I purchased the Deluxe PiezoDN Ink, cartridge, and flushing system and need assistance to determine cart positions for Photo Black and Matte Black.
The kit arrived with two Shade 1 inks: Neutral Shade 1 (PZK7-NU-110-1) & Warm Neutral Shade 1 (PZK7-WN-110-1) - which one goes into the Photo black slot? Neither bottle indicates Photo or Matte
