EFI COLORPROOF

Current version: 5.0.1 (since December 19th, 2003)

Hint: If you are going to upgrade from a previous version, please read our technical notes below.

With EFI Colorproof, you output your contract proofs by yourself — on standard and therefore cost-efficient inkjet or laser output systems. That way, you gain flexibility, autonomy and an outstanding proof quality in an affordable fashion.

EFI Colorproof is the contone proofing system for the production environment. It combines three components into an easy-to-use digital proofing solution:

• PostScript-RIP
• integrated ICC color management
• Production and nesting tools
(Rotating, cropping, scaling, tiling...)

EFI Colorproof runs under Windows and offers all network users up to 15 input channels that can be individually configured for quality, color simulation and output media. You can print your files directly on virtual PostScript printers or place them into hot folders. Everything else is automatic. The product supports many printers from A3+ up to 60-inch large-format production devices.

EFI Colorproof is ready for EFI Remoteproof — it imports and exports EFI Remoteproof containers with PDF and JDF data.

  Technical notes for upgraders

• Before installing an upgrade to version 5.0.x, please keep the following in mind:
  
  
• The new 5.0.x linearization procedure is no longer based on densities, but on L*a*b* values. That's why densitometers and some spectral photometers are not supported any longer.
  
• Baselins and paper profiles from previous versions can be used with 5.0.x, but you can't re-linearize them. In our download section, you will find fully compatible profiles for Version 5.0.x and above in a separate area. The list is still growing, so — please check if your printer model in the desired resolution is among them!
  
• Some older printer models are not supported any longer. Please check if your printer is still in the list.
  
• The »banding fix« for Epson x600 devices is har coded in version 5.0.x. Profiles created without »banding fix« will lead to improper color results when used in Version 5.0.x. In this case, please use one of the 5.0.x profiles from the efi download section or create a new profile by yourself.
