Understanding How Ink Density & Default Ink Limit Work

Understanding How Ink Density & Default Ink Limit Work

2011-01-27 by Terry

This is a basic question that I'm unclear about.  I have used the Forum Search feature and not come up with a clear answer.

1) If you have the PK (or MK) ink set for 75 and the default blank, does that mean the PK prints at 75% of the maximum amount of ink the printer will release?

2) If you have the PK (or MK) ink set for 75 and the Default Ink Limit at say 50, what is the amount of ink the printer lays down?

3) If you have the PK (or MK) ink set for 75 and a Second ink at 35 with the Default Ink Limit Blank, what is the total max density the printer produces?  Is it 75 + 40 = 115?

4) If you have the PK (or MK) ink set for 75 and a second ink at 40 with the Default Ink Limit at 90, what is the total max density the printer produces? 

Thanks, Terry

Terry,

The default is just that - it is used when there is no ink limit selected
for that channel

No this is per channel so you have 75 for PK and 35 for the 2nd ink.
The max density depends on the relative ink densities of the two inks.

 The max density depends on the relative ink densities of the two inks. as
per question (3). Remember the default ink limit is ignored when you set an
ink limit for a channel.

Mike,

Thanks for all of your help. 

Follow up to Q3

3) If you have the PK (or MK) ink set for 75 and a Second ink at 35 with

The max density depends on the relative ink densities of the two inks.

I'm using a R800 / R1800 standard Epson Inks and if my second ink is Blue in the above example (PK=75, Blue=40), how is the Relative Ink Density determined?

By printing targets in calibration mode. See

What are you actually trying to figure out with these questions?
Might be easier to just ask the question you are trying to answer :)

Re: Understanding How Ink Density & Default Ink Limit Work

Actually trying to understand the "logic" of the settings.  
I see QTR is basically set up for a gray second or third ink (and the relative densities make sense) and my question related to a color ink as a second ink probably doesn't make sense with QTR.

What I have been playing with is how to eliminate the greenish cast I get with printing with the PK only Epson Black ink.

Thanks, Terry

Yes you need to add a bit of magenta to the mix to eliminate the greenish
cast.
I would check out Paul Roark's work for more info on this.

I made some profiles for Claria printers some time ago.  They are now in the
QTR R260-MIS Profiles folder.  See the ones that have "N-1" in the names.
 Those are the ones that have magenta (and even yellow for the Aurora paper)
added.

Recently I've been exploring the Noritsu-Epson inks that are sold into the
photo finishing market.  They appear to be bulk Claria inks.  There are a
number of options for using them in B&W.  Some of my initial notes are at
the following URLs.

http://www.paulroark.com/BW-Info/BW-Dye.pdf

http://www.paulroark.com/BW-Info/N-BW-VT-1-220.pdf

My interests in these inks comes from their being quite superior on high
gloss media, which I think make good cards and brochures.  They also have
done remarkably well in the Aardengurg Imaging --
http://www.aardenburg-imaging.com/ -- fade tests when sprayed with Print
Shield.  I'm not a fan of these sprays, and for sure will not be spraying my
cards, but for those who want dramatic glossy B&W and just occassionally
want one that is good enough to hang on the wall long term, the sprays make
this possible.  A sprayed Claria black only print is almost as stable as an
Epson UltraChrome "ABW" print.

As a practical matter, I use the 1400 with Eboni-6 (or it's derivatives) as
my main printer.  I've found 4 positions of Eboni are all that are needed.
 So, I'm using the other 2 for other inks.  These will include the Epson
advanced dyes.  See http://www.paulroark.com/BW-Info/Eboni-4-Plus.pdf  This
PDF is a work in progress.

Hope this is useful to you.

Thanks for the comments and references...this may help especially if I get into the MIS inks.
