I have put a fair amount of HP Matte litho realistic paper through my z3100 in the 2 years I've owned it and it is a favorite paper of mine. Recently a client brought in some prints I'd done for her about 18 months ago along with some more recent ones - she had noticed that the page white on the early ones was noticably yellower than the recent ones. A rummage through piles of test prints in my studio showed a considerable variation in colour. Her prints have been kept in a portfolio interleaved with acid free tissue so not yellowed by exposure to light - in any case, this paper is supposed to have archival qualities so shouldn't have yellowed in that timescale anyway. Has anyone noticed yellowing in this paper or a noticable colour difference batch to batch?
With the yellowing of Epson Enhanced Matte in mind I planned to purchase HP Matte Litho instead. It is a more natural white so I assumed less OBA aboard. Woodfree which doesn't make it archival yet. Heavier than EEM and with a lower price than EEM over here. The only flaw being the smaller maximum width = 36". If it yellows at a slower rate than EEM it still will be a good choice for me, it shouldn't compete with the Photorag etc papers. As I understand it it is a good proofing paper for the last.
