There are a number of approaches used when custom flags are printed. The screen printing process can be done via hand, machine or digital imaging.
Custom flags are usually printed with the aid of a screen printing method using materials that are common among flags such as nylon, woven polyester, knitted polyester, etc.
Initially, the design is made on the computer for the filming machine. If the flag maker incorporates 2 colors so 2 films will also be needed using the filming machine. 1 film will be needed for each color. The film is also applied with the aid of light to create the printing plate. Using 2 colors in the custom flag layout will also require 2 plates, which is generally the same as the traditional method of making photos in a dark room.
When applying colors, CMYK powder is applied to create the CMYK colors or PMS colors. These are combined using a machine and the combination 60%K, 40%Y, 30%C and 20%M is used. Cataplasm is also incorporated. When the colors are properly combined, these will be ready for application.
The flag material is then positioned on a flat surface. Huge amounts can also be placed on a machine which will take up less time and also cost less. Another option is to use a long flat bed top for small runs. This is done by hand and colors are applied one after another.
The plate is finally screened and the color dye is added properly via the open spaces of the plate and right on the custom flag fabric found underneath.
