The inklimit for inkjet printers is very low - typically 240-280 %.  
It means the printer may drop only such amount of particular inks  
that they sum is not bigger than inklimit. If more, the ink will stay  
on surface of paper, flow, etc.

So it is very important if it will print the 100 % C + 100 % M + 80 %  
Y or 40 % C + 40 % Y + 20 % Y + 60 % K to print the same shadow. In  
first case the amount of ink is 280 %, in second 160 %. In the second  
case you may add 40 % black for deeper shadow. The real world  
printing is not so simple but as an explanation it is enough I hope.
