The production process of printmaking

The steps of the production process of printmaking are as follows:

1, drawing. There should be a complete consideration of the composition of the picture, modeling, black and white and gray relationship and knife organization in the drawing. In the initial small draft, there should be a basic consideration of the language and final effect of the picture, as well as the production process, but the draft does not need to draw every detail specifically, and should be randomly processed according to the overall conception of the creation and the generation of the picture relationship.

2. Prepare the plate. Plates need to be polished and hardened before engraving. Hardwood plates can be used for engraving after fine sandpaper polishing, for the wood is soft, the surface of the plate has a dent still have to scrape filler putty leveling, and make the plate hardened. Before the transfer to the surface of the plate should be painted a layer of color, so that the engraving can clearly see the relationship between the picture.

3. transfer. One method is to cover the sulfuric acid paper on the drawing in advance, with a pencil will be the main outline of the figure and the basic direction of the line sketched down; copy paper turned over on the page, in which the clip into the duplicating paper, and then copy the line draft to the page. Another is to use the copier to copy down the black and white drawings, flip face down on the layout, surrounded by tape paper fixed, take a small piece of cotton cloth dipped in banana water on the back of the copy paper rubbing, so that the carbon on the copy paper dissolved away from the transfer to the layout.

4. engraving. The engraving method of woodcut prints is the opposite of the general directness of the painting, is constantly reduced from the layout, the picture engraving is irreversible. Woodcut printmaking is the use of a variety of knife shape produced by different knife touch to shape the form, "knife instead of pen", "put the knife straight dry".

5. Ink. After the plate engraving is completed, with a cotton cloth or brush to remove the plate debris, you can apply ink test printing. First, the ink will be taken out, with the ink spatula to repeatedly adjust the pressure, and test its fluidity. Ink spatula will be ink spread on the ink mixing platform, and then roll back and forth with the rubber roller, until the ink platform and the rubber roller are covered with a thin and uniform layer of ink; and then use the rubber roller to roll over the printing plate repeatedly until the layout of the ink is uniform.

6. Revision. After the first proof printed, against the sample for plate repair. Revision should be adjusted according to the overall relationship between the picture, printmaking is subtractive, the place where the error should be adjusted through the corresponding relationship between the picture. Repair completed can be formally printed, printed works hung to dry before storage.
