Flexographic Press Operator Level II Certification Practice Exam Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf
- What is the primary function of an anilox roller in a flexographic press?
a) To apply pressure to the substrate
b) To transfer a consistent ink film to the printing plate
c) To feed substrate through the press
d) To remove excess ink from the plate
Rationale: The anilox roller meters and transfers a controlled amount
of ink from the ink chamber to the plate surface, ensuring uniform ink coverage.
- Which factor most affects dot gain on a flexographic print?
a) Web speed
b) Impression pressure 1 / 4
c) Ink viscosity
d) Anilox cell count
Rationale: Excessive impression pressure can cause the plate dots to
squash, leading to increased dot gain and loss of image sharpness.
- What does LPI stand for in flexographic screening?
a) Lines per inch
b) Lines per inch
c) Length per inch
d) Linear point intensity
Rationale: LPI measures the number of halftone lines printed per
inch, determining image resolution.
- The term “doctor blade” refers to what component in flexography?
a) The blade that cuts substrate
b) The plate cleaning tool
c) The blade that meters ink on the anilox roller
d) The roller scraper for the substrate
Rationale: The doctor blade removes excess ink from the anilox roller
surface, ensuring precise ink film thickness.
- What is the main purpose of a chill roller in a flexographic press?
a) To clean the web
b) To control web temperature and prevent stretching
c) To apply adhesive
d) To remove ink 2 / 4
Rationale: Chill rollers cool the substrate after drying to prevent
heat-related distortion or elongation.
- What is the effect of using an anilox roller with higher cell volume?
a) Reduced ink laydown
b) Higher print resolution
c) Increased ink laydown
d) Lower ink transfer
Rationale: Higher cell volume rollers hold and transfer more ink,
increasing color density but potentially reducing fine detail.
- What type of ink is typically used for printing on plastic films in
flexography?
a) Water-based ink
b) Paste ink
c) Solvent-based ink
d) Oil-based ink
Rationale: Solvent-based inks adhere well to non-porous substrates
such as films and foils.
8. In flexography, plate mounting accuracy primarily affects:
a) Ink viscosity
b) Anilox cleaning
c) Registration and print quality
d) Ink pH balance 3 / 4
Rationale: Poor plate mounting leads to misregistration, blurred
images, and uneven print alignment.
9. A higher anilox cell count generally results in:
a) More ink transfer
b) Finer ink transfer and higher resolution
c) Thicker ink film
d) Lower dot gain
Rationale: Higher cell counts allow finer ink metering, improving
detail and tonal reproduction.
- Which drying method is most common for UV-curable
flexographic inks?
a) Hot air drying
b) Infrared drying
c) Ultraviolet curing
d) Electron beam drying
Rationale: UV-curable inks polymerize instantly when exposed to
ultraviolet light, providing fast curing.
- What is the function of the impression cylinder?
a) To support the substrate and apply pressure during printing
b) To carry the ink to the plate
c) To hold the plate
d) To meter the ink
