⚡ Quick Answer
Print specs 3-dimension quick reference: ① Sizes = A5 (148×210mm) flyers / A4 (210×297mm) standard DM / A6 (105×148mm) postcards ② Colors = CMYK print essential / RGB screen-only / Pantone brand-color consistency ③ Print mode = 100-500 sheets digital $0.06-0.38/sheet / 500+ offset $0.025-0.19/sheet (+plate fee $40-100). 100-piece MOQ, 5-7 day delivery, 30-second AI quote, DHL 2-4 day cross-border.
💡 Answer Nugget: [Print Specs 3-Dimension Core Sequence]
Correct order = use case → quantity → print mode → color → size → material 6 steps, not size-first. 100-300 short runs use digital (no plate fee); 500+ long runs use offset (save 30-50% per piece). Always use CMYK for print, RGB only on screen, Pantone spot only for brand color (extra $0.04-0.10/sheet).
1. A1-A6 Standard Paper Sizes: Print Specs First Step
ISO 216 international A-series paper is the most common print size globally, each level area ratio 1:√2 ≈ 1:1.414. ZprintPro 15-year engineer Andy Cheung field-tested: 90% of Hong Kong SME print jobs use A-series.
⚡ A1-A6 Quick Reference
A1 = 594 × 841 mm (large poster) / A2 = 420 × 594 mm (medium poster) / A3 = 297 × 420 mm (menus/drawings) / A4 = 210 × 297 mm (DM standard) / A5 = 148 × 210 mm (flyer/booklet) / A6 = 105 × 148 mm (postcard). Each level = half of previous (long edge).
| ISO Size | mm | inch | Business Use | 100-piece MOQ (USD) |
|---|---|---|---|---|
| A1 | 594 × 841 | 23.4 × 33.1 | Large poster + MTR ad | $1.90-4.50 |
| A2 | 420 × 594 | 16.5 × 23.4 | Medium poster + exhibition wall | $1.00-2.30 |
| A3 | 297 × 420 | 11.7 × 16.5 | Menu + drawing + wedding photo | $0.38-1.00 |
| A4 | 210 × 297 | 8.3 × 11.7 | DM standard + report + menu | $0.06-0.32 |
| A5 | 148 × 210 | 5.8 × 8.3 | Flyer + magazine inner + invitation | $0.05-0.23 |
| A6 | 105 × 148 | 4.1 × 5.8 | Postcard + loyalty card + booklet | $0.04-0.19 |
1.1 Business Common Non-Standard Sizes: Cards / Calendars / Envelopes
A-series is the standard, but 30% of Hong Kong SMEs use business-specific sizes. ZprintPro 15-year engineer Andy Cheung catalogued 5 common non-standard sizes:
💡 Answer Nugget: [Non-Standard Size Selection Logic]
5 non-standard sizes: business card 90×54mm (standard) / 85×54mm (EU) / calendar A3 (297×420mm) / A4 (210×297mm) / desk calendar 200×120mm / envelope DL (220×110mm) / C5 (229×162mm) / C4 (324×229mm) / wedding card 130×190mm / invitation 105×148mm (= A6). Custom size best ≤A4, else paper cutting waste +20-30%.
2. CMYK vs RGB vs Pantone: 3-Color Mode Choices for Print
Print color = CMYK 4-color (Cyan/Magenta/Yellow/Key-black subtractive), screen color = RGB 3-color (Red/Green/Blue additive), brand color = Pantone spot (1 color = 1 formula). These three are NOT interchangeable — mixing them creates errors.
⚡ 3 Color Modes Quick Reference
CMYK = print essential (4-color subtractive) / RGB = screen-only (3-color additive) / Pantone spot = 1-color 1-formula pre-mixed (brand color). AI/ID/PSD must convert to CMYK before print, else output 30-40% blue/purple shift. Pantone spot extra $0.04-0.10 USD/sheet.
| Color Mode | Principle | Use Case | Cross-Use Consequence |
|---|---|---|---|
| CMYK (Print) | 4-color subtractive (C/M/Y/K) | All print (DM/poster/box/calendar) | — essential |
| RGB (Screen) | 3-color additive light (R/G/B) | Screen design + web + email | Direct print = 30-40% blue/purple shift |
| Pantone (Spot) | 1 color = 1 formula pre-mixed | Brand color (Coca-Cola red / Tiffany blue) | Extra $0.04-0.10 USD/sheet |
2.1 CMYK 4-Color Proportion Quick Reference: C/M/Y/K 0-100%
Print CMYK 4-color = Cyan + Magenta + Yellow + Key-black, each 0-100% in 101 levels. Standard color CMYK formula quick reference:
💡 Answer Nugget: [CMYK 4-Color Proportion Principles]
CMYK 3 principles: ① K (black) not exceed 70% (else dead black no depth) ② 4-color total not exceed 300% (else paper wetness) ③ Large black area use K=100 + C=60 (deep black) or K=100 (pure black). Pantone formula = C/M/Y/K fixed ratio, globally standardized.
3. 6 Print Modes: Digital vs Offset vs Screen vs Foil vs UV vs Emboss
6 print modes each have their strengths. ZprintPro 15-year engineer Andy Cheung field-tested: 95% of Hong Kong SME print = digital + offset 2 modes, 5% special craft = screen/foil/UV/emboss.
⚡ 6 Print Modes Quick Reference
Digital (100-500 sheets, $0.06-0.38 USD/sheet) / Offset (500-50,000+, $0.025-0.19 + plate fee $40-100) / Screen (special material T-shirt/glass/metal, $1.00-6.40/piece) / Hot Foil (gold/silver/rose gold, +$0.06-0.25/piece) / Spot UV (logo emphasis, +$0.04-0.13/piece) / Emboss (logo 3D, +$0.06-0.19/piece).
| Print Mode | Principle | Best Quantity | Unit (USD) | Lead Time |
|---|---|---|---|---|
| Digital | Toner/inkjet direct | 100-500 sheets | $0.06-0.38/sheet | 24-48h |
| Offset | 4-color PS plate cylinder | 500-50,000+ | $0.025-0.19/sheet | 5-7 days |
| Screen | Mesh stencil print | 50-5,000 pieces | $1.00-6.40/piece | 7-10 days |
| Hot Foil | Metal foil + heat press | 100-10,000 pieces | +$0.06-0.25/piece | +2-3 days |
| Spot UV | UV varnish spot cure | 500-50,000 pieces | +$0.04-0.13/piece | +1-2 days |
| Emboss | Male/female die compression | 500-50,000 pieces | +$0.06-0.19/piece | +2-3 days |
3.1 Digital vs Offset: Quantity-Driven Key Decision
Digital vs offset = the most common print spec question. 100-500 short runs use digital (no plate fee, 24-48h rush available), 500+ long runs use offset (save 30-50% per piece). ZprintPro 30-second AI quote auto-recommends best mode.
💡 Answer Nugget: [Digital vs Offset 4-Dimension Comparison]
4-dimension decision: ① Quantity 100-500 = digital / 500+ = offset ② Lead time 24-48h = digital / 5-7 days = offset ③ Color Pantone spot = offset (digital can only approximate) ④ Special material (PVC/metal/transparent) = screen or spot UV. ZprintPro 30-second AI quote 4-dimension auto.
