File Setup & Print Specifications

Set up files at 300 DPI at actual print size (e.g., 12" x 14" for full front print). Add 0.125" bleed beyond edges. Keep critical elements (text, logos) 0.125" inside safe zone. Export as vector (AI, EPS, PDF) or high-res raster (PNG) with transparent background.

Document Setup (Illustrator)

• Dimensions: Match print area (12" x 14" for full front, 3" x 3" for left chest)
• Color mode: RGB (for DTG/digital) or CMYK (for screen printing)
• Resolution: 300 DPI minimum (for raster effects)
• Artboards: Set to print size
• Units: Inches (easier for print specs)

Document Setup (Photoshop)

• Width x Height: 3600 x 4200 pixels (for 12" x 14" at 300 DPI)
• Resolution: 300 DPI (pixels/inch)
• Color mode: RGB 8-bit
• Background: Transparent (check "Transparent" in New Document)

Bleed & Safe Zone Explained

Bleed Area (0.125" - 0.25")

Bleed is extra artwork that extends beyond the final print edge to avoid white borders during cutting/alignment.

• Standard bleed: 0.125" (1/8 inch) beyond trim edge
• Why needed: Printing/cutting isn't perfectly precise. Bleed ensures no white gaps.
• How to add: Extend background colors/patterns into bleed area
• What to avoid: Don't put important elements in bleed (they may get cut off)

Safe Zone (0.125" - 0.25" inside)

Safe zone is the area inset from edges where critical elements (text, logos) must stay to prevent cropping.

• Standard safe zone: 0.125" inside final trim edge
• Why needed: Ensures text/logos aren't accidentally cut during production
• How to create: Use guides or offset paths (Object > Path > Offset Path in Illustrator)
• Rule: Keep all text and important graphics inside safe zone

Print Area Specifications

Export Settings

For Screen Printing (Vector):

• Format: EPS or AI (vector)
• Fonts: Convert to outlines (Type > Create Outlines)

• ✅ Background is transparent (PNG/EPS)
• ✅ Colors are RGB (DTG) or CMYK/Pantone (screen printing)
• ✅ File format matches printing method

Design Principles for Apparel

Good t-shirt design follows core principles: balance, simplicity, hierarchy, contrast, and unity. Keep designs uncluttered, readable from 10 feet away, and focused on one clear message. Less is more — simple designs have more impact.

1. Balance

• Symmetrical balance: Elements evenly distributed (stable, formal feel)
• Asymmetrical balance: Uneven distribution that still feels balanced (dynamic, modern)
• Tip: Center-align logos, offset text for visual interest

2. Simplicity (Less is More)

• Complex designs get lost on fabric
• Simple designs are more memorable and versatile
• Easier to print (fewer colors, lower cost)
• Wearable in more contexts
• Rule: If you can remove an element without hurting the design, remove it

3. Hierarchy (Visual Priority)

• Guide the viewer's eye with size, color, placement
• Main message = largest/boldest
• Supporting text = smaller, lighter weight
• Create clear focal point (what do you want seen first?)

4. Contrast (Readability)

• High contrast between design and shirt color
• Dark designs on light shirts, light designs on dark shirts
• Test from 10 feet away — can you read it?
• Use bold weights for small text

5. Unity (Cohesion)

• All elements should feel like they belong together
• Match font styles to design theme
• Consistent color palette
• Complementary shapes and styles

6. Repetition & Rhythm

• Repeat shapes, colors, or patterns for visual flow
• Creates movement that guides the eye
• Builds cohesive brand identity

The 10-Foot Test

Stand 10 feet away from your design. Can you:

• Read the text clearly?
• Understand the message instantly?
• See all important elements?

If not, simplify or increase contrast.

Typography for T-Shirts

Typography conveys emotion and sets tone. Use 2-3 fonts maximum. Pair contrasting styles (bold + script, serif + sans-serif). Prioritize readability over decorative flourishes. Adjust kerning, tracking, and leading for professional results.

Font Selection Rules

• Limit to 2-3 fonts total (1 for headlines, 1 for body, optional accent)
• Pair contrasting styles: Bold display font + clean supporting font
• Avoid similar fonts: Don't pair two sans-serifs or two serifs
• Match to theme: Vintage = retro fonts, modern = geometric sans-serifs, elegant = serifs

Font Categories & Emotion

Typography Spacing (Crucial!)

Kerning (Space Between Individual Letters)

• What: Adjusts space between specific letter pairs (e.g., "AV" needs tightening)
• Goal: Visually equal spacing (not mathematically equal)
• Larger type: Tighten kerning for impact
• Smaller type: Loosen slightly for readability
• How (Illustrator): Place cursor between letters, Alt/Option + arrow keys

Tracking (Space Across All Letters)

• What: Adjusts spacing across entire words/paragraphs
• Goal: Even "grayness" across text block
• Headlines: Tighter tracking (-10 to -30)
• Body text: Default (0) or slightly open (+5 to +10)
• All caps: Increase tracking (+50 to +100) for readability

Leading (Space Between Lines)

• What: Vertical space between lines of text
• Rule of thumb: Leading = font size × 1.2 to 1.5
• Example: 12pt font = 14-18pt leading
• Tight leading: Feels cramped, hard to read
• Open leading: Feels airy, easier to scan

