I now screen print my wallpapers. Flat bed hand screen printing is ideally suited for lower volume production and sampling, and often used by makers like myself. Screen printing is still used by higher volume printers. With rotary printing the squeegee rotates inside a cylindrical screen. The design is wrapped around the cylinder, so this process can only print designs with shorter repeats. See https://www.youtube.com/watch?v=R04Dbm3ZRAE In the flat bed Buser printing process flat screens alongside each print different colours of the same design simultaneously. Like the rotary process, the paper or fabric move underneath the screens. See https://www.youtube.com/watch?v=fiMLrr_PoP8
Both these compete with digital and other processes. The larger scale of hand printing processes – both screen and block – allow for more complex designs with longer repeats; though digital printing can do this too its bland surface often disappoints.
