Asunto: Re: Deposit on glass for framed photo

I let them dry a few days, then dry 4 minutes under ethers). The solvents act to slowly fuze the resin binder together after the water has evaporated from the ink. This is why it takes time - several days - for the printed surface to gain water and mar resistant properties. (prints on RC photo papers straight out or the printer are quite easily scratched, and although they have some water resistance, after a day or so drying they are much more resistant - effectively water proof) These solvents take days to evaporate. If the print is framed before they have evaporated fully, then they can condense of the glass surface. The solution is to allow a reasonable time (perhaps a week) after printing before framing behind glass. Debes registrarte antes de enviar mensajes.
