 Alwan CMYK Optimizer server is the first preflight, standardization and optimization software for CMYK separations and data. It helps pre-media and prepress companies produce printable files, and allows printers to control and improve the printability of the files they receive by optimizing their separation for the destination process/press/paper. The files made compliant using CMYK Optimizer generate reproducible proofs as well as plates and cylinders with improved printability on the press. Alwan solutions are all based on open standards like ICC Profiles and formats like PDF, TIFF, JPEG, etc. and are also easy to integrate into other workflow solutions as they are hot folder based. |
Addressed Problems
Printability issues
In everyday jobs, the printer has to deal with situations where the client files do not print well enough or fast enough on press. This causes delays on press to achieve the right rendering (which is not always possible) and generates considerable losses in machine time and waste (and client dissatisfaction).
This is due to:
• Mismatch between incoming files color separation profile and printing press profile
• The ink values (Total Area Coverage TAC) contained in the files not being appropriate for the destination press and paper which in turn causes ink set-off and dirt
• Mismatch between incoming files black generation and printer desired or optimal black generation (GCR/UCR...)
• Mismatch between incoming files separation dot gain and printing substrate actual dot gain
Practical issues
Implementing ICC color management remains tedious in multi-press and multi-process environments. An individual ICC profile for each press and paper is technically right but practically not feasible nor necessary to achieve very good and consistent results on the press:
• A printer does not always know long in advance on which press a job will be printed. Therefore in these cases it is not possible to use the actual press profile for CMYK separation during DTP production
• Paper can be chosen or changed at the last minute depending on price, availability etc. Dot gain can vary dramatically between papers, even of the same category.
| | Benefits
• Output files made compliant to the printing process/press/paper requirements
• Improved printability and shorter make ready time
• Improved color rendering and quality
• Better match with color managed proofs
• Solves all set-off and dirt problems due to high ink weights
• Easier and more stable printing
• Up to 30% ink savings with Alwan Ink Saving technology
• Uses Alwan LinkProfiler technology to build high quality ICC Device Link Profiles. Alwan DeviceLink Profiles are among the best ICC DeviceLink Profiles available today and are used in demanding production environments to produce ICC based prints for multi-million circulation products and titles.
