Packaging and Label Design Printing Techniques and Finishes 1 — Questions and Answers
Question 1: Which printing process is most commonly used for high-volume flexible packaging and label production?
- Flexography (Correct answer)
- Offset lithography
- Screen printing
- Gravure
Correct answer: Flexography
Flexography uses flexible relief plates and fast-drying inks, making it the dominant process for labels, flexible packaging, and corrugated printing.
Question 2: What is a 'hot stamp' or foil stamping finish on a label?
- A metallic or holographic foil transferred to the substrate using heat and pressure (Correct answer)
- A sticker applied with heat
- A varnish applied with a hot roller
- A technique for embossing without foil
Correct answer: A metallic or holographic foil transferred to the substrate using heat and pressure
Hot stamping uses a heated die to transfer metallic or holographic foil from a carrier film to the label surface, creating a premium metallic effect.
Question 3: What is the difference between a gloss and matte varnish on a label?
- Gloss increases light reflection for vibrancy; matte diffuses light for a soft, tactile look (Correct answer)
- Gloss is water-based; matte is solvent-based
- Gloss is applied inline; matte is only applied offline
- Gloss protects against moisture; matte provides UV protection
Correct answer: Gloss increases light reflection for vibrancy; matte diffuses light for a soft, tactile look
Gloss varnish enhances color saturation and creates a shiny surface, while matte varnish absorbs light for a premium, understated appearance.
Question 4: What is 'digital printing' in the context of label production?
- Printing directly from a digital file without printing plates, enabling short runs and variable data (Correct answer)
- Any printing controlled by a computer
- Printing using UV-cured inks only
- High-resolution printing using inkjet technology exclusively
Correct answer: Printing directly from a digital file without printing plates, enabling short runs and variable data
Digital label printing (inkjet or electrophotographic) requires no plates, enabling short runs, personalization, and fast turnaround at competitive costs.
Question 5: What is 'embossing' on a label?
- Creating a raised three-dimensional design by pressing the substrate between a die and counterdie (Correct answer)
- Printing a design with thick, raised ink
- Applying a thick spot varnish to create texture
- Laminating a dimensional texture film to the label
Correct answer: Creating a raised three-dimensional design by pressing the substrate between a die and counterdie
Embossing mechanically displaces the substrate to create a raised relief design, adding tactile and visual premium cues without ink.
Question 6: What is UV coating on a label?
- A liquid coating cured by ultraviolet light to create a hard, glossy, protective finish (Correct answer)
- A coating that blocks UV light to protect the product
- A water-based varnish applied under UV lamps
- An ink system that glows under black light
Correct answer: A liquid coating cured by ultraviolet light to create a hard, glossy, protective finish
UV coatings are applied as a liquid and instantly cured by UV light, producing a durable, high-gloss finish that resists scuffing and moisture.
