CDA Technology & Digital Tools 2 — Questions and Answers
Question 1: Which file format is best for saving a digital painting that requires a transparent background for use in print layouts?
- JPEG
- PNG (Correct answer)
- BMP
- GIF
Correct answer: PNG
PNG supports lossless compression and alpha channel transparency, making it ideal for layered print compositions.
Question 2: In digital art software, what does the 'multiply' blend mode do to overlapping layers?
- Lightens the underlying layer
- Darkens by multiplying pixel values (Correct answer)
- Inverts the colors of both layers
- Averages the color values of both layers
Correct answer: Darkens by multiplying pixel values
Multiply mode multiplies the pixel values of the two layers, always resulting in a darker tone — useful for shadows and glazing effects.
Question 3: A decorative artist wants to vectorize a hand-drawn stencil design for scalable reproduction. Which software is most appropriate?
- Adobe Photoshop
- Adobe Illustrator (Correct answer)
- Procreate
- GIMP
Correct answer: Adobe Illustrator
Adobe Illustrator is a vector-based program that allows infinitely scalable artwork without pixelation, ideal for stencil reproduction.
Question 4: What is the primary advantage of using a graphics tablet with pressure sensitivity when doing digital decorative art?
- It automatically corrects color profiles
- It enables variable brush opacity and stroke width based on stylus pressure (Correct answer)
- It converts raster art to vector automatically
- It eliminates the need for layer management
Correct answer: It enables variable brush opacity and stroke width based on stylus pressure
Pressure-sensitive tablets mimic the natural variation of traditional brushwork, giving digital strokes a more organic feel.
Question 5: Which color model is used for digital screens and should be selected when creating artwork intended for digital display?
- CMYK
- Pantone
- RGB (Correct answer)
- LAB
Correct answer: RGB
RGB (Red, Green, Blue) is the additive color model used by monitors and digital screens.
Question 6: When digitizing a pattern for fabric or wallpaper repeat, what term describes the seamless tiling method where the design mirrors along its edges?
- Drop repeat
- Half-drop repeat
- Mirror repeat (Correct answer)
- Random scatter
Correct answer: Mirror repeat
A mirror repeat reflects the design along its edges so that adjacent tiles create a symmetrical, seamless connection.
Question 7: A decorative artist uses an airbrush simulator in digital software. Which brush setting most closely mimics the paint-to-air ratio of a real airbrush?
- Hardness
- Flow (Correct answer)
- Spacing
- Angle
Correct answer: Flow
The Flow setting controls how much paint is applied per stroke, simulating the volume of paint pushed through an airbrush.
