Technique of printing on stone matrix - Flash animation

Printing from stone matrix is much quicker than in case of convex and concave printing techniques. Rolling up the stone before making each print takes only few minutes.

Before we start printing we have to prepare paper for the edition, paper for proof prints, we have to mark registration marks. We need to prepare bowls full of clean cold water, a sponge to wet the stone during rolling up the stone, and almost dry sponge to absorb water redundancy.

You have to set up the stone at the end of the press table. Without moving down the handle, move the table with the stone to the scraper (to the exact place where the scraper is over the stone but in front of the drawing). The optimal position is where the scraper is in front of the paper. You have to mark this place on the immobile press part in order to pass the table to the same place each time. Next, move the table to the end (without moving the handle down) and check if in this position the scraper is already besides the drawing and over the stone (the optimal position is when it is besides the paper).

On the rolled up, dried stone (dry the stone because otherwise the paper will change shape under the influence of water) you can put paper for the first proof print. The stone gains the perfect blackening after several proof prints. After putting the paper on the stone you need to cover it with one more sheet of paper to give more isolation between paper, tympan sheet and scraper. At the end you need to put lubricated tympan sheet, for the scraper to be able to slide on it during the press ride.

Now you can start printing. Move the table to the marked place. Check the pressure. Lower the handle. If you do not feel resistance it means the pressure is too weak. If you are not able to lower the handle it means that the pressure is too strong. The knob over the scraper lets you set up proper pressure. Now you can ride the press table to the end with the steady movement. If the scraper stops during the ride, there is possibility that you will achieve a stripe on your print. When you finish the ride, raise the handle, move the table to the starting position, take the tympan sheet off, take the interleaving paper off and raise the print very gently. Put the print on the drier, wet the stone immediately. The stone should be wet during all the time f the process of printing (except the very moment when you put the paper on the stone).
