This article explains what the print_overlap variable does and how to change it.
You can change the print_overlap variable from the Printer Options menu in the ARC software under Utilities > Processing Options. It looks like this:
The print_overlap variable controls how much ink is deposited by the printers cartridges when printing. print_overlap can be any odd integer less than 103. For porous materials we recommend setting print_overlap to 43. For nonporous materials we recommend setting it to 63.
The higher print_overlap is the more silver will be deposited per layer but a by-product of this is that more liquid by-product is generated. More silver means more conductivity with less layers but the extra liquid can lead to smudging of the circuit.
As a rule of thumb a lower value for print_overlap mans better resolution but longer the print time. Remember that print_overlap can only be an odd integer less than 103.
Now you can align your printer!
