Do you want to know what happened after washing one of the lithograph prints??

So here you are, the before and after washing treatment where you can see that the foxing spots have disappeared completely over the paper surface.

As we said before, the foxing reddish-brown spots can appear in the paper surface due to different causes. For example, the print has been exposed to relative humidity and temperature fluctuations for a long period of time creating an environment for the growing of mould or another possibility, could be that during the paper making process were used raw materials infested with mould.

These micro-organisms can remain latent for months or years awaiting for the appropriate conditions for growth and there are a wide range of colour stains. In some of the lithograph prints we found basically small yellow spots in different areas of the paper surface.
