The PDF tool offered from the end of October provides extended features for professional color conversion which not only fulfill highest demands for printing, but also help to save ink and keep presses clean, by reducing ink application.
Berlin, October 4th, 2007. The universal tool for professional color conversion of PDF documents – pdfColorConvert by callas software – has now become even more indispensable for prepress operators, newspapers and commercial printers: The latest “PRO” version will be shipped with integrated DeviceLink profiles and provides an option for tonal corrections via gradation adjustment as well as a conversion of CMYK and spot colors to RGB. callas software is to present the new pdfColorConvert PRO at IFRA Expo 2007 in Vienna, Austria, from October 8 to October 11. pdfColorConvert PRO, which will be launched end of October 2007, offers a range of new, advanced features, which make the tool more effective for professional use. Especially users who often or constantly change the ink build-up of entire PDF pages or who have to adapt it to other printing conditions will be pleased: With the latest pdfColorConvert PRO – being available as a plug-in in Acrobat Standard or Professional, individually or as a command-line module (pdfColorConvert PRO CLI) – callas software offers a tool that allows for the automated adaptation of PDF files to the most diverse printing conditions.
Prepress companies and printers are increasingly confronted with the problem that the PDF files submitted by the customer should be flexibly used for a whole range of printing jobs. The same template should be used for an ad in a newspaper today and on the next day, be printed in a journal on a different offset press. To always deliver first quality, the PDF printing files must be adapted to the specific printing conditions. So the printer needs to optimize the color space, the total ink application, and the dot gain for each printout. However, a color conversion using ICC profiles does hardly produce ideal results when performing a CMYK-to-CMYK conversion: The original separation will be lost during the color conversion via the three-color CIELab color space, the black channel generation will be four-color, and gradations will show tears. A remedy to this scenario are color conversions with specially adapted DeviceLink profiles which are included for all common printing processes in pdfColorConvert PRO and which are readily available.
The new pdfColorConvert PRO supports and offers DeviceLink profiles for balanced color conversions, while retaining the black channel at the same time. pdfColorConvert PRO's integrated DeviceLink profiles for use within the program have been specially designed for the conversion and optimization of four-color PDF files and ensure color space adaptation, tonal limitation, and the preservation of pure colors. pdfColorConvert PRO, when combined with DeviceLink profiles, also allows you to optimally define the total ink application for each selected printing condition, which is not the case for most ICC profiles. Often, ICC profiles are used which are far in excess of the best-possible value for the press in question and lead to contamination, an increased drying time of the paper and last but not least an increased ink consumption. Users can, of course, choose to apply DeviceLink profiles in pdfColorConvert PRO which are in addition optimized for ink reduction. pdfColorConvert PRO can therefore considerably contribute to saving ink and time, reducing costs, and keeping the press clean and functioning.
At the same time, pdfColorConvert PRO with its integrated DeviceLink profiles also avoids printing problems with PDF pages which have been created with transparency effects and which have been flattened on PDF file generation. Single objects are often stripped down to multiple objects like images, text, and vector graphics to reproduce the visual appearance without having a transparency feature. If the user subsequently color-converts those pages, this will inevitably lead to inking fluctuations and contamination of pure colors in the previously transparent objects. pdfColorConvert PRO however guarantees the optimal adjustment of colors, without resulting in ink build-up problems or even color gradations which haven't existed before.
Another new feature which has often been requested by users is the gradation correction which is, for example, required when the users adjusts the dot gain to papers with extremely high or extremely low dot gains for printing and doesn't want to create a separate RIP curve for that. pdfColorConvert PRO provides an option to enter a compensation value for the halftone at 40% which serves as a basis value for the calculation of the gradation curve that is applied to the data. The pdfColorConvert PRO CLI command-line version can limit this gradation adjustment to primary, secondary, and tertiary colors or define a graduated gradation curve with tonal limitation.
The new pdfColorConvert PRO also offers the function to convert PDF files which consist of CMYK and/or spot colors to RGB, for later use on the Internet, for example. This is why pdfColorConvert PRO with its extremely user-friendly interface has become the unbeatable support for professionals in the print industry. With a few clicks and optimally preset configuration files in the CLI version, this tool allows for professional color management for everybody.
pdfColorConvert PRO will be available as a plug-in for Acrobat Standard or Professional 7 and 8 on Windows 2000, Vista, and MAC OS X as well as a command-line module (pdfColorConvert CLI) for all common server platforms.
