the manufacturer can also recommend the user to use different anilox roller number according to the user's specific situation according to the user's requirements for ink loading. From this point of view, the rational selection of the number of anilox roller screens and ink carrying trays is a more complicated issue. Manufacturers and users should fully negotiate and explore the number of screen lines.
The following two specific methods are recommended in the application:
(1) If the user proposes a certain number of lines of the anilox roller, the manufacturer can find out the corresponding ideal ink-carrying capacity according to this line number, and then print out the precision of the flexographic printing machine according to the user's picture album, and absorb the printing material. The size of the performance and the amount of ink needed to transfer ink to determine the actual amount of ink carried, that is, according to the size of the ink to sculpt the number of network points of the network. In other words, taking the ideal ink-carrying curve as the reference standard, when the machine has high precision, the printing material has low absorption, and the required ink transfer amount is small, it can be carved at a lower ink-carrying amount; High ink load is engraved. If you still can not meet the user's requirements, indicating that the number of proposed network lines is not reasonable, then we must change the number of screen lines.
(2) If the user can specify the specific amount of ink, and the number of screen lines can be determined by the manufacturer, then the manufacturer can determine the number of screen lines corresponding to the ideal curve according to the value of the ink-carrying capacity, and then put it according to the user's specific situation The correction value of ink loading (method is same as 1). According to the above method to determine the number of lines and the amount of ink, generally better meet the requirements. Therefore, the reasonable determination of the number of printing screens and the amount of ink to be loaded requires the user and the manufacturer to agree on each other.
