Abstract

A method of creating a bitmap for a printing plate, including defining an area of an image intended to print with a solid color, applying a halftone screen to the defined solid color area, and creating the bitmap embodying the halftone screen in the defined solid color area. The halftone screen pattern includes a plurality of dashes with a plus or minus 45-degree orientation, a plus or minus 135-degree orientation, or a combination of two or more plus or minus 45-degree and 135-degree orientations. Each dash or component dash thereof has a same number of two or more adjacent touching pixels in length and a number of one or more adjacent touching pixels in width, or the dashes are orthogonally arranged in rows and columns, or a combination thereof. Masks, plates, processes for making them, and print methods using the bitmaps are also described.
