Gentlemen and fellowLithograpers,

With great respect for Mr. Dan. Remaley also Felix Brunner and their many articles about "Grey Balance"

I suggest you read Gordos PrintBlog article entitled "Grey Balance Unbalanced-An inconvenient truth"


Regards, Alois
 
Here's an item I wrote several years ago and the responses.
The standard deviation of a press is + or - 2%. That 4% variance in any particular color will show a cast but if you keep the colors in 'balance' the 4% variance becomes only a 'light' or 'dark' variance - this difference we can live with. (see PCReference).
Here's an idea I always wanted to try- take your 50-40-40 patch into Photoshop and set for Medium GCR - these new values can be placed in the color bar. Now the grey patch won't "change" until the standard deviation happens (+/- 2%)... Of course you need to apply same amount of GCR to the images & tint builds at rip level.
Attached is a pic of the ALL color readings on a X-rite 530. When the C-M-Y is within .03 of each other = Grey.
Certainly none of this matters printing a Red fire Truck or saturated pictures. . .but it won't hurt them either! I don't buy the "in line" argument - the separations have the correct size dots for a 'correctly' printed sheet - if not - go back to pre-press and adjust the dot size! You can't "color correct" at press you can only color ruin!!
I managed a color trade house in Pittsburgh making separations/proofs for printers.
All the best!
