The Physics of Subtractive Color and Optical Inset (Choke)
In commercial textile decoration, white underbase execution determines print perfection. If a digital file has fine text or floating elements, the white base must be precisely "choked" (inset inward by 1 to 2 pixels) relative to the colored artwork.
If the white base is identical in size to the color artwork, microscopic mechanical movement or fabric stretch under the heat press causes the white underbase to peek out from behind the colored edges, creating an amateur white outline error known as registration drift.
NexelPrint’s automated RIP raster processing software calculates mathematical choke curves for every print, guaranteeing that the white underbase remains 100% invisible behind the top artwork.
