Pre-press

Before a map appears as a final product, all processes before printing are controlled and adjusted in a digital workflow. Thus the data is modified and converted into high-resolution data formats for print and online media using different RIP processes.

Data conversion and data processing of output data for print (CtP) or online

imposition (atlases)

• creation of imposition template, according to requirement
• page preparation
• preparation of the whole print forms

PDF

• PDF, PDF-X, or by agreement
• CMYK process scale and/or special colours
• colour information controlled, colour models and colour spaces (ISO / ICC)
   

1-bit TIFF Group4

• 1 record per colour separation, unlimited number
• CMYK process scale and/or special colours
• periodic screening from 35 P/cm to 90 P/cm
• non-periodic screening: FM or AM-stochastic
• geometric resolution by agreement
• compensation curves taken into account, depending on reference print

Vector data

• various exchange formats by agreement

Raster data

• various data formats (e.g. TIFF, GIF)
• geometric resolutions (e.g. 254 dpi, 1016 dpi)
• radiometric resolutions (e.g. 8-bit, 24-bit RGB, 32-bit CMYK)
• colour information controlled, colour models and colour spaces (ISO / ICC)

Data transfer

• depending on volume of data, by agreement
• by email
• FTP-Server, access data by email
• CD, DVD
• contact

Colour management

Colour management

• adherence and regulated adjustment of colour information through the overall work flow

Repeatability

• Periodic updating of cartographic products
• ensures reproducibility

Quality assurance

• adherence to recognised norms and standards (ISO)
• objective examination, quality certificate with suitable measuring techniques (spectrophotometer, verification software)
• addition of self-defined tolerances and agreements (special colours, several print passes)
• systematic controls with soft proofs, digital proofs on different paper or film

Proofing
Production of digital proofs – contract proofs – raster proofs

System EFI Colourproof XF / Epson Stylus Pro 9800 with colour management

According to record and requirements, the approximation is:

• content accurateh
• colour accurate, according to print condition: relative or absolute colorimetric
• colour structure accurate: unlimited number of separations
• screen accurate (with 1-bit Tiff): periodic screening up to 60 P/cm as well as non-periodic screening visually discernable