Readability Tips

• Avoid all caps for long text (harder to read, feels shouty)
• Don't use overly decorative fonts for body text
• Avoid thin fonts on dark shirts (they disappear)
• Test at small sizes — if unreadable at 12pt, choose different font
• Align text carefully — centered for balance, left-aligned for readability

Font Pairing Examples

• Classic: Helvetica (headlines) + Georgia (body)
• Modern: Futura (headlines) + Open Sans (body)
• Vintage: Bebas Neue (headlines) + Courier (body)
• Elegant: Playfair Display (headlines) + Lato (body)
• Bold: Impact (headlines) + Arial (body)

Color Theory for T-Shirt Design

Colors evoke emotions and affect readability. Use 2-4 colors maximum. Ensure high contrast between design and shirt color. Test on actual fabric colors before printing. Understand RGB (digital/DTG) vs CMYK (print) vs Pantone (exact match) color modes.

Color Psychology

• Red: Energy, passion, urgency, excitement (sports, sales)
• Blue: Trust, calm, professionalism (corporate, medical)
• Green: Nature, health, growth (eco-friendly, wellness)
• Yellow: Optimism, happiness, attention (youth, cheerful)
• Black: Sophistication, power, mystery (luxury, fashion)
• White: Purity, simplicity, cleanliness (minimalism, healthcare)
• Orange: Creativity, enthusiasm, fun (playful brands)
• Purple: Luxury, creativity, spirituality (premium, unique)

Color Harmony Rules

Complementary Colors (Opposite on Color Wheel)

• Examples: Red/Green, Blue/Orange, Yellow/Purple
• Creates maximum contrast and vibration
• Use for bold, attention-grabbing designs

Analogous Colors (Next to Each Other)

• Examples: Blue/Green/Teal, Red/Orange/Yellow
• Creates harmonious, cohesive feel
• Use for calm, unified designs

Monochromatic (Shades of One Color)

• Example: Navy, blue, light blue, powder blue
• Creates elegant, sophisticated look
• Easy to execute, always works

Contrast for Readability

Color Modes Explained

RGB (Red, Green, Blue)

• Use for: DTG printing, digital designs, on-screen viewing
• Color range: Widest gamut (brightest, most vibrant)
• How it works: Additive color (light-based)
• Example: Neon colors look great in RGB

CMYK (Cyan, Magenta, Yellow, Black)

• Use for: Screen printing (process colors), offset printing
• Color range: Narrower than RGB (duller, less vibrant)
• How it works: Subtractive color (ink-based)
• Note: Converting RGB to CMYK may shift colors

Pantone (Spot Colors)

• Use for: Screen printing with exact color matching
• Color range: Specific pre-mixed inks (consistent across printers)
• Example: Coca-Cola Red = Pantone 185
• Cost: Each Pantone color = separate screen setup fee

Color Quantity Rules

• 1 color: Cheapest, boldest, most impact (e.g., black on white)
• 2 colors: Classic, versatile, affordable
• 3-4 colors: Colorful without being chaotic
• 5+ colors: Screen printing gets expensive; consider DTG instead
• Full-color (CMYK): Use DTG or sublimation, not screen printing

Common Design Mistakes to Avoid

1. Low Resolution Files

Problem: Design looks great on screen but prints pixelated and blurry.

Cause: File created at 72 DPI (screen resolution) instead of 300 DPI (print resolution).

Fix: Always design at 300 DPI at actual print size. You cannot increase resolution after the fact.

2. Using Too Many Fonts

Problem: Design looks cluttered, unprofessional, confusing.

Cause: 4+ different fonts competing for attention.

Fix: Limit to 2-3 fonts total. Stick to clear hierarchy.

3. Poor Contrast

Problem: Design is hard to see on the shirt color.

Cause: Dark design on dark shirt, or light design on light shirt.

Fix: Test design on actual shirt mockup. Ensure high contrast.

4. Text Too Small

Problem: Words are unreadable from normal viewing distance.

Cause: Tiny font size (under 12pt) or thin font weight.

Fix: Use minimum 14pt for body text, 24pt+ for headlines. Test from 10 feet away.

5. Ignoring Safe Zones

Problem: Text or logos get cut off during printing.

Cause: Elements placed too close to print area edges.

Fix: Keep all critical elements 0.125" inside print boundaries.

6. White Background on PNG

Problem: Design has white square around it on dark shirts.

Cause: PNG saved with white background instead of transparent.

Fix: Always use transparent background for PNG files.

7. Not Converting Fonts to Outlines

Problem: Printer doesn't have your font, text changes or disappears.

Cause: Fonts not embedded or outlined in vector files.

Fix: Convert all text to outlines (Type > Create Outlines in Illustrator) before sending files.

8. Design Too Complex

Problem: Too many details get lost on fabric.

Cause: Overdesigning — adding too many elements, effects, colors.

Fix: Simplify. Remove anything that doesn't strengthen the core message.

9. Not Testing on Mockups

Problem: Design looks different than expected on actual shirts.

Cause: Didn't preview on realistic mockup with shirt color/texture.

Fix: Use mockup generators to test on various shirt colors before printing.

10. Poor Spelling/Grammar

Problem: Typos, missing punctuation, grammatical errors.

Cause: Not proofreading before sending to print.

Fix: Have 2-3 people proofread. Read backwards. Check punctuation carefully.
