Double-sided printing
Selecting the double-sided printing option will provide you with guidance and help specific to double-sided
printing during the load process.
The roll-to-roll configuration is recommended for double-sided printing. You cannot perform double-sided
printing if the dual-roll spindle or the ink collector kit is in use.
A double-sided job must be defined as a pair of images.
● Side A is the first image to be printed.
● Side B is the second image to be printed, on the reverse of Side A.
On Side A, after each row of images a black continuous line called a “registration line” is automatically
printed: (a) and (b) below. These registration lines are used while printing Side B to minimize any registration
errors in the direction of substrate movement.
When the whole of Side A has been printed, a space (c) is normally left blank for calibrations (the substrate is
already warmed up), and a further space (d) is left blank so that the substrate can be loaded for printing Side
B. However, these blank spaces are optional: you can turn them off.
