We need a technician to inspect and fix an issue with two UV printers using Ricoh G6 printheads. The problem is poor CMYK color alignment, with blue, red, and green edges appearing around the artwork, as well as misalignment of the white layer. We have already adjusted Color Offset, Y Offset, and R1/ R2, but the issue remains. We need the printheads, tilt, alignment, bi - direction settings
