Improvements in system or ornamental engraved on marble and Onyx.

摘要

The present Invention relates to improvements in or ornamental engraving procedure called marble and Onyx steps consisting in: (a) in the plate to print to record,Methods the silkscreen or Flexographic desired drawing,With a Lacquer or Polymer that is not strongly attacked by the acid used in the Etching process and whose adhesiveness after undergoing the procedure of acid Attack and neutrali SolutionZakynthos is lower than the hardness of the plate; (b) to submit the Printed surface of the Printing Plate, when Polymerized,A bathroom with an aqueous solution of an Acid selected from nitric acid, hydrofluoric acid or hydrochloric acid for 15 to 20 minutes.(c) washing The plates with an aqueous solution of Sodium bisulfite To Neutralize and eliminate the residual acid when the etch depth is appropriate.(d) Drying The plates and brush to remove the waste Polymer or Lacquer.
