No, you can never have too much pink. Except when it’s in skin tones and you’re producing a wedding album for a client.
Mike (my lab printing guru) and I have been working on Sam & Tims album. Thankfully Mike is able to print a preview of 9 pages to a side double sided and jot correction notes where needed, a number of the shots were coming out a tad on the pink side and needed “Yellow +1”. The dynamic range of a printer is much much lower than that of a CRT or LCD screen so the images have to be 100% in order to look their very best. If you’d looked at many of the images on their own you’d not have seen it. When a number are printed side by side the difference becomes more apparent and needs fixing.
