In order to ensure uniform ink color

In order to ensure uniform ink color, it is best to avoid slender blank sunroofs in the direction of rotation of the drum in the middle of the solid part or shaded part. Because the printing machine's ink mixing ability is limited, along the slender sunroof of the rotation direction of the printing cylinder, the upper and lower ends of the skylight will become darker after printing, which will seriously affect the appearance of printed products. If this skylight is not within the shape of the finished product, consider making it a mesh or field that is the same or similar to the perimeter, or if possible, rotate the entire pattern 90°.


Similarly, the printing plates of printing and packaging products are often made up of multiple packagings that are cross-stitched together, and slender spaces are often seen at the connecting places. For these blank spaces, the same proportion of dots as the surrounding area should be used as far as possible. Fill it in the field.
