Optimized files for problem-free printing:
PDF files come from a variety of sources; they contain elements having different color spaces and separation options. These files need to be harmonized and adapted to suit the printer's actual printing conditions to ensure accurate rendering of the approved proofs.
Alwan CMYK Optimizer allows a pre-press company or printer to check and correct automatically and dynamically the colors and ink weight characteristics of incoming files, before sending them for film or plate output. It can be used with any four-color process (+ spots) regardless of the output technology so is suitable for litho, flexo, gravure, digital, screen etc. The hotfolder-based system offers automatic and dynamic dot gain compensation, TAC correction and black generation for optimal printing.
In everyday production, the printer has to deal with files received from different sources that do not print well on the press. This may be due to a variety of reasons, such as a mismatch between color separation and press profile or between the black generation in the file and the optimal black generation for the used process, or between ink values in the file and press and paper requirements.
Overmore, printers often do not know a long way in advance on which press a job will be produced. Therefore, it is not possible to use the press profile for the CMYK separation on the pre-press system. The stock to be used on a job is sometimes chosen or changed at the last minute depending on price or availability, color and dot gain reproduction can vary dramatically accordingly.
The benefits of using Alwan CMYK Optimizer include:
