The paper grain might show up in the image. Draw or paint on clear plastic or thin paper. Try marking pen, India ink, film opaque. Shadings in pencil may or may not not come out well. Use paper or rubylith and cellophane cutouts or make photograms.
Special effects Make layers of multiple coatings.
Make four color separations and print in yellow, magenta, cyan and black, or use any colors and as many layers as you want. After exposing, processing and drying one layer, coat and process additional times. Use the same negative with different colors, or try different exposure times for different layers, different thicknesses or transparancies of solutions for different layers, or use different negatives. For best results with registration, preshrink paper by wetting it in warm water for several minutes and letting it dry before making the first coating. Make registration marks with pencil or tape before coating next color.
