Unlike many paper surfaces, drafting films are costly, tear resistant, and generally do not react to changes in temperature or humidity. They permit simple ink erasure and receive ink quite nicely. These films call for the use of special pencils. Original film drafting results in outstanding diazo prints and photocopies. Plastic film and ink drawings were regarded as the
best for replication years beforeOn vellum or bond drawings, roduction Film also known as appliqué film and usually referred to generally as "sticky back is employed. Images typed or printed can be photocopied or sketched onto adhesive replication film. After that, the film is precisely measured, sliced, then placed on bond paper or vellum. Matte appliqué films take
pencil nicely; some kinds are repositionable but others are not. While RayvenTM creates a range of films for low-, medium-, and high-heat copiers, high-heat photocopiers can cause buckling of some appliqué films Manual drawing usually calls for tracing paper, drafting vellum, and drafting film. Although they cannot be layered and do not re-produce well, non-
Transparent papers such fine art drawing papers can be used
with outstanding results. Transparency sheets are ideal for the nature of the design process, which calls for ongoing exploration and modification Design drawings are now produced using large-format photocopying machines. Many companies and offices have replaced blueprints with bond paper copies since coupled with clay and other materials creates what are usually
known as "lead" pencils. Used in design drawing, graphite pencils come in a spectrum of hardness depending on the clay to graphite mix.Graphite pencils and replaceable "leads" are coded using a standard classification system: H stands for hard, B for black (the softer leads). The figure found next to the H or B indicates the degree of hardness. A 6B, for instance, is
softer than a an 8H is somewhat rigid. F-rated leads lie in the middle of the range; HB leads are somewhat harsher than Bs. While H, 2H, and occasionally F leads are most usually utilized in drafting, sketching and rendering require the softer leads. Often graded differently than graphite leads, polymer-based leads used on plastic and polyester drafting films
Many mark making tools make use of the graphite discussed
above. Made from a graphite combination wrapped in wood, are sharpened like ordinary wooden writing pencils. MECHANICAL PENCILS are hollow tools featuring very fine graphite leads. These are offered in several lead widths to produce a range of line weights. Hollow tools designed to accept thicker leads than mechanical pencils called LEAD HOLDERS. Lead
holders tolerate a range of lead kinds in terms of softness even if they do not let any variation in lead widths. Lead holders need a specific sharpening called a LEAD POINTER. While NON-PHOTO-BLUE colored pencils do not replicate when photographed, specialized colored drafting pencils and leads can be used to create drawings prior to hard-lining them; Diazo
prints cannot faithfully replicate NONPRINT colored pencils. Where appropriate, both kinds of pencil can be laid out using gray kneaded erasers or pink erasers to show where soft pencil marks are readily lifted. Marks left with tougher leads can be erased with plastic and film erasers. Unwanted erasing is avoided on the drawing surface by means of a metal ERASER
Available to maintain drawing surfaces clean are Pads with
art gum powder sifting onto drawing surfaces. Technical pens have refillable ink reservoirs and tubular points. They come in point values that let one have complete line weight control Technical pens produce the best line work of any drawing tool because they use black ink and metal tips. They should be used with the suitable ink, advised by the manufacturer. Available
in a range of point sizes, DISPOSable Technical Pens mix a tubular support with a felt tip. These pens are easy to use since they demand no cleaning or upkeep. Disposable pens have lately improved a lot and are becoming somewhat popular even if they have been known to skip and produce irregular line work. Often used in sketching, exploration, and rendering,
FELT-TIP PENS come in a variety of styles and point values. Working drawings or improved drafted drawings usually do not call for felt-tip pens. Eliminating ink markings calls for specific erasers and is fairly challenging. Hard plastic erasers have ink removal ability. Still, an ELECTRIC ERASER with the suitable eraser insert is most helpful for ink removal. Though
Conclution
they are rather efficient, electric erasers should always be used with an eraser shield. On film, ink markings vanish more readily than on vellum. Sometimes one uses sharp razor blades to remove ink off of drawing surfaces.Successful drawing creation calls for a quality DRAWING BOARD. If at all possible, serious pupils have to get a premium drawing board. The board
should allow at least minimum paper size. Designed for drafting, sold before completion, drawing boards should be covered with a particular vinyl drawing surface One major benefit of graphite pencils is their simplicity in erasing. Often the most challenging to remove are harder leads; hence, method of reproductionesisting. Tyler is captivated by the forum users'
