Lines Of Anilox Roller

The number of lines of the anilox roller refers to the number of ink holes per unit length on the surface of the anilox roller. It is also one of the important parameters of the anilox roller. It also has a very important influence on the ink transfer performance of the anilox roller. Generally speaking, the higher the number of lines of the anilox roller, the smaller the ink transfer volume, and vice versa. In addition, the number of lines of the anilox roll also determines its own scope of application. Generally speaking, when printing large areas of solid color blocks or images that are not too demanding, you can consider using a low-line anilox roller, for example, when printing a solid area, you can use an anilox roller of about 360 lines/inch. On the contrary, when printing fine images or small text and lines, an anilox roller with a relatively high number of lines should be used to prevent the small dots in the highlight area from being immersed in the ink hole and causing serious expansion of the tone value, or extremely fine The lines become thicker. However, the number of lines of the anilox roll should not be too high. If the number of lines of the anilox roll is too high, it will not only cause certain difficulties in the processing technology of the anilox roll, but also, due to the mesh wall of the high-line count anilox roll When the thickness becomes thinner, the strength will be reduced and damage is prone to occur. In other words, if the number of threads of the anilox roll is too high, its service life will be shortened accordingly. Generally speaking, the number of lines of the anilox roller should be four or five times the number of screen lines added to the printing job. Of course, it also depends on the actual production of the printed image.
