/ what you get

Six tools that replace hours of manual work.

Each tool was built from a decade of real-world print production experience. Together, they handle 90% of prepress tasks your team does by hand today.

01

Automated Preflight

Catches resolution, color space, font, bleed, and margin issues before they reach the press. Reports rival callas pdfToolbox — at a fraction of the cost.

02

Rich Black Correction

Detects and fixes improperly defined black (K-only) text, converting it to proper rich black (C30 M30 Y30 K100). No more washed-out headlines.

03

Dieline & Cut Contour Processing

Automatically detects punch holes, generates OCG layers with spot colors, and exports Illustrator-compatible files. No more manual layer setup.

04

Intelligent Bleed Generation

Adds 3mm bleeds using content-aware mirror or stretch algorithms. Handles edge cases that trip up basic tools.

05

ICC Color Conversion

Converts RGB to CMYK using industry-standard ICC profiles — Fogra39, GRACoL, SWOP — matched to your specific press and substrate.

06

AI-Powered Image Upscaling

Low-res client files? Real-ESRGAN upscales images up to 4× without artifacts. Runs on your GPU — no cloud dependency, no per-image fees.
