Empowering Digital Photographers

MONACO—Digital camera back manufacturer Sinar Bron recently held an international press briefing here. The Mediterranean locale was chosen because it is home to binu-scan, the image processing software developer that has developed a new color-conversion utility for use with Sinar systems.

Sinar CeMagYK (pronounced “see magic”) software was developed in response to the greater opportunities digital photographers have to manipulate images and exercise influence over the printed results, according to company management. The conversion software works as a plug-in to Sinar’s CaptureShop image processing software and is billed as a professional prepress tool for preparing ready-to-print digital images.

The core of the CeMagYK software is the IPM (Image Processing Machine) from binuscan. The IPM reportedly enhances printed image quality through the application of special conversion tables, adaptive unsharp masking and a contrast-optimizing technique.

The RGB to CMYK look-up tables (LUTs) are said to be based on binuscan’s extensive color expertise that is rooted in its genesis from the Binucci Printing House in Monaco. The LUTs were optimized for strong, saturated color tones in RGB, which offers advantages for photography of plastic parts and product shots. According to Sinar, CeMagYK also achieves life-like results in skin tones.

The adaptive unsharp masking function takes into account the scaled size of the picture and is tailored to the printing process. The contrast function is said to adjust all three (RGB) color channels to ensure that the full brightness level is reproduced. A batch processing feature enables all processing functions of CeMagYK to be applied simultaneously to several pictures with a single command.

The software supports common image data formats, but Jean-Marie Binucci, binuscan’s president, recommends that PostScript-based formats be used for print workflows. He contends that the DCS file formats offer several advantages, especially compared to TIFF, in terms of workflow and quality control.
