Sanzen Tomoe River behaving differently on each side of the sheet

[Harold]

Have any of you tried Sanzen's Tomoe River and found that the colour reproduction is completely different between the front and the back of the paper? I was just writing on it with Pilot Iroshizuku Syo-ro & Ku-jaku, and I noticed that both inks look much greener on the backside of the paper than the front. It's so bad that when I compare the back of the page written with Ku-jaku to the front of the page written with Syo-ro, I have to look at the slight difference in saturation to be able to tell the two inks apart. Then when I compare the front of the page written with Ku-jaku to the back of the page written with Syo-ro, they are literally a complete shade(30 degrees on the colour wheel) apart.

 

Comparing Tomoegawa's old TR(or something similarly ink resistant like Kobeha's Graphilo) to Sanzen's TR, the colour reproduction of the old paper seems very close to the front side of the Sanzen paper. The back of Sanzen's paper is much more in line with pretty much any other decent-but-not-godly paper I own, like Rhodia or Kokuyo Sarasara. It really seems like the back of Sanzen's paper is more absorbent than the front. It really looks like some wild inconsistency in the sizing or calendering of the paper that is allowing more of the yellow paper colour to show through the ink on the back.

You could be looking at a batch of machine 9 or 10 TR paper. When Sanzen made the deal, they took all the stock. I read there were problems when they moved TR from the num. 7 machine .

It is common for recto and verso sides of a sheet to have different characteristiscs

A good thought, but I'm 100% sure it's the new Sanzen-produced stuff.

Definitely; it's one of the many reasons I don't use Rhodia. I have not seen this much of a difference in any paper I've ever used though. It's the kind of colour shift you observe when viewing the same ink under yellow incandescent lighting versus bright white daylight. I can only conclude that I will be looking for a new notebook paper if this isn't just an issue with early batches of a new product they're still learning the ins and outs of.

Yep. Rhodia! Does not only look different, it feels different to write on as well. Clairefountaine Triomphe is also afflicted by this. I think most papers will be. Please share if you come across any paper that does not have the 

Karmachanic  effect 😀
