• Which color model is primarily used for print production?

a) RGB

b) HSB

c) CMYK

d) LAB

Rationale: CMYK (Cyan, Magenta, Yellow, Key/Black) is the standard

color model used in printing, as it represents inks rather than light.

• What is the purpose of a trapping technique in prepress?

a) To reduce ink usage

b) To prevent gaps between colors in printing 1 / 4

c) To speed up printing

d) To enhance color saturation

Rationale: Trapping creates slight overlaps between adjacent colors

to compensate for misregistration during printing.

• Which type of file is most appropriate for vector graphics?

a) JPEG

b) PNG

c) SVG

d) BMP

Rationale: SVG (Scalable Vector Graphics) is vector-based and can

scale without losing quality, unlike raster formats like JPEG or PNG.

• What is the main function of a flexographic press?

a) High-resolution photographic printing

b) Printing on non-porous and flexible substrates

c) Producing fine art prints

d) Printing with high ink density only

Rationale: Flexographic printing uses flexible relief plates and is ideal

for packaging, labels, and non-porous substrates.

• What does DPI stand for in printing?

a) Digital Print Index

b) Dots Per Inch

c) Digital Print Image

d) Density Per Ink 2 / 4

Rationale: DPI measures print resolution by counting the number of

dots per inch; higher DPI means higher detail.

• Which process removes background color from a scanned image for

printing?

a) Flattening

b) Masking

c) Color separation

d) Trapping

Rationale: Masking allows selective removal or transparency of

backgrounds in images, essential in prepress.

• What is the purpose of a G7 calibration in printing?

a) To enhance ink drying

b) To increase press speed

c) To standardize gray balance and tonal values

d) To adjust paper thickness

Rationale: G7 calibration ensures consistent grayscale and color

reproduction across different presses and substrates.

• Which type of ink is commonly used in lithography?

a) Water-based ink

b) Oil-based ink

c) UV-cured ink

d) Latex ink 3 / 4

Rationale: Lithographic printing traditionally uses oil-based inks that

adhere to the image area and repel water on non-image areas.

• What is the purpose of an anilox roll in flexography?

a) To clean the plate

b) To transfer precise amounts of ink to the plate

c) To apply coating

d) To dry the substrate

Rationale: The anilox roll meters ink consistently, ensuring uniform

coverage on the printing plate.

• Which term describes the difference between light and dark

areas of an image?

a) Hue

b) Saturation

c) Contrast

d) Opacity

Rationale: Contrast refers to the visual difference between the

darkest and lightest areas in an image.
