If the designing paper becomes greasy, the colors will not adhere. To cure this take a moist sponge and wipe off the paper.
Preservation of Textile Designs.
To prevent textile designs (painted on the □ designing paper) from being soiled, apply a thin solution of white shellac varnish, which dries almost instantaneously. A design preserved in this manner can be cleaned off at any time with a wet sponge, and after years have passed will appear bright and distinct.
Sketching of Designs for Textile Fabrics to be Executed on the Jacquard Machine.
The first work to be done in making an original design, or in reproducing a design by making an analysis of a woven fabric, is to prepare the “sketch.” This sketch may be arranged the exact size of pattern needed, or it may be proportionally larger or smaller. If the design is a reproduction from a woven fabric, a correct duplicate on the regular drawing paper is required; for this sketch is of the same value to the designer for Jacquard work as the correct picking out of a weave is to the designer for harness loom-work.
In preparing an original sketch, the points to be considered are: The setting of the figure, and the most practical size.
Methods of Setting the Figures.
To give a clear illustration of this, Figs. [69], [70], [71], [72], [73], [74], [75], and [76] are designed, representing a few of the methods most frequently used. A separate explanation of each will familiarize the student with this part of the work.
