Drawing Aids, Continued
The purpose of an ink riser is to raise the drawing aid slightly off the
drawing surface so that ink will not bleed underneath it. If you do much ink
work, put ink risers on the back of the drawing aid you use most frequently.
To make an ink riser, follow this table:
Clean the back of the drawing aid.
Evenly cover the back with masking tape, taking care not to
Add a second layer of tape at right angles to the first layer.
With a fresh, sharp blade, cut openings approximately 3/32 larger
than the openings of the template or the edge of the triangle or
Remove unwanted tape.
Periodically clean riser and remove and replace as necessary.
Figure 2-54 shows a 30/60-degree triangle with an ink riser of masking tape.
