Moving Picture Age (Jan-Dec 1922)

10 MOVING PICTURE AGE May, 1922 I i Fig. II. Front of Small Chart Board At the present time we are using at the University of Missouri one board like in Fig. I, one 6x8 ft., similar to that in Fig. It. and a large drawing board. The major part of our charts are made on cloth 63x72 in. The chart-maker will need a yard stick, a rule, and an 18-in. blackboard triangle in laying out his work. Charts may be made on tough paper ; detail drafting paper may be procured in sheets or rolls. This serves well for charts that are temporary or do not have to be folded. Paper charts may be made more substantial by reinforcing the edges with gummed paper or cloth tape. Linura cloth and blue-print cloth are filled linen cloths. These cloths are available in a variety of widths and have surfaces that will take paint, water color, ink, or pencil. They are rather expensive and should usually be rolled, not folded. Ordinary sign cloth is valuable for temporary charts. Its cost is slight — 10 to 20 cents a yard. It will not stand much handling on account of losing the filler. The most durable charts for all-around school use are made on bleached muslin. It is essential that great care be exercised when purchasing muslin, else results are not satisfactory. Pequot Brand or muslin of equal quality is very satisfactory. Insist on good muslin when buying. Each chart may be classified as to the form that the major part of its materials assume as follows : 1. Statement 2. Tabular matter 3. Graph (see Fig. I) 4. Map 5. Pictorial (see Figs. IV and V) 6. Diagrammatic 9. Cartoon Each school will need two or three fonts of rubber type"; this should be plain, round-cornered Gothic.2 This may be obtained in 3-, 2 Martin & Company, S. Clark Street, Chicago, and Salisbury, Schulz Company, Chicago, are, so far as I know, the only concerns making this style of type. 2y2-, 2-, \y2-, 1-, and %-m. sizes. It is to be regretted that this style type is not yet available in lower case as well as capitals. A sponge rubber or Buck's cushion mount makes the type much easier to use, and one can more readily secure first-class results. The manufacturers of the stamps will supply a high grade of black ink for use with these stamps. Ordinary stamp pads and ink will not do. A very serviceable stamp pad may be made as follows : Procure a tin box 1 in. deep with tight-fitting cover. A film vault-can is excellent; cost, 30 to 50 cents. From soft wood % in thick saw a piece l/2 in. smaller in diameter than the can. Now cut twenty discs of muslin the same diameter as the board, and two discs 2 in. larger in diameter. Lay the small discs on the board, cover with the large ones, and tack on back of board. Saturate with ink ; clean occasionally with a dry rag. Care should be taken not to use too much ink on the pad. The type is best inked by giving each letter a number of light taps on the pad rather than one heavy pressure. The ink must not be pushed up around edges of type if good results are to be obtained. When applying the type to the chart muslin plenty of pressure should be used. For brush work the beginner will find showcard colors most desirable. These will work on muslin without running. He will also need some showcard brushes of first-quality round red sable. Numbers 8 and 12 will meet most needs. Spoonbill and Payzant lettering A MALE FOWL ^ 4 Fig. III. Back of Small Chart Board Fig. IV. Pictorial Chart Made by a Visual-Education Student; Enlarged with Opaque Projector, Lines Made with Brush and Showcard Ink, Colorpastello Crayon. Note Style of Type pens will also be found useful. For lines of light tone or where finished results are not so essential, wax crayons and black colored paper pencils3 are very useful. For color work where blending and tone gradations are necessary we use pastello crayons rubbed into the cloth with the finger and cloth. After the chart is finished, the colors are prevented from smudging by applying Fixatif (white shellac and alcohol) with an atomizer. For work on prepared cloth, Linura, blue-print, or sign cloth, coach colors ground in japan and thinned with turpentine are very satisfactory. The opaque projector and stereopticon are useful in chart-making. Pictures and drawings may be projected onto the cloth and traced, either enlarged or reduced. Other methods of enlarging are by the use of the pantograph, free-hand, and method of greater squares. One of the most common errors in chart-making is that of making chart and type too small. Another that is just as bad is to try to put too much on one chart. "More think and less ink" is a good motto. The chart maker should ask himself: Is the chart the most effective medium for presenting this material under my conditions? Does this material lend itself to chart presentation?
