About This Role
The Packaging Designer inspects and optimizes client design files for flexographic printing, ensuring they are press-ready and meet quality standards. This role involves detailed prepress work, quality assurance, and coordination with production teams and clients.
Responsibilities
- Analyze incoming client design files (AI, PDF, EPS, PSD) for resolution, embedded fonts, linked assets, missing elements, and dielines
- Convert RGB/CMYK files into press-ready separations (Process CMYK + Spot/Pantone colors) tailored to the client's press capacity
- Assess printability by checking for flexo limitations such as text size (positive and reverse), minimum stroke weight, and barcode readability (scaling and truncation rules)
- Apply precise choke/spread trapping values based on substrate and press type (e.g., corrugated, film, label, or woven sack) to prevent misregistration gaps on press
- Apply appropriate dot gain compensation curves (press curve / plate curve) to ensure smooth vignettes and prevent harsh highlight drop-offs
- 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)
- Accurately calculate and apply stretch/distortion percentages along the print cylinder circumference based on plate thickness, sticky-back/tape thickness, and cylinder repeat length
- Set appropriate screen rulings (LPI) and screen angles per separation to avoid moir patterns and ensure clean ink laydown on specific anilox roll configurations
- Build step-and-repeat layouts optimizing polymer plate area utilization while maintaining correct cylinder repeat and web width
- Position essential press aids accurately, including register marks, micro-dots, bearer bars/tracks, eye marks, and color identification patches/slug lines
- Plan split-plate or staggered layouts for corrugated/woven sack printing to minimize plate consumption and mounting stress
- Output calibrated 1-bit TIFFs or RIP workflows through systems like Esko DeskPack/PackEdge/Automation Engine or Kodak/Hybrid software
- Apply specialized screening technologies (e.g., HD Flexo, Crystal screens, Flat-Top Dot surface patterns) appropriate for the specific photopolymer plate grade
- Perform digital 1-bit TIFF soft-proofing (checking traps, overprints, knockout text, and separation channels) prior to laser exposure
- Generate clear 1:1 scale soft proofs (PDFs with separation breakdowns, dimensions, and plate thickness specifications) for customer sign-off
- Verify critical parameters against the job card, including plate thickness, surface or reverse print orientation (emulsion up/down), repeat size, and print width
- Maintain structured file archives with date/revision tags to avoid running obsolete artwork versions on re-orders
