Digital BW, The Print

Alpha is OBA free.  Delta has some OBAs.  Omega, I thought, has some, but
under a black light (not the best one in the world) there seems to be very
little if any in it.  

Omega has a dmax of 1.67.  Each batch of paper seems to vary a bit, but all
three of the new PermaJet papers are consistently between PhotoRag (1.71)
and EEM (1.64-5), which is excellent.

Subject: [Digital BW] Re: Permajet Alpha, Omega?

I've recently started using both - limited to A4 size so far - with 
my 2100 and UT7 inks.  They're both 310 gsm, they're both slightly 
smoother than Photorag.  The Omega is very slightly whiter than 
Photorag whilst the Alpha is a very pale cream.  To me they're 
identical but for the colour difference.

I like them both and plan to use them along with Photorag - 
particularly for sales.  DMax seems excellent to my eye, but that's 
the only measuring equipment I've got.

I've seen somewhere in this group a reference that they (or at last 
the Alpha) don't use optical brighteners, although you'd have to 
check that for yourself.  So presumably no flaking - although I've 
never experienced that with Photorag.  As for permanence - who 
knows.  But as 100% cotton rag they should be (?) up there with the 
best.
