CMI Visual Communication & Design Principles 3 — Questions and Answers
Question 1: Which rendering technique creates the illusion of three-dimensional form in a black-and-white anatomical pen drawing by using closely spaced parallel lines that follow the surface contour?
- Stippling
- Cross-hatching
- Contour hatching (Correct answer)
- Scumbling
Correct answer: Contour hatching
Contour hatching uses lines that curve around the form to simultaneously suggest shadow and surface topology, enhancing the three-dimensional effect.
Question 2: When designing a color-coded diagram to be accessible to individuals with red-green color deficiency, the safest alternative color pair is:
- Red and green
- Blue and orange (Correct answer)
- Purple and red
- Green and yellow
Correct answer: Blue and orange
Blue-orange contrasts are distinguishable by people with the most common forms of color vision deficiency because they differ in both hue and luminance.
Question 3: A medical illustrator is asked to create an exploded-view diagram of a joint prosthesis. The primary purpose of the exploded view is to:
- Show the device in its functional position within the body
- Reveal the spatial relationship and assembly order of individual components (Correct answer)
- Demonstrate the range of motion post-implantation
- Illustrate the device at actual anatomical scale
Correct answer: Reveal the spatial relationship and assembly order of individual components
An exploded view separates components along assembly axes to clarify how individual parts relate spatially and in what sequence they are assembled.
Question 4: In print production for a medical textbook, the color mode that should be used for final file delivery is:
- RGB at 72 dpi
- CMYK at 300 dpi (Correct answer)
- RGB at 300 dpi
- Indexed color at 150 dpi
Correct answer: CMYK at 300 dpi
Print output requires CMYK color mode at a minimum of 300 dpi to ensure accurate color reproduction and sufficient resolution for fine anatomical detail.
Question 5: The term 'negative space' in medical illustration refers to:
- Areas of shadow rendered in dark tones
- The background or unoccupied area that defines and supports the subject (Correct answer)
- White space reserved for labels and callouts
- Regions of anatomy removed in a cutaway view
Correct answer: The background or unoccupied area that defines and supports the subject
Negative space is the area surrounding and between subjects; when used deliberately it clarifies the positive form and reduces visual clutter.
Question 6: A ghosted or phantom view in surgical illustration is best described as:
- A view that removes all surface anatomy to show deep structures
- A technique that renders overlying tissues as semi-transparent to reveal underlying structures (Correct answer)
- A cross-section cut perpendicular to the long axis
- A perspective view using two-point perspective
Correct answer: A technique that renders overlying tissues as semi-transparent to reveal underlying structures
The ghosted (phantom) view retains the outer surface as a translucent overlay, allowing viewers to simultaneously understand surface location and underlying anatomy.
Question 7: Visual weight in an anatomical composition is most influenced by which combination of factors?
- Font choice and page margin width
- Size, color saturation, and contrast of elements (Correct answer)
- Paper stock and binding method
- Label quantity and arrow length
Correct answer: Size, color saturation, and contrast of elements
Larger, more saturated, and higher-contrast elements attract more visual attention and therefore carry greater visual weight within a composition.
