To promote digital photography, EPSON announces the revolutionary PRINT Image Matching Technology which can produce printout with outstanding quality better than those produced by the conventional film and photo printer. Many of the Digital Still Camera (DSC) users love to print digital photos from their home PCs. PRINT Image Matching technology can help to demonstrate the true capacity of their DSCs.

Digital Photo Printing is More Convenient

Most of the conventional camera users find it difficult to have a prefect photo. While shooting technique is vital, quality of photo still depends heavily on the use of camera, films, films development procedures, photo paper and so on.
Digital photography is much more convenient instead, DSC users only need to print their pictures through their printers. Quality of digital photo however, remains the most concerned question.

Traditional Digital Photo Printing Fails to Reflect the True Quality of Digital Image

Conventional image-processing technology cannot produce printouts reflecting the original digital image. The problem aroused because while digital camera uses YCbCr format to store image data, the CRT monitor of a personal computer uses a narrower colour space - sRBG. When image data is transferred from DSC to a sRBG personal computer, the original colour data in YCbCr format will be uniformly compressed into an sRBG framework, resulting in the loss of colour information, especially in the natural blue-green colour range. Colours of the reproduced image and the original will therefore be very different when image data is transmitted to printer after PC processing.

PRINT Image Matching Technology Ensures the True Quality of Digital Photography

When an image is captured, the PRINT Image Matching-enabled digital camera will store the original gamma value, colour space and image adjustment parameters of the captured image into the JPEG File Header. No matter which model of DSCs is used, the same storage method would apply if the digital camera supports PRINT Image Matching technology. Meanwhile, when a digital image is transmitted to PCs, the original image data stored in YCbCr format will not be transformed into sRBG values in the PC, thus preventing any loss of data.

The originally captured image can also be modified by using EPSON PhotoQuicker 3.2, which is a PRINT Image Matching-compatible software for photo editing, then the photos can be printed by PRINT Image Matching-compatible ink jet printer as it can read the information of the Header in JPEG format. Finally, a faithful image reproduction of the original shot can be produced.

Benefits to Users

PRINT Image Matching technology is beneficial to both professional and general digital camera users. To the professionals, PRINT Image Matching allows them to produce printouts with prefect quality in promotion materials. With digital camera and printer compatible with PRINT Image Matching technology, consistent digital photo prints can be achieved and the users do not have to worry alternation of colours due to the use of different brands or models of printers and cameras anymore.

To the general users, PRINT Image Matching technology enables them to produce high quality printouts easily. In order to obtain picture with superb quality, they are simply required to adjust the shutter and aperture. General users can therefore fully enjoy the fun in shooting with digital cameras as it is no longer necessary for them to make any adjustment in their PCs afterward.
