Portuguese term or phrase: Controle de Solução de Molha

Hello again,

Still the lithography process.
The term I'm not sure now is "molha" and the sentence is "Controle de Solução de Molha".

Thanks again!

Best,

Sabrina Sattnin

English translation:Fountain Solution Control

Explanation:
https://en.wikipedia.org/wiki/Offset_printing

Fountain solution is the water-based (or "aqueous") component in the lithographic process that moistens the non image area of the plate in order to keep ink from depositing (and thus printing). Historically, fountain solutions were acid-based and made with gum arabic, chromates or phosphates, and magnesium nitrate. Alcohol is added to the water to lower the surface tension and help cool the press a bit so the ink stays stable so it can set and dry fast. While the acid fountain solution has improved in the last several decades, neutral and alkaline fountain solutions have also been developed. Both of these chemistries rely heavily on surfactants–emulsifiers and phosphates and/or silicates to provide adequate cleaning and desensitizing, respectively. Since about 2000, alkaline-based fountain solutions have become less common due to the inherent health hazards of high pH and the objectionable odor of the necessary microbiological additives.

Example sentence(s):

These problems are most often expressed in disturbing the optimal balance of wetting solution and printing ink during the printing process and in appearance of
The increase in the surface free energy and causes an increase in the wetting solution for wetting.
