QTR-Quadtone RIP

Hey Dileepa, I've found that with glossy paper (my only experience so far is with ILFord 
Gold Fibre Silk IGFS) that I did get higher dmax with the LM and LC inks than the M and C 
inks on the glossy; dmax of over 2.30 with the LM.  The Eboni M ink shouldn't be used 
with glossy unless you are trying for a 100% carbon print on glossy that is somewhat more 
neutral than the warm inks in the M and LM positions; and only with a generous dose of 
glop and then a couple coats of Premier Print Shied after it dries overnight; you got my 
profile for that.

Be sure to take readings for less than the 100% patch as many of the inks once it reaches 
it's dmax at a particular ink limit starts to decline with a heavier ink load.  Also you will 
notice that many of the inks will have a significantly higher dmax after a spray of the print 
shield; see by taking a reading before the spray and then after; doesn't seem to effect 
tones much other than the very dark ones, which is good.

By the way the print that has impressed me the most so far has been on the IGFS 100% 
Carbon with the Eboni and glop and the Print Shield.  I know it's warmer than I'd like and 
grainy looking and I hate having to spray, but this has produced what I consider the 
"richest" looking print yet with the system, achieving a dmax of over 2.50 on IGFS, 
primarily due to the spray of Print Shield.  Also, the shadows have much better separation 
and more detail.

Next week or so I'm going to be experimenting with replacing the cool PK and LK in the C 
and LC positions with HP PK in the C position and a dilute of HP PK with glop in the LC 
positions; see post on the Digital B&W forum, subject: HP PK BO.  i'm going to be testing 
using Cranes Mueso Silver Rag, as Paul Roark has reported geting a dmax in the 2.60's 
and close to 2.70 using with the HP PK and Silver Rag.  I haven't been impressed with the 
shadows using the cool PK inks from the UT-14 on glossy and hoping this change will be 
a positive one.  

If the HP PK doesn't work I will probably go back to the profile using the Eboni and glop 
and spray; I would probably experiment with using a more dilute Eboni for the midtones 
and highlights to try to reduce the graininess and smooth out the tones a bit.

God, I'm tired of all of this experimenting and am looking forward to settling on a 
workflow soon and getting back to the more serious work of working on my portfolio.

Hope this helps,
Randy
