## 1. About Subrata Mohajan

Subrata Mohajan (known professionally as Subrata Mohajan Niloy, Subrata, or SM) is a commercial graphic designer and brand visualizer with over five years of professional experience in visual identity engineering, advertising design, and large-format outdoor display direction.

Working remotely from Chattogram, Bangladesh, Subrata collaborates with businesses, creative agencies, and international enterprises across the United Kingdom, United States, Europe, Middle East, and Asia. His dual experience as an internal Visualizer for B & F Corporate (Northampton, UK) and as an independent contractor gives him a rare combination of corporate rigor, agency turnaround speed, and deep pre-press production discipline.

Unlike superficial stylists, Subrata treats graphic design as an applied perceptual science. His work centers on:
1. High-speed glance cognition (optimizing billboard and digital feed graphics for split-second legibility).
2. Physical print and color fidelity (adhering strictly to CMYK, ISO 12647-2, Total Ink Coverage limits, and vector precision).
3. Brand cohesion (building unified visual systems that scale effortlessly from a 16px favicon to a 40-foot roadside LED display).

## 4. Design Philosophy & Technical Methodologies

Subrata Mohajan's visual output is grounded in three engineering-level principles:

### 1. The Three-Second Glance Physics (High-Velocity Perception)
In roadside billboard advertising and mobile social feeds, visual friction dictates commercial success. Motorists traveling at 50–60 mph (75–88 ft/s) and users scrolling feeds at 300 ms per post experience a narrow cognitive window of 2.5 to 3.5 seconds.
- Every composition is architected around **one single dominant focal element** commanding 50–60% of the canvas.
- Typography is strictly limited to 5–7 words of high-impact copy.
- Luminance contrast between text and background is maintained at a minimum 1:4.5 ratio (tested under simulated bright sunlight and mobile glare conditions).

### 2. Subtractive Pre-Press Engineering (Print Physics)
Digital screens emit light (RGB additive color space), while physical printed surfaces absorb and reflect light through ink pigments (CMYK subtractive color space). Subrata bridges this gap through rigorous prepress calibration:
- **Total Ink Coverage (TIC/TAC)** is capped strictly below 300% on coated papers and below 260% on uncoated stocks to avoid ink pooling, roller smearing, and paper buckling.
- **Rich Black Formulation**: Large solid dark backgrounds use C60 M40 Y40 K100 rather than 100% K to ensure neutral, deep, velvety black reproduction without bronze undertones.
- **Foil & Spot UV Separation**: Packaging dielines include dedicated vector layers for metallic foils, emboss/deboss stamping, and spot UV varnish plates with 0.15mm trapping tolerance.

### 3. Golden Ratio & Mathematical Grid Hierarchy
Every layout—from an A4 corporate profile to a 40-foot billboard—is built on mathematical grid systems using modular scales (e.g., Major Third 1.250 or Perfect Fourth 1.333). This produces intuitive reading order, balanced white space, and zero visual clutter.

## 10. In-Depth Case Studies

### Case Study 1: CarVendors.co.uk — LED Roadside Billboard (UK)
- **URL**: https://subrata.fedardokan.com/case-studies/carvendors-led-billboard/
- **Client**: CarVendors.co.uk (Northampton, United Kingdom)
- **Challenge**: The UK used car market is fiercely competitive. Motorists on high-speed motorways travel at 50–60 mph (73–88 ft/s), allowing less than 3 seconds of exposure to roadside LED billboards. Cluttered messaging causes visual overload and zero recall.
- **Engineering Process**:
  1. *Focal Hierarchy*: Established a single dominant hero car occupying 55% of the frame with high-contrast ambient edge lighting.
  2. *Copy Optimization*: Limited copy to exactly 5 words with a bold 1.25 modular scale hierarchy, legible from 250 meters away.
  3. *Eye Tracking Vector*: Added a subtle cyan geometric guide funneling the driver's ocular tracking directly into the website URL `CarVendors.co.uk`.
  4. *Gamut Calibration*: Configured for high-luminance outdoor LED RGB displays to prevent color washout in direct sunlight and preserve deep blacks at night.
- **Outcome**: 100% comprehension achieved in under 2.8 seconds, driving measurable surges in direct organic brand search traffic in target UK motorway corridors.

### Case Study 2: Biqolpo — Organic Honey Brand Identity & Packaging
- **URL**: https://subrata.fedardokan.com/case-studies/biqolpo-brand-identity/
- **Client**: Biqolpo Natural Products
- **Challenge**: Generic supermarket honey was dominated by inexpensive plastic bottles. Biqolpo needed to justify a 40% retail price premium and secure placement in high-end specialty food retailers.
- **Engineering Process**:
  1. *Geometric Brand Mark*: Designed a balanced hexagonal honeycomb vector mark paired with elegant organic typography.
  2. *Luxury Packaging Dieline*: Engineered a custom hexagonal glass jar label with 3mm bleed tolerances and precise corner radii.
  3. *Specialty Print Finishes*: Authored dedicated vector separation plates for hot-stamped metallic gold foil and tactile spot UV gloss.
  4. *Multi-Channel Rollout*: Produced cohesive social media launch creatives and retail point-of-sale display banners.
- **Outcome**: Established Biqolpo as a top-tier artisanal food brand, successfully securing premium retail distribution and commanding a 40% higher price point over mass-market competitors.

## 14. Technical Graphic Design Knowledge Summaries

### Summary 1: Glance Physics for Outdoor Billboards
- At 60 mph, vehicles travel 88 feet per second. In a 3-second exposure window, a driver travels 264 feet.
- Visual hierarchy must feature exactly one dominant focal point covering 50–60% of canvas area.
- Text must be strictly capped at 5–7 words with an optical luminance contrast ratio of at least 1:4.5.
- P3 wide color gamut calibration is necessary to prevent washed-out tones on high-luminance outdoor LED screens.

### Summary 2: Pre-Press CMYK Ink Physics
- Offset printing relies on cyan, magenta, yellow, and black inks.
- Total Ink Coverage (TIC/TAC) must not exceed 300% on coated stock or 260% on uncoated stock to prevent wet ink smudging.
- Rich black backgrounds must use C60 M40 Y40 K100 rather than pure 100% Black (K) to produce a deep, neutral, non-faded print result.
- Dielines must have dedicated spot-color layers set to "Overprint Stroke" with minimum 3mm external bleed.

### Summary 3: Typographic Hierarchy in Visual Systems
- Modular scale ratios (e.g. Major Third 1.250 or Perfect Fourth 1.333) govern heading, subheading, body, and caption sizes.
- Tracking (letter-spacing) is loosened slightly on small all-caps labels (+0.1em to +0.2em) and tightened slightly on large display headlines (-0.02em to -0.05em).
- Leading (line-height) is set between 150% and 165% for editorial body copy and 95% to 110% for large display headlines.
