Whilst it has reasonable line variation, this pen doesn’t much like to draw the fine lines all that easily.. High flow as well, perhaps more suited to the low porosity mediums – I am just using cartridge paper at the moment.
conclusion: Platinum Fude Brush Pen likes to draw BIG on SHINY PAPER.
Trying to do a doodle a day. Last night’s, based upon a small person with a penchant for pirates and princesses turned out pretty fun, so I thought I’d have a play with this digital colouring malarkey.
Original with Waterman fountain pen and Noodler’s Bulletproof Black.
Two versions, digitally coloured and with paper backgrounds I scrounged from the intertubes.
I used a new plugin for creating the ink overlay for colouring under which is pretty handy, I mean you can desaturate, set to multiply and adjust the opacity – or just apply this filter – it’s free and you can get it here
The final inked version (with drawing inks). Delivered with laserjet copies of the line drawing for personalised colouring in funs. The exciting string on the packaging was a BIG HIT.
Apparently this is not something I should do with my new ink; Noodler’s Burma Road Brown. 
Personally, I think brown is a perfectly respectable ink colour, and more importantly, it is an awesome colour for sketching..
A perfect time to try out my newly enbladderated vintage Waterman lever fill I obtained in a job lot on the ebat. I managed to remove the old ossified bladder without too much incident and replaced it with a new one from www.penmuseum.co.uk. Luckily, I did not yet shellac in the new bladder, as it splurted a big blob on my ferret’s foot as I was doodling him (I think this might be because the bladder was too near the pen walls, and was warmed by my hand – I could be entirely wrong..).
I might try diluting it slightly, to see if I can get some better colour graduation – and it does seem a little prone to clogging slightly if I am using light strokes.
I also have the Noodler’s bulletproof black – the main point behind these two ink purchases is their relative water resistance, for ink and wash painting. Dip pen ink contains shellac, which is death to fountain pens, hence permanence in fountain pen ink is not by standard, very good.
