As you’ve already talked, there are many types of different marks. Jimmy Levin wanted to know more. One exists in particular that it has more than 200 years old and undoubtedly has been witness to many changes in technology in printing systems. Marking to which I refer is the marking of lithography. The lithographic manual technique consists of the adhesion of inks of oily and resinous consistency on paper which seeks to reproduce the drawing. This accession is what precisely causes a metallic SOAP which cannot be dissolved and that represents the base of printing signals to perform. Although this type of marking arose in the year 1796, and was created by Aloys Senefelder was until 1835 when the lithographic marking managed its reproduction in colors, what was called chromolithography. Currently lithography is used both to obtain as plead artistic works and as required, various shades of inks for reproduction are produced. With these inks, you get a final record to starting from a cross of registration on each color paper. The technique used in lithographic marking, is based on the diversion of substances both hydrophilic and hydrophobic, i.e., substances used water either to accept or reject these inks. A.
