In the Rotogravure section 3 of this process, After the cylindrical tube had completely coated copper layer, then the next is done sanding on each cylindrical tube which is newly coated copper. This was done so that the cylindrical surface to be flat and clean.
In the process of sanding / smoothing this an indispensable motor armature. The point is as a player tubes will be smoothed. do sanding the cylindrical, cylindrical tube which is sanded in a state of the tube continues to rotate, so that the resulting tube is really uneven. Keep in mind,
Well, after the refinement stage, it is time to clean the cylindrical tube and perform the next stage. ie move the results of the desired image. In the Sablon, it is also called by the name Afdruct.
This process is greatly needed at once a special clean room. Because some dirt / dust will greatly affect the results
1. First, clean the tube as clean as possible
2 apply emulsion / TPR evenly on the tube
3. after completely dry, then do the attachment / transfer images from the media mica film as desired.
At this stage of this process, paste images that you use, check first, then do radiation with a gunshot fired lamp, irradiation time, the cylindrical should still spinning, so the lighting to be flat.

COPPER ROTOGRAVURE CLYINDER
It's time I try to connect the topic article yesterday about the Copper Rotogravure / Coating.
The equipment needed for the coating process of the iron coated copper tubes, among others.
- A transformer that serves as a shock that would attach the copper tube to be coated iron roll.
- Body made of materials resistant to chemicals and strong weight-bearing terandung water in it, so it will not happen to leak or rupture tub, while the tub filled with water on a lot of volume. Water reservoirs amounts to 2 (two). A second later the tub filled with water that has mixed several different chemicals between tub 1 and tub 2
The first tub has a size of approximately 1 meter long, 2.5 meters wide with a depth of approximately 50 to 60 cm. and for a second bath having the same size but different length, which is about 2.5 to 3 meters
- Materials Chemistry, an important function in this coating process.
- Dinamo motor serves to rotate the cylindrical tube to be coated copper
Immediately, I try to discuss this coating process
1. Fill water tank with water (Must use tap water) because if you use ground water, will be a negative impact on the outcome of copper.
In a tub, mix water with chemicals and POTASSIUM COPPER Cyanide
In the tub 2, mix water with chemicals and copper sulfate and acid sulfate / H2SO4
Stir until evenly distributed, so each tub with a flat dissolved. Please keep in mind. between tub 1 and tub 2 content should not be mixed although only slightly,
After mixing these chemicals, then put the tubes to be coated and which have been cleaned. first dip tubes in bath 1 (the first), in a matter of time. after that when benar2 evenly, move the tubes are immersed in the bath tub 1 to 2.
Now in this second bath is a chemical coating process occurs, in addition to water containing these chemicals, like these two that will be hung lempengan2 copper plate will be eroded by itself and will be attached to move against the tabung2 iron, we can see it on video I attach before. Remember, this is done by running the motor armature which rotates continue tabung2 and provide the resulting shock process is carried out until the transformer would benar2 iron copper tube has been coated with sufficient thickness and not too thin, copper process could take a long time , approximately between 6-7 hours, depending on the strength of shock produced by the transformer and the approximate thickness of the layers as desired.
and for that I will try to discuss it further at the next opportunity.

Rotogravure cylinder manufacturing process
On the chance this time, I try to describe the process of making cylindrical tubes rotogravure. Perhaps what I write and I lay still many shortcomings and lack of details of what I write this, given in the process of making this tube I do not really at it and just knew it. I hope that can be tolerated before.
1. TUBE cylindrical PRINT
In this case, the tube that will be in gravure must have a diameter corresponding to the length that would be conducted the piece in a plastic roll. It is very important, especially when color printing consists of more than 1 (one) color. Between the cylindrical one and so should be the same diameter, must not be less or more because it is very hamper.
first of all, puree the surface of the cylindrical tube, prior to immersion copper coating on the tubes. After completely flattened tube is then ready to be copper / copper coating.
2. COPPER / coating
In this case, it takes some equipment needed to perform this process, as I will provide a video picture. and henceforth I will discuss at another occasion.
