VS-540 Greys printing Pink

[TurboGraphics77]

im new to the printing world, have printed some things and come out perfect, scratching my head as to if im saving files wrong or im doing something wrong, use cmyk?

depending on what im printing, some things that have any grey or shadows of grey print pink or shades of pink, print head tests are good, perfect prints no missing nozzles
i have manually decreased magenta in versa works it makes it better, i print on signs and display

very frustrated hope to get some answers thanks

get an xrite I1 or similar spectro & start building profiles for your commonly used materials

Grays are the most difficult colors to print using CMYK. It is normal to have them tend toward pink when they are warm toned. Best thing to do is print a bunch of grays and save in Flexi (or whatever design program you use) the ones that you know print well. Understand that to build the gray color the RIP software uses a percentage of each CMYK. While you expect it to use black for blacks and for grays, it does not - as low as 10% Magenta will make a gray pink. Hope that helps you
