We are having trouble understanding really what we should pick. Based on what we have heard, and based on our understanding, passes only control the speed of the print and saturation controls our ink usage? How does that work? 'Cause wouldn't it put down more ink with more passes?

We are just having trouble understanding how exactly the ink system works.

Hello @ICF_Printer1

Let me clarify how the ink system works in terms of spitting:

The more passes you use the better quality will result since the ink density per pass is less and therefore it avoids coalescence. Therefore, you will always get the same ink density set in the Print Mode, no matter how many passes you set.

Hope it clarifies

#1 Saturation solely deals with the amount of ink for a given colour value. This is proportional to the amount of ink used.

Print passes solely deals with the rate and accuracy of ink being placed onto the media/substrate. Due to the amount of ink being used it is very difficult to use high amounts of ink on a low pass because it needs time to dry and settle correctly. You can do the exact same image with different passes and the ink usage would not be adversely different. The quality of the print is improved due to better ink droplet placement when using higher passes. Your only truly measurable factor is time. Quality could be considered purely subjective.

You should always do some test prints to determine the best quality with ink usage.

Accuracy/Quality - High Pass Deeper colours/Higher Saturation/Backlit - High Pass Fast print - Low Pass Low quality - Low Pass
