As offset prints high definition line screen as standard, it is possible to print a higher gamut of colors with a standardized four-color process. This is also true of extended gamut processes such as Equinox by Esko. When printing in an extended gamut perfect registration becomes crucial. Offset can guarantee an extremely tight register when printing, ideal for jobs such as barcodes that incorporate more than one color. Offset printing doesn’t require anilox rollers to determine ink volumes. The volume of ink can vary across the width of the web depending on where it is needed by opening and closing the ink keys. This means that only one print unit is required when producing both solid blocks and fine detail with a particular color in the image.
