Offset Printing Software with Automatic Colour Separation

Offset printing is the volume workhorse of paper and card: plate-based CMYK that gets cheaper per unit the more you print. FastEditor converts every upload to CMYK, separates and imposes it, applies bleed and trim marks, and outputs a print-ready file matched to the press.

What this technique demands of the artwork

Offset printing gets cheaper per unit at volume, and its constraints come from plates and CMYK rather than colour count.

Colour is CMYK, plus spot where needed. Designs are converted to the press CMYK profile, and Pantone spot colours are mapped where the job calls for them, so what the customer approves is what the press holds.

Resolution and bleed. Artwork is validated at true print size, and bleed, trim and safe margins are applied so nothing important is lost at the cut.

It must be press-ready. Plates are made from clean artwork, so FastEditor vectorises or resolution-checks every upload and imposes the job for the sheet.

  • Automatic CMYK conversion, spot colours mapped where needed
  • Resolution validated at true print size
  • Bleed, trim and safe margins applied automatically
  • Artwork separated and imposed for the press

What FastEditor outputs for production

The printer receives a press-ready CMYK file with bleed, trim marks and imposition applied.

  • File type: press-ready PDF, CMYK, separated
  • Colour: converted to the press profile, spot colours mapped
  • Sizing: scaled and imposed for the press sheet
  • Validation: resolution at true print size, bleed and trim marks
  • Turnaround: generated on proof approval

The production-ready file goes straight to plate-making.

Products decorated this way

Offset printing is the volume choice for paper and card:

  • Brochures and catalogues: long runs where cost per unit matters most.
  • Packaging: folding cartons and printed boxes at scale.
  • Stationery: letterheads, business cards and branded print.

Frequently asked questions

What is offset printing best for?

High-volume paper and card work such as brochures, catalogues, packaging and stationery, where the per-unit cost drops as the run grows.

How is colour handled?

Artwork is converted to the press CMYK profile automatically, and Pantone spot colours are mapped where the job needs them, so approved colour matches the press.

What is imposition?

Arranging multiple pages or copies on the press sheet so it prints and folds correctly. FastEditor imposes the job automatically as part of file prep.

What file does production receive?

A press-ready CMYK file with bleed, trim marks and imposition applied, generated on proof approval.

Does the customer need a vector file?

No. FastEditor vectorises or resolution-checks any upload so the plate is made from clean artwork.

How does offset differ from digital printing?

Offset uses plates and is cheapest at volume; digital has no plates and wins for short runs and variable data. FastEditor outputs the right file for either.
