Stone Lithography at Edinburgh Printmakers

Luther grants can have a wager what is some of the comet of drawings while others maybe painterly being built up with layers of color lithographic plates bring additional possibilities to the medium allowing for larger scale prints and photographic and digital images to be produced as autographs while the principle of fog Rafi is simple the possibilities are endless the materials and techniques used in the process or from any new marks and ways of working to add to the artists palette install mythography the blocks of fine grained love the graphic limestone are prepared by graining two stones together with different grades of carborundum grit with larger stones a leather Gator disk may be used with grit grinding removes the top surface of the stone removing the previous image and prepares a fresh clean surface ready for a new image care must be taken during stone draining to ensure that the stone surface is flat and level to ensure the stone will print evenly larger blocks can be heavy so using a lift trolley and roller shelves eases handling proper shelves protect the stones edges from being chipped during storage once the stone is prepared the image is usually drawn directly onto the stone surface using a special kind of waxy ink known as Tish the toosh comes in Korean and Lloyd could form so a wide range of marks can be made one of the main characteristics are still mythography is its ability to allow the artist a direct approach to making marks on the stone this directness allows the artist to treat drawing on the stone in the same way as drawing directly on paper with the flexibility to lighten and remove marks by scraping and then add further marks with ink the liquid Tish can be diluted to create painterly effects similar to watercolour when applied wet it can create wonderful textures known as reticulation x’ there are a number of other approaches to making in the on the stool in this case the stone has been covered with ink then grit is used to rub the ink off to create light areas on a dark background alternatively images can be transferred to the stone using photocopy or laser printers transferred with the solvent allowing photographic or digital images to be printed from stone after transferring the image can be further manipulated with to screen or ink to enrich the image once the image is completed the stone is processed so that it can be printed a coating of talc is applied to the drawing fold by a coating of gum arabic the gum arabic coats all the areas of the stone which are not already covered with ink sealing the stone with a thin coating once the gum arabic coating has been left to dry the ink is washed away with solvents and replaced with an oilier printing ink the stone is then sponge with water which lifts the oily ink from the white areas of the drawing the stone is kept down for the sponge while it is inked up with stiff oil-based printing ink throughout the inking process the water acts as a barrier it is through this opposition of oil and water that lithography works having inked is still in several times the oily ink stains is stone more deeply making the image more durable ready for printing at this point further changes can be made to the drawing either removing ink by scraping are using mixtures of gum and acid to lighten or remove marks before printing a further coating of gum arabic mixed with acid is applied and allowed to drive our preparations are made for printing special stiff oil-based printing ink is next to the desired color and then stiffened with the addition of magnesium carbonate powder the ink is spread on the glass slab and rolled out with the printing roller to a thin even thickness then the black ink is washed off replaced with color ink before sponging with water and the stone is inked while the stone is kept dampened with water under sponge this cycle of sponging and inking is repeated several times to allow the ink to build up gradually on the image ensuring that all the tone and subtlety of the image is retained once fully inked the paper is placed on the stone and run through the press under high pressure to transfer the ink to the paper the next print is then taken by repeating the cycle of sponging and rolling up the stone with ink several times for each print multicolor prints are usually produced by creating a sector image on stone for each color to be printed this may be done by using several stones or alternatively by cleaning the stone after each color to prepare it for the next color when working with several stones an outline of the composition may be traced onto the stone as a guide the paper on stone are marked so that each color will be aligned correctly inks can be next to be transparent so they mix with the colors previously printed this process of layering can be used either to produce a number of identical prints in a limited edition or to produce several unique prints with different color qualities blended rolls of more than one color can also be used you
