How to Choose the Best Printing Solution Among Offset, Gravure, Flexo, Screen, and Surface Printing?
Selecting the optimal printing solution among offset, gravure, flexographic, screen, or surface printing requires a comprehensive evaluation based on substrate characteristics, printing requirements, production volume, cost considerations, and special needs. Below is a detailed analysis and selection logic.
I. First, Clarify the Core Characteristics of Each Printing Method
Printing Method | Core Advantages | Main Limitations | Typical Application Scenarios |
Offset (Lithography) | Accurate color reproduction, high detail (175–300 LPI), suitable for complex patterns; good paper adaptability. | Limited to flat substrates (e.g., paper, cardboard); thin ink layer, relatively poor abrasion resistance. | Books, magazines, posters, high-end paper boxes |
Gravure (Intaglio) | Thick ink layer (vibrant colors), strong adhesion, excellent weatherability; suitable for high-volume production (fast speed). | Extremely high plate-making cost (metal cylinder engraving); not cost-effective for small batches; solvent-based inks are less environmentally friendly. | Plastic films (food bags), tobacco and liquor packaging, wallpaper |
Flexo (Flexographic) | Wide substrate compatibility (paper, plastic, metal, glass); uses water-based/UV inks, environmentally friendly; low plate-making cost, suitable for small to medium batches. | Slightly lower detail (100–150 LPI); weaker reproduction of complex gradients. | Corrugated boxes, beverage labels, flexible food packaging |
Screen Printing | Extremely thick ink layer (strong 3D effect), adaptable to any substrate (flat, curved, irregular shapes); flexible for small batches. | Low efficiency (sheet-by-sheet printing), low detail (30–80 LPI), unsuitable for large batches. | T-shirts, glassware, metal signs, circuit boards |
Surface Printing | Inks printed directly on material surface, providing intuitive visual effects (high gloss); simple process. | Ink exposed, poor abrasion and scratch resistance (requires additional lamination for protection). | Plastic bag surface printing, simple labels (non-laminated films) |
II. Core Decision-Making Dimensions for Selection
1. Substrate Determines the Basic Direction
a. Paper/Cardboard (Flat): Prioritize offset (for fine detail) or flexo (for rough surfaces like corrugated board).
b. Plastic Film/Metal Foil: Gravure (high volume, high weatherability) or flexo (small to medium batches, eco-friendly).
c. Curved/Irregular Parts (Glass, Metal, Textiles): Only screen printing is suitable.
d. Requirement for Environmental Friendliness (Food/Children’s Products): Must choose flexo (water-based inks).
2. Printing Effect Requirements
a. High Detail (Gradients, Small Text): Offset (most precise) or gravure (alternative, suitable for packaging).
b. High Vividness/3D Effect (Thick Ink Layer): Screen printing (thickest ink layer) > gravure (relatively thick ink layer).
c. Abrasion/Water Resistance (Outdoor, Frequent Contact): Gravure (deep ink penetration) > flexo (UV inks as an option).
3. Volume and Cost
a. Large Volume (100,000+): Gravure (low unit cost after amortizing plate-making, fast speed).
b. Small to Medium Volume (10,000–100,000): Flexo (low plate-making cost, flexible changeovers).
c. Small Batch/Customization (100–1,000 pieces): Screen printing (no or low plate-making cost, easily adjustable).
d. Very Small Batch (e.g., Samples): Screen printing (no complex plate-making required).
4. Special Requirements
a. Environmental Compliance: Flexo (water-based inks) > offset (solvent-free options) > gravure (requires eco-friendly inks).
b. Surface Gloss/Tactile Feel: Surface printing (direct printing, good gloss) needs to be combined with gravure or flexo; for matte effects, flexo UV inks can be selected.
III. Typical Scenario Decision Examples
● Food Plastic Bags (Large Volume): Gravure (strong ink adhesion, weatherability, suitable for films).
● Corrugated Boxes (Medium Volume): Flexo (adapts to rough surfaces, eco-friendly).
● High-End Art Books (Small Batch): Offset (accurate color reproduction).
● Glass Cups (Customized, 100 pieces): Screen printing (adapts to curved surfaces, flexible for small batches).
● Supermarket Plastic Bags (Simple Patterns): Surface printing (using gravure process, printed directly on the surface to reduce costs).
Conclusion: Prioritize selection based on substrate and volume, then refine the solution based on details such as precision and environmental requirements. Surface printing should be implemented in combination with gravure or flexo methods; it is essentially a “surface printing” process choice rather than an independent printing type.
