Etching Rotogravure

etching Process
Rotogravure Process Continuing on the topic before, after the cylindrical tube in afdruct. Lift and move the cylindrical tube on the room lighting. Clean the cylindrical tube that has been in afdruk earlier.
Before watering, first, apply a cylindrical part that is not about the image of black mold with liquid asphalt. It is very important, because its function to prevent dirt rub off on the process of attachment earlier. so when watering later then the result is just the image we want only scratches arising form pores.
Once the cylindrical tube is greased / oiled liquid asphalt and dries, flush cylindrical tube that has formed a desired image by using ferrid chloride solution. Sprinkle evenly cylindrical tubes, copper tubes until they form / arise pores of the desired image. This process is also called Etching.
and this is the end of the Rotogravure process. And the cylindrical tube is ready for use, I hope this can help as an input for those who want to know the process of making plastic molding selinter, I admit there are many shortcomings in this paper. I hope that is understandable.
