. Core Technical Prepress Responsibilities

Artwork Inspection & Preflighting
- Analyze Incoming Files: Inspect client design files (AI, PDF, EPS, PSD) for resolution, embedded fonts, linked assets, missing elements, and dielines.
- Color Mode & Separation Audit: Convert RGB/CMYK files into press-ready separations (Process CMYK + Spot/Pantone colors) tailored to the client's press capacity.
- Assess Printability: Check for flexo limitations such as text size (positive and reverse), minimum stroke weight, and barcode readability (scaling and truncation rules).

Flexo-Specific File Optimization
- Trapping & Bleed Management: Apply accurate choke/spread trapping values based on substrate and press type (e.g., corrugated, film, label, or woven sack) to prevent misregistration gaps on press.
- Dot Gain Compensation (DGC) & Bump Curves: Apply appropriate compensation curves (press curve / plate curve) to ensure smooth vignettes and prevent harsh highlight drop-offs.
- Minimum Dot Management: Eliminate unstable highlight dots below the safe minimum holding threshold (e.g.,



0.8%2% depending on screening technology like HD Flexo or flat-top dot).
- Distortion & Elongation Calculation: Accurately calculate and apply stretch/distortion percentages along the print cylinder circumference based on plate thickness, sticky-back/tape thickness, and cylinder repeat length.
- Screen Ruling & Angle Setting: Set appropriate screen rulings (LPI) and screen angles per separation to avoid moir patterns and ensure clean ink laydown on specific anilox roll configurations.

Layout, Imposition & Step-and-Repeat
- Plate Layout Imposition: Build step-and-repeat layouts optimizing polymer plate area utilization while maintaining correct cylinder repeat and web width.
- Press Mark Integration: Position essential press aids accurately:
- Register marks and micro-dots for plate mounting alignment.
- Bearer bars / bearer tracks to stabilize printing pressure across cylinders.
- Eye marks for slitters/
