I have been trying to find Australian supplies of paper that are fountain-pen happy. It has been difficult. What I have found falls into several categories -
1. Cheap Asian Pad Paper
Usually found in `Warehouse' type stores that get their product from S.E. Asia. This paper is thin, 50-55 gsm, and varies from smooth to rough. It generally takes FP ink reasonably well, but as it tends to bleed through, you can only write on one side. The brands available tend to vary from month to month, so if you find a stock you like, buy LOTS of it.
2. Fluoro Chinese Pad Paper
This is 80 gsm Fluoro paper that is sold by Officeworks and Big W. It used to be made in Australia and New Zealand, but recent stocks come from China. The Chinese product is smoother, more pleasant to write on, and comes in more vivid (some would say violent) colours than the locally made stock.
The rougher Australian stock is good for breaking in a cheap Chinese nib.
3. English Pukka Pad stock
This is a range of 80 gsm Notebooks in various sizes from A6 up to A4. The paper is smooth, and a pleasure to write on with almost any pen. Some inks, like Parker Quink Blue-Black and Private Reserve Lake Placid Blue will bleed through. Others, including Parker Quink Permanent Blue and Sheaffer Skrip Blue-Black, don't. Those inks that bleed show a touch of feathering, while those that don't bleed don't feather.
4. Copy Paper
You can make your own stationery by using copy paper. You can print lines on it and bind it into pads or notebooks. I have tried a number of different products, both ordinary and premium, and have settled on two.
The first is HP Everyday Paper. It takes ink nicely, and has a lightly textured (but not quite rough) surface. This means that while it is reasonably smooth with most pens, it will `start' your more reluctant pens.
The other is HP Colour Laser Paper, which may be known in the US as HP Premium Choice LaserJet Paper. It is a 120 gsm paper, very dense and very smooth. It is a delight to write on, but it is so smooth that some pens may not `start' on it.
5. Visual Art Diary
I started using a Windsor & Newton Visual Diary to keep colour swatches of inks. Its acid-free makeup meant that the paper would not contribute to any colour change in the inks. However, it is much too rough to write on for ordinary purposes. But, with the beginning of the new school year, all sorts of new products are appearing. I found two which are excellent to write on.
The first is a Quill brand A4 Visual Art Diary, 110 gsm acid-free cartridge paper. This is distributed through newsagents. I found mine at a Newspower newsagency.
The second is a Hunter Studio A4 Visual Art Diary with 100 gsm acid-free paper. This one is a little smoother than the Quill product, and nicer to write on. I found mine in my local `Warehouse' store, in amongst the `Back to School' supplies.
Of course, there are other paper products available in Australia. The ones mentioned here are just the ones I have found and been able to test. The Tudor brand products all seem to be made here, and people have said they work well.
inkypete mentioned kikki.K. They currently are running a New Years Sale. Worth checking out if you're in oz.
