I seriously doubt it. I've been using it in parallel with
Multigrade IV glossy fiber and it is different in the following
ways:
Paper:
The curl characteristics and feel are different. Perfecta feels
heavier (in fact you will probably mistake the protective
cardboard for the first sheet). Which has the better feel is a
matter of personal taste. Perfecta feels like the Kodak papers
from 30 years ago.
Surface texture:
The Ilford has a coarser chain pattern.
Surface reflectance:
The Ilford emulsion isn't as "wet". But the Ilford geletin
appears to microcrack a little nicer.
Maximum Blackness:
The Perfecta paper reaches a blacker black.
Exposures:
Depending on grade, it's up to 1/2 stop different speed.
Grades:
Depending on negative base color and enlarger light source
you'll see about 1/2 grade apparant grade increase with the
Perfecta paper with little affect on mid and high values.
Color temperature:
Multigrade IV Fiber paper tends to yellow more while the silver
tends to have a purple cast. Perfecta paper is more neutral and
the silver doesn't have the purple cast.
Sensitivity to color filtration:
Multigrade is very forgiving to color/grade changes. Perfecta is
much pickier. I cannot use the color head dichromatic controls
with Perfecta but must use Ilford graded filters.
The stuff *might* be made in the same factory, but it is
definitely not the same stuff. I'd take those comments with a
grain of silver salt.
By the way, Multigrade IV papers develop MUCH better in the
Perfecta-D developer and lose nearly all of the purple cast and
achieve a denser max-black. But, it's still different than the
Perfecta in all of the above manners.
