Default Ilfochrome Re-Deux, Part 2

Those of you who have responded to my printing problem, I thank you, and I
took your advise. However, nothing has changed. I have persistent and
extremely long printing times with this material - up to 140 seconds, and I
cannot believe that this is "normal". I'm using the Beseler 45 Universal
Light Source - 4x5 diffusion, and a Nikon N2.8 enlarger lense for 35mm work,
enlarging to 8x10 with this paper.

Processing is standard at 30 degrees for the Ilfobrom process, done on a
Jobo CPP/Lift, using Ilfochrome chemestry - always fresh chemestry.

The resulting print is characterized by a dark, dense image. There is a
slight shift toward magenta. At 140 seconds exposure, the image finally
begins to look normal. However, with these long exposures, I've had to make
5 exposures at 20 seconds each to avoid overheading the Beseler or buckling
of the slide - non-glass carrier.

I've asked before if this is normal, and I'm asking again: Are those
printing times within what is considered "normal" for this process - I
understand that the paper is 'slow'.

Tanks again!!

Some dumb questions:

o Does the Universal head come with a 35mm mixing chamber?
I have the impression it doesn't, but is there some adjustment
or insert for 35mm work? Manual say anything?
o What is the head-negative height set to? [adjustment
normally used with the condenser head, scale on the right
o Does this combination print OK when used with B&W materials?

Have you contacted Ilford?

BTW sometimes the answer is just "I don't know" and rather than getting
150 responses with "I don't know" the group just remains silent.

But here goes: I used a medium format Durst Enlarger with a 35mm mixing
box when printing Cibachrome (see long time ago). My times were quite
long as I recall, details vague, it was 30 years ago. Slides never
buckled. So I guess I don't know.

No, your printing times are way too long. It doesn't
matter how many times you ask. The answer will
be the same. When I print Ilfochrome my printing
times are on the order of 20 seconds. These are the
same as my black and white printing times.

What is "Ilfobrom process", by the way? The chemistry
I use says P3 on the box.

Ilforchrome is really easy to use, and really easy to get
right. Whatever the problem is, it doesn't sound like USENET
can do anything about it. Do you have anybody local
who can help you?.

No, it is not normal.
My times are around 3 stops longer than Ilford Multigrade IV paper
without filter which is around 20-40 seconds at f/8 for a 30x40cm (12x16").

Chemistry is either P-30 (no more made), P3.5 (5 liters, all liquid,
replaces P-30), P-3 (larger quantities) or P3.X (large quantities,
replenished).

Note that the contrast of Ilfochrome paper is much lower than B/W or
RA-4 negative paper as slides are very contrasty and though paper must
be very soft to restore a normal contrast (but global slide+paper
contrast may be too high).
This means that when you adjust an exposure, you must use larger values
than thos common in B/W: a half stop in B/W is a big difference, with
Ilfochrome you easily change it by full stop values and when you're in
the 40" range, a full stop more exposure is another 40" ...

To avoid to overheat the film/slide, you should put a hot mirror filter
between the enlarger's lamp and filters.
You can buy such filters at a reasonable price at B&H
(www.bhphotovideo.com), search with "Rosco hot mirror"
For those wanting to replace their dichroïc filters, they also sell MCY
or RGB filters.

Good luck,

I do remember having similar long times with Ilfochromes perhaps 15
years ago. Part of it was due to the fact that I did not have the 35mm
mixing chamber for my Beseler 45. That would have cut the times at
least in half or perhaps even more. I only experienced this with 35mm
slides. When I began using medium format exclusively, my times got
shorter. I suspect that's a good part of your problem.
