Hello all,
I'm printing with a gr3770 since last year and everything is great but the problem of the never-dried inks, wich is somewhat inherent of the process. It didn't really matter until now, because I've got two new books to print, including their covers and I'd like to avoid sending books that make stains all over the client's hands... I know I'm not the only one with the problem (http://www.copytechnet.com/forums/sh...3750-Risograph), so I'd like to find a technique to resolve it (other than putting a plastic sheet on the cover).
I tried several papers (Munken Print, Munken Lynx, Multidesign), some are better than others but the problem remains.
I was thinking maybe to accelerate the drying process by making a drier with a small electric heater and some pc fans. Do you think that blowing hot air on the prints could make it?
Also, I know that in silkscreen printing, one can use products that, mixed with the inks, accelerate the drying process. It seems a little difficult and maybe not very safe for the riso but maybe injecting a little bit of this product inside the toner cartridge would work... And there is still the solution of spraying fixative on the prints but I'd like to avoid that if possible (not very healthy to empty a bottle of fixative indoor without proper aeration).
Thanks in advance for any thought!
