Ink Order

[benb]

Hi,
In a one pass thermal inkjet printing system, if we have 5 or 6 inks, (e..g CMYKGrR), what is the best ink order to increase gamut size and some other print artifects such as black on yellow dots? Does anyone know what HP Indigo does?

Now if there is around x miliseconds (e.g. 500 miliseconds) delay betweeen laying down the color, e.g. 500 milisecond delay between putting the first color channel and second color channel, should we worry about any artifects beside coalescence?


thank you for your input
