Magenta cast when printing A4

[spriggyy]

Hi all

I use an Epson RX500 printer.
The printer provides excellent colour prints at 6x4 but when I print the same pic at A4 there is a definate magenta cast.
The screen pic is perfect and any 6x4 print, any ideas?

Regards

I think it's not too unusual to have color casts show up like that as you print larger. I had the same thing happen when printing A3+ sized prints--they had a magenta cast that I hadn't noticed at smaller sizes or on screen. My solution was simply to go back to the RAW development and change the WB color adjustments slightly more to the green side.
