Etching Grounds Lascaux (which are now sold in my web-shop)
- Lascaux Hard Resist is a liquid hard ground which is painted onto the printing plate with a wide flat nylon brush. It takes a little practice to paint it on thinly and evenly enough that it is still comfortable to work in. In my book and on my website you will find instructions on how to apply this etching ground .
- Lascaux Plate Backing Resist is an excellent alternative to adhesive packing tape to cover the backside of the printing plate during etching. It is easy to apply by brush and it hardens in 10 minutes in the drying cabinet. Instructions can be found on my website.
- Lascaux Aquatint Spray Resist is an excellent alternative to the Badger Acrylic Aquatint – it is easier to spray a thin and even layer on the printing plate and it does not clog the air-brush as easy as the Badger Acrylic Aquatint. Instructions can be found on my website.
- The Lascaux acrylic resists also include an excellent Stop Out Resist for local coverage during etching. Instructions can be found on my website.
- Important: Etching grounds from Lascaux cannot be removed with soda or caustic soda – they can only be removed with Mystrol, a strong non-toxic cleaning agent for floors. Mystrol is available in my shop.
Fast-made version of my slow-drying soft ground
Melt 1 part soy wax (available in flakes – used for non-toxic candles ) with 1 part black Charbonnel lithographic printing ink (3-5 grams of each) in a metal cover/lid on a hot plate, stir with a wooden stick and let it get cold. Heat a copper plate on the hot plate, melt a lump of the mixture (soft ground ) on the copper plate and roll or dab it out in a thin uniform layer. Let the copper plate with the soft ground cool down to room temperature and the plate is ready to be worked in. When you are finished, etch the soft ground 30-50 min. in 12,5 Beaumé ferric chloride . The etching ground can be removed with salad oil . The soft ground will keep soft for approx. 2-3 days before it starts drying. (Soy wax is available in many hobby shops alternatively you can use soy wax from a candles).
Paint the area to be lifted from the printing plate with melted soy wax on the printing plate. Let the wax air dry completely on the plate and paint over the plate with Lascaux Hard Resist the same way as you would apply it as a hard ground. Let the plate dry at room temperature 10 minutes or until it is touch-dry. Dry it with a hair dryer and the hard resist hardens like any other acrylic etching grounds where it is located directly on the printing plate, while the lift media melts and can be removed with a cloth. The plate is degreased and can now be etched right away creating open bites or sprayed with aquatint before etching.
Drawing Tools for Acetate Film and Copper Plates
For drawing on acetate for photopolymer gravure with following exposure to UV-light
- Good quality Watercolour Pencil gray or black. ”Koh-I-Noor Progresso Aquarell” is very good but other acknowledged brands are also working well, like the aquarellable pencil from Stabilo number 8008 (for paper, glass, plastic and metal.
- The best permanent markers for lines in all thicknesses that are completely resistant to UV-exposure is uniPOSCA (black).
For drawing and blocking out directly on the copper plates
The best permanent markers for drawing and blocking out directly on copper plates before or after application og aquatint that are completely resistant to acid or ferric chloride come is uniPOSCA (black). It comes in different thicknesses.
