Rotogravure Process Continued

Rotogravure Process
  Once the tube is coated with a layer of copper cylinder, then sanding is then performed on each tube of new copper-coated cylinder. This is done so that the cylindrical surface will be flat and clean.

In the process of sanding / smoothing is a dynamo motor is required. The point is that the tube will be crushed. do sanding tubes, cylinders cylindrical tube sanded in the state continues to rotate, so that the resulting tube is really uneven.


Well, after the tube was evenly it is time to clean the cylinder tube and resumed at a later stage. ie move the desired image. In the Sablon, it is also called by the name Afdruct.

This process required a clean and sterile space of the dust. Because some dirt / dust will greatly affect the results

1. First, clean the tube as clean as possible

2. Grease a tube with emulsion, in which the TPR Rotogravure
3. after it is completely dry, then do the attachment / transfer images from the film mica media as desired.

At this stage of this process, do radiation on the picture tube that has been affixed with the state of the tube rotates, so that radiation can be performed equally
