Epson 2000P Hex or Quad MIS Inkset ?

2017-08-13 by a_pettit_jr@...

I believe I was correct in reading an article on Paul Roark's website about using a quad set in the 2000P

The replacement was

K Black

C DarkGrey

M DarkGrey

LC MedGrey

LM MedGrey

Y LightGrey

From studying a CMYK print-ready image it would seem to me that

C and LC should be DarkGrey and

M and LM should be MedGrey ..

Comments ?

Thanks !

I'd have the dark grays in M and C. With no Photoshop curves or separate rip (QTR), the Epson driver is going to start at the light end with Y, LM and LC. As you get in to dark shadows, the LC and LM will cross over to C and M, which should be appropriately darker.

In a color inkset the Y is high gamut but low density. You can usually profile a fairly wide range of densities there. Light gray will obviously give the smoothest highlights, but not much Y is used in the highlights, so you can get away with a medium density ink there.

Good luck.

Hello Paul,

I am trying to remember what I did .. 15+ years ago.

When I apply the MIS FS .acv profiles, I transform the BW into a KCMY

color file .. It is obvious the C and M equate to quite different darkness levels - I just am not able to understand were the LC and LM fit in a hex set.

Should I try a mix based on your 3880 formula

LM = 6% MK (Eb6-LM)16

M = 18% MK (Eb6-M)

LC = 9% MK (Eb6-LC)

C = 30% MK (Eb6-C)

LK = 18% MK (Eb6-M)

LLK = 6% MK (Eb6-LM)

K = 100% MK (Eb6-K)

using perhaps

K = 100

C = 30

M = 18

LC & LM = 9 ?

Y = 6 ?

I don't remember the old 2000P Hex dilution ratios.

The 2000p is a fairly standard 6 ink printer, as I recall. As such, the 3880 formula, dropping the LK and LLK, of course, should work. A very normal dilution step between a dark ink and a lighter ink is: light ink = 30% dark ink + 70% dilution base. Having the light ink be 33.3% (1/3) the density of the darker ink is close enough and works very well. The Y is flexible. It's a great place for a light blue toner to cool the warm (yellowish) carbon, or it can be a repeat of one of the light carbon positions if you want 100% carbon.
