Level II Intermediate Practice Exam

Flexographic Press Operator Certification Level II (Intermediate) Practice Exam Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

• What is the primary reason to verify plate-to-cylinder mounting

accuracy in intermediate flexo workflows?

• To reduce ink foaming
• To ensure proper register alignment
• To prevent plate swelling
• To increase ink transfer
• To prevent plate swelling

Rationale: Proper mounting prevents distortion and incorrect contact that

leads to swelling and misprints.

• Which anilox characteristic has the greatest effect on ink film thickness?
• Cell angle
• Roll width 1 / 4

• BCM volume
• Screen count alone
• BCM volume

Rationale: BCM volume determines how much ink is delivered to the plate.

• What is a common cause of haloing around fine text?
• Excessive impression
• Low anilox volume
• Over-inked plate
• Incorrect drying temperature
• Over-inked plate

Rationale: Excess ink spreads around edges, creating a halo effect.

• Which humidity level is ideal to control paper curl during flexo

production?

A. 10–20%

B. 20–25%

C. 45–55%

D. 65–75%

C. 45–55%

Rationale: Mid-range humidity helps stabilize paper substrates.

5. A misaligned doctor blade typically causes:

• Gear streaks
• Dot bridging 2 / 4

• Ink spitting or chatter
• Slurred print
• Ink spitting or chatter

Rationale: Misalignment prevents even metering, leading to unstable ink

release.

• What is the primary benefit of chambered doctor blade systems?
• Faster plate mounting
• Controlled ink containment and metering
• Better plate cleaning
• Lower impression requirements
• Controlled ink containment and metering

Rationale: Chambers maintain stable ink supply and consistent pressure.

• What typically causes slur in flexo printing?
• Low ink viscosity
• High drying temperature
• Excessive web tension
• Proper plate durometer
• Excessive web tension

Rationale: Over-tension pulls the substrate, elongating dots or lines.

• What is the main purpose of a viscosity cup?
• Measuring ink pH
• Measuring ink flow time 3 / 4

• Checking anilox wear
• Measuring plate thickness
• Measuring ink flow time

Rationale: Flow time indicates viscosity and ink behavior.

• Which plate hardness is best for rough corrugated board?
• 35 durometer
• 45–55 durometer
• 65–75 durometer
• 80–90 durometer
• 45–55 durometer

Rationale: Softer plates conform better to uneven surfaces.

• What is the primary effect of increasing impression pressure?
• Less dot gain
• Reduced ink density
• Increased dot size and filling
• Lower substrate stretch
• Increased dot size and filling

Rationale: Extra pressure squeezes dots, enlarging them.

• When switching from solvent to water-based ink, what equipment

adjustment is often required?

• Lower drying temperature
• Lower pH
• / 4
