When is paper paper, not when its kodak paper........

I just found an older pack, it works a treat!

I did the usual clean board, wipe with a dilute etchant to take the
shine off and leave salmon pink (I'm on ferric from maplins uk) then
iron on for about 3 mins etc, drop into cold water.


When you come to take it out the water it peels off with a loud
creaking noise as the toner splits from the glossy backing.

This leaves a toner only coating on the board as opposed to toner and gloss.

This paper is ''kodak inkjet photo paper' 190gm2 cat 178 3547,
kp105417, 38302 41, 04fkc7 17, I dont know which number is specific
to it but its a 50 sheet pack

The one that makes really proud toner and gloss fibre tracks is
'kod-aper glossy inkjet paper' 180gm2 thickness 0.21mm but has no cat
number or barcode or anything and is 25 sheets in a (shrink)wrap

In fact I think its a fake paper, made to look like kodak etc, looks
like I may have been duped I thought I was buying kodak!
